"Find the equation of the horizontal asymptote for y = 12(1 + 5−x)"

The derivative of the function f(w) = cos(sin^(-1)(7w)) is given by f'(w) = -7cos(w)/√(1-(7w)^2).

To find the derivative of f(w), we can use the chain rule. Let's break down the function into its composite parts. The inner function is sin^(-1)(7w), which represents the arcsine of (7w).

The derivative of arcsin(u) is 1/√(1-u^2), so the derivative of sin^(-1)(7w) with respect to w is 1/√(1-(7w)^2) multiplied by the derivative of (7w) with respect to w, which is 7.

Next, we need to differentiate the outer function, cos(u), where u = sin^(-1)(7w). The derivative of cos(u) with respect to u is -sin(u). Plugging in u = sin^(-1)(7w), we get -sin(sin^(-1)(7w)).

Combining these derivatives, we have f'(w) = -7cos(w)/√(1-(7w)^2). The negative sign comes from the derivative of the outer function, and the remaining expression is the derivative of the inner function. Thus, this is the derivative of the given function f(w).

The shooting method is used to solve the second-order ordinary differential equation 7d^2y/dx^2 - 2dy/dx - yx = 0 with the boundary conditions y(0) = 5 and y(20) = 8.

To solve the differential equation using the shooting method, we convert it into a system of two first-order equations. Let y = y0 and z = dy/dx, where z represents the derivative of y with respect to x. Then, we have the following system:

dy/dx = z

dz/dx = (2z + yx) / 7

By specifying the initial condition y(0) = 5, we have y0 = 5. To find the appropriate initial condition for z, we use the shooting method. We start by assuming an initial condition for z, say z0, and solve the above system of equations from x = 0 to x = 20. We compare the value of y at x = 20 with the desired boundary condition y(20) = 8.

If the value of y at x = 20 is greater than 8, we adjust the initial condition z0 and repeat the process. If the value is less than 8, we increase z0 and repeat. By iteratively adjusting the initial condition for z, we find the appropriate value that satisfies y(20) = 8.

The flux of the vector field F = (y, -z) across the part of the plane z = 1 + 4x + 3y above the rectangle [0, 3] *[0, 4] with upward orientation is given by: [tex]$$\text{Flux} = 36\sqrt{26} + 144x\sqrt{26} + 108y\sqrt{26} - 96\sqrt{26}$$[/tex]

To find the flux of the vector field F = (y, -z) across the given plane, we need to evaluate the surface integral over the rectangular region.

Let's parameterize the surface by introducing the variables x and y within the specified ranges. We can express the surface as [tex]$\mathbf{r}(x, y) = (x, y, 1 + 4x + 3y)$[/tex], where [tex]$0 \leq x \leq 3$[/tex] and [tex]$0 \leq y \leq 4$[/tex]. The normal vector to the surface is [tex]$\mathbf{n} = (-\partial z/\partial x, -\partial z/\partial y, 1)$[/tex].

To calculate the flux, we use the formula:

[tex]$$\text{Flux} = \iint_S \mathbf{F} \cdot \mathbf{n} \, dS$$[/tex]

where dS represents the differential area element on the surface S.

First, we need to calculate $\mathbf{n}$:

[tex]$$\frac{\partial z}{\partial x} = 4, \quad \frac{\partial z}{\partial y} = 3$$[/tex]

So, [tex]$\mathbf{n} = (-4, -3, 1)$[/tex].

Next, we compute the dot product [tex]$\mathbf{F} \cdot \mathbf{n}$[/tex]:

[tex]$$\mathbf{F} \cdot \mathbf{n} = (y, -z) \cdot (-4, -3, 1) = -4y + 3z$$[/tex]

Now, we need to find the limits of integration for the surface integral. The surface is bounded by the rectangle [0, 3] * [0, 4], so the limits of integration are [tex]$0 \leq x \leq 3$[/tex] and [tex]$0 \leq y \leq 4$[/tex].

The flux integral becomes:

[tex]$$\text{Flux} = \iint_S \mathbf{F} \cdot \mathbf{n} \, dS = \int_0^4 \int_0^3 (-4y + 3z) \left\lVert \frac{\partial \mathbf{r}}{\partial x} \times \frac{\partial \mathbf{r}}{\partial y} \right\rVert \, dx \, dy$$[/tex]

The cross product of the partial derivatives [tex]$\frac{\partial \mathbf{r}}{\partial x}$[/tex] and [tex]$\frac{\partial \mathbf{r}}{\partial y}$[/tex] yields:

[tex]$$\frac{\partial \mathbf{r}}{\partial x} \times \frac{\partial \mathbf{r}}{\partial y} = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ 1 & 0 & 4 \\ 0 & 1 & 3 \end{vmatrix} = (-4, -3, 1)$$[/tex]

Taking the magnitude, we obtain [tex]$\left\lVert \frac{\partial \mathbf{r}}{\partial x} \times \frac{\partial \mathbf{r}}{\partial y} \right\rVert = \sqrt{(-4)^2 + (-3)^2 + 1^2} = \sqrt{26}$.[/tex]

We can now rewrite the flux integral as:

[tex]$$\text{Flux} = \int_0^4 \int_0^3 (-4y + 3z) \sqrt{26} \, dx \, dy$$[/tex]

To evaluate this integral, we first integrate with respect to x:

[tex]$$\int_0^3 (-4y + 3z) \sqrt{26} \, dx = \sqrt{26} \int_0^3 (-4y + 3z) \, dx$$$$= \sqrt{26} \left[ (-4y + 3z)x \right]_{x=0}^{x=3}$$$$= \sqrt{26} \left[ (-4y + 3z)(3) - (-4y + 3z)(0) \right]$$$$= \sqrt{26} \left[ (-12y + 9z) \right]$$[/tex]

Now, we integrate with respect to $y$:

[tex]$$\int_0^4 \sqrt{26} \left[ (-12y + 9z) \right] \, dy$$$$= \sqrt{26} \left[ -6y^2 + 9yz \right]_{y=0}^{y=4}$$$$= \sqrt{26} \left[ -6(4)^2 + 9z(4) - (-6(0)^2 + 9z(0)) \right]$$$$= \sqrt{26} \left[ -96 + 36z \right]$$[/tex]

Finally, we have:

[tex]$$\text{Flux} = -96\sqrt{26} + 36z\sqrt{26}$$[/tex]

Since the surface is defined as z = 1 + 4x + 3y, we substitute this expression into the flux equation:

[tex]$$\text{Flux} = -96\sqrt{26} + 36(1 + 4x + 3y)\sqrt{26}$$[/tex]

Simplifying further:

[tex]$$\text{Flux} = -96\sqrt{26} + 36\sqrt{26} + 144x\sqrt{26} + 108y\sqrt{26}$$[/tex]

Hence, the flux of the vector field F = (y, -z) across the part of the plane z = 1 + 4x + 3y above the rectangle [0, 3] *[0, 4] with upward orientation is given by:

[tex]$$\text{Flux} = 36\sqrt{26} + 144x\sqrt{26} + 108y\sqrt{26} - 96\sqrt{26}$$[/tex]

(a) The argument of z, given z = (a + ai)(b√3 + bi), is arg [tex]z = tan^{(-1)}[/tex]((√3 + 1) / (√3 - 1)) and (b) The cube roots of -32 + 32√3i are 4 * [cos(-π/9) + isin(-π/9)], 4 * [cos(5π/9) + isin(5π/9)], and 4 * [cos(7π/9) + isin(7π/9)].

(a) To determine arg z, we need to find the argument (angle) of the complex number z. Given that z = (a + ai)(b√3 + bi), we can expand this expression as follows:

z = (a + ai)(b√3 + bi) = ab√3 + abi√3 + abi - ab

Simplifying further, we have:

z = ab(√3 + i√3 + i - 1)

Now, we can write z in polar form by finding its magnitude (modulus) and argument. The magnitude of z is given by:

[tex]|z| = \sqrt(Re(z)^2 + Im(z)^2)[/tex]

Since z = ab(√3 + i√3 + i - 1), the real part Re(z) is ab(√3 - 1), and the imaginary part Im(z) is ab(√3 + 1). Therefore, the magnitude of z is:

[tex]|z| = \sqrt((ab(\sqrt3 - 1))^2 + (ab(\sqrt3 + 1))^2) = ab\sqrt(4 + 2\sqrt3)[/tex]

To find the argument arg z, we can use the relationship:

arg z = [tex]tan^{(-1)}[/tex](Im(z) / Re(z))

Substituting the values, we have:

arg z = tan^(-1)((ab(√3 + 1)) / (ab(√3 - 1))) = [tex]tan^{(-1)}[/tex]((√3 + 1) / (√3 - 1))

Therefore, the argument of z is arg z = [tex]tan^{(-1)}[/tex]((√3 + 1) / (√3 - 1)).

(b) To find the cube roots of -32 + 32√3i, we can write it in polar form as:

-32 + 32√3i = 64(cosθ + isinθ)

where θ is the argument of the complex number.

The modulus (magnitude) of -32 + 32√3i is:

| -32 + 32√3i | = √((-32)^2 + (32√3)^2) = √(1024 + 3072) = √4096 = 64

The argument θ can be found using:

θ = arg (-32 + 32√3i) = [tex]tan^{(-1)}[/tex]((32√3) / (-32)) = tan^(-1)(-√3) = -π/3

Now, to find the cube roots, we can use De Moivre's theorem:

[tex]z^{(1/3)} = |z|^{(1/3)}[/tex]* [cos((arg z + 2kπ)/3) + isin((arg z + 2kπ)/3)]

Substituting the values, we have:

Cube root 1: [tex]64^{(1/3)}[/tex] * [cos((-π/3 + 2(0)π)/3) + isin((-π/3 + 2(0)π)/3)]

Cube root 2: [tex]64^{(1/3)}[/tex] * [cos((-π/3 + 2(1)π)/3) + isin((-π/3 + 2(1)π)/3)]

Cube root 3: [tex]64^{(1/3)}[/tex] * [cos((-π/3 + 2(2)π)/3) + isin((-π/3 + 2(2)π)/3)]

Simplifying further, we have:

Cube root 1: 4 * [cos(-π/9) + isin(-π/9)]

Cube root 2: 4 * [cos(5π/9) + isin(5π/9)]

Cube root 3: 4 * [cos(7π/9) + isin(7π/9)]

These are the cube roots of -32 + 32√3i. To sketch them in the complex plane (Argand diagram), plot three points corresponding to the cube roots [tex](-32 + 32 \sqrt 3i)^{(1/3)}[/tex] using the calculated values.

The power series Σ (3x + 2)^n / (3n√(n + 1)), where n ranges from 1 to infinity, can be analyzed to determine its radius of convergence and interval of convergence.

To find the radius of convergence, we can use the ratio test. Applying the ratio test, we evaluate the limit of the absolute value of the ratio of consecutive terms as n approaches infinity:

lim (n→∞) |((3x + 2)^(n+1) / ((3(n + 1))√((n + 2) + 1))| / |((3x + 2)^n / (3n√(n + 1)))|

Simplifying this expression, we get:

lim (n→∞) |(3x + 2) / 3| * |√((n + 1) / (n + 2))|

Taking the absolute value of (3x + 2) / 3 gives |(3x + 2) / 3| = |3x + 2| / 3. The limit of |√((n + 1) / (n + 2))| as n approaches infinity is 1.

Therefore, the ratio simplifies to:

lim (n→∞) |3x + 2| / 3

For the series to converge, this limit must be less than 1. Hence, we have:

|3x + 2| / 3 < 1

Solving this inequality, we find -1 < 3x + 2 < 3, which leads to -2/3 < x < 1/3.

Therefore, the interval of convergence is (-2/3, 1/3), and the radius of convergence is 1/3.

To determine the radius of convergence and the interval of convergence of the given power series, we apply the ratio test. By evaluating the limit of the absolute value of the ratio of consecutive terms, we simplify the expression and find that it reduces to |3x + 2| / 3. For the series to converge, this limit must be less than 1, resulting in the inequality -2/3 < x < 1/3. Hence, the interval of convergence is (-2/3, 1/3). The radius of convergence is determined by the distance from the center of the interval (which is 0) to either of the endpoints, giving us a radius of 1/3.

The smallest number a such that A + BB is regular for all B > a can be determined by finding the eigenvalues of the matrix A. The value of a will be greater than or equal to the largest eigenvalue of A.

A matrix A is regular if it is non-singular, meaning it has a non-zero determinant. We can consider the expression A + BB as a sum of two matrices. To ensure A + BB is regular for all B > a, we need to find the smallest value of a such that A + BB remains non-singular. One way to check for singularity is by examining the eigenvalues of the matrix A. If the eigenvalues of A are all positive, it means that A is positive definite and A + BB will remain non-singular for all B. In this case, the smallest number a can be taken as zero. However, if A has negative eigenvalues, we need to choose a value of a greater than or equal to the absolute value of the largest eigenvalue of A.

The value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ) is given by ln(2)^2 / λ.

To derive the value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ), we can start by defining the average life.

The average life (t_average) of unstable nuclei represents the average time it takes for half of the original sample of nuclei to decay. It is closely related to the concept of the half-life of a radioactive substance.

Let's denote N(t) as the number of nuclei remaining at time t, and N₀ as the initial number of nuclei at time t = 0.

The decay of unstable nuclei can be described by the differential equation:

dN(t)/dt = -λN(t)

This equation states that the rate of change of the number of nuclei with respect to time is proportional to the number of nuclei present, with a proportionality constant of -λ (the negative sign indicates decay).

Solving this differential equation gives us the solution:

N(t) = N₀ * e^(-λt)

Now, let's find the time t_half at which half of the original nuclei have decayed. At t = t_half, N(t_half) = N₀/2:

N₀/2 = N₀ * e^(-λt_half)

Dividing both sides by N₀ and taking the natural logarithm:

1/2 = e^(-λt_half)

Taking the natural logarithm of both sides:

ln(1/2) = -λt_half

Using the property of logarithms, ln(1/2) = -ln(2):

ln(2) = λt_half

Now, we can solve for t_half:

t_half = ln(2) / λ

The average life (t_average) is defined as the average time it takes for half of the nuclei to decay. Since we are considering an exponential decay process, the average life is related to the half-life by a factor of ln(2):

t_average = t_half * ln(2)

Substituting the expression for t_half, we have:

t_average = (ln(2) / λ) * ln(2)

Simplifying further:

t_average = ln(2)^2 / λ

Therefore, the value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ) is given by ln(2)^2 / λ.

Thus, $f = [tex]u \cdot v = d \cdot u_1 \cdot d \cdot v_1[/tex] = [tex]d^2 \cdot u_1 \cdot v_1\$[/tex].

Hence d must divide f, which means that d is a non-zero prime divisor of f and g, contradicting that f and g are relatively prime.

Thus, there do not exist non-zero prime polynomials u(x) and v(x) in F[x] with $u(x)|f(x)$ and $v(x)|g(x)$ such that $f(x) = u(x)v(x)$.

Hence, proved.

The Divergence Theorem, also known as Gauss's Theorem, relates the flow of a vector field through a closed surface to the divergence of the field within the volume enclosed by the surface.

Let S be a closed surface that encloses a solid region V in space, and let n be the unit outward normal vector to S. Then, for a vector field F defined on V that is sufficiently smooth, the Divergence Theorem states that:

∫∫S F · n ds = ∭V ∇ · F dV

where the left-hand side is the flux of F across S (i.e., the amount of F flowing outward through S per unit time), and the right-hand side is the volume integral of the divergence of F over V.

To apply this theorem, we need to compute both sides of the equation. Let's start with the volume integral:

∭V ∇ · F dV

Using the product rule for divergence, we can write this as:

∭V (∇ · F) dV + ∭V F · (∇ dV)

The second term vanishes because ∇ dV = 0 (since V is a fixed volume), so we are left with:

∭V (∇ · F) dV

This integral gives us the total amount of "source" or "sink" of F within V, where a positive value means that there is more flow leaving V than entering it, and vice versa.

Now let's compute the flux integral:

∫∫S F · n ds

To evaluate this integral, we need to parameterize S using two variables (say u and v), and express both F and n in terms of these variables. Then we can use a double integral to integrate over S.

In general, the Divergence Theorem provides a powerful tool for computing flux integrals and relating them to volume integrals.

It is widely used in physics and engineering to solve problems involving fluid flow, electric and magnetic fields, and other vector fields.

This equation represents the solution to the given initial-value problem.

To solve the initial-value problem y'' + y = δ(t − 6π) + δ(t − 8π), y(0) = 1, y'(0) = 0 using the Laplace transform, we first take the Laplace transform of the given differential equation and apply the initial conditions. Then we solve for Y(s), the Laplace transform of y(t), and finally use the inverse Laplace transform to find the solution y(t).

Applying the Laplace transform to the given differential equation y'' + y = δ(t − 6π) + δ(t − 8π) yields the equation [tex]s^2Y(s) + Y(s) = e^{(-6\pi s)} + e^{(-8\pi s)}[/tex].

The arc length of the arc UV in terms of pi is (θ/360°) × (60π), where θ represents the Central angle of the arc

In the given scenario, a circle T is shown with a radius of 30 cm. We need to determine the arc length of the arc UV in terms of pi.

The arc length of a circle is given by the formula:

Arc Length = θ/360° × 2πr,

where θ is the central angle of the arc and r is the radius of the circle.

Since the central angle θ of the arc UV is not provided, we cannot calculate the exact arc length. However, we can still express it in terms of pi.

To do this, we need to find the ratio of the central angle θ to the full angle of a circle, which is 360 degrees. We can express this ratio as:

θ/360° = Arc Length/(2πr).

Substituting the given radius value of 30 cm into the equation, we have:

θ/360° = Arc Length/(2π × 30).

Simplifying, we get:

θ/360° = Arc Length/(60π).

Now, if we express the arc length in terms of pi, we can rewrite the equation as:

θ/360° = (Arc Length/π)/(60π/π).

θ/360° = (Arc Length/π)/(60).

θ/360° = Arc Length/(60π).

From the equation, we can see that the arc length in terms of pi is equal to θ/360° multiplied by (60π).

Therefore, the arc length of the arc UV in terms of pi is (θ/360°) × (60π), where θ represents the central angle of the arc. Without additional information about the central angle, we cannot provide an exact numerical value for the arc length in terms of pi. time is a multifaceted and pervasive element of human existence.

Answer: 30t + 450 = 30t

Step-by-step explanation:

To calculate Xavier's average speed, we need to determine the time it took for him to travel from Terminal A to Terminal B. Let's assume Xavier's time is represented by "t" minutes.

Since Henry left Terminal A 15 minutes earlier than Xavier, we can express Henry's time as "t + 15" minutes.

We are given that when Xavier reached Terminal B, Henry had completed 2/3 (or 2/3 * 100% = 66.67%) of his journey and was 30 km away from Terminal B.

Since Xavier has completed the entire journey, the distance he traveled is the same as the remaining distance for Henry, which is 30 km.

Now, let's set up a proportion using the time and distance for Xavier and Henry:

t/(t + 15) = 30/30

Cross-multiplying the proportion:

30(t + 15) = 30t

Simplifying the equation:

30t + 450 = 30t

We can see that the "t" terms cancel out, resulting in 450 = 0, which is not possible.

The quotient is:[tex]x^{(n-1)} + x^{(n-2)}a + ... + a^{(n-1)}n * a^{(n-1)} = n * a^{(n-1)(x-a) }+ x^n - a^n[/tex] by the factor theorem.

In order to show that [tex]x^n - a^n[/tex] has a factor x - a, we can observe that we have to prove that if x = a, then [tex]x^n - a^n[/tex] equals zero.

Therefore, we can write:

[tex]x^n - a^n = x^n - a^n + 2a^n - 2a^n= (x^n - a^n) + (2a^n - 2a^n)= (x - a)(x^(n-1) + x^(n-2)a + ... + a^(n-1))[/tex]

The second part of the question is asking for the quotient (x^n — a^n)/(x − a).

By the factor theorem, [tex]x^n - a^n[/tex] can be written as (x - a)Q(x) + R, where Q(x) and R are polynomials such that the degree of R is less than the degree of x - a.

If we divide both sides of this equation by x - a, we get:

[tex]x^n - a^n = (x - a)Q(x) + Rx^{(n-1)} - a^{(n-1)} = (x - a)(Q(x) + (x^{(n-1)} + x^{(n-2)}a + ... + a^{(n-1)})/(x - a))[/tex]

Let [tex]S(x) = (x^{(n-1)} + x^{(n-2)}a + ... + a^{(n-1)})/(x - a)[/tex]. As x approaches a, S(x) approaches [tex]n * a^{(n-1)[/tex].

Therefore, the quotient is:[tex]x^{(n-1)} + x^{(n-2)}a + ... + a^{(n-1)}n * a^{(n-1)} = n * a^{(n-1)(x-a) }+ x^n - a^n[/tex].

The degree of the Maclaurin polynomial required is n = 6.

The given series is Σ0.3^n, where n starts from 0. We want to determine the degree of the Maclaurin polynomial required to approximate this series with an error less than 0.0001.

To find the degree of the Maclaurin polynomial, we need to consider the error bound using Taylor's inequality. The error bound is given by the (n+1)th derivative of the function evaluated at a point multiplied by (x-a)^(n+1), divided by (n+1)!. In this case, a is 0, and we want the error to be less than 0.0001.

Let's consider the (n+1)th derivative of the function f(x) = 0.3^x. Taking derivatives, we have:

f'(x) = ln(0.3) * 0.3^x

f''(x) = ln(0.3)^2 * 0.3^x

f'''(x) = ln(0.3)^3 * 0.3^x

We can observe that as we take higher derivatives, the value of ln(0.3)^k * 0.3^x decreases for any positive integer k. To ensure the error is less than 0.0001, we need to find the smallest value of n such that:

|f^(n+1)(x)| * (0.3)^(n+1) / (n+1)! < 0.0001

Since the value of ln(0.3) is negative, we can take its absolute value. Solving this inequality for n, we find:

|ln(0.3)^(n+1) * 0.3^(n+1)| / (n+1)! < 0.0001

Now, we can evaluate the inequality for different values of n to determine the smallest value that satisfies the condition.

After evaluating the inequality for n = 3, n = 4, n = 5, and n = 6, we find that only n = 6 satisfies the condition, making the error in the approximation less than 0.0001. Therefore, the degree of the Maclaurin polynomial required is n = 6.

In this solution, we are given the series Σ0.3^n, and we want to determine the degree of the Maclaurin polynomial required to approximate the series with an error less than 0.0001.

Using Taylor's inequality, we calculate the (n+1)th derivative of the function and observe that the magnitude of the derivative decreases as we take higher derivatives.

To ensure the error is less than 0.0001, we set up an inequality and solve for the smallest value of n that satisfies the condition. After evaluating the inequality for n = 3, n = 4, n = 5, and n = 6, we find that only n = 6 satisfies the condition, indicating that a degree 6 Maclaurin polynomial is required for the desired level of accuracy.

Therefore, the answer is (A) n = 6.

The expression that gives the area under the curve as a limit, using right endpoints, can be written as: A = lim(n->∞) ∑[i=1 to n] f(xi)Δx

where A represents the area under the curve, n represents the number of subintervals, xi represents the right endpoint of each subinterval, f(xi) represents the function evaluated at the right endpoint, and Δx represents the width of each subinterval.

In this specific case, the curve is given by f(x) = x² from x = 0 to x = 1. To find the area under the curve, we can divide the interval [0, 1] into n equal subintervals of width Δx = 1/n. The right endpoint of each subinterval can be expressed as xi = iΔx, where i ranges from 1 to n. Therefore, the expression for the area under the curve becomes:

A = lim(n->∞) ∑[i=1 to n] (xi)² * Δx

This expression represents the limit of the sum of the areas of the right rectangles formed by the function evaluated at the right endpoints of the subintervals, as the number of subintervals approaches infinity. Evaluating this limit would give us the exact area under the curve, but the expression itself allows us to approximate the area by taking a large enough value of n.

The function has no points of inflection. The largest open interval where the function is concave upward is (-∞, +∞).

To find the intervals of concavity and points of inflection, we first need to find the second derivative of the given function f(x) = 4x² + 5x² – 3x + 3.

First, let's find the first derivative f'(x):
f'(x) = 8x + 10x - 3

Now, let's find the second derivative f''(x):
f''(x) = 8 + 10

f''(x) = 18 (constant)

Since the second derivative is a constant value (18), it means the function has no points of inflection and is always concave upward (as 18 > 0) on its domain. Therefore, the largest open interval where the function is concave upward is (-∞, +∞). There are no intervals where the function is concave downward.

The differential dy of y = tan(x) is given by dy = sec^2(x) dx. Evaluating dy for x = π/4 and dx = -0.1 gives approximately dy = -0.2005.

To find the differential dy of y = tan(x), we differentiate the function with respect to x using the derivative of the tangent function. The derivative of tan(x) is sec^2(x), where sec(x) represents the secant function.

Therefore, we have dy = sec^2(x) dx as the differential of y.

To evaluate dy for a specific point, in this case, x = π/4 and dx = -0.1, we substitute the values into the differential equation. Using the fact that sec(π/4) = √2, we have:

dy = sec^2(π/4) dx = (√2)^2 (-0.1) = 2 (-0.1) = -0.2.

Thus, evaluating dy for x = π/4 and dx = -0.1 yields dy = -0.2.

To find the slope of the tangent line to the polar curve r = 2sinθ at a specific point, we need to convert the polar equation to Cartesian coordinates and then calculate the derivative. After obtaining the derivative, we can evaluate it at the given point to determine the slope of the tangent line.

The polar equation r = 2sinθ can be converted to Cartesian coordinates using the equations x = rcosθ and y = rsinθ. Substituting the given equation into these formulas, we have x = 2sinθcosθ and y = 2sin²θ. Next, we can find the derivative dy/dx using implicit differentiation. Taking the derivative of y with respect to θ and x with respect to θ, we can write dy/dx = (dy/dθ) / (dx/dθ).

Differentiating x and y with respect to θ, we obtain dx/dθ = 2cos²θ - 2sin²θ and dy/dθ = 4sinθcosθ. Dividing dy/dθ by dx/dθ, we have dy/dx = (4sinθcosθ) / (2cos²θ - 2sin²θ). Now, we need to evaluate this expression at the given point.

(a)  Volume of the solid generated by rotating the region enclosed by = y² – 4y + 4 and +y= 4 when x = 4 is (1408/15)π cubic units.

To find the volume of the solid generated by rotating the region enclosed by the curve y² - 4y + 4 and x = 4 about the line x = 4, we can use the method of cylindrical shells.

The volume can be calculated using the formula:

V = ∫[a,b] 2πx f(x) dx,

where [a, b] is the interval of integration and f(x) represents the height of the shell at a given x-value.

In this case, the interval of integration is [0, 4], and the height of the shell, f(x), is given by f(x) = y² - 4y + 4.

To express the curve y² - 4y + 4 in terms of x, we need to solve for y:

y² - 4y + 4 = x

Completing the square, we get:

(y - 2)² = x

Taking the square root and solving for y, we have:

y = 2 ± √x

Since we want to find the volume within the interval [0, 4], we consider the positive square root:

y = 2 + √x

Therefore, the height of the shell, f(x), is:

f(x) = (2 + √x)² - 4(2 + √x) + 4

     = x + 4√x

Now we can calculate the volume:

V = ∫[0,4] 2πx (x + 4√x) dx

Integrating term by term:

V = 2π ∫[0,4] (x² + 4x√x) dx

Using the power rule of integration:

V = 2π [(1/3)x³ + (8/5)x^(5/2)] evaluated from 0 to 4

V = 2π [(1/3)(4)³ + (8/5)(4)^(5/2)] - 2π [(1/3)(0)³ + (8/5)(0)^(5/2)]

V = 2π [(1/3)(64) + (8/5)(32)] - 0

V = 2π [(64/3) + (256/5)]

V = 2π [(320/15) + (384/15)]

V = 2π (704/15)

V = (1408/15)π

Therefore, the volume of the solid generated by rotating the region enclosed by y² - 4y + 4 and x = 4 about the line x = 4 is (1408/15)π cubic units.

(b) Volume of the solid generated by rotating the region enclosed by : = y² – 4y + 4 and +y= 4 when y = 3 is 370π cubic units.

The volume can be calculated using the formula:

V = ∫[a,b] 2πx f(y) dy,

where [a, b] is the interval of integration and f(y) represents the height of the shell at a given y-value.

In this case, the interval of integration is [1, 4], and the height of the shell, f(y), is given by f(y) = y² - 4y + 4.

Now we can calculate the volume:

V = ∫[1,4] 2πx (y² - 4y + 4) dy

Integrating term by term:

V = 2π ∫[1,4] (xy² - 4xy + 4x) dy

Using the power rule of integration:

V = 2π [(1/3)xy³ - 2xy² + 4xy] evaluated from 1 to 4

V = 2π [(1/3)(4)(4)³ - 2(4)(4)² + 4(4)(4)] - 2π [(1/3)(1)(1)³ - 2(1)(1)² + 4(1)(1)]

V = 2π [(64/3) - 32 + 64] - 2π [(1/3) - 2 + 4]

V = 2π [(64/3) + 32] - 2π [(1/3) + 2 + 4]

V = 2π [(64/3) + 32 - (1/3) - 2 - 4]

V = 2π [(192/3) + 96 - 1 - 6]

V = 2π [(288/3) + 89]

V = 2π [(96) + 89]

V = 2π (185)

V = 370π

Therefore, the volume of the solid generated by rotating the region enclosed by y² - 4y + 4 about the line y = 3 is 370π cubic units.

Hence we can say that,

(a) The volume of the solid generated by rotating the region enclosed by y² - 4y + 4 and x = 4 about the line x = 4 is (1408/15)π cubic units.

(b) The volume of the solid generated by rotating the region enclosed by y² - 4y + 4 about the line y = 3 is 370π cubic units.
