The given function (t) = 6(e^(-0.01t) - 0.06) models the concentration of the antibiotic in the bloodstream after taking a tablet, where t represents time measured in hours and (t) represents the concentration measured in ug/mL.

1. Initial concentration: Substituting t = 0 into the function, we get:

  (0) = 6(e^(-0.01 * 0) - 0.06) = 6(1 - 0.06) = 6(0.94) ≈ 5.64 ug/mL.

  So, the initial concentration is approximately 5.64 ug/mL.

2. Limiting concentration: As t approaches infinity, the term e^(-0.01t) tends to zero, and we have:

  lim (t→∞) (t) = 6(0 - 0.06) = 6(-0.06) = -0.36 ug/mL.

  Therefore, the concentration approaches -0.36 ug/mL as time goes to infinity. Note that negative concentrations do not have physical meaning, so we can consider the limiting concentration to be effectively zero.

3. Behavior over time: The exponential term e^(-0.01t) decreases exponentially with time, causing the concentration to decrease as well. The term -0.06 acts as a downward shift, reducing the overall concentration values.

To find the approximation using the Trapezoidal Rule and Simpson's Rule, we need to divide the interval [2.0, 2.6] into subintervals and compute the corresponding approximations for each rule.

(a) Trapezoidal Rule (T3):

To approximate the integral using the Trapezoidal Rule with 3 subintervals (n = 3), we divide the interval [2.0, 2.6] into 3 equal subintervals:

Subinterval 1: [2.0, 2.2]

Subinterval 2: [2.2, 2.4]

Subinterval 3: [2.4, 2.6][tex]((x2 - x1) / 2) * (f(x1) + 2*f(x2) + f(x3))[/tex]

Using the Trapezoidal Rule formula for each subinterval, we have:

T3 = ((x2 - x1) / 2) * (f(x1) + 2*f(x2) + f(x3))

For Subinterval 1:

x1 = 2.0, x2 = 2.2, x3 = 2.4

f(x1) = 2.0, f(x2) = 2.3, f(x3) = 2.1

T1 = [tex]((2.2 - 2.0) / 2) * (2.0 + 2*2.3 + 2.1)[/tex]

x1 = 2.2, x2 = 2.4, x3 = 2.6

f(x1) = 2.3, f(x2) = 2.4, f(x3) = 2.6

T2 = ((2.4 - 2.2) / 2) * (2.3 + 2*2.4 + 2.6)

For Subinterval 3:

x1 = 2.4, x2 = 2.6, x3 = 2.6 (last point is repeated)

f(x1) = 2.4, f(x2) = 2.6, f(x3) = 2.6

T3 = ((2.6 - 2.4) / 2) * (2.4 + 2*2.6 + 2.6)

Now, we sum up the individual approximations:

T3 = T1 + T2 + T3

Calculate the values for each subinterval and then sum them up.

The instantaneous rate of change of g at the point (4, 1, 2) in the direction of the vector v = (1, 2) is -1/(√5) + 1/(3ln(3)√5).

To calculate the instantaneous rate of change of the function g(x, y) at the point (4, 1, 2) in the direction of the vector v = (1, 2), we need to find the directional derivative of g in that direction.

The directional derivative of a function f(x, y) in the direction of a vector v = (a, b) is given by the dot product of the gradient of f with the unit vector in the direction of v:

D_v(f) = ∇f · (u_v)

where ∇f is the gradient of f and u_v is the unit vector in the direction of v.

Let's calculate the gradient of g(x, y):

∇g = (∂g/∂x, ∂g/∂y)

Taking partial derivatives of g(x, y) with respect to x and y:

∂g/∂x = (∂/∂x)(cos(πI√y)) + (∂/∂x)(1 log3(x - y))

= 0 + 1/(x - y) log3(e)

∂g/∂y = (∂/∂y)(cos(πI√y)) + (∂/∂y)(1 log3(x - y))

= -πI sin(πI√y) + 0

The gradient of g(x, y) is:

∇g = (1/(x - y) log3(e), -πI sin(πI√y))

Now, let's calculate the unit vector u_v in the direction of v = (1, 2):

||v|| = sqrt(1^2 + 2^2) = sqrt(5)

u_v = v / ||v|| = (1/sqrt(5), 2/sqrt(5))

Next, we calculate the dot product of ∇g and u_v:

∇g · u_v = (1/(x - y) log3(e), -πI sin(πI√y)) · (1/sqrt(5), 2/sqrt(5))

     = (1/(x - y) log3(e))(1/sqrt(5)) + (-πI sin(πI√y))(2/sqrt(5))

Finally, substitute the given point (4, 1, 2) into the expression and calculate the instantaneous rate of change of g in the direction of v:

D_v(g) = ∇g · u_v evaluated at (x, y) = (4, 1, 2)

Please note that the value of πI√y depends on the value of y. Without knowing the exact value of y, it is not possible to calculate the precise instantaneous rate of change of g in the direction of v.

To find the average value of a function on an interval, we need to calculate the integral of the function over that interval and then divide it by the length of the interval.

In this case, the function is f(x) = 6x² and the interval is [0, 2].

To find the integral of f(x), we integrate 6x² with respect to x:

∫ 6x² dx = 2x³ + C

Next, we evaluate the integral over the interval [0, 2]:

∫[0,2] 6x² dx = [2x³ + C] from 0 to 2

= (2(2)³ + C) - (2(0)³ + C)

The solution for x in the given equation is x = -7/3. To solve for x in the given equation, let's go through the steps:

Step 1: Write down the equation

The equation is: (-2x + 1) - (x - 1) = 9

Step 2: Simplify the equation

Start by removing the parentheses using the distributive property. Distribute the negative sign to both terms inside the first set of parentheses:

-2x + 1 - (x - 1) = 9

Remove the parentheses around the second term:

-2x + 1 - x + 1 = 9

Combine like terms:

-3x + 2 = 9

Step 3: Isolate the variable term

To isolate the variable term (-3x), we need to get rid of the constant term (2). We can do this by subtracting 2 from both sides of the equation:

-3x + 2 - 2 = 9 - 2

This simplifies to:

-3x = 7

Step 4: Solve for x

To solve for x, divide both sides of the equation by -3:

(-3x)/-3 = 7/-3

This simplifies to:

x = -7/3

Therefore, the solution for x in the given equation is x = -7/3.

The triple integral evaluates to zero because the given solid R lies entirely within the plane z = 0, so the integral of z over that region is zero.

The given solid R is bounded by the paraboloid z = 1 – x^2 - y^2 and the plane z = 0. Cylindrical coordinates are well-suited to represent this solid. In cylindrical coordinates, the equation of the paraboloid becomes z = 1 - r^2, where r represents the radial distance from the z-axis. Since the solid lies entirely below the z = 0 plane, the limits of integration for z are 0 to 1 - r^2. The integral of z over the region will be zero because the limits of integration are symmetric around z = 0, resulting in equal positive and negative contributions that cancel each other out.

To find the maximum and minimum values of the function f(x) on the interval [0,4], we need to evaluate the function at critical points and endpoints within this interval.

First, we check the endpoints:

f(0) = (0 - 8(0)) / (0 + 2) = 0

f(4) = (4 - 8(4)) / (4 + 2) = -16/6 = -8/3

Next, we find the critical points by setting the derivative of f(x) equal to zero and solving for x:

f'(x) = [(1 - 8) * (x + 2) - (x - 8x)(1)] / (x + 2)^2 = 0

Simplifying, we get:

-7(x + 2) - x + 8x = 0

-7x - 14 - x + 8x = 0

0 = 0

Since 0 = 0 is an identity, there are no critical points within the interval [0,4].

Comparing the function values at the endpoints and noting that f(x) is a continuous function, we find:

The maximum value of f(x) on [0,4] is 0, which occurs at x = 0.

The minimum value of f(x) on [0,4] is -8/3, which occurs at x = 4.

In conclusion, the maximum value of the function f(x) = (x - 8x) / (x + 2) on the interval [0,4] is 0, and the minimum value is -8/3, occurring at x = 0 and x = 4, respectively.

The height of the water in the conical tank is changing at a rate of approximately 0.045 m/min when the height of the water is 7 m. As the height increases, the rate of change, dh/dt, decreases.

To find the rate at which the height of the water is changing, we can use the related rates approach.

The volume of cone is given by the formula V = (1/3) * π * r² * h, where V represents the volume, r is the radius of the base, and h is the height.

Since the base and height of the conical tank are equal, we can rewrite the formula as V = (1/3) * π * r² * h.

Given that the tank is being filled with water at a rate of 2 m³/min, we can express the rate of change of the volume with respect to time, dV/dt, as 2 m^3/min.

To find the rate at which the height is changing, we need to find dh/dt.

By differentiating the volume formula with respect to time, we get dV/dt = (1/3) * π *r² * (dh/dt). Solving for dh/dt, we find that dh/dt = (3 * dV/dt) / (π * r²).

Since we know that dV/dt = 2 m^3/min and the height of the water is 7 m, we can plug in these values to calculate dh/dt:

dh/dt = (3 * 2) / (π * r²)

      = 6 / (π * r²)

However, we are not given the radius of the base, so we cannot determine the exact value of dh/dt. Nonetheless, we can conclude that as the height increases, dh/dt decreases because the rate of change of the height is inversely proportional to the square of the radius.

(a) Using chain rule, we obtain; [tex]\(h'(2) = 576\)[/tex]

(b) Applying the power rule, we obtain; [tex]\(j'(0) = 1\)[/tex].

(a) To find [tex]\(h'(2)\) where \(h(x) = [g(x)]^3\)[/tex], we need to differentiate [tex]\(h(x)\)[/tex] with respect to [tex]\(x\)[/tex].

Given that [tex]\(g(x)\)[/tex] and [tex]\(g'(x)\)[/tex] are differentiable, we can use the chain rule.

The chain rule states that if we have a composite function [tex]\(h(x) = f(g(x))\)[/tex], then [tex]\(h'(x) = f'(g(x)) \cdot g'(x)\)[/tex].

In this case, [tex]\(h(x) = [g(x)]^3\)[/tex], so [tex]\(f(u) = u^3\)[/tex] where [tex]\(u = g(x)\).[/tex]

Taking the derivative of [tex]\(f(u) = u^3\)[/tex] with respect to [tex]\(u\)[/tex] gives [tex]\(f'(u) = 3u^2\)[/tex].

Applying the chain rule, we have [tex]\(h'(x) = f'(g(x)) \cdot g'(x) = 3[g(x)]^2 \cdot g'(x)\).[/tex]

Substituting [tex]\(x = 2\)[/tex], we get [tex]\(h'(2) = 3[g(2)]^2 \cdot g'(2)\).[/tex]

Using the given values in the table, [tex]\(g(2) = 8\) \\[/tex] and [tex]\(g'(2) = 3\)[/tex], so[tex]\(h'(2) = 3(8)^2 \cdot 3 = 3 \cdot 64 \cdot 3 = 576\)[/tex].

Therefore, [tex]\(h'(2) = 576\)[/tex].

(b) To find [tex]\(j'(0)\)[/tex] where [tex]\(j(x) = x + 2\)[/tex], we can differentiate [tex]\(j(x)\)\\[/tex] with respect to [tex]\(x\)[/tex] using the power rule.

The power rule states that if we have a function [tex]\(j(x) = x^n\), then \(j'(x) = n \cdot x^{n-1}\)[/tex].

In this case, [tex]\(j(x) = x + 2\)[/tex], which can be rewritten as [tex]\(j(x) = x^1 + 2\)\\[/tex].

Applying the power rule, we have [tex]\(j'(x) = 1 \cdot x^{1-1} = 1\)[/tex].

Therefore, [tex]\(j'(0) = 1\)\\[/tex].

The margin of error formula, E = Zα/2 * σ/√n, is used to estimate the confidence interval for the population mean μ. In the given conditions, we need to determine whether the formula can be applied based on the sample size and the knowledge of the population standard deviation σ.

11. For the condition where the sample size is n = 286 and σ = 15, the margin of error formula E = Zα/2 * σ/√n can be used. In this case, the sample size is relatively large (n > 30), which satisfies the condition for using the formula. Additionally, the population standard deviation σ is known. Therefore, the margin of error formula can be applied to estimate the confidence interval for the population mean μ.

12. In the condition where the sample size is n = 10 and σ is not known, the margin of error formula E = Zα/2 * σ/√n cannot be directly used. This is because the sample size is relatively small (n < 30), which violates the assumption of normality required for the formula to be valid. In situations where the population standard deviation σ is unknown and the sample size is small, the t-distribution should be used instead of the standard normal distribution. By using the t-distribution, a modified margin of error formula can be derived that accounts for the uncertainty in estimating the population standard deviation based on the sample.

The first limit is -8 and the second limit is 4.

For the first question, f(x) = -8x - 7, we need to find the limit as h approaches 0 of (f(4+h) - f(4))/h. Simplifying this expression gives us (-8(4+h) - 7 - (-8(4) - 7))/h. Simplifying further, we get (-8h)/h = -8.

Therefore, the limit as h approaches 0 of (f(4+h) - f(4))/h is -8.

For the second question, f(x) = x^2 + 7, we need to find the limit as h approaches 0 of (f(2+h) - f(2))/h. Substituting the values, we get ((2+h)^2 + 7 - (2^2 + 7))/h. Simplifying this expression gives us (4+4h+h^2+7-11)/h. Simplifying further, we get (h^2 + 4h)/h = h + 4.

Therefore, the limit as h approaches 0 of (f(2+h) - f(2))/h is 4.

In summary, the separable differential equations are (a) dy/dt = -3y and (c) dy/dt - 1 = t. The solutions for these equations are y = Ce^(-3t) and t = Ce^y + 1, respectively.

To determine which of the given differential equations are separable, we need to check if we can rewrite the equation in the form "dy/dt = g(t)h(y)", where g(t) and h(y) are functions of t and y, respectively.

(a) dy/dt = -3y:

This equation is separable since we can rewrite it as (1/y)dy = -3dt. By integrating both sides, we get ln|y| = -3t + C, where C is the constant of integration. Solving for y, we have y = Ce^(-3t).

(b) dy/dt - ty = -y:

This equation is not separable since the term "-ty" contains both t and y.

(c) dy/dt - 1 = t:

This equation is separable since we can rewrite it as (1/(t-1))dt = dy. By integrating both sides, we get ln|t-1| = y + C, where C is the constant of integration. Solving for t, we have t = Ce^y + 1.
