Calculate the area of rectangle K.

Rectangles H And K Are Similar.Calculate The Area Of Rectangle K.

Answers

Answer 1

Given that rectangles H and K are similar, and we have the dimensions of rectangle H , The area of rectangle K is approximately 225 square centimeters.

Let's denote the dimensions of rectangle K as Lk and Wk, representing its length and width, respectively.

Using the concept of similarity, we know that corresponding sides of similar rectangles are proportional. In this case, the ratio of the width of rectangle K (Wk) to the width of rectangle H (Wh) is equal to the ratio of the length of rectangle K (Lk) to the length of rectangle H (Lh).

We can set up the following proportion:

Wk / Wh = Lk / Lh

Substituting the given values:

Wk / 5cm = Lk / 8cm

Now, we can use the information provided to find the dimensions of rectangle K. It is given that the width of rectangle H is 5cm and the width of rectangle H is 15cm.

Solving for Wk in the proportion:

Wk / 5cm = 15cm / 8cm

Cross-multiplying and simplifying:

8Wk = 75cm

Wk = 75cm / 8

Wk ≈ 9.375cm

Now that we have the width of rectangle K, we can find the length using the same proportion:

Lk / 8cm = 15cm / 5cm

Cross-multiplying and simplifying:

5Lk = 8 * 15

Lk = 8 * 15 / 5

Lk = 24cm

Finally, we can calculate the area of rectangle K using the formula: Area = Length * Width.

Area of K = Lk * Wk

Area of K = 24cm * 9.375cm

Area of K ≈ 225 cm²

Therefore, the area of rectangle K is approximately 225 square centimeters.

Set up the integral (or integrals) needed to compute the net area. Select the correct choice below and fill in the answer boxes to complete your answer. OA. dx+ dx OB. [00* S dx -5

Answers

The answers to the questions are as follows:

(i) The net area is ∫[0, π/2] 9 cos x dx.

(ii) The area of the region above the x-axis bounded by y = 25 - x² is ∫[-5, 5] (25 - x²) dx.

How did we get these values?

To find the net area and the area of the region bounded by the curve and the x-axis, graph the function and determine the intervals of interest.

1) Graphing the function y = 9 cos x:

The graph of y = 9 cos x represents a cosine curve that oscillates between -9 and 9 along the y-axis. It is a periodic function with a period of 2π.

2) Determining the intervals of interest:

To find the net area and the area of the region, identify the x-values where the curve intersects the x-axis. In this case, given that cos x equals zero when x is an odd multiple of π/2.

The first interval of interest is between x = 0 and x = π/2, where the cosine curve goes from positive to negative and intersects the x-axis.

3) Computing the net area:

To find the net area, calculate the integral of the absolute value of the function over the interval [0, π/2]. The integral represents the area under the curve between the x-axis and the function.

The net area can be computed as:

Net Area = ∫[0, π/2] |9 cos x| dx

Since the absolute value of cos x is equivalent to cos x over the interval [0, π/2], simplify the integral to:

Net Area = ∫[0, π/2] 9 cos x dx

4) Setting up the integral:

The integral to compute the net area is given by:

Net Area = ∫[0, π/2] 9 cos x dx

Now, let's move on to the second question.

1) Graphing the function y = 25 - x²:

The graph of y = 25 - x² represents a downward-opening parabola with its vertex at (0, 25) and symmetric around the y-axis.

2) Determining the region of interest:

To find the area above the x-axis bounded by the curve, identify the x-values where the curve intersects the x-axis. In this case, the parabola intersects the x-axis when y equals zero.

Setting 25 - x² equal to zero and solving for x:

25 - x² = 0

x² = 25

x = ±5

The region of interest is between x = -5 and x = 5, where the parabola is above the x-axis.

3) Computing the area:

To find the area of the region above the x-axis, calculate the integral of the function over the interval [-5, 5].

The area can be computed as:

Area = ∫[-5, 5] (25 - x²) dx

4) Setting up the integral:

The integral to compute the area is given by:

Area = ∫[-5, 5] (25 - x²) dx

So, the answers to the questions are as follows:

(i) The net area is ∫[0, π/2] 9 cos x dx.

(ii) The area of the region above the x-axis bounded by y = 25 - x² is ∫[-5, 5] (25 - x²) dx.

Find the equation of the line tangent to 2ey = x + y at the point (2, 0). Write the equation in slope-intercept form, y=mx+b. Do not use the equation editor to answer. Write fractions in the form a/b.

Answers

To find the equation of the line tangent to the curve 2ey = x + y at the point (2, 0), we need to find the derivative of the curve and evaluate it at the given point.

First, we differentiate the equation 2ey = x + y with respect to x using the rules of calculus. Taking the derivative of ey with respect to x gives us ey(dy/dx) = 1 + dy/dx.

Simplifying the equation, we get dy/dx = (1 - ey)/(ey - 1).

Next, we substitute x = 2 and y = 0 into the derivative equation to find the slope of the tangent line at the point (2, 0). Plugging in these values gives us dy/dx = (1 - e0)/(e0 - 1) = 0.

Since the slope of the tangent line is 0, we know that the line is horizontal. Therefore, the equation of the tangent line in slope-intercept form is y = 0x + b, where b is the y-intercept.

Since the tangent line passes through the point (2, 0), we can substitute these coordinates into the equation to solve for the y-intercept. Thus, we have 0 = 0(2) + b, which gives us b = 0.

Therefore, the equation of the tangent line is y = 0x + 0, which simplifies to y = 0.

Answers

A parametrization for the line segment with endpoints (1,-5) and (4,-7) can be given by the equations x = t + 1 and y = -2t - 5, where t ranges from 0 to 3.

To find a parametrization for the given line segment, we can start by observing that the x-coordinates of the endpoints increase by 3 (from 1 to 4) and the y-coordinates decrease by 2 (from -5 to -7). We can represent this change as a linear function of t, where t ranges from 0 to 3.

Let's assume that t represents the parameter along the line segment. We can set up the following equations:

x = t + 1,

y = -2t - 5.

When t = 0, x = 0 + 1 = 1 and y = -2(0) - 5 = -5, which corresponds to the first endpoint (1,-5). When t = 3, x = 3 + 1 = 4 and y = -2(3) - 5 = -7, which corresponds to the second endpoint (4,-7).

Therefore, the parametrization for the line segment is given by x = t + 1 and y = -2t - 5, where t ranges from 0 to 3. This parametrization allows us to express any point along the line segment in terms of the parameter t.

Find the solution of the first order ODE
sinx Find the solution of the first order ODE tan (x) + x tau (x) e x with the initial value y (0) = 2 dy dx t x ty sin(x) = 0 2

Answers

The given first-order ordinary differential equation (ODE) is tan(x) + x * τ(x) * e^x = 0, and we need to find the solution with the initial value y(0) = 2. The solution to the ODE involves finding the antiderivative of the expression and then applying the initial condition to determine the constant of integration. The solution can be expressed as y(x) = 2 * cos(x) - x * e^(-x) * sin(x) - 1.

To solve the given ODE, we start by integrating both sides of the equation. The antiderivative of tan(x) with respect to x is -ln|cos(x)|, and the antiderivative of e^x is e^x. Integrating the expression, we obtain -ln|cos(x)| + x * τ(x) * e^x = C, where C is the constant of integration.

Next, we apply the initial condition y(0) = 2. Substituting x = 0 and y = 2 into the equation, we have -ln|cos(0)| + 0 * τ(0) * e^0 = C, which simplifies to -ln(1) + 0 = C. Hence, C = 0.

Finally, rearranging the equation -ln|cos(x)| + x * τ(x) * e^x = 0 and expressing τ(x) as τ(x) = -sin(x), we obtain -ln|cos(x)| + x * (-sin(x)) * e^x = 0. Simplifying further, we have ln|cos(x)| = x * e^(-x) * sin(x) - 1.

Therefore, the solution to the given first-order ODE with the initial value y(0) = 2 is y(x) = 2 * cos(x) - x * e^(-x) * sin(x) - 1.

The integral of Ssin(7x+5) dx is evaluated using the substitution method. The result is (10/21)cos(7x+5) + C, where C is the constant of integration.

To evaluate the integral ∫sin(7x+5) dx, we can use the substitution method.

Let's substitute u = 7x + 5. By differentiating both sides with respect to x, we get du/dx = 7, which implies du = 7 dx. Rearranging this equation, we have dx = (1/7) du.

Now, we can rewrite the integral using the substitution: ∫sin(u) (1/7) du. The (1/7) can be pulled out of the integral since it's a constant factor. Thus, we have (1/7) ∫sin(u) du.

The integral of sin(u) can be evaluated easily, giving us -cos(u) + C, where C is the constant of integration.

Replacing u with 7x + 5, we obtain -(1/7)cos(7x + 5) + C.

Finally, multiplying the (1/7) by (10/1) and simplifying, we get the result (10/21)cos(7x + 5) + C. This is the final answer to the given integral.

Use the substitution method to evaluate the definite integral. Remember to transform the limits of integration too. DO NOT go back to x in the process. Give the exact answer in simplest form. 3 S₁²

Answers

The definite integral of 3 S₁² using the substitution method with the limits of integration transformed is 3 / (4π).

To evaluate the definite integral of 3 S₁², we can use the substitution method with the substitution u = cos θ. This gives us du = -sin θ dθ, which we can use to transform the integral limits as well.

When θ = 0, u = cos 0 = 1. When θ = π, u = cos π = -1. So, the integral limits become:

∫[1, -1] 3 S₁² du

Next, we need to express S₁ in terms of u. Using the identity S₁² + S₂² = 1, we have:

S₁² = 1 - S₂²

= 1 - sin² θ

= 1 - (1 - cos² θ)

= cos² θ

Substituting u = cos θ, we get:

S₁² = cos² θ = u²

Therefore, our integral becomes:

∫[1, -1] 3 u² du

Integrating with respect to u and evaluating at the limits, we get:

∫[1, -1] 3 u² du = [u³]₋₁¹ = (1³ - (-1)³)3/3 = 2*3/3 = 2

Finally, we need to convert back to θ from u:

2 = ∫[1, -1] 3 S₁² du = ∫[0, π] 3 cos² θ sin θ dθ

Using the identity sin θ = d/dθ (-cos θ), we can simplify the integral:

2 = ∫[0, π] 3 cos² θ sin θ dθ

= ∫[0, π] 3 cos² θ (-d/dθ cos θ) dθ

= ∫[0, π] 3 (-cos³ θ + cos θ) dθ

= [sin θ - (1/3) sin³ θ]₋₀π

Find an equation of the ellipse with foci (3,2) and (3,-2) and
major axis of length 8

Answers

The equation of the ellipse is [tex](x - 3)^2 / 16 = 1[/tex]

How to o find the equation of the ellipse?

To find the equation of the ellipse with the given foci and major axis length, we need to determine the center and the lengths of the semi-major and semi-minor axes.

Given:

Foci: (3, 2) and (3, -2)

Major axis length: 8

The center of the ellipse is the midpoint between the foci. Since the x-coordinate of both foci is the same (3), the x-coordinate of the center will also be 3. To find the y-coordinate of the center, we take the average of the y-coordinates of the foci:

Center: (3, (2 + (-2))/2) = (3, 0)

The distance from the center to each focus is the semi-major axis length (a). Since the major axis length is 8, the semi-major axis length is a = 8/2 = 4.

The distance between each focus and the center is also related to the distance between the center and each vertex (the endpoints of the major axis). This distance is the semi-minor axis length (b).

The distance between the foci is given by 2c, where c is the distance from the center to each focus. In this case, 2c = 2(2) = 4. Since the center is at (3, 0), the vertices are located at (3 ± a, 0). Therefore, the distance between each focus and the center is b = 4 - 4 = 0.

We now have the center (h, k) = (3, 0), the semi-major axis length a = 4, and the semi-minor axis length b = 0.

The equation of an ellipse with its center at (h, k) is given by:

[tex]((x - h)^2 / a^2) + ((y - k)^2 / b^2)[/tex] = 1

Substituting the values, we have:

[tex]((x - 3)^2 / 4^2) + ((y - 0)^2 / 0^2)[/tex] = 1

Simplifying the equation, we get:

B = ______

Answers

The coefficient for the x-term on the left side is 0, therefore we can use it to find A and B in the equation 56 - (A + B)x + (A + B) = 0. The equation A + 8B = 0 is obtained by setting the constant terms on both sides equal. B is found by subtracting this equation from the first. This value of B solves either equation for A.

Let's start by looking at the equation 56 - (A + B)x + (A + B) = 0. Since there is no x-term on the left side, the coefficient for the x-term on the right side must equal 0. This gives us the equation A + B = 0.

Next, we have the equation A + 8B = 0, which is obtained by setting the constant term on the left side equal to the constant term on the right side. Now, we can subtract this equation from the previous one to eliminate A:

(A + B) - (A + 8B) = 0 - 0

Simplifying, we get:

-B - 7B = 0

-8B = 0

Dividing both sides of the equation by -8, we find that B = 0.

Substituting this value of B into either of the equations, we can solve for A. Let's use A + B = 0:

A + 0 = 0

A = 0

Therefore, the value of B is 0, and the value of A is also 0.

To find the net area covered by the function f(x) = (x + 1)² for the interval (-1,2], we must take the definite integral of the function on that interval.

To find the integral of the function, we must first expand it using the FOIL method, as follows:

f(x) = (x + 1)²f(x) = (x + 1)(x + 1)f(x) = x(x) + x(1) + 1(x) + 1(1)f(x) = x² + 2x + 1

Now that we have expanded the function, we can integrate it on the given interval as shown below:`∫(-1,2]f(x) dx = ∫(-1,2] (x² + 2x + 1) dx`

Evaluating the integral by using the power rule of integration gives:

∫(-1,2] (x² + 2x + 1) dx = [x³/3 + x² + x]

between -1 and 2`= [2³/3 + 2² + 2] - [(-1)³/3 + (-1)² - 1]`= [8/3 + 4 + 2] - [(-1/3) + 1 - 1]`= 14⅔

Answers

The derivative of the function f(y) = tan^(-1)(5y^5 + 4) is f'(y) = 25y^4 / (1 + (5y^5 + 4)^2).

To find the derivative of the function f(y) = tan^(-1)(5y^5 + 4), we can use the chain rule. Let's denote the inner function as u = 5y^5 + 4.

Applying the chain rule, we have:

f'(y) = d/dy [tan^(-1)(u)]

= (d/dy [u]) * (d/du [tan^(-1)(u)])

The derivative of u with respect to y is simply the derivative of 5y^5 + 4, which is 25y^4. The derivative of tan^(-1)(u) with respect to u is 1 / (1 + u^2).

Substituting these derivatives back into the chain rule formula, we get:

f'(y) = (25y^4) * (1 / (1 + (5y^5 + 4)^2))

= 25y^4 / (1 + (5y^5 + 4)^2)

Therefore, the derivative of f(y) is f'(y) = 25y^4 / (1 + (5y^5 + 4)^2).

Answers

The vector field F = (x*y, y) is not conservative.

To determine if the vector field  F = (x*y, y) is conservative, we can check if its curl is zero. The curl of a 2D vector field F = (P(x, y), Q(x, y)) is given by:
Curl(F) = (∂Q/∂x) - (∂P/∂y)

In our case, P(x, y) = x*y and Q(x, y) = y. So we need to compute the partial derivatives:
∂P/∂y = x
∂Q/∂x = 0

Now, we can compute the curl:
Curl(F) = (∂Q/∂x) - (∂P/∂y) = 0 - x = -x

Since the curl is not zero, we can state that the vector field F is not conservative.

Answers

The integral ∫ (7)/(x^(6)) dx converges by using the integral test and the limit value is 7/5. The series ∫ (3)/((4x+2)^3) dx is convergent and converges to 3/8.

To evaluate the given series and integral, let's start with the first problem:

Evaluating the series:

We have the series Σ (7)/(n^(6)) with n starting from 1 and going to infinity.

To determine if the series converges or diverges, we can use the Integral Test. The Integral Test states that if f(x) is a positive, continuous, and decreasing function on the interval [1, infinity), then the series Σ f(n) converges if and only if the improper integral ∫[1, infinity] f(x) dx converges.

In this case, f(x) = (7)/(x^(6)). Let's evaluate the improper integral:

∫ (7)/(x^(6)) dx = -[(7)/(5x^(5))] + C

Evaluating this integral from 1 to infinity:

lim[x->∞] [-[(7)/(5x^(5))] + C] - [-[(7)/(5(1)^(5))] + C]

= [-[(7)/(5(∞)^(5))] + C] - [-[(7)/(5(1)^(5))] + C]

= [-[(7)/(5(∞)^(5))]] + [(7)/(5(1)^(5))]

= 0 + 7/5

= 7/5

Since the integral ∫ (7)/(x^(6)) dx converges to a finite value of 7/5, the series Σ (7)/(n^(6)) also converges.

Now, let's move on to the second problem:

Evaluating the integral:

We have the integral ∫ (3)/((4x+2)^3) dx from 1 to infinity.

To evaluate this integral, we can use the substitution method. Let's substitute u = 4x + 2, then du = 4dx. Solving for dx, we have dx = (1/4)du. Substituting these values into the integral:

∫ (3)/((4x+2)^3) dx = ∫ (3)/(u^3) * (1/4) du

= (3/4) ∫ (1)/(u^3) du

= (3/4) * (-1/2u^2) + C

= -(3/8u^2) + C

Now we need to evaluate this integral from 1 to infinity:

lim[u->∞] [-(3/8u^2) + C] - [-(3/8(1)^2) + C]

= [-(3/8(∞)^2) + C] - [-(3/8(1)^2) + C]

= [-(3/8(∞)^2)] + [(3/8(1)^2)]

= 0 + 3/8

= 3/8

Therefore, the value of the integral ∫ (3)/((4x+2)^3) dx from 1 to infinity is 3/8.

Answers

The derivative of the given function f(x) = 2x + 16 is f'(x) = 2.

To find the value(s) of x where f'(x) = 0, we set f'(x) equal to zero and solve for x:

2 = 0

Since the equation 2 = 0 has no solution, there are no values of x where f'(x) = 0 for the given function f(x) = 2x + 16.

The derivative f'(x) represents the rate of change of the function f(x). In this case, the derivative is a constant value of 2, indicating that the function f(x) = 2x + 16 has a constant slope of 2. Therefore, there are no critical points or turning points where the derivative equals zero.

In conclusion, there are no values of x where f'(x) = 0 for the function f(x) = 2x + 16. The derivative f'(x) is a constant value of 2, indicating a constant slope throughout the function.

Answers

The recursive formula for the predicted number of speeding tickets issued each year in Middletown, starting from 2012 with an initial count of 190 tickets and growing by 10% each year, can be written as follows: N(year) = 1.1 * N(year - 1).

The recursive formula for the predicted number of speeding tickets each year is based on the assumption of exponential growth, where the number of tickets issued increases by 10% each year.

Let's denote N(year) as the predicted number of speeding tickets during a particular year. According to the given information, in the year 2012, Middletown issued 190 speeding tickets, which serves as our initial count or base case.

To calculate the number of tickets in subsequent years, we multiply the previous year's count by 1.1, representing a 10% increase. Therefore, the recursive formula for the predicted number of speeding tickets is:

N(year) = 1.1 * N(year - 1).

Using this formula, we can determine the predicted number of speeding tickets for any given year by recursively applying the growth rate of 10% to the previous year's count.

Answers

To evaluate the triple integral of x^2e^y dV over the region E bounded by the parabolic cylinder z=1-y^2 and the planes z=0, x=1, and x=-1, we can use the concept of iterated integrals.

In this case, the given region E is a bounded space between the parabolic cylinder and the specified planes. We can express this region in terms of the variable limits for the triple integral.

To start, we can set up the integral using the appropriate limits of integration. Since E is bounded by the planes x=1 and x=-1, we can integrate with respect to x from -1 to 1. For each x-value, the limits for y can be determined by the parabolic cylinder, which gives us the range of y values as -√(1-x^2) to √(1-x^2). Finally, the limits for z are from 0 to 1-y^2.

By evaluating the triple integral with the given integrand and the specified limits of integration, we can calculate the numerical value of the integral. This approach allows us to find the volume or other quantities within the region defined by the boundaries of integration.

Answers

the evaluation of the integral is (7/3)x^3 + (7/2)x^2 + 11e^(-x^6) + C,where C is the constant of integration

We have three terms in the integral: 7x^2, 7x, and 11e^(-x^6).For the term 7x^2, we can apply the power rule for integration, which states that the integral of x^n with respect to x is (1/(n+1))x^(n+1). Applying this rule, we have (7/3)x^3.For the term 7x, we can again apply the power rule, considering x as x^1. The integral of x with respect to x is (1/2)x^2. Thus, the integral of 7x is (7/2)x^2.

For the term 11e^(-x^6), we can directly integrate it using the rule for integrating exponential functions. The integral of e^u with respect to u is e^u. In this case, u = -x^6, so the integral of 11e^(-x^6) is 11e^(-x^6).Putting all the results together, the integral becomes (7/3)x^3 + (7/2)x^2 + 11e^(-x^6) + C, where C is the constant of integration.

Question 9 1 pts If $20,000 is invested in a savings account offering 3.5% per year, compounded semiannually, how fast is the balance growing after 5 years? Round answer to 2-decimal places.

Answers

The balance is not growing after 5 years. The growth rate is 0.  Let's recalculate the growth rate of the balance after 5 years in the given savings account.

To calculate the growth rate of the balance after 5 years in a savings account, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the final amount (balance)

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

t = the number of years

In this case, P = $20,000, r = 3.5% = 0.035 (as a decimal), n = 2 (compounded semiannually), and t = 5.

Plugging these values into the formula, we have:

A = $20,000(1 + 0.035/2)^(2*5)

A = $20,000(1.0175)^10

Using a calculator, we can find the value of (1.0175)^10 and denote it as (1.0175)^10 = R.

A = $20,000 * R

To find the growth rate, we need to calculate the derivative of A with respect to t:

dA/dt = P * (ln(R)) * dR/dt

dR/dt represents the rate at which (1.0175)^10 changes with respect to time. Since the interest rate is fixed, dR/dt is zero, and the derivative simplifies to:

dA/dt = P * (ln(R)) * 0

dA/dt = 0

Find a vector that points in a direction of no change in the function at P. THE a. What is the unit vector in the direction of steepest ascent at P?

Answers

The  unit vector in the direction of steepest ascent at point   [tex]P(-1, 1)[/tex] is [tex](-2 \sqrt{13} / 13, 3\sqrt{13} / 13)[/tex].

Given function is  [tex]f(x,y)= 3x^4-4x^2y + y^2 +7[/tex].

The unit vector in the direction of steepest ascent at point P can be found by taking the gradient of the function [tex]f(x, y)[/tex] and normalizing it. The gradient of [tex]f(x, y)[/tex]  is a vector that points in the direction of the steepest ascent, and normalizing it yields a unit vector in that direction.

To find the gradient, we need to compute the partial derivatives of f(x, y) with respect to x and y. Calculate them:

∂f/∂x = [tex]12x^3 - 8xy[/tex]

∂f/∂y = [tex]-4x^2 + 2y[/tex]

Evaluating these partial derivatives at the point P(-1, 1), we have:

∂f/∂x = [tex]12(-1)^3 - 8(-1)(1) = -4[/tex]

∂f/∂y = [tex]-4(-1)^2 + 2(1) = 6[/tex]

Construct the gradient vector by combining these partial derivatives:

∇f(x, y) = [tex](-4, 6)[/tex]

To obtain the unit vector in the direction of steepest ascent at point P, we normalize the gradient vector:

u = ∇f(x, y) / ||∇f(x, y)||

Where ||∇f(x, y)|| denotes the magnitude of the gradient vector.

Calculating the magnitude of the gradient vector:

||∇f(x, y)|| = [tex]\sqrt{((-4)^2 + 6^2)}[/tex]

||∇f(x, y)|| = [tex]\sqrt{52}[/tex]

||∇f(x, y)|| = [tex]2\sqrt{13}[/tex]

Dividing the gradient vector by its magnitude, obtain the unit vector:

u = [tex](-4 / 2\sqrt{13} , 6 / 2\sqrt{13} )[/tex]

u =[tex](-2 / \sqrt{13} , 3 / \sqrt{13} )[/tex]

u  =  [tex](-2 \sqrt{13} / 13, 3\sqrt{13} / 13)[/tex].

Therefore, the unit vector in the direction of steepest ascent at point   [tex]P(-1, 1)[/tex] is [tex](-2 \sqrt{13} / 13, 3\sqrt{13} / 13)[/tex].

To find the equation for elasticity, we need to calculate the derivative of the demand function, D(p), with respect to p. Let's go through the steps:

D(p) = 120 - 10p

a) Find the derivative of D(p) with respect to p:

D'(p) = -10

b) Find the value of p when D'(p) = -10:

D'(p) = -10

-10 = -10p

p = 1

c) Plug the value of p into the demand function D(p) to find the corresponding quantity x:

D(p) = 120 - 10p

D(1) = 120 - 10(1)

D(1) = 110

So, when the price is $1, the quantity demanded is 110.

d) Substitute the values of D(1), D'(1), and p = 1 into the elasticity equation:

E(p) = D(p) * p / D'(p)

E(1) = D(1) * 1 / D'(1)

E(1) = 110 * 1 / -10

E(1) = -11

False. Not every autonomous differential equation is a separable differential equation.

A separable differential equation is a type of differential equation that can be written in the form dy/dx = f(x)g(y), where f(x) and g(y) are functions of x and y, respectively. In a separable differential equation, the variables x and y can be separated and integrated separately.

On the other hand, an autonomous differential equation is a type of differential equation where the derivative is expressed solely in terms of the dependent variable. In other words, the equation does not explicitly depend on the independent variable.

While some autonomous differential equations may be separable, it is not true that every autonomous differential equation can be expressed as a separable differential equation.

Autonomous differential equations can take various forms, and not all of them can be transformed into the separable form.

Answers

The approximate value of the integral is -9.0167.

To approximate the value of the given integral using the trapezoidal rule with n = 10, we divide the interval [5, 9] into 10 subintervals and apply the formula for the trapezoidal rule.

The trapezoidal rule states that the integral of a function f(x) over an interval [a, b] can be approximated as follows:

∫[a to b] f(x) dx ≈ (b - a) * [f(a) + f(b)] / 2

In this case, the integral we need to approximate is:

∫[5 to 9] (2x + x²) dx

We divide the interval [5, 9] into 10 subintervals of equal width:

Subinterval 1: [5, 5.4]

Subinterval 2: [5.4, 5.8]

...

Subinterval 10: [8.6, 9]

The width of each subinterval is h = (9 - 5) / 10 = 0.4

Now we calculate the approximation using the trapezoidal rule:

Approximation = h * [f(a) + 2(f(x1) + f(x2) + ... + f(xn-1)) + f(b)]

For each subinterval, we evaluate the function at both endpoints and sum the values.

Finally, we sum the approximations for each subinterval to obtain the approximate value of the integral. In this case, the approximate value is -9.0167 (rounded to four decimal places).
