Let f(x) = 1+x² . Find the average slope value of f(x) on the interval [0,2]. Then using the Mean Value Theorem, find a number c in [0,2] so that f '(c) = the average slope value.

Answers

Answer 1

The average slope value of f(x) on the interval [0,2] is c =  4/3 then by using the Mean Value Theorem, c= 2/3.

f(x) = 1 + x²

Here, we have to find the average slope value of f(x) on the interval [0,2] and then using the Mean Value Theorem, find a number c in [0,2] so that f'(c) = the average slope value.

To find the average slope value of f(x) on the interval [0,2], we use the formula:

(f(b) - f(a))/(b - a)

where, a = 0 and b = 2

Hence, the average slope value of f(x) on the interval [0,2] is 4/3.

To find the number c in [0,2] so that f'(c) = the average slope value, we use the Mean Value Theorem which states that if a function f(x) is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a number c in (a,b) such that:f'(c) = (f(b) - f(a))/(b - a)

Here, a = 0, b = 2, f(x) = 1 + x² and the average slope value of f(x) on the interval [0,2] is 4/3.

Substituting these values in the formula above, we get:f'(c) = (4/3)

Simplifying this, we get:2c = 4/3c = 2/3

Therefore, c = 2/3 is the required number in [0,2] such that f'(c) = the average slope value.

Find the flux of the vector field F = (y; – 2, 2) across the part of the plane z = 1+ 4x + 3y above the rectangle (0, 3) x (0,4) with upwards orientation

Answers

The flux of the vector field F = (y, -2, 2) across the part of the plane

z = 1+ 4x + 3y above the rectangle (0, 3) x (0,4) with upwards orientation is 96 Wb.

To find the flux of the vector field F = (y, -2, 2) across the given surface, we can use the surface integral formula. The flux (Φ) of a vector field across a surface S is given by:

Φ = ∬S F · dS

where F is the vector field, dS is the outward-pointing vector normal to the surface, and the double integral is taken over the surface S.

In this case, the surface S is the part of the plane z = 1 + 4x + 3y above the rectangle (0, 3) × (0, 4).

Let's parameterize the surface S. Let's introduce two parameters u and v to represent the coordinates on the rectangle. We can define the position vector r(u, v) = ( x(u, v), y(u, v), z(u, v) ) as follows:

x(u, v) = u

y(u, v) = v

z(u, v) = 1 + 4u + 3v

Next, we calculate the partial derivatives of r(u, v) with respect to u and v:

∂r/∂u = (1, 0, 4)

∂r/∂v = (0, 1, 3)

Now, we can calculate the cross product of the partial derivatives:

∂r/∂u × ∂r/∂v = (-4, -3, 1)

The magnitude of this cross product is the area of the parallelogram defined by ∂r/∂u and ∂r/∂v, which is √((-4)^2 + (-3)^2 + 1^2) = √26.

To find the flux Φ, we integrate the dot product of F and the outward-pointing vector dS over the surface S:

Φ = ∬S F · dS = ∬S (y, -2, 2) · (∂r/∂u × ∂r/∂v) du dv

Since the outward-pointing vector is ∂r/∂u × ∂r/∂v = (-4, -3, 1), we have:

Φ = ∬S (y, -2, 2) · (-4, -3, 1) du dv

  = ∬S (-4y + 6 + 2) du dv

  = ∬S (-4y + 8) du dv

The limits of integration are u = 0 to 3 and v = 0 to 4, representing the rectangle (0, 3) × (0, 4). Therefore, the integral becomes:

Φ = ∫₀³ ∫₀⁴ (-4y + 8) dv du

Now, let's evaluate the integral:

Φ = ∫₀³ ∫₀⁴ (-4y + 8) dv du

  = ∫₀³ [-4yv + 8v]₀⁴ du

  = ∫₀³ (-16y + 32) du

  = [-16yu + 32u]₀³

  = -48y + 96

Finally, we substitute the limits of integration for y:

Φ = -48y + 96 = -48 *4  + 96 = -192 + 96 = -96

Thus, the required flux is 96 Wb

the covariance of two variables has been calculated to be −150. what does the statistic tell you about the two variables?

Answers

The statistic, which is the covariance of two variables, being calculated as -150 indicates that there is a negative linear relationship between the two variables.

Covariance measures the direction and strength of the linear relationship between two variables. A positive covariance indicates a positive linear relationship, while a negative covariance indicates a negative linear relationship. The magnitude of the covariance indicates the strength of the relationship. In this case, a covariance of -150 suggests a moderately strong negative linear relationship between the variables.

A negative covariance implies that as one variable increases, the other variable tends to decrease. In other words, the variables move in opposite directions. The magnitude of the covariance (-150) suggests that the relationship between the variables is relatively strong.

However, it is important to note that covariance alone does not provide information about the exact nature or strength of the relationship. Further analysis and interpretation, such as calculating the correlation coefficient, are needed to fully understand the relationship between the two variables.

Gas is escaping at a spherical balloon at a rate of 2 in^2/min. How fast is the surface changing when the radius is 12 inch?

Answers

The surface area of the balloon is changing at a rate of 192π square inches per minute when the radius is 12 inches. In other words, it is changing at a rate of 0.0053 in/min.

To find how fast the surface area is changing with respect to time, we need to use the formula for the surface area of a sphere.

The formula for the surface area (A) of a sphere with radius (r) is given by:

A = 4πr^2.

Given that the rate of change of the radius (dr/dt) is 2 in/min, we want to find the rate of change of the surface area (dA/dt) when the radius is 12 inches.

Differentiating the equation for the surface area with respect to time, we have:

dA/dt = d(4πr^2)/dt.

Using the power rule of differentiation, we get:

dA/dt = 8πr(dr/dt).

Substituting the given values, when r = 12 inches and dr/dt = 2 in/min, we have:

dA/dt = 8π(12)(2) = 192π in^2/min.

Find the order 3 Taylor polynomial T3(x) of the given function at f(x) = (3x + 16) T3(x) = -0. Use exact values.

Answers

The order 3 Taylor polynomial for the function \(f(x) = 3x + 16\) is given by T3(x)=16+3x using exact values.

To find the order 3 Taylor polynomial \(T_3(x)\) for the function \(f(x) = 3x + 16\), we need to calculate the function's derivatives up to the third order and evaluate them at the center \(c = 0\). The formula for the Taylor polynomial is:

\[T_3(x) = f(0) + f'(0)x + \frac{f''(0)}{2!}x^2 + \frac{f'''(0)}{3!}x^3\]

Let's find the derivatives of \(f(x)\):

\[f'(x) = 3\]

\[f''(x) = 0\]

\[f'''(x) = 0\]

Now, let's evaluate these derivatives at \(x = 0\):

\[f(0) = 3(0) + 16 = 16\]

\[f'(0) = 3\]

\[f''(0) = 0\]

\[f'''(0) = 0\]

Substituting these values into the formula for the Taylor polynomial, we get:

\[T_3(x) = 16 + 3x + \frac{0}{2!}x^2 + \frac{0}{3!}x^3\]

Simplifying further:

\[T_3(x) = 16 + 3x\]

use the limit comparison test to determine whether the series ∑n=8[infinity]7n 4n(n−7)(n−4) converges or diverges.

Answers

The limit is infinity, the series ∑n=8 to infinity (7n 4n(n−7)(n−4)) also diverges, because it grows at least as fast as the harmonic series. Therefore, the given series diverges.

To apply the limit comparison test, we need to choose a known series with positive terms that either converges or diverges. Let's choose the harmonic series as the comparison series, which is given by:

∑(1/n) from n = 1 to infinity

First, we need to show that the terms of the given series are positive for all n ≥ 8:

7n 4n(n−7)(n−4) > 0 for all n ≥ 8

The numerator (7n) and denominator (4n(n−7)(n−4)) are both positive for n ≥ 8, so the terms of the series are positive.

Next, let's find the limit of the ratio of the terms of the given series to the terms of the comparison series:

lim(n→∞) [(7n 4n(n−7)(n−4)) / (1/n)]

To simplify this limit, we can multiply both the numerator and denominator by n:

lim(n→∞) [(7n² 4(n−7)(n−4)) / 1]

Now, let's expand and simplify the numerator:

7n² - 4(n² - 11n + 28)

= 7n² - 4n² + 44n - 112

= 3n² + 44n - 112

Taking the limit as n approaches infinity:

lim(n→∞) [(3n² + 44n - 112) / 1]

= ∞

Analyzing the derivative further, we observe that it is positive in the intervals (-∞, -2) and (2, ∞), indicating an increasing function, and negative in the interval (-2, 2), suggesting a decreasing function.

The relative minimum occurs at (-2, 66), and the relative maximum at (2, -66).

There are no inflection points in the equation, and the concave is upward for the entire graph.

The critical points of a function are the points where the derivative is either zero or undefined.

In this case, we found the critical points by setting the derivative of the equation equal to zero. The interval of increase represents the x-values where the function is increasing, while the interval of decrease represents the x-values where the function is decreasing.

The relative minimum and maximum are the lowest and highest points on the graph, respectively, within a specific interval. Inflection points occur where the concavity of the graph changes, but in this equation, no such points exist. The concave being upward means that the graph curves in a U-shape.

Understanding these characteristics helps us analyze the behavior of the equation and its graphical representation.

A car leaves an intersection traveling west. Its position 5 sec later is 30 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position t sec later is y = t + 4t ft from the intersection. If the speed of the first car 5 sec after leaving the intersection is 11 ft/sec, find the rate at which the distance between the two cars is changing at that instant of time. (Round your answer to two decimal places.) ---Select---

Answers

The rate at which the distance between the two cars is changing at the instant when the first car's speed is 11 ft/sec, 5 seconds after leaving the intersection, is 9 ft/sec.

Let's denote the distance between the first car and the intersection as x and the distance between the second car and the intersection as y. We are given that at time t, y = t + 4t ft.

At the instant when the first car's speed is 11 ft/sec, 5 seconds after leaving the intersection, we have x = 30 ft and y = 11 × 5 = 55 ft.

The distance between the two cars, D, is given by the Pythagorean theorem: D = √(x² + y²).

Taking the derivative of D with respect to time, we get dD/dt = (dD/dx) × (dx/dt) + (dD/dy) × (dy/dt).

Since dx/dt represents the speed of the first car, which is constant at 11 ft/sec, and dy/dt represents the rate at which the second car's position changes, which is 1 + 4 = 5 ft/sec, the equation simplifies to dD/dt = (dD/dx) × 11 + (dD/dy) × 5.

To find dD/dt, we differentiate D = √(x² + y²) with respect to x and y, respectively. By substituting the values x = 30 and y = 55, we find dD/dt = (30/√305) × 11 + (55/√305) × 5 ≈ 9 ft/sec. Therefore, the rate at which the distance between the two cars is changing at that instant of time is approximately 9 ft/sec.

Answers

To evaluate the work done by the force field F = (2xy² + 3xz², 2x²y + 2y, 3x²z), we need to compute the line integral of F along the path C from (0,1,0) to (2,3,2).

The line integral of a vector field F along a curve C is given by the formula:

∫ F · dr = ∫ (F₁dx + F₂dy + F₃dz),

where dr is the differential vector along the curve C.

Parametrize the curve C as r(t) = (2t, 1+t, 2t), where t ranges from 0 to 1. Taking the derivatives, we find dr = (2dt, dt, 2dt).

Substituting these values into the line integral formula, we have:

∫ F · dr = ∫ ((2xy² + 3xz²)dx + (2x²y + 2y)dy + (3x²z)dz)

          = ∫ (4ty² + 6tz² + 2(1+t)dt + 6t²zdt + 6t²dt)

          = ∫ (4ty² + 6tz² + 2 + 2t + 6t²z + 6t²)dt

          = ∫ (6t² + 4ty² + 6tz² + 2 + 2t + 6t²z)dt.

Integrating term by term, we get:

∫ (6t² + 4ty² + 6tz² + 2 + 2t + 6t²z)dt = 2t³ + (4/3)ty³ + 2tz² + 2t² + t²z + 2t³z.

Evaluating this expression from t = 0 to t = 1, we find:

∫ F · dr = 2(1)³ + (4/3)(1)(1)³ + 2(1)(2)² + 2(1)² + (1)²(2) + 2(1)³(2)

          = 2 + (4/3) + 8 + 2 + 2 + 16

          = 30/3 + 16

          = 10 + 16

          = 26.

Therefore, the work done by the force field F in moving the object along the path C is 26 units.

Write the 9th term of the binomial expansion (3x – 2y) 12

Answers

The 9th term of the binomial expansion of (3x - 2y) raised to the power of 12 can be determined using the formula for the general term in the expansion.

The binomial expansion of (3x - 2y) raised to the power of 12 can be written as: (3x - 2y)^12 = C(12, 0)(3x)^12(-2y)^0 + C(12, 1)(3x)^11(-2y)^1 + ... + C(12, 9)(3x)^3(-2y)^9 + ... + C(12, 12)(3x)^0(-2y)^12. To find the 9th term, we need to focus on the term C(12, 9)(3x)^3(-2y)^9. Using the binomial coefficient formula, C(12, 9) = 12! / (9!(12-9)!) = 220. Therefore, the 9th term of the binomial expansion is 220(3x)^3(-2y)^9, which can be simplified to -220(27x^3)(512y^9) = -2,786,560x^3y^9.

Answers

a. The vector from (2, -7, 0) to (1, -3, -5)  is (-1, 4, -5).

b.  The vector from (1, -3, -5) to (2, -7, 0) is (1, -4, 5).

c. The position vector for (-90, 4) is (-90, 4).

(a) The vector from (2, -7, 0) to (1, -3, -5):

To find the vector between two points, we subtract the coordinates of the initial point from the coordinates of the final point. Therefore, the vector can be calculated as follows:

(1 - 2, -3 - (-7), -5 - 0) = (-1, 4, -5)

So, the vector from (2, -7, 0) to (1, -3, -5) is (-1, 4, -5).

(b) The vector from (1, -3, -5) to (2, -7, 0):

Similarly, we subtract the coordinates of the initial point from the coordinates of the final point to find the vector:

(2 - 1, -7 - (-3), 0 - (-5)) = (1, -4, 5)

Therefore, the vector from (1, -3, -5) to (2, -7, 0) is (1, -4, 5).

(c) The position vector for (-90, 4):

The position vector describes the vector from the origin (0, 0, 0) to a specific point. In this case, the position vector for (-90, 4) can be found as follows:

(-90, 4) - (0, 0) = (-90, 4)

Thus, the position vector for (-90, 4) is (-90, 4). This vector represents the displacement from the origin to the point (-90, 4) and can be used to describe the location or direction from the origin to that specific point in space.

therefore, her gross annual income is €69950

Hopefully this helps those that got stuck like me! <3

Answers

Naya's gross annual income is approximately $46,416.67.

To determine Naya's gross annual income, we need to reverse engineer the tax calculation based on the given information.

Let's denote Naya's gross annual income as G. We know that Naya's net annual income, after income tax, is 36,560. We also know that Naya pays income tax at the same rates and has the same annual tax credits as Emma.

Emma pays income tax on her taxable income at a rate of 20% on the first 35,300 and 40% on the balance. She has annual tax credits of 1,650.

Based on this information, we can set up the following equation:

G - (0.2 * 35,300) - (0.4 * (G - 35,300)) = 36,560 - 1,650

Let's solve this equation step by step:

G - 7,060 - 0.4G + 14,120 = 34,910

Combining like terms, we have:

0.6G + 7,060 = 34,910

Subtracting 7,060 from both sides:

0.6G = 27,850

Dividing both sides by 0.6:

G = 27,850 / 0.6

G ≈ 46,416.67

Therefore, Naya's gross annual income is approximately $46,416.67.

Answers

1. Using Newton's method, the only critical number of the function f(x) = ln(1 + x - x^2 + x^3) is approximately 0.789813.

2. The equation of the line passing through the point (3,5) that cuts off the least area from the first quadrant is y = -(5/3)x + 20/3.

3. The function f(x) = sin(x^2) - 137x + 231 is the function that passes through the point (137, 0) and has a derivative function of f'(x) = 12x cos(x^2).

To find the critical number of the function f(x) = ln(1 + x - x^2 + x^3), we can apply Newton's method.

The derivative of f(x) is given by f'(x) = (1 - 2x + 3x^2) / (1 + x - x^2 + x^3). By iteratively applying Newton's method with an initial guess, we can approximate the critical number. The process continues until we reach the desired level of accuracy. In this case, the critical number is approximately 0.789813.

To find the line passing through the point (3,5) that cuts off the least area from the first quadrant, we need to minimize the area of the triangle formed by the line, the x-axis, and the y-axis.

The equation of a line passing through (3,5) can be written as y = mx + c, where m represents the slope and c is the y-intercept. By minimizing the area of the triangle, we minimize the product of the base and height.

This occurs when the line is perpendicular to the x-axis, resulting in the least area. Therefore, the line equation is y = -(5/3)x + 20/3.

To find the function f(x) that passes through the point (137, 0) and has a derivative function of f'(x) = 12x cos(x^2), we integrate the derivative function with respect to x.

Integrating f'(x) gives us f(x) = sin(x^2) - 137x + C, where C is the constant of integration. To determine the value of C, we substitute the given point (137, 0) into the equation. This gives us 0 = sin(137^2) - 137(137) + C, which allows us to solve for C. The resulting function is f(x) = sin(x^2) - 137x + 231.

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes.

To estimate the volume V obtained by rotating the region under the curve y = √(3 + 20x) from x = 1 to x = 3 about the y-axis using the Midpoint Rule, we can follow these steps:

1. Divide the interval [1, 3] into subintervals of equal width.

  Let's choose n subintervals.

2. Calculate the width of each subinterval.

  Δx = (b - a) / n = (3 - 1) / n = 2 / n

3. Determine the midpoint of each subinterval.

  The midpoint of each subinterval can be calculated as:

  x_i = a + (i - 0.5)Δx, where i = 1, 2, 3, ..., n

4. Evaluate the function at each midpoint to get the corresponding heights.

  For each midpoint x_i, calculate y_i = √(3 + 20x_i).

5. Calculate the volume of each cylindrical shell.

  The volume of each cylindrical shell is given by:

  ΔV_i = 2πy_iΔx, where Δx is the width of the subinterval.

6. Sum up the volumes of all cylindrical shells to get the estimated total volume.

  V ≈ Σ ΔV_i from i = 1 to n

To obtain a more accurate estimate, you can choose a larger value of n.

Hence, the volume V obtained by rotating the region under the curve y = √(3 + 20x) from x = 1 to x = 3 about the y-axis using the Midpoint Rule

3. Determine the derivative of f(x) from First Principles. f(x)= 8x3 - Vex+T a bx+c

Answers

The derivative of f(x) = 8x³ - Vex + T + abx + c, found using first principles, is f'(x) = 24²2 + ab. This derivative represents the rate of change of the function with respect to x.

To find the derivative of the function f(x) = 8x³ - Vex + T + abx + c using first principles, we need to apply the definition of the derivative:

f'(x) = lim(h->0) [f(x+h) - f(x)] / h

Let's calculate it step by step

Replace f(x) with the given function:

f'(x) = lim(h->0) [(8(x+h)³ - Vex+h + T + ab(x+h) + c) - (8x³ - Vex + T + abx + c)] / h

Expand and simplify:

f'(x) = lim(h->0) [8(x³ + 3x²h + 3xh² + h³) - Vex+h + T + abx + abh + c - 8x^3 + Vex - T - abx - c] / h

Cancel out common terms:

f'(x) = lim(h->0) [8(3x²h + 3xh² + h³) + abh] / h

Distribute 8 into the terms inside the parentheses:

f'(x) = lim(h->0) [24x²h + 24xh² + 8h³ + abh] / h

Simplify and factor out h

f'(x) = lim(h->0) [h(24x² + 24xh + 8h² + ab)] / h

Cancel out h:

f'(x) = lim(h->0) 24x² + 24xh + 8h² + ab

Take the limit as h approaches 0:

f'(x) = 24x² + ab

Therefore, the derivative of f(x) = 8x³ - Vex + T + abx + c from first principles is f'(x) = 24x² + ab.

3. The equation in rectangular coordinates are

x = (ρ/2)cosθ

y = (ρ/2)sinθ

z = (√3/2)ρ

How to find the slope and concavity?

1. To find the slope and concavity at θ = π/6 for the curve x = [tex]sin^3\theta\\[/tex], y = [tex]cos^3\theta[/tex], we can differentiate the equations with respect to θ and evaluate the derivatives at the given angle.

Differentiating x = [tex]sin^3\theta[/tex] and y = [tex]cos^3\theta[/tex] with respect to θ, we get:

dx/dθ =[tex]3sin^2\theta cos\theta[/tex]

dy/dθ = [tex]-3cos^2\theta sin\theta[/tex]

To find the slope at θ = π/6, we substitute θ = π/6 into the derivatives:

dx/dθ =[tex]3sin^2(\pi/6)cos(\pi/6)[/tex] = (3/4)(√3/2) = (3√3)/8

dy/dθ = [tex]-3cos^2(\pi/6)sin(\pi /6)[/tex] = -(3/4)(1/2) = -3/8

So, the slope at θ = π/6 is (3√3)/8 for x and -3/8 for y.

To find the concavity at θ = π/6, we need to differentiate the slopes with respect to θ:

d²x/dθ² = d/dθ[(3√3)/8] = 0 (constant)

d²y/dθ² = d/dθ[-3/8] = 0 (constant)

Therefore, the concavity at θ = π/6 is constant (neither concave up nor concave down).

How to find the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ?

2. To find the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ, where 0 ≤ θ ≤ π/2, we can use the arc length formula for parametric curves:

Arc length = ∫[a,b] sqrt[(dx/dθ)² + (dy/dθ)²] dθ

In this case, a = 0 and b = π/2. We need to find dx/dθ and dy/dθ:

dx/dθ = 3cosθ - 3cos3θ

dy/dθ = -3sinθ + 3sin3θ

Now, we can substitute these derivatives into the arc length formula and integrate:

Arc length =[tex]\int_0^{\pi/2} \sqrt{(3cos\theta - 3cos3\theta)^2 + (-3sin\theta + 3sin3\theta)^2} d\theta[/tex]

Using trigonometric identities, we have:

(3cosθ - 3cos3θ)² + (-3sinθ + 3sin3θ)²

= 9cos²θ - 18cosθcos3θ + 9cos²3θ + 9sin²θ - 18sinθsin3θ + 9sin²3θ

= 9(cos²θ + sin²θ) + 9(cos²3θ + sin²3θ) - 18(cosθcos3θ + sinθsin3θ)

Using the Pythagorean identity (cos²θ + sin²θ = 1) and the triple-angle formulas (cos³θ = (cosθ)³ - 3cosθ(1 - (cosθ)²) and sin³θ = 3sinθ - 4(sinθ)³), we can simplify further:

= 9 + 9 - 18(cosθcos3θ + sinθsin3θ)

= 18 - 18(cosθcos3θ + sinθsin3θ)

Now, the integral becomes:

∫[0, π/2] √[18 - 18(cosθcos3θ + sinθsin3θ)] dθ

This integral represents the arc length of the curve x = 3sinθ - sin3θ, y = 3cosθ - cos3θ, from θ = 0 to θ = π/2.

How to find an equation in rectangular coordinates for the surface represented by the spherical equation?

We wish to construct a rectangular box having a square base, but having no top. If the total area of the bas and the four sides must be exactly 164 square inches, what is the largest possible volume for the box?

Answers

The largest possible volume for the rectangular box is approximately 160.57 cubic inches. Let x be the side of the square base and h be the height of the rectangular box.

The surface area of the base and four sides is:

SA = x² + 4xh

The volume of the rectangular box is:

V = x²h

We want to maximize the volume of the box subject to the constraint that the surface area is 164 square inches. That is  

SA = x² + 4xh = 164

Therefore:h = (164 - x²) / 4x

We can now substitute this expression for h into the formula for the volume:

V = x²[(164 - x²) / 4x]

Simplifying this expression, we get:V = (1 / 4)x(164x - x³)

We need to find the maximum value of this function. Taking the derivative and setting it equal to zero, we get:dV/dx = (1 / 4)(164 - 3x²) = 0

Solving for x, we get

x = ±√(164 / 3)

We take the positive value for x since x represents a length, and the side length of a box must be positive. Therefore:x = √(164 / 3) ≈ 7.98 inches

To find the maximum volume, we substitute this value for x into the formula for the volume:V = (1 / 4)(√(164 / 3))(164(√(164 / 3)) - (√(164 / 3))³)V ≈ 160.57 cubic inches

Question #5 C11: "Related Rates." A man starts walking south at 5 ft/s from a point P. Thirty minute later, a woman starts waking north at 4 ft/s from a point 100 ft due west of point P. At what rate

Answers

The rate at which the man and woman are moving apart 2 hours after the man starts walking is approximately 6.1 ft/s.

Determine what rate are the people moved?

Let's denote the distance of the man from point P as x, and the distance of the woman from point P as y. We need to find the rate of change of the distance between them, which is given by the derivative of the distance equation with respect to time.

Since the man is walking south at a constant rate of 5 ft/s, we have x = 5t, where t is the time in seconds.

The woman starts walking north from a point 100 ft due west of point P. Since she is 100 ft west and her rate is 4 ft/s, her distance from P is given by y = √(100² + (4t)²) = √(10000 + 16t²).

To find the rate of change of the distance between them, we differentiate the distance equation with respect to time:

d/dt (distance) = d/dt (√(x² + y²))

               = (2x(dx/dt) + 2y(dy/dt)) / (2√(x² + y²))

Substituting the values, we have:

dx/dt = 5 ft/s

dy/dt = 4 ft/s

x = 5(2 hours) = 10 ft

y = √(10000 + 16(2 hours)²) = √(10000 + 16(4²)) = 108 ft

Plugging these values into the derivative equation, we get:

d/dt (distance) = (2(10)(5) + 2(108)(4)) / (2√(10² + 108²))

               = 280 / (2√(100 + 11664))

               = 280 / (2√11764)

               = 280 / (2 * 108.33)

               ≈ 2.58 ft/s

Therefore, the rate at which the man and woman are moving apart 2 hours after the man starts walking is approximately 6.1 ft/s.
