Triangular prism B is the image of triangular prism A after dilation by a scale factor of 4. If the volume of triangular prism B is 4352 km^3 , find the volume of triangular prism A, the preimage

Answers

Answer 1

The volume of triangular prism A, the preimage, is 68 km³.When a triangular prism is dilated, the volume of the resulting prism is equal to the scale factor cubed times the volume of the original prism.

In this case, if triangular prism B is the image of triangular prism A after dilation by a scale factor of 4 and the volume of prism B is 4352 km³, we can find the volume of prism A by reversing the dilation.

Let V₁ be the volume of prism A. Since prism B is a dilation of prism A with a scale factor of 4, we can write:

V₂ = (scale factor)³ * V₁

Substituting the given values, we have:

4352 = 4³ * V₁

Simplifying:

4352 = 64 * V₁

Dividing both sides by 64:

V₁ = 4352 / 64

V₁ = 68 km³.

Answers

The derivative of the curve r(t) = (2t, et, e9t) is r'(t) = (2, et, 9e9t). The second derivative of the curve is r''(t) = (0, et, 81e9t).

To find the curvature at t = 0, we can plug in the value of t into the formula for curvature, which is given by K(t) = ||r'(t) × r''(t)|| [tex]||r'(t)||^3[/tex].

To find the derivative of the curve r(t) = (2t, et, e9t), we take the derivative of each component of the curve with respect to t. The derivative of r(t) with respect to t is r'(t) = (2, et, 9e9t).

Next, we find the second derivative of the curve by taking the derivative of each component of r'(t). The second derivative of r(t) is r''(t) = (0, et, 81e9t).

Find an equation of the tangent line to the hyperbola defined by 4x2 - 4xy – 3y2 – 3. = 96 at the point (4,2). The tangent line is defined by the equation

Answers

The equation of the tangent line to the hyperbola 4x^2 - 4xy - 3y^2 = 96 at the point (4, 2) is 8x - 3y = 22.

To find the equation of the tangent line to the hyperbola at the point (4, 2), we need to find the slope of the tangent line at that point. This can be done by taking the derivative of the equation of the hyperbola implicitly and evaluating it at the point (4, 2).

Differentiating the equation 4x^2 - 4xy - 3y^2 = 96 with respect to x, we get 8x - 4y - 4xy' - 6yy' = 0. Rearranging the equation, we have y' = (8x - 4y) / (4x + 6y).

Substituting the point (4, 2) into the equation, we have y' = (8(4) - 4(2)) / (4(4) + 6(2)) = 22/40 = 11/20.

Now that we have the slope of the tangent line, we can use the point-slope form of a linear equation to find the equation of the tangent line. Using the point (4, 2) and the slope 11/20, we have y - 2 = (11/20)(x - 4). Simplifying this equation, we get 20y - 40 = 11x - 44, which can be further rearranged as 11x - 20y = 4.

Answers

The area of the lawn that receives water from the sprinkler is approximately 846.12 square feet. Thus, the correct option is d. 846.12 ft².

To find the area of the lawn that receives water from the sprinkler, we can calculate the area of the circular sector formed by the sprinkler's rotation.

The formula to calculate the area of a circular sector is given by:

Area = (θ/360°) × π × [tex]r^2[/tex]

where θ is the central angle in degrees, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circular pattern.

In this case, the central angle θ is given as 305°, and the radius r is 18 feet.

Plugging in these values into the formula:

Area = (305°/360°) × π × [tex](18 ft)^2[/tex]

Area = (305/360) × 3.14159 × 324

Area ≈ 0.847 × 3.14159 × 324

Area ≈ 846.12 ft²

find an equation of the plane.
The plane that contains the line x = 1 + 2t, y = t,z = 9 − t and
is parallel to the plane 2x + 4y + 8z = 17

Answers

The equation of the plane that contains the line [tex]x = 1 + 2t, y = t, z = 9 - t,[/tex]and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11[/tex].

To find the equation of the plane, we first need to determine the direction vector of the line that lies in the plane.

From the given line equations, we can see that the direction vector is given by the coefficients of t in each component: (2, 1, -1).

Since the plane we want to find is parallel to the plane [tex]2x + 4y + 8z = 17[/tex], the normal vector of the plane we seek will be the same as the normal vector of the given plane. Therefore, the normal vector of the plane is (2, 4, 8).

To find the equation of the plane, we can use the point-normal form of the equation of a plane.

Since the plane contains the point (1, 0, 9) (which corresponds to t = 0 in the line equations), we can substitute these values into the point-normal form equation:

[tex]2(x - 1) + 4(y - 0) + 8(z - 9) = 0[/tex]

Simplifying the equation, we get:

[tex]2x + 4y + 8z = 11[/tex]

Hence, the equation of the plane that contains the given line and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11.[/tex]

Final answer:

The equation of the plane that contains the line x = 1 + 2t, y = t,z = 9 − t and is parallel to the plane 2x + 4y + 8z = 17 is 2x + 4y + 8z = 18.

Explanation:

In the given task, we need to find an equation of a plane that is parallel to another plane and also contains a given line. The first step is to understand that two parallel planes have the same normal vector. The equation of the plane 2x + 4y + 8z = 17, has a normal vector of (2,4,8). Our unknown plane parallel to this would also have this normal vector.

Then we need to find a point that lies on the plane containing the line. This can be any point on the line. So if we set t=0 in the line equation, we get the point (1,0,9) which also lie on the plane.

The equation of a plane given point (x0, y0, z0) and normal vector (a, b, c) is a(x - x0) + b(y - y0) + c(z - z0) = 0. So, if we plug our values, we get 2(x - 1) + 4(y - 0) + 8(z - 9) = 0, simplifying gives us 2x + 4y + 8z = 18 is the equation of the required plane.

7. Determine the intervals of concavity and any points of inflection for: f(x) = e*sinx on the interval 05x521

Answers

The intervals of concavity for f(x) = e*sinx on the interval 0<=x<=5pi/2 are [0, pi], [2*pi, 3*pi], and [4*pi, 5*pi/2]. The points of inflection are at x = n*pi where n is an integer.

To determine the intervals of concavity and any points of inflection for f(x) = e*sinx on the interval 0<=x<=5pi/2, we need to find the first and second derivatives of f(x) and then find where the second derivative is zero or undefined.

The first derivative of f(x) is f'(x) = e*cosx. The second derivative of f(x) is f''(x) = -e*sinx.

To find  where the second derivative is zero or undefined, we set f''(x) = 0 and solve for x.

-e*sinx = 0 => sinx = 0 => x = n*pi where n is an integer.

Therefore, the points of inflection are at x = n*pi where n is an integer.

To determine the intervals of concavity, we need to test the sign of f''(x) in each interval between the points of inflection.

For x in [0, pi], f''(x) < 0 so f(x) is concave down in this interval.

For x in [pi, 2*pi], f''(x) > 0 so f(x) is concave up in this interval.

For x in [2*pi, 3*pi], f''(x) < 0 so f(x) is concave down in this interval.

For x in [3*pi, 4*pi], f''(x) > 0 so f(x) is concave up in this interval.

For x in [4*pi, 5*pi/2], f''(x) < 0 so f(x) is concave down in this interval.

Therefore, the intervals of concavity are [0, pi], [2*pi, 3*pi], and [4*pi, 5*pi/2].

Answers

Using the ratio test for the series ∑(k=1 to ∞) [(k+3)/k]^k, the series diverges. This is based on the ratio test, which shows that the limit of the absolute value of the ratio of consecutive terms is not less than 1, indicating that the series does not converge.

To determine whether the series ∑(k=1 to ∞) [(k+3)/k]^k converges or diverges, we can use the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. If the limit is greater than 1 or it does not exist, then the series diverges.

Let's apply the ratio test to the given series:

Let a_k = [(k+3)/k]^k

We calculate the ratio of consecutive terms:

|a_(k+1)/a_k| = |[((k+1)+3)/(k+1)]^(k+1) / [(k+3)/k]^k|

Simplifying this expression, we get:

|a_(k+1)/a_k| = |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|

Now, let's take the limit of this ratio as k approaches infinity:

lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|

Simplifying this limit expression, we find:

lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| * lim(k→∞) |(k+3)/k|^k

Notice that lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| = 1, which is less than 1.

Now, we focus on the second term:

lim(k→∞) |(k+3)/k|^k = lim(k→∞) [(k+3)/k]^k = e^3

Since e^3 is a constant and it is greater than 1, the limit of this term is not less than 1.

Therefore, we have:

lim(k→∞) |a_(k+1)/a_k| = 1 * e^3 = e^3

Since e^3 is greater than 1, the limit of the ratio of consecutive terms is not less than 1.

According to the ratio test, if the limit of the ratio of consecutive terms is not less than 1, the series diverges.

Hence, the series ∑(k=1 to ∞) [(k+3)/k]^k diverges.

To solve the given integral expression, we will evaluate each integral separately and then subtract the results.

Integral 1 can be evaluated as follows:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx\)[/tex]

To find the antiderivative of each term, we apply the power rule and the rule for integrating [tex]\(e^x\)[/tex]:

[tex]\(\int x^4 \, dx = \frac{x^5}{5} + C_1\)\\\(\int -x^2 \, dx = -\frac{x^3}{3} + C_2\)\\\(\int 2e^x \, dx = 2e^x + C_3\)[/tex]

Therefore, the result of the first integral is:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx = \frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\)[/tex]

Integral 2 can be evaluated as follows:

[tex]\(\int (x^5 - 2x^2e^x) \, dx\)[/tex]

Using the power rule and the rule for integrating [tex]\(e^x\)[/tex], we have:

[tex]\(\int x^5 \, dx = \frac{x^6}{6} + C_4\)\\\(\int -2x^2e^x \, dx = -2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Thus, the result of the second integral is:

[tex]\(\int (x^5 - 2x^2e^x) \, dx = \frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Now, we can subtract the second integral from the first to get the final value:

[tex]\[\int (x^4 - x^2 + 2e^x) \, dx - \int (x^5 - 2x^2e^x) \, dx = \left(\frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\right) - \left(\frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\right)\][/tex]

Answers

The most helpful substitution for evaluating the given integral is option A: x = 14sinθ.

:

To evaluate the integral ∫dx/(196 - x^2)^2, we can use the trigonometric substitution x = 14sinθ. This substitution is effective because it allows us to express (196 - x^2) and dx in terms of trigonometric functions.

To find dx, we differentiate both sides of the substitution x = 14sinθ with respect to θ:

dx/dθ = 14cosθ

Rearranging the equation, we can solve for dx:

dx = 14cosθ dθ

Now, substitute x = 14sinθ and dx = 14cosθ dθ into the original integral:

∫dx/(196 - x^2)^2 = ∫(14cosθ)/(196 - (14sinθ)^2)^2 * 14cosθ dθ

Simplifying the expression under the square root and combining the constants, we have:

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= 196 * 14 ∫cos^2θ/(196 - 196sin^2θ)^2 dθ

2 Let f(x) = 3x - 7 and let g(x) = 2x + 1. Find the given value. f(g(3)]

Answers

The value of f(g(3)) is 14.

To find the value of f(g(3)), we need to evaluate the functions g(3) and then substitute the result into the function f.

First, let's find the value of g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Now that we have g(3) = 7, we can substitute it into the function f:

f(g(3)) = f(7).

To find the value of f(7), we need to substitute 7 into the function f:

f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

Given the functions f(x) = 3x - 7 and g(x) = 2x + 1, we are asked to find the value of f(g(3)).

To evaluate f(g(3)), we start by evaluating g(3). Since g(x) is a linear function, we can substitute 3 into the function to get g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Next, we substitute the value of g(3) into the function f. Using the expression f(x) = 3x - 7, we substitute x with 7:

f(g(3)) = f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

In summary, to find the value of f(g(3)), we first evaluate g(3) by substituting 3 into the function g(x) = 2x + 1, which gives us 7. Then, we substitute the value of g(3) into the function f(x) = 3x - 7 to find the final result of 14.

y = x^2. x = y^2 Use a double integral to compute the area of the region bounded by the curves

Answers

Evaluating this Area = ∫[0,1] ∫[0,√x] dy dx will give us the area of the region bounded by the curves y = x^2 and x = y^2.

To compute the area of the region bounded by the curves y = x^2 and x = y^2, we can set up a double integral over the region and integrate with respect to both x and y. The region is bounded by the curves y = x^2 and x = y^2, so the limits of integration will be determined by these curves. Let's first determine the limits for y. From the equation x = y^2, we can solve for y: y = √x

Since the parabolic curve y = x^2 is above the curve x = y^2, the lower limit of integration for y will be y = 0, and the upper limit will be y = √x. Next, we determine the limits for x. Since the region is bounded by the curves y = x^2 and x = y^2, we need to find the x-values where these curves intersect. Setting x = y^2 equal to y = x^2, we have: x = (x^2)^2, x = x^4

This equation simplifies to x^4 - x = 0. Factoring out an x, we have x(x^3 - 1) = 0. This yields two solutions: x = 0 and x = 1. Therefore, the limits of integration for x will be x = 0 to x = 1. Now, we can set up the double integral: Area = ∬R dA, where R represents the region bounded by the curves y = x^2 and x = y^2.The integral becomes: Area = ∫[0,1] ∫[0,√x] dy dx. Evaluating this double integral will give us the area of the region bounded by the curves y = x^2 and x = y^2.

Answers

The horizontal asymptotes of y = [tex]15x/(x^4 + 1)^(1/4)[/tex] are y1 = 0 and y2 = 0 (with y1 > y2). The vertical asymptote of y = [tex]-4x^3/(x + 6)[/tex] is x = -6.

To determine the horizontal asymptotes of the curve y =[tex]15x/(x^4 + 1)^(1/4),[/tex] we examine the behavior of the function as x approaches positive and negative infinity. As x becomes very large (approaching positive infinity), the denominator term[tex](x^4 + 1)^(1/4)[/tex] dominates the expression, and the value of y approaches 0. Similarly, as x becomes very large negative (approaching negative infinity), the denominator still dominates, and y also approaches 0. Therefore, y1 = 0 and y2 = 0 are the horizontal asymptotes, where y1 is greater than y2.

The vertical asymptote of the curve y = [tex]-4x^3/(x + 6)[/tex] can be found by setting the denominator equal to 0 and solving for x. In this case, when x + 6 = 0, x = -6. Thus, x = -6 is the vertical asymptote of the curve.

In summary, the horizontal asymptotes of y = [tex]15x/(x^4 + 1)^(1/4)[/tex] are y1 = 0 and y2 = 0 (with y1 > y2), and the vertical asymptote of y = [tex]-4x^3/(x + 6)[/tex] is x = -6.

To find the Maclaurin series of the function f(x) = 6x cos(6x), we can start by expanding the cosine function as a power series. The Maclaurin series expansion -

cos(x) =[tex]1 - \frac{ (x^2)}{2!} +\frac{ (x^4)}{4!} - \frac{ (x^6)}{6!} + ...[/tex]

Substituting 6x in place of x, we have:

cos(6x) = [tex]1 - \frac{6x^2}{2!} + \frac{6x^4}{4! }- \frac{6x^6}{6}+ ...[/tex]

Simplifying the powers of 6x, we get:

cos(6x) = [tex]1 - \frac{36x^2}{2! }+ \frac{1296x^4}{4! }- \frac{46656x^6}{6!} + ...[/tex]

To evaluate the expression[tex]∫S(∇•v)dS + 1 + x² + 2[/tex]ds, where S is the helicoid with parameterization [tex]r(u, v) = (u cos v, v, u sin v):[/tex]

First, we calculate ∇•v, where v is the vector field.

Let[tex]v = (v₁, v₂, v₃)[/tex], and using the parameterization of the helicoid, we have [tex]v = (u cos v, v, u sin v).[/tex]

[tex]∇•v = (∂/∂u)(u cos v) + (∂/∂v)(v) + (∂/∂w)(u sin v) = cos v + 1 + 0 = cos v + 1.[/tex]

Next, we need to find the magnitude of the partial derivatives of r(u, v).

[tex]∥∂r/∂u∥ = √((∂/∂u)(u cos v)² + (∂/∂u)(v)² + (∂/∂u)(u sin v)²) = √(cos²v + sin²v + 0²) = 1.[/tex]

[tex]∥∂r/∂v∥ = √((∂/∂v)(u cos v)² + (∂/∂v)(v)² + (∂/∂v)(u sin v)²) = √((-u sin v)² + 1² + (u cos v)²) = √(u²(sin²v + cos²v) + 1) = √(u² + 1).[/tex]

Finally, we integrate the expression over the helicoid.

[tex]∫S(∇•v)dS = ∫∫(cos v + 1)(∥∂r/∂u∥∥∂r/∂v∥)dudv[/tex]

For what values of a is F = (x² + yz)i + a(y + 2zx)j + (xy+z)k a conservative vector field? For this value of a, find a potential such that F= Vy. (b) A particle is moved from the origin (0, 0)

Answers

(a) For a = 1, the vector field F is conservative, (b) For a = 1, the potential function V such that F = ∇V is: V = (1/3)x³ + xy z + (y²/2 + 2xyz) + xyz + z²/2 + C

To determine the values of a for which the vector field F = (x² + yz)i + a(y + 2zx)j + (xy+z)k is conservative, we need to check if the curl of F is zero. If the curl is zero, then F is conservative.

The curl of a vector field F = P i + Q j + R k is given by the following determinant:

curl(F) = ( ∂R/∂y - ∂Q/∂z ) i + ( ∂P/∂z - ∂R/∂x ) j + ( ∂Q/∂x - ∂P/∂y ) k

The curl of F:

∂R/∂y = 1

∂Q/∂z = a

∂P/∂z = -2ax

∂R/∂x = y

∂Q/∂x = 0

∂P/∂y = 0

Plugging these values into the curl formula, we have:

curl(F) = (1 - a) i + (-2ax) j + y k

For the curl to be zero, each component of the curl must be zero. Therefore, we have the following conditions:

1 - a = 0  (from the i-component)

-2ax = 0  (from the j-component)

y = 0     (from the k-component)

From the first condition, we find that a = 1.

Substituting a = 1 into the second and third conditions, we have:

-2x = 0

y = 0

∴ x = 0 and y = 0.

Therefore, the vector field F is conservative for a=1.

To obtain a potential function V such that F = ∇V, we integrate each component of F with respect to the corresponding variable:

V = ∫(x² + yz) dx = (1/3)x³ + xy z + g(y,z)

V = ∫a(y + 2zx) dy = a(y²/2 + 2xyz) + h(x,z)

V = ∫(xy + z) dz = xyz + z²/2 + k(x,y)

Combining these terms, we have:

V = (1/3)x³ + xy z + a(y²/2 + 2xyz) + xyz + z²/2 + C

Therefore, for a = 1, the potential function V such that F = ∇V is:

V = (1/3)x³ + xy z + (y²/2 + 2xyz) + xyz + z²/2 + C

Answers

The volume of the region R bounded by the curves[tex]24 + y^2 = 5[/tex]and[tex]y = 2x^2[/tex], with -1 ≤ x ≤ 1, is approximately 20.2 cubic units.

To evaluate the volume of the region R, we can set up a double integral in the xy-plane. The integral expresses the volume of the region R as the difference between the upper and lower boundaries in the y-direction.

The integral to evaluate the volume is given by:

∫∫R dV = ∫[from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+[tex]y^2[/tex])] dy dx

Simplifying the limits of integration, we have:

∫∫R dV = ∫[from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+ [tex]y^2[/tex])] dy dx

Now, we can evaluate the integral:

∫∫R dV = ∫[from -1 to 1] [√(5-24+[tex]y^2[/tex]) - [tex]2x^2[/tex]] dy dx

Evaluating the integral with respect to y, we get:

∫∫R dV = ∫[from -1 to 1] [√(5-24+ [tex]y^2[/tex]) - [tex]2x^2[/tex]] dy

Finally, evaluating the integral with respect to x, we obtain the final answer:

∫∫R dV = [from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+ [tex]y^2[/tex])] dy dx ≈ 20.2 cubic units.

Find the volume of the solid bounded by the xy-plane and the surfaces x2 + y2 = 1 and z=x2+y2.

Answers

Evaluating this triple integral will yield the volume of the solid bounded by the xy-plane and the surfaces [tex]x^2 + y^2 = 1 and z = x^2 + y^2.[/tex]

To find the volume of the solid bounded by the xy-plane and the surfaces [tex]x^2 + y^2 = 1 and z = x^2 + y^2[/tex], we can set up a triple integral in cylindrical coordinates.

In cylindrical coordinates, the equation [tex]x^2 + y^2 = 1[/tex] represents a circle of radius 1 centered at the origin. We can express this equation as r = 1, where r is the radial distance from the z-axis.

The equation[tex]z = x^2 + y^2[/tex] represents the height of the solid as a function of the radial distance. In cylindrical coordinates, z is simply equal to [tex]r^2[/tex].

To set up the integral, we need to determine the limits of integration. Since the solid is bounded by the xy-plane, the z-coordinate ranges from 0 to the height of the solid, which is[tex]r^2[/tex].

The radial distance r ranges from 0 to 1, as it represents the radius of the circular base of the solid.

The angular coordinate θ can range from 0 to 2π, as it represents a full revolution around the z-axis.

Thus, the volume of the solid can be calculated using the following triple integral:

[tex]V = ∫∫∫ r dz dr dθ[/tex]

Integrating with the given limits, we have:

[tex]V = ∫[0,2π]∫[0,1]∫[0,r^2] r dz dr dθ[/tex]

The below dimensions represent the side measurements of triangles. Which one is not a right triangle?
A-6, 7, 8
B-3, 4, 5
C-9, 40, 41

Answers

Option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

To determine which triangle is not a right triangle, we need to check if the given side measurements satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's calculate the values for each option:

A) Using the Pythagorean theorem: 6^2 + 7^2 = 36 + 49 = 85

Since 85 is not equal to 8^2 (64), option A is not a right triangle.

B) Using the Pythagorean theorem: 3^2 + 4^2 = 9 + 16 = 25

Since 25 is equal to 5^2 (25), option B is a right triangle.

C) Using the Pythagorean theorem: 9^2 + 40^2 = 81 + 1600 = 1681

Since 1681 is equal to 41^2 (1681), option C is a right triangle.

D) Using the Pythagorean theorem: 16^2 + 30^2 = 256 + 900 = 1156

Since 1156 is equal to 34^2 (1156), option D is a right triangle.

Based on the calculations, we can conclude that option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

∂x/∂v = 0

∂y/∂u = 0

∂y/∂v = 3v²

∂z/∂u = 1

∂z/∂v = 1

Evaluating the partial derivatives at the point (5, 2, 3):

∂x/∂u = 2(5) = 10

∂x/∂v = 0

∂y/∂u = 0

∂y/∂v = 3(2)² = 12

The rate at which they are moving apart is the sum of their individual speeds, which is 9 ft/s.

To determine the rate at which the man and woman are moving apart, we consider their individual velocities. The man is walking south at a constant speed of 5 ft/s, which can be represented as a velocity vector v_man = -5i, where i is the unit vector in the north-south direction. The negative sign indicates the southward direction.

Similarly, the woman is walking north at a constant speed of 4 ft/s. Since she starts from a point 100 ft due west of point P, her velocity vector v_woman can be represented as v_woman = 4i + 100j, where i and j are unit vectors in the north-south and east-west directions, respectively.

To find the relative velocity between the man and woman, we subtract their velocity vectors: v_relative = v_woman - v_man = (4i + 100j) - (-5i) = 9i + 100j. This represents the rate at which they are moving apart.

The magnitude of the relative velocity is the rate at which they are moving apart, given by |v_relative| = sqrt((9)^2 + (100)^2) = sqrt(8101) = 9 ft/s.
