The approximation of f(2.98, 4.03) using total differentials is approximately 1.8424.

To approximate the value of f(2.98, 4.03) using total differentials, we can start by finding the partial derivatives of f(x, y) with respect to x and y.

The partial derivative of f(x, y) with respect to x is ∂f/∂x = (2x) / (√x² + y²).

The partial derivative of f(x, y) with respect to y is ∂f/∂y = (2y) / (√x² + y²).

Using these partial derivatives, we can calculate the total differential of f(x, y) as:

df = (∂f/∂x) dx + (∂f/∂y) dy.

To approximate f(2.98, 4.03), we need to find the values of dx and dy. Since we are given the point (0, 0) and the point (2.98, 4.03), we can find dx and dy as:

dx = 2.98 - 0 = 2.98,

dy = 4.03 - 0 = 4.03.

Substituting these values into the total differential equation, we get:

df = (∂f/∂x) dx + (∂f/∂y) dy

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

Now we can evaluate df at the point (2.98, 4.03):

df ≈ (2 * 2.98) / (√(2.98)² + (4.03)²) * 2.98 + (2 * 4.03) / (√(2.98)² + (4.03)²) * 4.03.

Calculating this expression, we find that df ≈ 1.8424.

Therefore, the approximation of f(2.98, 4.03) using total differentials is approximately 1.8424.

Answer:

By the mean value theorem, there exists a number c in the interval [-2,1] such that f'(c) = (f(1) - f(-2))/(1 - (-2)).

We have f(x) = 4x^2, so f'(x) = 8x.

Therefore, f'(c) = 8c and

(f(1) - f(-2))/(1 - (-2)) = (4(1)^2 - 4(-2)^2)/(1 - (-2)) = (4-16)/3 = -4/3.

So we need to solve the equation 8c = -4/3 for c in the interval [-2,1].

The only solution in the interval is c = -2/3, so the answer is (e) -2/3.

Since $g(x,y) \neq 0$ for all[tex]$(x,y)$,[/tex]it follows that the function [tex]$h(x,y)$[/tex] is continuous everywhere as well. Hence, the correct answer is (G) (iii) only.

The following function that is continuous at (0, 0) is h(x, y) = [tex]$\frac{x^2 + y^2}{x^2 + y^2 + 1} - 1$[/tex]. Let's check for the rest of the given functions whether they are continuous at (0,0) or not.

(i) f(x,y) = [tex]$\frac{x^8 + 6y^2}{x^8 + y^6}$[/tex]

The function is not continuous at (0, 0) because the limit is not the same for all paths that approach (0,0). Consider the limit along the path y=mx. If m is a nonzero constant, then the limit is equal to 6. However, if the path y=x^3 is taken, the limit is equal to 0. Thus, the function is not continuous at (0,0).

(ii) [tex]g(x,y) = $\frac{x^6 + 2y^6}{xy^5}$[/tex]

The function is not continuous at (0, 0) because the limit does not exist. Consider the limit along the path y=mx. If m is a nonzero constant, then the limit is equal to infinity. However, if the path y=x^2 is taken, the limit is equal to 0. Thus, the function is not continuous at (0,0).

(iii)[tex]h(x,y) = $\frac{x^2 + y^2}{x^2 + y^2 + 1} - 1$[/tex]

The function is continuous at (0,0) because it is the difference of two continuous functions. The function [tex]$f(x,y) = x^2 + y^2$[/tex] is continuous everywhere, and the function

[tex]$g(x,y) = x^2 + y^2 + 1$[/tex] is continuous everywhere.

Since $g(x,y) \neq 0$ for all[tex]$(x,y)$,[/tex]it follows that the function [tex]$h(x,y)$[/tex] is continuous everywhere as well. Hence, the correct answer is (G) (iii) only.

The equation of the tangent plane to the surface at the point (2, 1, 1) is 2y - z = -1.

Answer: 2y - z = -1.

Given the parametric surface r(u,v) = ⟨2u, uv, v²⟩, we are tasked with finding the equation of the tangent plane to this surface at the point (2, 1, 1).

To begin, we find the partial derivatives of the surface with respect to the parameters u and v:

∂r/∂u = ⟨2, 0, 0⟩

∂r/∂v = ⟨0, u, 2v⟩

At the point (2, 1, 1), we evaluate these partial derivatives:

∂r/∂u = ⟨2, 0, 0⟩

∂r/∂v = ⟨0, 1, 2⟩

To find the normal vector to the surface at this point, we take the cross product of these partial derivatives:

N(2, 1, 1) = ∂r/∂u × ∂r/∂v

= ⟨2, 0, 0⟩ × ⟨0, 1, 2⟩

= ⟨0, -4, 0⟩

Now that we have the normal vector ⟨0, -4, 0⟩, we can write the equation of the tangent plane using the point-normal form of the equation of a plane:

0(x - 2) - 4(y - 1) + 0(z - 1) = 0

Simplifying, we get:

-4y + 2z = 2

The derivative of the function f(x) = 6x^(3/5) + 5√(√x) can be expressed as f'(x) = (6/5)x^(-2/5) + (5/2)x^(-1/4).

To find the derivative of the given function f(x) = 6x^(3/5) + 5√(√x), we can apply the power rule for differentiation. The power rule states that for a function of the form f(x) = ax^n, the derivative is given by f'(x) = anx^(n-1).

Applying the power rule to the first term, 6x^(3/5), we have:

Derivative of 6x^(3/5) = (3/5)(6)x^(3/5 - 1) = (18/5)x^(-2/5).

For the second term, 5√(√x), we can simplify it as 5(x^(1/2))^(1/2) = 5x^(1/4). Applying the power rule to this term, we have:

Derivative of 5x^(1/4) = (1/4)(5)x^(1/4 - 1) = (5/4)x^(-3/4).

Combining the derivatives of both terms, we get:

f'(x) = (18/5)x^(-2/5) + (5/4)x^(-3/4).

Therefore, the derivative of f(x) = 6x^(3/5) + 5√(√x) is f'(x) = (18/5)x^(-2/5) + (5/4)x^(-3/4), where A = 18/5, B = -2/5, C = 0, D = -3/4, E = 0, and F = 0.

To calculate the length of the cardioid curve given by the polar equation r = 3 + 3cos(θ), we can use the arc length formula for polar curves: Therefore, the length of the cardioid curve is 4π√2.

L = ∫[α, β] √(r² + (dr/dθ)²) dθ

In this case, we have r = 3 + 3cos(θ). To find the limits of integration α and β, we need to determine the interval in which the curve is traced.

For the cardioid, the curve is traced from θ = 0 to θ = 2π. Thus, we have α = 0 and β = 2π.

Now, let's calculate the derivative of r with respect to θ, (dr/dθ):

(dr/dθ) = -3sin(θ)

Next, we substitute r, (dr/dθ), α, and β into the arc length formula and integrate:

L = ∫[0, 2π] √((3 + 3cos(θ))² + (-3sin(θ))²) dθ

Simplifying the expression under the square root:

L = ∫[0, 2π] √(9 + 18cos(θ) + 9cos²(θ) + 9sin²(θ)) dθ

L = ∫[0, 2π] √(9 + 18cos(θ) + 9) dθ

L = ∫[0, 2π] √(18cos(θ) + 18) dθ

L = √18 ∫[0, 2π] √(cos(θ) + 1) dθ

Now, we use the half-angle identity cos(θ/2) = √((1 + cos(θ)) / 2) to simplify the integral:

L = √18 ∫[0, 2π] √(2cos²(θ/2)) dθ

L = √18 ∫[0, 2π] √2|cos(θ/2)| dθ

Since the absolute value of cos(θ/2) is symmetric over the interval [0, 2π], we can rewrite the integral as:

L = 2√2 ∫[0, π] √(cos(θ/2)) dθ

To evaluate this integral, we can use the substitution u = θ/2, which implies du = (1/2)dθ:

L = 2√2 ∫[0, π] √(cos(u)) (2du)

L = 4√2 ∫[0, π] √(cos(u)) du

This is a standard integral, and its value is 4√2 * B(1/2, 1/2), where B is the beta function. The beta function evaluates to π, so:

L = 4√2 * π

L = 4π√2

Therefore, the length of the cardioid curve is 4π√2.

One of the statements that is not true about confidence intervals for the mean of a random variable following a normal distribution with unknown mean and variance is that the confidence interval width decreases as the sample size increases.

A confidence interval is an estimate of the range within which the true population parameter (in this case, the mean) is likely to fall. The width of the confidence interval depends on several factors, including the level of confidence chosen and the sample size. However, one of the statements that is not true about confidence intervals is that the confidence interval width decreases as the sample size increases.

In fact, the width of the confidence interval is inversely proportional to the square root of the sample size. As the sample size increases, the width of the confidence interval tends to decrease, but the decrease is not linear. The decrease in width becomes smaller as the sample size gets larger. This means that doubling the sample size will not necessarily halve the width of the confidence interval. The relationship between the sample size and the width of the confidence interval follows the square root rule.

Therefore, it is incorrect to state that the confidence interval width decreases as the sample size increases. While increasing the sample size generally leads to narrower confidence intervals, the decrease in width becomes less significant as the sample size increases, following the square root rule.

Therefore, the graph of lim x→2 f(x) = 5 is a horizontal line at y = 5.

The function f(x) = 5 is a constant function, which means it does not depend on the value of x. The graph of f(x) = 5 is a horizontal line at y = 5 because the y-coordinate is always 5 regardless of the x-coordinate.

When we consider the limit of f(x) as x approaches 2 (written as lim x→2 f(x)), we are interested in the behavior of the function as x gets arbitrarily close to 2. Since f(x) is constantly equal to 5 for all x, the value of f(x) does not change as x approaches 2. Therefore, the limit of f(x) as x approaches 2 is also 5.

In terms of the graph, the limit lim x→2 f(x) = 5 corresponds to a vertical line at x = 2 intersecting the horizontal line y = 5. This confirms that the limit of f(x) as x approaches 2 is a horizontal line at y = 5.

Therefore, the differential equation that describes the relationship is:

dS/dt = 0.3S(t)

(b) To solve the differential equation, we can separate variables and integrate.

Separating variables:

1/S(t) dS = 0.3 dt

Integrating both sides:

∫1/S(t) dS = ∫0.3 dt

Using the fact that the integral of 1/x is ln|x|, and integrating:

ln|S(t)| = 0.3t + C

Where C is the constant of integration.

To find the value of the constant C, we can use the initial condition that in the year 2014 (t = 0), the world solar PV market installations were 178,391 megawatts (S(0) = 178391):

ln|178391| = 0.3(0) + C

ln|178391| = C

Therefore, the constant C is ln|178391|.

Substituting the value of C back into the equation:

ln|S(t)| = 0.3t + ln|178391|

To eliminate the absolute value, we can exponentiate both sides:

|S(t)| = e^(0.3t + ln|178391|)

Since S(t) represents the world solar PV market installations, it cannot be negative. Therefore, we can drop the absolute value:

S(t) = e^(0.3t + ln|178391|)

Simplifying further using the property of logarithms:

S(t) = e^(0.3t) * 178391

To find the area of the region enclosed by the graphs of y = ln(x)/(5x) and y = (ln(x))^2/(5x), we need to find the points of intersection between the two curves and then calculate the definite integral of their difference over the corresponding interval.

To determine the points of intersection, we set the two equations equal to each other and solve for x:

ln(x)/(5x) = (ln(x))^2/(5x).

By cross-multiplying and rearranging, we get:

ln(x) * (ln(x))^2 = x.

Taking the exponential of both sides, we have:

Simplifying further, we obtain:

x^(ln(x))^2 - x = 0.

This equation does not have an elementary solution, so we can solve it numerically using approximation methods or graphing tools to find the x-values of the points of intersection.

Once we have the x-values of the intersection points, we can evaluate the definite integral of the difference between the two curves over the interval of interest. The area can be calculated as the absolute value of the integral.

Using symbolic notation and fractions, the area of the region enclosed by the given curves can be expressed as:

Area = ∫[a,b] [(ln(x))^2/(5x) - ln(x)/(5x)] dx.

Evaluating this integral over the interval [a,b], where a and b are the x-values of the points of intersection, will give us the desired area.

Given the condition dxdy = 1 and dydx = 0, we can conclude that the curve has a horizontal tangent line. This is because dy/dx = 0 implies that the slope with respect to x is zero, and dx/dy = 1 implies that the slope with respect to y is 1.

In other words, at any point on the curve y = f(x), the tangent line will be horizontal since the slope is zero with respect to x and the slope with respect to y is 1.

The volume of the solid generated by revolving the given triangle about the y-axis is 6π cubic units.

The volume of the solid generated by revolving the region enclosed by the triangle about the y-axis can be calculated using the method of cylindrical shells. The main answer can be summarized as: "The volume of the solid is 2π cubic units."

In more detail, let's consider the given triangle with vertices (3,2), (3,5), and (5,5). The base of the solid is the triangle itself, and by revolving it about the y-axis, we obtain a solid with rotational symmetry.

To find the volume, we integrate the area of each cylindrical shell that makes up the solid. Each shell is infinitesimally thin and has a radius equal to the x-coordinate of the triangle at the corresponding y-value. The height of each shell is the difference in y-values of the triangle at that x-coordinate.

The y-values of the triangle range from 2 to 5. Therefore, we integrate from y = 2 to y = 5. For each value of y, the corresponding x-coordinate ranges from 3 to 5, which gives us the radius of each cylindrical shell.

The integral to calculate the volume using cylindrical shells is given by:

V = 2π ∫[2,5] x (5 - 2) dy.

Simplifying the integral, we have:

V = 2π ∫[2,5] 3x dy.

Since the x-coordinate of the triangle is constant within the given range of y, we can pull it out of the integral:

V = 2π(3) ∫[2,5] x dy.

The integral of x with respect to y gives us the value of the x-coordinate at each y-value:

V = 2π(3) ∫[2,5] x dy = 2π(3) [x] from 2 to 5 = 2π(3)(5 - 2) = 6π.

Hence, the volume of the solid generated by revolving the given triangle about the y-axis is 6π cubic units.

[tex]$$ f'(x) = [g(x)h'(x) + h(x)g'(x)] $$[/tex]

Where, g(x) = 5x - 3, h(x) = 3x + 5, g'(x) = derivative of g(x) and h'(x) = derivative of h(x).

[tex]$$ g'(x) = d/dx (5x - 3) = 5 $$ $$[/tex], [tex]h'(x) = d/dx (3x + 5) = 3 $$[/tex]

Substitute the values in the product rule to get the derivative:[tex]$$ f'(x) = [ (5x - 3) (3) + (3x + 5) (5) ] $$$$ f'(x) = 15x - 9 + 15x + 25 $$ $$ f'(x) = 30x + 16 $$[/tex]

Hence, the derivative of the given function f(x) = (5x - 3) (3x + 5) is f'(x) = 30x + 16.

The given point is (2, 2) and the equation of the parabola is y = 2 - x². The point that is closest to the given point will be the point on the parabola with the shortest distance to (2, 2).Now, let's suppose that (x, y) is the point on the parabola closest to (2, 2).

Then we can use the distance formula to find the distance between (2, 2) and (x, y):d = √[(x - 2)² + (y - 2)²]Substituting the value of y from the equation of the parabola, we get:

d = √[(x - 2)² + (2 - x² - 2)²]

Simplifying,

d = √[(x - 2)² + (4 - x²)²]

We want to minimize this distance. Since √ is a monotonically increasing function, it follows that we can minimize d² instead:

d² = (x - 2)² + (4 - x²)² = x⁴ - 8x² + 16x + 20.

To minimize this function, we take the :

d²/dx = 4x³ - 16x + 16.

Setting this equal to zero and solving for x, we get:x = ±√2Now, we need to determine which of these two points is closest to (2, 2).

We can do this by computing the distance between each point and (2, 2):

d(√2) = √[(√2 - 2)² + (2 - (√2)²)²] ≈ 2.168d(-√2) = √[(-√2 - 2)² + (2 - (-√2)²)²] ≈ 3.130.

Thus, the point on the parabola closest to (2, 2) is approximately (2 - √2, 2 + (√2)²) or (2 + √2, 2 + (√2)²).

The distance between two points in the coordinate plane is given by the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²].

The point on the parabola closest to (2, 2) will be the point with the shortest distance to (2, 2). Therefore, if (x, y) is the point on the parabola closest to (2, 2), then we have:

d = √[(x - 2)² + (y - 2)²].

Since the parabola is given by y = 2 - x², we can substitute this expression for y:d = √[(x - 2)² + (2 - x² - 2)²].

Simplifying,d = √[(x - 2)² + (4 - x²)²]Now, we want to minimize d. However, it is easier to minimize d² instead. To do this, we take the derivative of d² with respect to x:

d²/dx = 4x³ - 16x + 16.

Setting this equal to zero and solving for x, we get:x = ±√2Now, we need to determine which of these two points is closest to (2, 2). We can do this by computing the distance between each point and (2, 2):

d(√2) = √[(√2 - 2)² + (2 - (√2)²)²] ≈ 2.168d(-√2) = √[(-√2 - 2)² + (2 - (-√2)²)²] ≈ 3.130.

Thus, the point on the parabola closest to (2, 2) is approximately (2 - √2, 2 + (√2)²) or (2 + √2, 2 + (√2)²).

The point on the parabola \( y=2-x^{2} \) that is closest to the point \( (2,2) \) is approximately (2 - √2, 2 + (√2)²) or (2 + √2, 2 + (√2)²).

The plot will show the initial point represented by a red dot (-4-7i) and the result represented by a blue dot (-27+21i) on the complex plane.

To visualize the multiplication of (-4-7i)(2-5i), we can plot the initial point and the result on the complex plane. Let's go through the steps to calculate and plot it.

First, let's calculate the multiplication:

(-4-7i)(2-5i)

Using the FOIL method, we can expand this expression:

(-4)(2) + (-4)(-5i) + (-7i)(2) + (-7i)(-5i)

Simplifying further:

(-8 + 20i - 14i - 35i²)

Since \(i² = -1\), we can substitute it:

(-8 + 20i - 14i - 35(-1))

(-8 + 20i - 14i + 35)

(-8 + 21i + 35)

(-27 + 21i)

The result of the multiplication is (-27 + 21i).

Now, let's plot the initial point, which is (-4-7i), and the result, (-27 + 21i), on the complex plane:

```python

import matplotlib.pyplot as plt

# Initial point (-4-7i)

initial_point = complex(-4, -7)

# Result (-27+21i)

result = complex(-27, 21)

# Plotting

plt.plot(initial_point.real, initial_point.imag, 'ro', label='Initial Point (-4-7i)')

plt.plot(result.real, result.imag, 'bo', label='Result (-27+21i)')

plt.axhline(0, color='black', linewidth=0.5)

plt.axvline(0, color='black', linewidth=0.5)

plt.xlabel('Real')

plt.ylabel('Imaginary')

plt.title('Complex Multiplication')

plt.legend()

plt.grid(True)

An antiderivative F(x) with F'(x) = f(x) = 4 + 24x^3 + 10x^4, and F(1) = 0 is given by:
F(x) = x^4 + 6x^2 + 2x^5/5 - 4/5 + C, where C is an arbitrary constant.

To find an antiderivative F(x) of f(x) = 4 + 24x^3 + 10x^4, we need to find a function whose derivative is f(x). We can use the power rule of integration to integrate each term of f(x) separately:

∫ 4 dx = 4x + C1

∫ 24x^3 dx = 6x^4 + C2

∫ 10x^4 dx = 2x^5 + C3

where C1, C2, and C3 are arbitrary constants of integration.

Therefore, an antiderivative of f(x) is given by:

F(x) = 4x + 6x^4 + 2x^5/5 + C

To find the value of the constant C, we use the initial condition F(1) = 0:

F(1) = 4(1) + 6(1)^4 + 2(1)^5/5 + C = 0

Simplifying, we get:

10/5 + C = 0

C = -2

Therefore, the antiderivative we seek is:

F(x) = x^4 + 6x^2 + 2x^5/5 - 4/5 + C

Substituting the value of C, we get:

F(x) = x^4 + 6x^2 + 2x^5/5 - 4/5 - 2

a) The given vector field is conservative since its curl is zero. b) Without the missing component and the parameterization, it is not possible to evaluate the line integral or the surface integral in this case.

To find the potential function for the vector field Ĕ, we integrate each component of the vector field with respect to its corresponding variable. Integrating the first component, we get ∫4 dx = 4x + C₁. Integrating the second component, we have ∫209 dy = 209y + C₂.

Integrating the third component, we get ∫20 dz = 20z + C₃. Since the last component is missing, we cannot integrate it, so we denote it as C₄. Therefore, the potential function for the vector field Ĕ is given by F = (4x + C₁, 209y + C₂, 20z + C₃, C₄).

For part b, we need to evaluate the line integral of Ĕ·dF along the curve C defined by r(t) = (tsin(27), ln(t² - 1) - 5t). Substituting the values into Ĕ·dF, we have (4, 209, 20, -)·(tsin(27), ln(t² - 1) - 5t) = 4(tsin(27)) + 209(ln(t² - 1) - 5t) + 20z + C₄, where z is the missing component of dF.

The question is incomplete, so this is a general answer

To find the volume of the solid obtained by rotating the region bounded by two curves, say f(x) and g(x), about the y-axis using the cylindrical shells method, we integrate the circumferences of infinitesimally thin cylindrical shells.

Let's assume that the curves f(x) and g(x) intersect at x = a and x = b, with f(x) lying above g(x) within this interval.

The volume of the solid can be calculated using the following integral:

V = ∫[a,b] 2πx (f(x) - g(x)) dx

Integrating from x = a to x = b, we multiply the circumference 2πx by the difference in heights between f(x) and g(x).

Finally, we integrate this expression over the given interval [a,b].

Note that if the curves are defined in terms of y instead of x, you would need to rearrange the equation and express x in terms of y.

Using this cylindrical shells method, the integral will give you the volume of the solid obtained by rotating the region bounded by the curves f(x) and g(x) about the y-axis.

The first statement, "If x and y are rational numbers, then 3x + 2y is also a rational number," can be proven using a direct proof. The second statement, "If x is a real number and x < 3, then 12 - 7x + [tex]x^{2}[/tex] > 0," can also be proved directly.

(a) To prove the first statement, let's assume that x and y are rational numbers. By definition, a rational number can be expressed as the quotient of two integers. Therefore, we can represent x as x = p/q and y as y = r/s, where p, q, r, and s are integers, and q and s are nonzero.

Now, we need to show that 3x + 2y is also a rational number. Substituting the values of x and y, we have:

3x + 2y = 3(p/q) + 2(r/s) = (3p/q) + (2r/s) = (3p + 2r)/(q*s).

Since 3p + 2r and q*s are integers (as the sum and product of integers are integers), we can conclude that 3x + 2y is indeed a rational number. Hence, the first statement has been proven using a direct proof.

(b) For the second statement, let's assume x is a real number and x < 3. We need to show that 12 - 7x + [tex]x^{2}[/tex] > 0. To prove this, we'll manipulate the expression to simplify it and show that it is greater than zero.

Starting with the expression 12 - 7x + [tex]x^{2}[/tex], we can rewrite it as ([tex]x^{2}[/tex] - 7x + 12). We can factorize this expression as (x - 3)(x - 4).

Since we assumed x < 3, it follows that x - 3 < 0. Similarly, since x < 3, we have x - 4 < -1.

Now, multiplying these two inequalities, we get (x - 3)(x - 4) > 0 * -1 = 0.

Therefore, we have (x - 3)(x - 4) > 0, which implies that 12 - 7x + [tex]x^{2}[/tex] > 0. Thus, the second statement has been proven using a direct proof.

By converting the given speed and stopping distance to appropriate units, we determined that the acceleration of the car, assuming it is constant, is approximately 112.52 miles per square hour.

To find the acceleration of the car, we need to convert the given information into appropriate units.

First, let's convert the speed from miles per hour to feet per hour. We know that 1 mile is equal to 5280 feet, and 1 hour is equal to 3600 seconds. Therefore, the speed of the car in feet per hour is:

70 mph * 5280 ft/mi = 369,600 ft/hr.

Next, we need to convert the stopping distance from feet to miles. To do this, we divide the stopping distance by the number of feet in a mile:

149 ft / 5280 ft/mi = 0.0282 mi.

Now, let's calculate the time it takes for the car to stop. We know that distance equals velocity multiplied by time (d = vt). Rearranging the equation, we have:

time (t) = distance (d) / velocity (v).

Plugging in the values, we have:

t = 0.0282 mi / 369,600 ft/hr.

Next, we need to convert the time from hours to seconds. We know that 1 hour is equal to 3600 seconds:

t = (0.0282 mi / 369,600 ft/hr) * 3600 s/hr = 0.0273 s.

Now that we have the time, we can calculate the acceleration using the formula:

acceleration (a) = change in velocity (Δv) / time (t).

Since the car went from 369,600 ft/hr to a stop, the change in velocity is 369,600 ft/hr. Therefore, the acceleration is:

a = 369,600 ft/hr / 0.0273 s.

Converting the units of acceleration to miles per square hour, we have:

a = (369,600 ft/hr * 1 mi/5280 ft) / (0.0273 s * 3600 s/hr).

Simplifying the equation, we find:

a ≈ 112.52 mi/hr^2.

Therefore, the acceleration of the car, assuming it is constant, is approximately 112.52 miles per square hour.
