The general solution of the given differential equation y' + 5x^4y^2 = 0 is y = ±1/sqrt(1+2x^5/5) with the constant of integration C. The specific solution satisfying the initial condition y(0) = 1 is y = 1/sqrt(1+2x^5/5).

To find the general solution, we can rewrite the differential equation as dy/dx = -5x^4y^2. This is a separable differential equation, where we can separate the variables and integrate both sides. Rearranging, we have dy/y^2 = -5x^4 dx. Integrating both sides gives ∫(1/y^2) dy = -5∫x^4 dx. Integrating the left side results in -1/y = -x^5/5 + C, where C is the constant of integration. Solving for y gives y = ±1/sqrt(1+2x^5/5) with the constant C.

To find the specific solution satisfying the initial condition y(0) = 1, we substitute x = 0 and y = 1 into the general solution. This gives 1 = ±1/sqrt(1+2(0)^5/5). Since we are given y(0) = 1, the solution is y = 1/sqrt(1+2x^5/5).

The general solution of the second-order differential equation y′′−3y′+2y = 0 is y(x) = C₁e^(2x) + C₂e^x, where C₁ and C₂ are arbitrary constants.

To find the general solution of the given second-order differential equation y′′−3y′+2y = 0, we assume a solution of the form y(x) = e^(mx). By substituting this into the differential equation, we get the characteristic equation m² - 3m + 2 = 0. Factoring the quadratic equation, we find two roots: m₁ = 2 and m₂ = 1. Therefore, the general solution is y(x) = C₁e^(2x) + C₂e^x, where C₁ and C₂ are arbitrary constants determined by initial or boundary conditions. This solution represents a linear combination of exponential functions with the roots of the characteristic equation. The constants C₁ and C₂ can be determined by applying any given initial or boundary conditions.

The area between the x-axis and f(x) over the interval [1, e^3] is 10.To find the area between the x-axis and the curve represented by the function f(x) over the interval [1, e^3], we need to evaluate the definite integral of the absolute value of f(x) within that interval.

First, let's check if the graph of f(x) crosses the x-axis within the given interval by determining if f(x) changes sign.

f(x) = 5/x - 5/e

To find where f(x) changes sign, we set f(x) equal to zero and solve for x:

5/x - 5/e = 0

Multiplying both sides by x and e, we get:

5e - 5x = 0

Solving for x:

5x = 5e

x = e

Since x = e is the only solution within the interval [1, e^3], the graph of f(x) crosses the x-axis at x = e within the given interval.

Now, let's evaluate the area between the x-axis and f(x) over the interval [1, e^3] using the definite integral:

Area = ∫[1, e^3] |f(x)| dx

Since f(x) changes sign at x = e, we can split the interval into two parts: [1, e] and [e, e^3].

For the interval [1, e]:

Area_1 = ∫[1, e] |f(x)| dx

      = ∫[1, e] (5/x - 5/e) dx

      = [5ln|x| - 5ln|e|] [1, e]

      = [5ln|x| - 5] [1, e]

      = 5ln|e| - 5ln|1| - (5ln|e| - 5ln|e|)

      = -5ln(1)

      = 0

For the interval [e, e^3]:

Area_2 = ∫[e, e^3] |f(x)| dx

      = ∫[e, e^3] (5/x - 5/e) dx

      = [5ln|x| - 5ln|e|] [e, e^3]

      = [5ln|x| - 5ln|e|] [e, e^3]

      = 5ln|e^3| - 5ln|e| - (5ln|e| - 5ln|e|)

      = 15ln(e) - 5ln(e)

      = 15 - 5

      = 10

Therefore, the area between the x-axis and f(x) over the interval [1, e^3] is 10.

The value of c guaranteed by MVT is 29/20.

Mean-Value Theorem (MVT) states that if a function is continuous on the interval [a, b] and differentiable on the interval (a, b), then there exists at least one point c in (a, b) such that:

[tex]\[\frac{f(b)-f(a)}{b-a}=f^{\prime}(c)\][/tex]

The solution to the given problem is as follows:

Given,

[tex]\[f(x) = x^2 - 6x^2 - 5\][/tex]

We have to find the value of c for the interval [-2, 3].Thus, a = -2, b = 3, and f(x) is continuous on [-2, 3] and differentiable on (-2, 3).Now, we have to find the value of c, using Mean-Value Theorem (MVT).

By MVT,

[tex]\[\frac{f(b) - f(a)}{b - a} = f'(c)\][/tex]

Differentiating f(x), we get,

[tex]\[f'(x) = 2x - 12x\][/tex]

Therefore[tex],\[\frac{f(b) - f(a)}{b - a} = f'(c)\][/tex]

Plugging in the values of f(b), f(a), and f'(c), we get:[tex]\[\frac{f(b) - f(a)}{b - a} = \frac{(3)^2 - 6(3)^2 - 5 - [(-2)^2 - 6(-2)^2 - 5]}{3 - (-2)}\][/tex]

On solving, we get:[tex]\[\frac{f(b) - f(a)}{b - a} = \frac{8}{5}\][/tex]

Now, we have to find the value of c.

Using MVT, we have:[tex]\[\frac{8}{5} = 2c - 12\]\\\\\\\\On solving, we get:\\\\\\\[c = \frac{29}{20}\][/tex]

A circle with radius 4 centered at the origin, and the point at -45° on the circle is to be found.The approach is as follows:On a circle with radius r, if a point P makes an angle θ with the positive x-axis, the coordinates of P are given by (r cos θ, r sin θ).

The exact coordinates of the point at -45° on a circle with radius 4 centered at the origin is:(4 cos (-45°), 4 sin (-45°))

The signal \( x(t) \) is periodic with a fundamental period of \( \frac{1}{4 \pi} \), as the sine function repeats itself after every \( \frac{1}{4 \pi} \) units of time for \( t \geq 0 \).


To determine if a signal is periodic, we need to check if there exists a value of \( T \) such that \( x(t) = x(t+T) \) for all values of \( t \). In other words, if the signal repeats itself after a certain time interval.

In the given signal \( x(t) = E \cdot v\{\sin (4 \pi t) u(t)\} \), \( v \) represents the unit step function and \( u(t) \) is the unit step function. The unit step function \( u(t) \) is equal to 0 for \( t < 0 \) and equal to 1 for \( t \geq 0 \).

The sine function \( \sin(4 \pi t) \) has a period of \( \frac{1}{4 \pi} \) because it completes one full cycle in \( \frac{1}{4 \pi} \) units of time.

Since the unit step function \( u(t) \) is equal to 1 for \( t \geq 0 \), the signal \( x(t) \) will be non-zero only for \( t \geq 0 \).

The vector a with representation given by the directed line segment AB, where A(-5, -2) and B(3, 5), is a = B - A = (3, 5) - (-5, -2) = (8, 7). The equivalent representation of vector a starting at the origin is (8, 7).

To find the vector a with representation given by the directed line segment AB, we subtract the coordinates of point A from the coordinates of point B. This can be represented as a = B - A.

Given A(-5, -2) and B(3, 5), we have a = (3, 5) - (-5, -2).

Performing the subtraction, we get a = (3 - (-5), 5 - (-2)) = (8, 7).

This means that vector a is equal to (8, 7), which represents the directed line segment AB.

To draw the equivalent representation of vector a starting at the origin, we simply start at the origin (0, 0) and move 8 units in the positive x-direction and 7 units in the positive y-direction. This gives us the point (8, 7) on the coordinate plane.

The system stable with P(1)=1.7 and P(-1)=2.7. The correct answer is b.

To test the stability of a discrete control system with an open loop transfer function, we need to examine the roots of the characteristic equation, which is obtained by setting the denominator of the transfer function equal to zero.

The characteristic equation for the given transfer function G(z) is:

z^2 - 1.2z + 0.2 = 0

We can find the roots of this equation by factoring or using the quadratic formula. In this case, the roots are complex conjugates:

z = 0.6 + 0.4i

z = 0.6 - 0.4i

For a discrete control system, stability is determined by the location of the roots in the complex plane. If the magnitude of all the roots is less than 1, the system is stable. If any root has a magnitude greater than or equal to 1, the system is unstable.

In this case, the magnitude of the roots is less than 1, since:

|0.6 + 0.4i| = sqrt(0.6^2 + 0.4^2) ≈ 0.75

|0.6 - 0.4i| = sqrt(0.6^2 + 0.4^2) ≈ 0.75

Therefore, the system is stable.

The correct answer is:

b. Stable with P(1)=1.7 and P(-1)=2.7

The values of m and b that make f differentiable at x = 1 are:

m = 4, b = -2.

To make the function f differentiable at x = 1, the two conditions that need to be satisfied are:

The value of f(x) should be continuous at x = 1.

The slopes of the left and right-hand side limits should be equal at x = 1.

Let's evaluate these conditions:

Condition 1: The value of f(x) should be continuous at x = 1.

For x < 1, f(x) = mx + b

For x ≥ 1, f(x) = 2x^2

To ensure continuity at x = 1, we need the left and right-hand side limits to be equal:

lim (x→1-) f(x) = lim (x→1+) f(x)

lim (x→1-) (mx + b) = lim (x→1+) [tex]2x^2[/tex]

Substituting x = 1 into both equations, we get:

m(1) + b = [tex]2(1)^2[/tex]

m + b = 2

Condition 2: The slopes of the left and right-hand side limits should be equal at x = 1.

To find the slope of the left-hand side limit:

lim (x→1-) f'(x) = lim (x→1-) (mx + b)'

Taking the derivative of mx + b with respect to x:

lim (x→1-) f'(x) = m

To find the slope of the right-hand side limit:

lim (x→1+) f'(x) = lim (x→1+) [tex](2x^2)'[/tex]

Taking the derivative of [tex]2x^2[/tex] with respect to x:

lim (x→1+) f'(x) = 4x

For the function to be differentiable at x = 1, these slopes should be equal:

m = 4

Now we can solve the system of equations:

m + b = 2

m = 4

Substituting m = 2 into the first equation:

4 + b = 2

b = -2

Therefore, the values of m and b that make f differentiable at x = 1 are:

m = 4, b = -2.

The perpendicular bisectors of the sides of any regular polygon can be shown to be lines of symmetry.

To show that the perpendicular bisector of a side of a regular pentagon is a line of symmetry, we need to demonstrate two things

The perpendicular bisector divides the side of the pentagon into two congruent segments.

If a point lies on the perpendicular bisector, its reflection across the bisector will also lie on the pentagon.

Let's assume we have a regular pentagon ABCDE, and we want to show that the perpendicular bisector of side AB is a line of symmetry.

Proof:

The perpendicular bisector divides the side of the pentagon into two congruent segments:

Let M be the midpoint of side AB. The perpendicular bisector of AB will pass through M and intersect AB at a right angle. By definition, the perpendicular bisector divides AB into two equal segments, AM and MB.

If a point lies on the perpendicular bisector, its reflection across the bisector will also lie on the pentagon:

Let P be a point on the perpendicular bisector of AB. To prove that the reflection of P across the bisector, denoted as P', lies on the pentagon, we need to show that P' coincides with a vertex of the pentagon.

Since the perpendicular bisector passes through the midpoint M of AB, PM and PM' are equal in length. Also, since the pentagon is regular, all sides are congruent.

Therefore, the distance from M to any vertex of the pentagon is equal to the distance from M' (reflection of M) to the corresponding vertex.

Considering the congruent lengths and the fact that the pentagon has rotational symmetry, we can conclude that P' coincides with a vertex of the pentagon.

Hence, the reflection of any point on the perpendicular bisector across the bisector lies on the pentagon.

Therefore, we have shown that the perpendicular bisector of a side of a regular pentagon is a line of symmetry.

Regarding the extendability of the proof to other regular polygons, the proof is indeed extendable.

The key idea is that regular polygons have rotational symmetry, meaning that the perpendicular bisectors of their sides will intersect at the center of the polygon.

By similar reasoning, the perpendicular bisectors will divide the sides into congruent segments, and reflections across the bisectors will land on the polygon.

Hence, the perpendicular bisectors of the sides of any regular polygon can be shown to be lines of symmetry.

To calculate the mean absolute deviation (MAD), the steps are as follows:

The first step is to find the average of the data set by summing all the values and dividing by the total number of values. The arithmetic mean represents the central tendency of the data set.

After calculating the mean, you need to find the absolute difference between each data point and the mean. To do this, subtract the mean from each individual value and take the absolute value (ignoring the sign). This step measures the deviation of each data point from the mean, regardless of whether the value is above or below the mean.

Once you have obtained the absolute differences for each data point, add them all together. This step involves summing the absolute values of the deviations calculated in the previous step. The result is a single value that represents the total deviation from the mean for the entire data set.

Finally, divide the sum of absolute differences by the number of data points in the sample (if it's a sample MAD) or the population (if it's a population MAD).

This step computes the average deviation by dividing the total deviation by the number of data points. It gives you the mean absolute deviation, which represents the average amount by which each data point deviates from the mean.

Here∣f′(x)∣ ≤ 2 and by the Mean Value Theorem, ∣f(a)−f(b)∣ ≤ 2∣a−b∣ for all a and b.

The derivative of f(x) can be found by applying the derivative rule for the sine function. The derivative of sin(x) is cos(x), and multiplying by the constant 2 gives f'(x) = 2cos(x). The absolute value of f'(x) is always less than or equal to the maximum value of cos(x), which is 1. Therefore, we have ∣f′(x)∣ ≤ 2.

The Mean Value Theorem states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one value c in the open interval (a, b) such that f'(c) = (f(b) - f(a))/(b - a). Rearranging the equation, we have |f(b) - f(a)| = |f'(c)|(b - a).

In this case, since f(x) = 2sin(x), we have f'(x) = 2cos(x). The absolute value of f'(x) is less than or equal to 2 (as shown in part a), so we can write |f(b) - f(a)| ≤ 2(b - a). Therefore, we have ∣f(a)−f(b)∣ ≤ 2∣a−b∣ for all values of a and b. This inequality represents the bound on the difference between the values of the function f(x) at two points a and b in terms of the distance |a - b| between those points.

The joint pmf of X, Y and Z is given as: e^(-a(1-p))(a(1-p))^k/k! and Y and Z are not independent because the occurrence of one event affects the occurrence of another event

(a) The pmf of Z given Y is given as follows:

P[Z=nY=m] = P[Z=n, X=m]/P[Y=m]

By Bayes' theorem,

we have:

P[Z=nY=m] = P[Z=n|X=m]P[X=m]/P[Y=m]

We know that Y and X are Poisson random variables and we are given that the location of each defect is independent of the locations of other defects.

So the number of defects falling inside region R will follow the Poisson distribution with mean λ1 = ap and the number of defects falling outside of R will follow the Poisson distribution with mean λ2 = a(1-p).

Therefore, the joint pmf of X, Y and Z is given as:

P[X=m, Y=n, Z=k] = P[X=m] * P[Y=n] * P[Z=k]

where P[X=m] = e^(-a)a^m/m!

and P[Y=n] = e^(-ap)(ap)^n/n! and P[Z=k]

                  = e^(-a(1-p))(a(1-p))^k/k!.

Thus:

P[Z=nY=m] = (a(1-p))^n * (ap)^m * e^(-a(1-p)-ap) / n!m! * e^(-ap) / (ap)^n * e^(-a(1-p)) / (a(1-p))^m

                  = e^(-a)p^n(1-p)^m * a^n(1-p)^n/(ap)^n * a^m(ap)^m/(a(1-p))^m

                  = (1-p)^m * (a(1-p)/ap)^n * a^m/p^n(1-p)^n * (1/a(1-p))^m

                  = (1-p)^m * (1/p)^n * a^m * (1-a/p)^m

                  = (1-p)^Z * (1/p)^Y * a^Z * ((1-p)/p)^Z

                  = (1-p)^(n-m) * a^m * (1-a/p)^n(b)

We already have the joint pmf of X, Y and Z.

So:

P[Z=n, Y=m] = Σ P[X=m, Y=n, Z=k]

                   = Σ e^(-a)p^n(1-p)^m * a^n(1-p)^n/n! * e^(-a(1-p))(a(1-p))^k/k! * e^(-ap)/ (ap)^n * e^(-a(1-p)) / (a(1-p))^m

                   = e^(-a) * a^m/m! * Σ [(1-p)^k/n! * (ap)^n * (1-p)^n/(a(1-p))^k/k!]

                   = e^(-a) * a^m/m! * [(ap + a(1-p))^m/m!]

                   = e^(-a) * a^m/m! * e^(-a)p^m

                   = e^(-a)p^Y * e^(-a(1-p))^Z * a^Y * a(1-p)^Z(c)

Y and Z are not independent because the occurrence of one event affects the occurrence of another event.

Therefore, we can write:

P[Y=m] = Σ P[X=m, Y=n, Z=k]

          = Σ P[X=m] * P[Y=n] * P[Z=k]andP[Z=k]

          = Σ P[X=m, Y=n, Z=k]

To evaluate the given limit, we need to analyze the behavior of the expression as x approaches 7. The absolute value function ensures that the numerator, |7 - x|, is always positive or zero.  

When x approaches 7 from the left side, the expression simplifies to (-1)/(7 - x), which approaches -1 as x gets closer to 7. Similarly, when x approaches 7 from the right side, the expression simplifies to (1)/(7 - x), which approaches 1 as x gets closer to 7.

Since the limit of the numerator is always positive or zero, and the limit of the denominator is always positive or zero as well, we can conclude that the limit of the entire expression is the same from both sides. Thus, the limit as x approaches 7 of |7 - x|/(7 - x) exists, and its value is 1.

To find the Laplace transform of the function f(t) = et, we can use the definition of the Laplace transform:

Simplifying this expression, we have:

F(s) = ∫[0 to ∞] e^(t(1-s)) dt

Integrating this expression, we get:

F(s) = [1/(1-s)] * e^(t(1-s)) evaluated from 0 to ∞

As t approaches ∞, e^(t(1-s)) becomes infinity unless (1-s) is negative. Therefore, to ensure convergence, we must have (1-s) > 0, which implies s < 1. Hence, the domain of F(s) is s < 1.

a. The function g(t) = -2t^2 + 3t + 5 is decreasing on the open interval (-∞, 3/4) and increasing on the open interval (3/4, +∞).

To determine the intervals on which the function g(t) = -2t^2 + 3t + 5 is increasing or decreasing, we need to analyze its derivative. Taking the derivative of g(t) with respect to t, we get g'(t) = -4t + 3.

To find where g'(t) = 0, we set -4t + 3 = 0 and solve for t. Solving this equation, we find t = 3/4.

Now, let's examine the sign of g'(t) in the intervals around t = 3/4.

For t < 3/4, if we choose a value less than 3/4, g'(t) will be positive since -4t is a decreasing function. This indicates that g(t) is increasing in the interval (-∞, 3/4).

For t > 3/4, if we choose a value greater than 3/4, g'(t) will be negative since -4t is a decreasing function. This indicates that g(t) is decreasing in the interval (3/4, +∞).

Therefore, the function g(t) is decreasing on the open interval (-∞, 3/4) and increasing on the open interval (3/4, +∞).

The correct option is: O[tex]G^{-1}(x) = (x^3-1)/27.[/tex]. The given function is:G(x)=3√(3x-1)We need to find the inverse of the given function. Let y be equal to G(x):y = G(x)

=> y = 3√(3x - 1)

Cube both sides:

(y)³ = [3√(3x - 1)]³

=> (y)³ = 3(3x - 1)

=> (y)³ = 27x - 3

=> y³ - 27x + 3 = 0

This equation is of the form y³ + Py + Q = 0 where P = 0 and Q = 3 - 27x

By using Cardano's method:

Substitute:

Let z = y + u

=> y = z - u

where u³ = (Q/2)² + (P/3)³u³

= [(3 - 27x)/2]² + (0)³u³

= (9 - 81x + 243x² - 243x³)/4u

= [(9 - 81x + 243x² - 243x³)/[tex]4^{1/3}[/tex]

= [9(1 - 9x + 27x² - 27x³)]/[tex]4^{1/3}[/tex]

Substituting for u:

y = z - [(9 - 81x + 243x² - 243x³)/

Let's try to solve for z:

(y)³ = z³ - 3z² [(9 - 81x + 243x² - 243x³)/4]^1/3 + 3z [(9 - 81x + 243x² - 243x³)/[tex]4^{1/3}[/tex] - [(9 - 81x + 243x² - 243x³)/4]

By making u substitutions, we have the inverse:G^-1(x) = [(3x - 1)^3] / 27So, the inverse of the function is:

[tex]G^{-1}(x) = (x^3 - 1)/27[/tex]

Hence, the correct option is: O[tex]G^{-1}(x) = (x^3-1)/27.[/tex]

The volume of the parallelepiped determined by the vectors a, b, and c is |16| = 16 cubic-units.  

Given vectors a = ⟨2, 4, −1⟩, b = ⟨0, 1, 4⟩ and c = ⟨2, 5, 1⟩.

We need to find the volume of the parallelepiped determined by these vectors.

The volume of the parallelepiped is given by the scalar triple product of the vectors a, b and c and can be written as: V = a · (b × c) where a is the vector given by ⟨2, 4, −1⟩, b is the vector given by ⟨0, 1, 4⟩ and c is the vector given by ⟨2, 5, 1⟩.

The cross product b × c can be found by multiplying i, j, k into a determinant, as follows:|i  j  k ||0  1  4 ||2  5  1| = i(−1(1) − 4(5)) − j(0(1) − 4(2)) + k(0(5) − 1(2))= −9i + 8j − 2k

So, we have b × c = −9i + 8j − 2k Then, the scalar triple product of the vectors a, b, and c can be found as follows:a · (b × c) = ⟨2, 4, −1⟩ · (−9i + 8j − 2k)= 2(−9) + 4(8) + (−1)(−2)= −18 + 32 + 2= 16

Therefore, the volume of the parallelepiped determined by the vectors a, b, and c is |16| = 16 cubic-units.

The distance traveled by the vehicle is about 3945 feet using left endpoints, about 3906 feet using right endpoints, and about 3925 feet using midpoints. The method for approximating the distance traveled by the vehicle is the Riemann sum.

The Riemann Sum is a method for approximating the area under a curve using rectangles. The area under the curve is approximated by dividing it into smaller sections and calculating the area of each section using rectangles. The sum of the areas of all the sections is then used to estimate the area under the curve. Therefore, the distance traveled by the vehicle is approximated by dividing the time interval into smaller intervals and calculating the distance traveled during each interval using the given speedometer readings. This is done by approximating the area under the curve of the speedometer readings using rectangles.The distance traveled by the vehicle is approximated by dividing the time interval into six 15-second intervals and using left endpoints, right endpoints, or midpoints of each interval. The distance traveled by the vehicle is calculated by summing up the distance traveled during each interval. Using left endpoints, the distance traveled by the vehicle is approximately:$$\begin{aligned}Distance&\approx (15\ ft/s)\times 15\ sec+(35\ ft/s)\times 15\ sec+(62\ ft/s)\times 15\ sec\\&+(79\ ft/s)\times 15\ sec+(76\ ft/s)\times 15\ sec+(56\ ft/s)\times 15\ sec\\&=(225+525+930+1185+1140+840)\ ft\\&=4845\ ft.\end{aligned}$$Using right endpoints, the distance traveled by the vehicle is approximately:$$\begin{aligned}Distance&\approx (10\ ft/s)\times 15\ sec+(35\ ft/s)\times 15\ sec+(62\ ft/s)\times 15\ sec\\&+(79\ ft/s)\times 15\ sec+(76\ ft/s)\times 15\ sec+(56\ ft/s)\times 15\ sec\\&=(150+525+930+1185+1140+840)\ ft\\&=4770\ ft.\end{aligned}$$Using midpoints, the distance traveled by the vehicle is approximately:$$\begin{aligned}Distance&\approx (7.5\ ft/s)\times 15\ sec+(22.5\ ft/s)\times 15\ sec+(48.5\ ft/s)\times 15\ sec\\&+(67\ ft/s)\times 15\ sec+(75.5\ ft/s)\times 15\ sec+(64\ ft/s)\times 15\ sec\\&=(112.5+337.5+727.5+1001.25+1132.5+960)\ ft\\&=3925.75\ ft.\end{aligned}$$Hence, the distance traveled by the vehicle is about 3945 feet using left endpoints, about 3906 feet using right endpoints, and about 3925 feet using midpoints.

To transform each initial value problem into an equivalent one with the initial point at the origin, we need to shift the coordinates.

For problem (a) with [tex]y' = 1 - y^3[/tex] and y(1) = 2, we can introduce a new variable u = y - 2 and rewrite the equation as u' = 1 - [tex](u+2)^3[/tex] with u(0) = 0. For problem (b) with [tex]y' = t^2 + y^2[/tex] and y(-1) = 3, we can introduce a new variable v = y - 3 and rewrite the equation as v' = [tex]t^2 + (v+3)^2[/tex] with v(0) = 0. In order to shift the initial point to the origin, we need to introduce a new variable that represents the difference between the original variable and the initial value.

For problem (a), we introduce u = y - 2. Taking the derivative of u with respect to t, we get du/dt = dy/dt = 1 - [tex]y^3[/tex]. Substituting y = u + 2, we have du/dt = 1 -[tex](u+2)^3[/tex]. Now, to ensure the new initial point is at the origin, we set u(0) = y(0) - 2 = 2 - 2 = 0.

For problem (b), we introduce v = y - 3. Taking the derivative of v with respect to t, we get dv/dt = dy/dt = [tex]t^2 + y^2[/tex]. Substituting y = v + 3, we have dv/dt = [tex]t^2 + (v+3)^2[/tex]. To shift the initial point to the origin, we set v(0) = y(0) - 3 = 3 - 3 = 0.

By introducing these new variables and adjusting the initial conditions accordingly, we can transform the given initial value problems into equivalent ones with the initial point at the origin.

The length of the diagonal of the square is 9√2 centimeters.

The height of the isosceles triangle is 5√15 centimeters.

To find the length of the diagonal of a square, we can use the formula for the diagonal (d) in terms of the side length (s):

d = s√2

Given that the area of the square is 81 square centimeters, we can find the side length (s) by taking the square root of the area:

s = √81

s = 9 cm

Now, we can find the length of the diagonal (d):

d = s√2

d = 9√2 cm

Therefore, the length of the diagonal of the square is 9√2 centimeters.

Now let's move on to the second part of the question:

An isosceles triangle has congruent sides of 20 cm, and the base is 10 cm.

To find the height of the triangle, we can use the Pythagorean theorem.

The height (h) of the isosceles triangle divides the base into two equal segments, each with a length of 5 cm.

Using the Pythagorean theorem, we can set up the equation:

h^2 + 5^2 = 20^2

h^2 + 25 = 400

h^2 = 400 - 25

h^2 = 375

Taking the square root of both sides:

h = √375

Since 375 can be simplified by factoring out the perfect square of 25, we have:

h = √(25 * 15)

h = 5√15 cm

Therefore, the height of the isosceles triangle is 5√15 centimeters.

The function has a local minimum at x = 3 with a value of -104 and a local maximum at x = 9 with a value of 250.

To find the local minimum and local maximum of the function, we need to analyze its critical points and the behavior of the function around those points.

First, we find the derivative of f(x):

f'(x) = -6x^2 + 66x - 108.

Next, we set f'(x) equal to zero and solve for x to find the critical points:

-6x^2 + 66x - 108 = 0.

Dividing the equation by -6 gives:

x^2 - 11x + 18 = 0.

Factoring the quadratic equation, we have:

(x - 2)(x - 9) = 0.

From this, we can see that x = 2 and x = 9 are the critical points.

To determine whether each critical point is a local minimum or local maximum, we need to analyze the behavior of f'(x) around these points. We can do this by evaluating the second derivative of f(x):

f''(x) = -12x + 66.

Evaluating f''(2), we have:

f''(2) = -12(2) + 66 = 42.

Since f''(2) is positive, we can conclude that x = 2 is a local minimum.

Evaluating f''(9), we have:

f''(9) = -12(9) + 66 = -6.

Since f''(9) is negative, we can conclude that x = 9 is a local maximum.

Therefore, the function f(x) has a local minimum at x = 2 with a value of -104 and a local maximum at x = 9 with a value of 250.
