3 Answers: Choice A, Choice B, Choice E

=========================================================

Explanation:

We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.

Also, the other terms add to 15+5+15+5 = 20+20 = 40

Therefore, we end up with 4x+40 from choice A.

-----------------------------

Once we get to 4x+40, we can factor out 2 from it like so

4x+40

2*2x + 2*20

2(2x+20) which is choice B

I used the distributive property to factor. That rule is a(b+c) = ab + ac

-------------------------------

Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.

Choice D is a similar story to choice C.

--------------------------------

Choice E is another answer

This is because we have two copies of (x+15), so that gives 2(x+15)

The frequency with the largest amplitude is `w ≈ 2.303` (rtol=0.01, atol=1e-08).

The question asks us to find the frequency w for which the particular solution to the differential equation \(dạy dy 2- + dt2 + 2y = eiwt dt\)has the largest amplitude.

We can assume a positive frequency w > 0.

Let's find out how to solve this problem:

We need to find the particular solution in the form Aeiwt, and then minimize the modulus of the denominator of A over all frequencies w. It means the denominator of A will have a maximum amplitude if we minimize the modulus. The amplitude of the solution is given by the value of |A|.

Let us assume the particular solution to be `\(y = Aeiwt`.\)

Substitute the above solution in the given differential equation.

Then, we get:\(`d^2(A e^(iwt))/dt^2 + 2(A e^(iwt)) = e^(iwt)`\)Applying the differential operator on the above equation,

we get: \(`(iwt)^2 A e^(iwt) + 2A e^(iwt) = e^(iwt)`Therefore, `A = 1 / (1 - (w^2) + 2i)`.\)

Thus, the amplitude of the particular solution is:

\(`|A| = 1 / sqrt((1 - w^2)^2 + 4w^2)`\)

Now, we need to minimize the above expression to get the frequency w at which the amplitude of the particular solution is maximum. This can be done by minimizing the modulus of the denominator of A over all frequencies w.To minimize the above expression, we take the derivative of the expression with respect to w and equate it to zero, which gives us: \(`(8w^2) / ((w^2 - 1)^2 + 4w^2)^(3/2) - (2(w^2 - 1)) / ((w^2 - 1)^2 + 4w^2)^(3/2) = 0`\)

Simplifying the above expression, we get: `

\(2w^2 = w^4 - 3w^2 + 1`\)

Therefore, \(`w^4 - 5w^2 + 1 = 0`.\)

Solving the above equation gives us:

`\(w^2 = (5 ± sqrt(21)) / 2`\).Since we know that w > 0, we choose the positive value of w.

Thus, the value of w is: \(`w = sqrt((5 + sqrt(21)) / 2)` or `w ≈ 2.303\)`.

by strong induction, we can form any amount of money that is a multiple of $2$ greater than or equal to $2$.To prove this using strong induction, we need to show two things:

1. That we can form the amounts $2$ and $5$ using just $2$-dollar bills and $5$-dollar bills.
2. That if we can form any amount $n$ using just $2$-dollar bills and $5$-dollar bills, we can also form the amount $n+2$.

For the base case, it's clear that we can form the amounts $2$ and $5$.

For the inductive step, assume that we can form any amount $k$ using just $2$-dollar bills and $5$-dollar bills, where $k \geq 5$. We want to show that we can also form the amount $k+2$.

There are two cases to consider:

1. If we have at least one $5$-dollar bill, then we can form the amount $(k+2)$ by adding a $5$-dollar bill to the amount $(k-3)$, which we know we can form using just $2$-dollar bills and $5$-dollar bills.
2. If we don't have any $5$-dollar bills, then we must have at least two $2$-dollar bills. We can form the amount $(k+2)$ by using one of the $2$-dollar bills to form the amount $(k-3)$, which we know we can form, and then adding three more $2$-dollar bills.

Therefore, by strong induction, we can form any amount of money that is a multiple of $2$ greater than or equal to $2$.

The next three successive approximations of the solution to the nonlinear problem y′(x).

To use Picard's method with φ0(x) ≡ 0, we can obtain the next three successive approximations of the solution to the nonlinear problem y′(x).

The Picard's method involves solving the differential equation iteratively by substituting the previous approximation into the equation to obtain a new approximation. In this case, the initial approximation φ0(x) ≡ 0 means that we start with a constant function equal to zero.

To obtain the first approximation, we substitute φ0(x) = 0 into the given nonlinear problem y′(x). This gives us a new equation y′(x) = 0.

Using this new equation, we can solve for the first approximation φ1(x). We integrate both sides of the equation with respect to x, giving us y(x) = c1, where c1 is an arbitrary constant.

For the second approximation φ2(x), we substitute φ1(x) = c1 into the nonlinear problem y′(x). Solving this equation will give us a new function φ2(x).

Similarly, for the third approximation φ3(x), we substitute φ2(x) into the nonlinear problem y′(x), and solve for φ3(x).

By repeating this process, we can obtain the next three successive approximations of the solution to the nonlinear problem y′(x). It is important to note that the accuracy of the approximations increases with each iteration, but the method may not always converge to the exact solution.

To estimate the volume of a region rotated about the y-axis using the midpoint method, we need to divide the region into small vertical slices perpendicular to the y-axis.

By approximating each slice as a cylinder with a height equal to the width of the slice and a radius equal to the midpoint of the slice, we can calculate the volume of each slice. Summing up the volumes of all the slices will give us an estimate of the total volume.

To use the midpoint method, we first divide the region into small vertical slices along the y-axis. Each slice is perpendicular to the y-axis and has a width equal to the thickness of the slice. The midpoint of each slice represents the radius of the corresponding cylinder.

By considering the height of each slice as the width of the slice, we can approximate each slice as a cylinder. The volume of each cylinder is calculated using the formula V = πr²h, where r is the radius and h is the height. Adding up the volumes of all the cylinders or slices will provide an estimate of the total volume of the region rotated about the y-axis using the midpoint method.

The order (p) of an autoregressive (AR) process can be determined by Durbin-Watson Statistic, Box-Pierce Chi-square Statistic, Autocorrelation Function (ACF), and Partial Autocorrelation Function (PACF) coefficients., option E is correct.

The Durbin-Watson statistic is used to test for the presence of autocorrelation in the residuals of a time series model.

It can provide an indication of the order of the AR process if it shows significant autocorrelation at certain lags.

The Box-Pierce test is a statistical test used to assess the goodness-of-fit of a time series model.

It examines the residuals for autocorrelation at different lags and can help determine the appropriate order of the AR process.

Autocorrelation Function (ACF): The ACF is a plot of the correlation between a time series and its lagged values. By analyzing the ACF plot, one can observe the significant autocorrelation at certain lags, which can suggest the order of the AR process.

The PACF measures the direct relationship between a time series and its lagged values after removing the effects of intermediate lags.

Significant coefficients in the PACF plot at certain lags can indicate the appropriate order of the AR process.

By considering all of these methods together and analyzing their results, one can make a more informed decision about the order (p) of an autoregressive (AR) process.

Jon and Jim together painted 2/3 of the fence.

To find the total amount of the fence that Jon and Jim painted, we need to add the fractions representing the portions they each painted.

Jon painted one quarter of the fence, which can be written as 1/4.

Jim painted five twelfths of the fence, which can be written as 5/12.

To add these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 4 and 12. In this case, the LCM is 12.

Now, let's rewrite the fractions with a common denominator of 12:

Jon's portion: (1/4) × (3/3) = 3/12

Jim's portion: (5/12)

Adding these fractions together:

Total portion = Jon's portion + Jim's portion = 3/12 + 5/12 = 8/12

The fraction 8/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

Total portion = (8/4) / (12/4) = 2/3

Therefore, Jon and Jim together painted 2/3 of the fence.
