The general solution to the given system of differential equations is:

x(t) = c1 + c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2)

y(t) = c1 + c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2)

where c1, c2, and c3 are constants determined by initial conditions or specific constraints.

To solve the system using the elimination method, we need to eliminate one variable at a time. Let's start by eliminating x.

x' = x - y ...........(1)

y'' = -2x' + e^t ...........(2)

First, differentiate equation (1) with respect to t to get:

x'' = x' - y' ...........(3)

Now substitute the value of x' from equation (3) into equation (2):

y'' = -2(x' - y) + e^t

y'' = -2x' + 2y + e^t ...........(4)

To eliminate x', we subtract equation (4) from equation (2):

y'' - y' = e^t ...........(5)

Next, differentiate equation (5) with respect to t:

y''' - y'' = e^t ...........(6)

Now we have two equations:

y'' - y' = e^t ...........(5)

y''' - y'' = e^t ...........(6)

To solve these equations, we can solve equation (6) for y'' and substitute it into equation (5):

(y''' - e^t) - (y'' - y') = e^t

y''' - y'' + y' - e^t = e^t

y''' - y'' + y' = 2e^t ...........(7)

Equation (7) is a third-order linear homogeneous differential equation for y.

To find the general solution to equation (7), we solve its characteristic equation:

r^3 - r^2 + r = 0

Factoring out an r, we get:

r(r^2 - r + 1) = 0

This equation has one real root r = 0 and two complex roots r = (1 ± √3i)/2.

Therefore, the general solution for y is:

y(t) = c1 + c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2)

Now, we can substitute the general solution for y into equation (5) to solve for x:

y'' - y' = e^t

(c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2))' - (c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2)) = e^t

Differentiating and simplifying, we get:

(-c2e^t(√3/2)sin((√3t)/2) + c3e^t(√3/2)cos((√3t)/2)) - (c2e^tcos((√3t)/2) + c3e^tsin((√3t)/2)) = e^t

Simplifying further, we get:

(-c2e^t(√3/2)sin((√3t)/2) + c3e^t(√3/2)cos((√3t)/2)) - c2e^tcos((√3t)/2) - c3e^tsin((√3t)/2) = e^t

Now, equating the coefficients of e^t and the trigonometric terms, we can solve for c1, c2, and c3.

This completes the solution process using the elimination method for the given system of differential equations.

a) John withdraws $1,300.

b) The annual effective yield rate for John's six-year investment is 2.09%.

a) To find the amount that John withdraws, we need to calculate the future value of his deposits after six years.

For the first three years, the deposits gain interest at a force of interest of 0.06. So after three years, the balance becomes $500 * (1 + 0.06)^3 = $595.44.

After three years, the interest rate changes to an effective rate of discount of 8%. Using the formula for the future value of a single sum with a discount rate, we can calculate the balance after six years:

$595.44 * (1 - 0.08)^3 = $429.97.

Therefore, John withdraws $429.97.

b) The annual effective yield rate can be found by calculating the rate of return on John's initial deposit over six years.

Let's assume John's initial deposit is $D. After three years, it grows to $D * (1 + 0.06)^3 = $1.191D. After six years, it becomes $1.191D * (1 - 0.08)^3 = $0.924D.

To find the annual effective yield rate, we need to solve the equation:

$D * (1 + r)^6 = $0.924D,

where r is the annual effective yield rate.

Simplifying the equation:

(1 + r)^6 = 0.924,

Taking the sixth root of both sides:

1 + r = 0.924^(1/6),

r = 0.0209.

Therefore, the annual effective yield rate for John's six-year investment is 2.09%.

The approximately 59.90 percent of the observations differ from the mean by less than 0.56o.

The standard deviation is a measure of the amount of variation or dispersion in a set of observations.

For a normal distribution, it is straightforward to determine the proportion of values that are more than a certain number of standard deviations above or below the mean.

Here's how to determine the percentage of observations that differ from the mean by more than 2.50 or less than 0.56o in a normally distributed set of observations.

Solution:

(a)  The percentage of observations that differ from the mean by more than 2.50 is given by the formula below:P(Z > 2.50) + P(Z < -2.50) = 0.00621 + 0.00621 = 0.0124

To obtain the proportion in percentage, multiply by 100: 0.0124 * 100 = 1.24%.

Therefore, about 1.24 percent of the observations differ from the mean by more than 2.50.

(b) The proportion of observations that differ from the mean by less than 0.56o is given by:

P(-0.56/σ < Z < 0.56/σ) = P(Z < 0.84) − P(Z < -0.84) = 0.7995 - 0.2005 = 0.5990

To obtain the proportion in percentage, multiply by 100: 0.5990 * 100 = 59.90%.

To represent this situation, we can use the following equation:x = the number of packs of stickers Isabella bought x packs of stickers, and each pack costs $3.

So the total cost of the stickers is given by the following equation:3x = total cost of stickers Since she spent a total of $18 on stickers, we can set the equation equal to 18 to get:3x = 183x/3 = 18/3x = 6Therefore, Isabella bought 6 packs of stickers to give to her friends.

To solve this problem, let's assume that Isabella bought "x" packs of stickers.

According to the given information, each pack costs $3. So, the total amount Isabella spent on stickers is $18.

We can represent this situation with the following equation:

3x = 18

Here, "3x" represents the cost of "x" packs of stickers, and it is equal to $18.

To find the number of packs Isabella bought, we can solve the equation for "x".

Dividing both sides of the equation by 3, we get:

x = 18 / 3

x = 6

Therefore, Isabella bought 6 packs of stickers.

Answer:

The first option.

Step-by-step explanation:

Add all the numbers together and voila you get 27

(a) The Y-intercept, bo = 6, implies that when the value of X is 0, the mean value of Y is 6.

(b) The slope, by = 4, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 4 units.

(c) The mean value of Y for X = 4 is predicted to be 22.

The Y-intercept, bo, represents the starting point of the prediction line. In this case, when X is 0, the mean value of Y is expected to be 6. This implies that before any increase or decrease in X, the average value of Y starts at 6.

The slope, by = 4, indicates the rate at which Y is expected to change for each unit increase in X. Therefore, for every 1 unit increase in X, the value of Y is expected to increase by 4 units. This implies a linear relationship between X and Y, where the increase or decrease in X directly influences the corresponding change in Y.

To predict the mean value of Y for X = 4, we can use the prediction line equation: Y = 6 + 4x. Substituting X = 4 into the equation, we get: Y = 6 + 4(4) = 6 + 16 = 22. Therefore, the mean value of Y for X = 4 is predicted to be 22.

Step-by-step explanation:

Given a 3x3 matrix A with eigenvalues -1 and 3, and corresponding eigenvectors V1 = [-1, 3, -1] and V2 = [0, 2, 3], we can determine various products and properties of the matrix A.

(a) To find the product Av2, we simply multiply the matrix A by the vector V2. The resulting product is [0, 2, 10].

(b) To find the product A(3v1 - v3), we first calculate 3v1 - v3, which is equal to [-4, -10, 6]. Then, we multiply the matrix A by this vector to obtain the product [-4, -10, 10].

(c) Two eigenvectors corresponding to the eigenvalue -1 can be identified as V1 = [-1, 3, -1] and any scalar multiple of V1, such as [2, -6, 2].

(d) To determine if A is diagonalizable, we check if it has three linearly independent eigenvectors. In this case, A has two distinct eigenvalues (-1 and 3), and we are given that the eigenspace corresponding to each eigenvalue has a basis with two vectors in total. Since the sum of the dimensions of the eigenspaces is equal to the dimension of A (3), A is diagonalizable.

To diagonalize A, we construct a matrix P with the eigenvectors as its columns. We have P = [V1, V2, V3] = [-1, 0, 2; 3, 2, -6; -1, 3, 2]. Then, we calculate P-1 and find D, the diagonal matrix of eigenvalues: D = diag(-1, 3). Finally, we obtain the diagonalized form P-1AP = D, where P-1 is the inverse of matrix P.
