The general solution to the given equation is:

y = c₁ * e⁻²ˣ + c₂ * e⁻ˣ - eˣ - 2xe⁻ˣ

where c₁ and c₂ are arbitrary constants.

To solve the equation y'' + 3y' + 2y = xe³ˣ, we first need to find a fundamental set of solutions for the homogeneous equation y'' + 3y' + 2y = 0.

The characteristic equation for the homogeneous equation is:

r² + 3r + 2 = 0

Factoring the equation, we get:

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

This gives us two distinct roots: r = -2 and r = -1.

Therefore, the fundamental set of solutions for the homogeneous equation is:

y₁(x) = e⁻²ˣ

y₂(x) = e⁻ˣ

Next, we need to find the Wronskian determinant, W, and its derivatives, W₁ and W₂.

W = det([y₁(x), y₂(x); y₁'(x), y₂'(x)])

  = det([e⁻²ˣ, e⁻ˣ; -2e⁻²ˣ, -e⁻ˣ])

  = -e⁻³ˣ

W₁ = det([0, e⁻ˣ; -2e⁻²ˣ, -e⁻ˣ])

   = 2e⁻ˣ

W₂ = det([e⁻²ˣ, 0; -2e⁻²ˣ, -2e⁻ˣ])

   = -2e⁻³ˣ

Now, we can find the particular solution, y_p, using the formulas:

u₁ = ∫(W₁' / W₁) dx

u₂ = ∫(W₂' / W₂) dx

Let's compute these integrals:

u₁ = ∫((2e⁻ˣ) / (-e⁻³ˣ)) dx

    = -2 ∫ e²ˣ dx

    = -e²ˣ

u₂ = ∫((-2e⁻³ˣ) / (-e⁻³ˣ)) dx

    = -2 ∫ dx

    = -2x

Now, we can find the particular solution, y_p, using the formula:

y_p = u₁ * y₁ + u₂ * y₂

y_p = (-e²ˣ) * e⁻²ˣ + (-2x) * e⁻ˣ

   = -eˣ - 2xe⁻ˣ

Finally, the general solution to the given equation is:

y = c₁ * y₁ + c₂ * y₂ + y_p

  = c₁ * e⁻²ˣ + c₂ * e⁻ˣ - eˣ - 2xe⁻ˣ

where c₁ and c₂ are arbitrary constants.

At 5% rate the account been earning interest.

Given that Ruby has saved $4072.24, and she initially invested $2500, we can plug in these values into the formula:

4072.24 = 2500(1 + r/1\()^{(1 )(10)\)

Simplifying the equation, we get:

(1 + r)¹⁰ = 4072.24/2500

Taking the 10th root of both sides, we have:

1 + r = (4072.24/2500\()^{(1/10)\)

Subtracting 1 from both sides, we find:

r = (4072.24/2500\()^{(1/10)\)- 1

The Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.

Exponential smoothing is a forecasting technique that takes into account both the historical demand and the trend of the data. It is calculated using the formula:

Forecast = α * (Demand / Seasonal Index) + (1 - α) * Previous Forecast

Initial forecast (Previous Forecast) = 417

α (Smoothing parameter) = 0.35

Demand for Year 4, Q1 = 307

Seasonal Index for Q1 = 0.762

Using the formula, we can calculate the Year 4, Q1 forecast:

Forecast = 0.35 * (307 / 0.762) + (1 - 0.35) * 417

        = 335.88

Therefore, the Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.

The forecasted demand for Year 4, Q1 using exponential smoothing is 335.88.

When a 10% increase in income causes a 4% increase in quantity demanded of a good is income inelastic.

More specifically, the income elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in income. In this case, we have:

Income elasticity of demand = (% change in quantity demanded) / (% change in income)

= 4% / 10%

= 0.4

Since the income elasticity of demand is less than one, we say that the good is income inelastic. we can say that the income elasticity of demand for the good is positive and less than one. This means that the quantity demanded of the good does not increase proportionally as income increases. Instead, the increase in quantity demanded is less than the increase in income.

True, to calculate the average of numeric values in the list, the first step is to get the total of values in the list.

Steps to calculate the Average:

Let’s assume there are 4 numbers having values of 2,8,22,48 respectively.

To find the average we first have to take the total of all values.

2+8+22+48=80.

Our next step will be to divide this total by the number we have in our question i.e., 4.

so, our average will be 80/4= 20.

So, 20 will be our average.

In the object-oriented programming paradigm, a class invariant is a property that must always be true for any instance of a class. It is a condition or a set of conditions that must be maintained by all member functions for the proper functioning of a class.

A class invariant, therefore, is a formal statement of the rules that dictate how the member variables of a class are used. All member functions (with the exception of constructors) can depend on the invariant being valid when the function is called. Each function is also responsible for ensuring that the invariant is valid when the function finishes.

The invariant represents an important constraint that must be maintained in a class. As a result, a well-defined class invariant is important for the stability and reliability of the class.

The class invariant may be a single condition or a set of conditions that need to be maintained for the class to operate correctly. These conditions may be explicitly stated in the class documentation or in the form of assert statements in the class implementation. The invariant may be as simple as a range constraint or as complex as a logical relationship between multiple variables.

In any case, the invariant must be maintained by all the member functions of the class. the invariant of a class is a set of rules that govern how the member variables of a class are used.

Step-by-step explanation:

To determine the values of "c" for the given functions to represent joint probability distributions of random variables X and Y, we need to ensure that the probabilities sum up to 1 and that the function satisfies all the properties of a probability distribution.

(a) For the function f(x, y) = cxy, where x = 1, 2, 3 and y = 1, 2, 3:

To find the value of "c," we need to calculate the sum of all probabilities and set it equal to 1:

∑∑ f(x, y) = c∑∑ xy = c(1 + 2 + 3) (1 + 2 + 3) = c(6)(6) = 36c

For this function to represent a joint probability distribution, the sum of all probabilities must be 1. Therefore, we have:

36c = 1

c = 1/36

So, the value of "c" for this function is 1/36.

(b) For the function f(x, y) = c |x - y|, where x = -2, 0, 2 and y = -2, 3:

Using the same approach, we calculate the sum of probabilities and set it equal to 1:

∑∑ f(x, y) = c∑∑ |x - y| = c[|-2 - (-2)| + |0 - (-2)| + |2 - (-2)| + |(-2) - 3| + |0 - 3| + |2 - 3|]

= c[0 + 2 + 4 + 5 + 3 + 1]

= c(15)

For this function to represent a joint probability distribution, the sum of all probabilities must be 1. Therefore, we have:

15c = 1

c = 1/15

So, the value of "c" for this function is 1/15.

In summary, for the functions f(x, y) = cxy and f(x, y) = c |x - y| to represent joint probability distributions, the values of "c" are 1/36 and 1/15, respectively.

This result indicates that the side length of the white square is 0. The area of one of the white squares can be determined by subtracting the area of the green border from the total area of each face of the cube.

The total area of each face of the cube is given by the formula: side length * side length.

Given that the edge of the cube is 10 feet, the total area of each face is:

Area of each face = 10 feet * 10 feet = 100 square feet

Now, let's consider the green border. Since each face has a white square centered on it, the dimensions of the white square will be smaller than the face itself.

Let's assume the side length of the white square is "x" feet. This means that the side length of the green border is (10 - x) / 2 feet on each side.

The area of the green border on each face is then:

Area of green border = (10 - x) / 2 * (10 - x) / 2 = (10 - x)^2 / 4 square feet

To find the area of the white square, we subtract the area of the green border from the total area of each face:

Area of white square = Area of each face - Area of green border

= 100 square feet - (10 - x)^2 / 4 square feet

Given that Marla has enough green paint to cover 300 square feet, we can set up the equation:

Area of white square * 6 (number of faces) = 300 square feet

(100 - (10 - x)^2 / 4) * 6 = 300

Now we can solve for x:

100 - (10 - x)^2 / 4 = 50

100 - (10 - x)^2 = 200

(10 - x)^2 = 100

Taking the square root of both sides:

10 - x = 10

x = 0

This result indicates that the side length of the white square is 0, which doesn't make sense in this context. It seems there might be an error or inconsistency in the given information or calculations.
