Answer: (C) \(y+1=-2(x-2)\)

Step-by-step explanation:

Slope: y = mx +b

By looking at the graph we can see that the slope has a rise of 2 and a run of -1 (aka. -2x) We can also tell that this has a y-intercept of 3

So our slope is: y = -2x + 3

Now you just have to find the answer that matches.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

\(y = 8 - x\)

\(y = - x + 8\)

\(y = - 1x + 8\)

\(Slope = coefficient \: \: of \: \: x \)

Thus :

\(Slope = - 1\)

The percentage increase per year in the winner's check over the given period. If the winner's prize increases at the same rate, it will be $1,454,735,139.69 in 2040.

To calculate the percentage increase per year in the winner's check over the period from 1895 to 2007, we can use the following formula:

Percentage Increase = (Final Value - Initial Value) / Initial Value * 100

a. Calculating the percentage increase:

Initial Value = $140

Final Value = $1,171,000

Percentage Increase = (1,171,000 - 140) / 140 * 100 ≈ 835,714.29%

b. To estimate the winner's prize in 2040, we can assume the same annual percentage increase will continue. We need to calculate the number of years from 2007 to 2040 and apply the percentage increase to the 2007 prize.

Number of years = 2040 - 2007 = 33 years

Estimated prize in 2040 = 1,171,000 * (1 + (Percentage Increase / 100))^33

Estimated prize in 2040 = 1,171,000 * (1 + (835,714.29 / 100))^33 ≈ $1,454,735,139.69

Therefore, if the winner's prize increases at the same rate, it is estimated to be approximately $1,454,735,139.69 in 2040.

The two equations would be 1.5x + 2.5y = 30, 3x + 1.5y = 40, when we add both the equations we get, 4.5x + 4y = 70, and the value of x is 10.

To solve a system of linear equations in two variables using the substitution in two variables using the substitution method. First solve one of the equations for one variable. Substitute this in the other equation in terms of a single variable. Then solve it for the variable. Now, substitute it in any of the equations to get the value of another variable.

Given:

Add the two equations together:

1.5x + 2.5y = 30

3x + 1.5y = 40

(1.5x + 3x) + (2.5y + 1.5y) = (30 + 40)

4.5x + 4y = 70

Isolate the x-variable by subtracting 4y from both sides of the equation:

4.5x + 4y = 70

4.5x + 4y - 4y = 70 - 4y

4.5x = 70 - 4y

Divide both sides of the equation by 4.5 to solve for x:

4.5x = 70 - 4y

4.5x/ 4.5 = (70 - 4y)/4.5

x = (70 - 4y) / 4.5

Substitute the value of y from the first equation:

1.5x + 2.5y = 30

2.5y = 30 - 1.5x

y = (30 - 1.5x) / 2.5

Substitute the value of y into the equation for x and solve:

x = (70 - 4y) / 4.5

x = (70 - 4((30 - 1.5x) / 2.5)) / 4.5

x = 10

The marginal propensity to save when x = 3 is approximately 0.651.

To find the marginal propensity to save (dx) for the given consumption function C(x) = 0.774 \(x^1^.^1\) + 26.9 billion per billion dollars when x = 3:

To find the marginal propensity to save, we need to differentiate the consumption function C(x) with respect to x and evaluate it at x = 3.

Taking the derivative of C(x) = 0.774 \(x^1^.^1\)  + 26.9 with respect to x, we get:

dC/dx = 0.774 * 1.1 * \(x^1^.^1^-^1\) = 0.8514\(x^0^.^1\)

Now, we evaluate the derivative at x = 3:

dC/dx = 0.8514 * \(3^0^.^1\)= 0.6507 (rounded to three decimal places)

Therefore, the marginal propensity to save when x = 3 is approximately 0.651. This value represents the rate of change of savings with respect to a change in income, indicating the proportion of additional income saved in the economy at that specific level of income.

he required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Let’s assume the general solution of the given differential equation is,

y=e^{mx}

By taking the derivative of this equation, we get

\(\frac{dy}{dx} = me^{mx}\\\frac{d^2y}{dx^2} = m^2e^{mx}\\\frac{d^3y}{dx^3} = m^3e^{mx}\\\frac{d^4y}{dx^4} = m^4e^{mx}\\\)

Now substitute these values in the given differential equation.

\(\frac{d^4y}{dx^4}-2\frac{d^2y}{dx^2}-8y\\=0m^4e^{mx}-2m^2e^{mx}-8e^{mx}\\=0e^{mx}(m^4-2m^2-8)=0\)

Therefore, \(m^4-2m^2-8=0\)

\((m^2-4)(m^2+2)=0\)

Therefore, the roots are, \(m = ±\sqrt{2} and m=±2\)

By applying the formula for the general solution of a differential equation, we get

General solution is, \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

Hence, the required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

The graph that represents the situation is required.

What is graph?

A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Graphs are a popular tool for graphically illuminating data connections. A graph serves the objective of presenting facts that are either too many or complex to be fully expressed in the text while taking up less room.

Answer:

C. 33.

Step-by-step explanation:

The sides of a 45-45-90 triangle are in the ratio 1:1:√2 so the side opposite to 45 degrees = 11√6 / √2.

Consider the larger triangle containing the 60 degree angle:

tan 60 = x / (11√6 / √2).

x = tan 60 * 11√6 / √2

x = 33.

The value of the variable x will be 33 units. Then the correct option is C.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The diagram is shown below.

Let h be the height of the triangle.

The value of h is given by the sine of angle 45°. Then the value of the height h will be

sin 45° = h / 11√6

h = 11√6 × 1/√2

h = 11√3 units

The value of h is given by the tangent of angle 60°. Then the value of the height h will be

tan 60° = x / h

x = 11√3 × √3

x = 11 × 3

x = 33 units

Thus, the value of the variable x will be 33 units.

An orthogonal set with the same dimension as the initial collection of vectors is created by the Gram-Schmidt process.

Given that,

From a linearly independent collection of {x₁, x₂,..., xp}, the gram-Schmidt process creates an orthogonal set of {v₁, v₂,..., vp} with the feature that for each k, the vectors v₁...vk span the same subspace as that spanned by x₁...xk.

Whether the claim is true or false must be determined.

The statement is true.

An orthogonal set with the same dimension as the initial collection of vectors is created by the Gram-Schmidt process. An orthogonal set is further linearly independent.

From the information, the model car is constructed with a scale of 1:15.

When the actual car is 12 feet long, the length of the model will be illustrated as x. This will be:

The proportion allows us to relate the length of AC to the circumference of a circle and the angle subtended by AC.

The given proportion is (x/12π) = (130/360).

This proportion can be used to solve for the length of AC in the given context.

The length of AC is represented by x.

The proportion compares the length of AC (x) to the circumference of a circle with a radius of 12.

In the equation, the left-hand side represents the ratio of the length of AC to the circumference of the circle.

Since the circumference of a circle is given by the formula 2πr, where r is the radius, the length of AC is divided by 12π to represent the proportionate length relative to the circle's circumference.

On the right-hand side, we have the ratio 130/360. This ratio represents the proportion of a complete circle (360 degrees) that corresponds to the angle subtended by AC. The length of AC is compared to a fraction of the entire circle.

To solve the proportion, we can cross-multiply and then solve for x:

x (360) = 12π(130).

By simplifying the equation and solving for x, we can find the length of AC.

In summary, the given proportion allows us to relate the length of AC to the circumference of a circle and the angle subtended by AC.
