Step-by-step explanation:

Seven more than twice a number is 47. Let's break down this sentence into numbers so you can see what's going on.

"Seven more than twice a number" - This tells you that there is a number, let's call it y, that is 7 more than twice a different number, lets call this x. So in equation form this is y = 7 + 2x. Hmm this seems a little tricky, how do we find the answer? Well if we keep reading, it tells you that the number that is 7 more than twice another number is 47, so we now know that y = 47. So let's redo our equation by substituting y for the number 47:

47 = 7 + 2x

Now we have a workable equation. We need to solve for x. So let's rewrite this equation without changing it, just putting it in different order. Now we have 2x + 7 = 47. So how do we solve for x? First, we subtract 7 from both sides. Remember, when solving for x, anything you do to one side you must do to the other. So now we get this:

2x + 7 = 47 simplifies to 2x = 40

Now if we divide both sides by 2 to get x all by itself, we get x = 20. That is your answer. You can check it by substituting 20 for s in your original equation of 2x + 7 = 47, then you get 2(20) + 7 = 47. It works! Hope this helps!

The zeros of g(x) = f(x - 5) are -5, -2, and 2.

The related function, g(x) = f(x - 5), inherits the properties of the original function f(x) = x. Since f(x) = x is a linear function with a positive slope, it is always increasing.

When we shift f(x) five units to the right to obtain g(x) = f(x - 5), the function retains its increasing nature. However, the zeros of g(x) are affected by the transformation.

The zeros of f(x) = x are at x = 0, which means the x-intercept is (0, 0).

To find the zeros of g(x) = f(x - 5), we substitute x = 0 into g(x) and solve for x:

g(x) = f(x - 5)

g(0) = f(0 - 5)

g(0) = f(-5)

So, we need to find the value of f(-5). Since f(x) = x, we substitute x = -5 into f(x):

f(-5) = -5

Hence, the zero of g(x) = f(x - 5) is at x = -5, which means the x-intercept of g(x) is (-5, 0).

Therefore, the zeros of g(x) = f(x - 5) are -5, -2, and 2.

Additionally, since g(x) is a transformation of f(x), it inherits the decreasing nature when x < 0 from f(x). This means that for x values less than 0, the function g(x) decreases as x decreases.

The Mean Absolute Error (MAE) is [Insert value]. The Mean Squared Error (MSE) is [Insert value].

To calculate the Mean Absolute Error (MAE) and Mean Squared Error (MSE) using exponential smoothing, we need to find the optimum alpha value that minimizes the MSE. Excel Solver can be used to determine this value.

Organize the data: Arrange the given data in a column in Excel: 155, 145, 155, 162, 180, 165, 172, 149, 170, 172.

Set up the exponential smoothing model: Define the forecast for each period using the formula: Forecast = α * Actual + (1 - α) * Forecast(t-1)

Calculate the MAE and MSE: For each period, calculate the forecasted value using the exponential smoothing model. Then, calculate the absolute error by taking the absolute difference between the forecasted value and the actual value. Square each absolute error to obtain the squared error. Finally, calculate the average of the absolute errors to find the MAE and the average of the squared errors to find the MSE.

Use Excel Solver: To determine the optimum alpha value, you can set up Excel Solver to minimize the MSE by changing the alpha value. The objective is to find the alpha value that gives the lowest MSE.

After performing the calculations and using Excel Solver to find the optimum alpha value, you can obtain the Mean Absolute Error (MAE) and Mean Squared Error (MSE) for the given data. These values will provide a measure of the accuracy of the exponential smoothing forecast.

Step-by-step explanation:

sine typically intercept at (0,0)

cosine starts at an intercept on Y

The graphs of sine and cos trigonometric functions differ by the waves. The graphs are plotted.

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

A positive cosine trigonometric function graph starts at maximum value, descends to minimum value, and then rises back to maximum value.

When a graph is negative cosine, it starts at the minimum, climbs to the maximum, and then descends back to the minimum.

For a positive sine trigonometric function graph, the graph starts at the midline, rises to the maximum, descends to the midline again until it reaches the minimum, then rises to the midline again to finish.

In the case of a negative sine graph, the graph starts at the midline, descends to the minimum, then ascends to the midline once again until it reaches the maximum, before returning to the midline where it started.

Therefore, graphs of sine and cos differ with respects to wave formed.

W is the width

H is the height

Given

L = 10, W = 12 and H = 24

Surface area = 2(10)(12)+2(10)(24)+2(12)(24)

Surface area = 240+480+576

Surface area of the room = 1296ft²

If each ball in the room is 2.5in

Converting to inches to foot

1ft = 12in

xft = 2.5in

Cross multiply

x = 2.5/12

x = 0.2083ft

Diameter of the tennis ball is 0.2083ft

Total surface area of the ball = 4πr² or πd²

Total surface area of the ball = 3.14(0.2083)² = 0.1362ft²

Number of ball in the room = Total surface area of the room/Total surface area of the ball

The partial derivative of z with respect to w, z/w, is equal to zero for u = 3, v = 1, and w = 0.

.The partial derivative of z with respect to w, denoted as ∂z/∂w, can be found by differentiating z with respect to w while keeping all other variables constant.

∂z/∂w = 4x³w + 0 = 4x³w

To determine the value of ∂z/∂w when u = 3, v = 1, and w = 0, we need to substitute these values into the expression.

First, let's find the value of x using the given equation for y:

y = u + ve^w = 3 + 1e^0 = 4

Now, substituting x = uv⁴ + w⁴ and y = 4 into z:

z = x⁴ + xy³ = (uv⁴ + w⁴)⁴ + (uv⁴ + w⁴)(4)³

With the given values of u, v, and w, we have:

z = (3v⁴ + 0⁴)⁴ + (3v⁴ + 0⁴)(4)³ = (3v⁴)⁴ + (3v⁴)(4)³

Differentiating z with respect to w, while treating v as a constant, we obtain:

∂z/∂w = 4(3v⁴)³(0) = 0

Therefore, when u = 3, v = 1, and w = 0, the partial derivative of z with respect to w, ∂z/∂w, is equal to 0.

Rearranging:

-3x + y = -7      (B)

Multiply  B by 3:

Adding A and C:

-5x = -20

x = 4

Substitute for x in equation A:

4(4) - 3y = 1

3y = 15

y = 5.

To determine the elasticity, we need to differentiate both sides of the equation with respect to x and then multiply by (x/y):

Differentiating the equation with respect to x:

3.45 * d/dx(log(y)) = 87.6 * d/dx(log(x))

Using the property of logarithmic differentiation, we have:

3.45 * (1/y) * dy/dx = 87.6 * (1/x) * dx/dx

Simplifying and rearranging the equation:

(1/y) * dy/dx = (87.6/3.45) * (1/x)

(1/y) * dy/dx = 25.43/x

Multiplying both sides by (x/y):

dy/dx = (25.43/x) * (x/y)

dy/dx = 25.43/y

The elasticity is given by the ratio of the derivative of y with respect to x to the ratio of y to x. In this case, the elasticity is:

Elasticity = dy/dx * (x/y)

Substituting the value we obtained for dy/dx:

Elasticity = (25.43/y) * (x/y)

Elasticity = 25.43 * (x/y^2)

Therefore, the elasticity is given by 25.43 times the ratio of x to y squared.
