To calculate the exponential smoothing forecast for May, we need to use the formula Therefore the correct option is A 51.60 .
[tex]Ft = alpha * Xt + (1 - alpha) * Ft-1[/tex] Where: - Ft is the forecast for time period t - Xt is the actual sales for time period t - Ft-1 is the forecast for the previous time period (t-1) - alpha is the smoothing constant Given that the forecast for January is 50, we can calculate the forecast for February as follows: [tex]F1 = 0.30 * 50 + (1 - 0.30) * 50 = 50[/tex] Similarly, we can calculate
the forecasts for March and April: F2 [tex]= 0.30 * 80 + (1 - 0.30) * 50 = 65[/tex] F3 [tex]= 0.30 * 70 + (1 - 0.30) * 65 = 66.50[/tex] F4 [tex]= 0.30 * 60 + (1 - 0.30) * 66.50 = 63.05[/tex] Now, to calculate the forecast for May: F5 [tex]= 0.30 * Xt-1 + (1 - 0.30) * Ft-1 F5 = 0.30 * 60 + (1 - 0.30) * 63.05 F5 ≈ 51.60[/tex] Therefore, the forecast for May using exponential smoothing with a smoothing constant of 0.30 is approximately 51.60 (option a).
Hence the correct option is A

5. Open Response Monique wants to rent
online movies. Movies Plus charges a
one-time fee of $20 plus $5 per movie.
Movies-To-Go charges $7 per movie. For how
many movies is the cost of renting movies
from Movies Plus and Movies-To-Go the
same?
Answer:
I'm going to say Movies-To-Go because this is an easy question.
Step-by-step explanation:
movies plus charges more than movies to go and your asking for which one is cheaper so movies to go is the answer.
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is 10 movies.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Movies plus:
One time fee = $20
Cost per movie = $5
We can write an equation for the total cost T for x movies:
T = 20 + 5x _____(1)
Movie-to-go:
Cost per movie = $7
We can write an equation for the total cost T for x movies:
T = 7x _____(2)
Now,
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is:
From (1) and (2),
20 + 5x = 7x
20 = 7x - 5x
20 = 2x
x = 20/2
x = 10
Thus,
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is 10 movies.

The equation of the piecewise defined function f(x) is below. What is the value of f(1)?
The value of the f(1) should be -1 when the equation of the piecewise defined function f(x).
Calculation of the value of f(1):here first we are required to determine which expression to use for f(1). The first function does not involve 1, because it is <, and not ≤
And,
The second functions involved 1, because it has a ≤ that meaning greater than or equal to, so this is the function we must use.
So, it can be like
f(1) = -1
= -(x^2)
= -(1)
= -1
hence,
The value of the f(1) should be -1 when the equation of the piecewise defined function f(x).

Answer:
I assume that the figure your figure is like this:
The Area of the shaded Region is 36π .
What is a Circle ?A circle is a round shaped figure whose all the point lie in the same plane.
It is given that Area of the shaded region needs to be found in the figure attached
Radius of the outer circle is 10
and Radius of the inner circle is 8
The area of the shaded region = Area of the outer circle - area of the inner circle
Area of a circle = πr²
r is the radius of the circle.
Area of the outer circle = π(10)²
Area of the outer circle = 100π
Area of the inner circle = π (8)²
Area of the inner circle = 64 π
Area of the shaded Region = 100π - 64 π
Area of the shaded Region = 36π
Therefore the Area of the shaded Region is 36π .

Work Shown:
Plug (x,y) = (3,2) into the F(x,y) function
[tex]F(x,y) = 2x^2 + 4y^2\\\\F(3,2) = 2(3)^2 + 4(2)^2\\\\F(3,2) = 34\\\\[/tex]
Next, find the gradient and plug in (x,y) = (3,2)
[tex]F(x,y) = 2x^2 + 4y^2\\\\\\\nabla F(x,y) = \Big< \frac{dF}{dx}, \frac{dF}{dy}\Big>\\\\\\\nabla F(x,y) = \Big< 4x, 8y \Big>\\\\\\\nabla F(3,2) = \Big< 4*3, 8*2 \Big>\\\\\\\nabla F(3,2) = \Big< 12, 16 \Big>\\\\\\[/tex]
This means,
[tex]z = \nabla F(3,2) \cdot \left(\vec{x} - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \left(\big< x,y \big> - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \big< x-3,y-2 \big> + F(3,2)\\\\\\z = \big< 12,16 \big> \cdot \big< x-3,y-2 \big> + 34\\\\\\z = 12(x-3)+16(y-2) + 34\\\\\\z = 12x-36+16y-32 + 34\\\\\\z = 12x+16y-34\\\\\\[/tex]
As a way to help check, note how plugging (x,y) = (3,2) into the last equation for z leads to z = 34. This helps confirm that we have the correct equation because the point (3,2,34) must be on F(x,y) and also on z since the plane is tangent to the F(x,y) curve at this point.
