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.

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.

Step-by-step explanation:

I took the test on FLVS

The value of the f(1) should be -1 when the  equation of the piecewise defined function f(x).

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).

====================================================

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.

Answer:

In Phoenix they consume 60% more avocados than in Denver.

Step-by-step explanation:

Given that in Denver they consume 75 units of avocados, while in Phoenix they consume 120 units of said fruit, to determine the percentage difference between the consumption of both cities it is necessary to perform the following calculation:

75 = 100

120 = X

((120 x 100) / 75) = X

(12,000 / 75) = X

160 = X

160 - 100 = 60

Therefore, in Phoenix they consume 60% more avocados than in Denver.

In Phoenix they consume 60% more avocados than in Denver.

We have given that in Denver they consume 75 units of avocados, while in Phoenix they consume 120 units of said fruit, we have to determine the percentage difference between the consumption of both cities it is necessary to perform the following calculation

Suppose 75 = 100

[tex]120 = x[/tex]

[tex]100\times 120=75x[/tex]

divide both side by 75

[tex](120 \times 100) / 75) = X[/tex]

[tex](12,000 / 75) = X[/tex]

[tex]160 = X[/tex]

[tex]160 - 100 = 60[/tex]

Therefore, in Phoenix they consume 60% more avocados than in Denver.

I assume that the figure your figure is like this:

The Area of the shaded Region is 36π .

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 .
