\large\orange\implies \rm \large \:f(x) \:  =  \: 2x

We have to find x when f(x) is 8

\large\orange\implies \rm \large \:8 =  \: 2x

\large\orange\implies \rm \large \:  \cancel\frac{8}{2}  \:  =  \: x \\

\large\orange\implies \rm \large \: \: 4 \:  =  \: x

f(x) \: = \: 2x

We have to find x when f(x) is 8

8 = \: 2x

x = \frac{8}{2}  \\  \\ x = 1.

The value of x is 4 when f(x) is 8 .

UkoKoshka [18]

Answer:

f(x) = 1500x +3000

Step-by-step explanation:

Given

Represent the months with x and the earnings with y.

So:

(x_1,y_1) = (1,4500)

(x_2,y_2) = (2,6000)

Required

Determine the linear function

First, calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{6000 - 4500}{2 - 1}

m = \frac{1500}{1}

m = 1500

The equation is then calculated using:

y = m(x - x_1) + y_1

y = 1500(x - 1) + 4500

y = 1500x - 1500 + 4500

y = 1500x +3000

As a function, we have:

f(x) = 1500x +3000

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 25
lozanna [386]

Answer:

The height of the building is of 244.95 feet.

Step-by-step explanation:

We use the Pythagorean Theorem to solve this question.

We have that:

The shadow of 50 feet is one side of the right triangle, while the height h is other side.

The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.

So

50^2 + h^2 = 250^2

h^2 = \sqrt{250^2 - 50^2}

h = 244.95

The height of the building is of 244.95 feet.

If you nee solving it will be:
c^6(-3c^5)^2
c^6(3c^5)^2
c^6·3^2(c^5)^2
c^6·9(c^5)^2
c^6·9c^10
9c^6c^10
9c^6+10
9c^16
So the answer is:
9c^16
(9c to the power of 16)
