Answer:

We just plug in 2,430,000 for r and when we do so we get:

f(r) = √7.2 * 2,430,000 = 1080 * √15 = 4,200.

Find the area *15 points*
vova2212 [387]

Answer:

The answer to your question is 780 ft²

Step-by-step explanation:

- Divide the figure into two sections an upper part and a lower part.

- Area of the upper part = base x height

                                        = 40' x 18'

                                        = 720

-Area of the lower part

 base = 40' - 30' = 10'

 height = 24' - 18' = 6'

  Area = 10 x 6 = 60

- Total area = Area Upper part + Area lower part

                   = 720 + 60

                   = 780 ft²

Daniel [21]

<u>Given</u>:

The cost for the children’s party at the rollerskating rink is a function of n, the number of people in the party. The cost function, C is given by

C(n)=\left\{\begin{array}{ll}150, & 0

We need to determine the cost to have a party with 9 people and the cost to have a party with 20 people.

<u>Cost of having the party:</u>

From the given function, the cost of having the party for 9 people lies in the interval 0

Hence, the cost of having the party for 9 people is 150.

Also, from the function, the cost of having the party for 20 people lies in the interval 12

Hence, the cost of having the party for 20 people is 260.
