Answer:

1. 117 sq. in.

2. 168 sq. in.

3. 99 sq. in.

Step-by-step explanation:

1. base x height = area

13 x 9 = 117 sq. in.

2. 1/2 x height x (base + base)

1/2 x 14 x (15 + 9)

1/2 x 14 x 24

Multiply 1/2 by 14 to get 7

7 x 24 = 168 sq in.

3. 1/2 d x d

1/2 x 18 x 11

Multiply 1/2 by 18 to get 9

9 x 11

Multiply 9 x 11 to get 99

9 x 11 = 99 sq. in.

Marymount Township secured the construction of a power plant, which opened in 1990. Once the power plant opened

Aleksandr [31]

Answer:

92087,14873

Step-by-step explanation:

Given that Marymount Township secured the construction of a power plant, which opened in 1990. Once the power plant opened in 1990, the population of Marymount increased by about 20% each year for the first ten years and then increased by 5% each year after that

Let P0 be the population in 1990

Then we have in 2000 the population is

$P(2000) = P_0(1.2)^{10}$

with this initial population for next growth we have in 2010 the population would be

$P(1.05)^{10}$ , where P = population is 2000

a) Given that $P(1.05)^{10) = 150000\\P = 150000(1.05)^{-10} =92.086.99\\=92087$

b) we use the exponential equation and solve for initial population in 2000.

c) we have

$P_0(1.2)^{10} =92087\\P_0 = 92087((1.2)^{-10})\\=14872.56\\=14873$

How can i get the output?

diamong [38]

In a function, you need to substitute your input value for x in order to get your output. For example, if you have the function f(x)=3x, and your input value is 3, you have to substitute in 3 for x. In this case, 3 x 3 is equal to 9, therefore, your output for 3 in this function is 9. Keep in mind that the output always changes between equations.
