Me & explain! i will mark the correct answer brainliest!

The rate of change i believe is 150

Step-by-step explanation:

f(1)= 5(2)^1

f(1)= 5(2)

f(1)= 10

f(5)= 5(2)^5

f(5)= 5(32)

f(5)= 160

160-10=150

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
