Elvis Presley is an extremely popular singer. Although he passed away in 1977, many of his fans continue to pay tribute by dressing like Elvis and singing his songs.
The number of Elvis impersonators, N(t), for t number of years, can be modelled by the
function
N(t) = 170(1.31)^t
1. Write down the number of Elvis impersonators in 1977.
2. What is the percent rate of increase.
3. Calculate the number of Elvis impersonators when t=70; is this a reasonable prediction? Why or why not?

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

i believe that the slope of the line is -5

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

the answer is d

hope this
