Identify the initial amount a and the rate of growthr (as a percent) of the exponential function y = 25(1.2)t Evaluate the function when t=5. Round your answer to the nearest tenth.
a =
r=%
When I = 5, y =

y = 62.21

a = 25

r = 1.2 - 1 from (1 + r) part of the formula = .2 or 20%

Step-by-step explanation:

y = 62.21

y = final amount

y = a(1+r)^t

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
