Question

Find the exponential function that satisfies the given conditions. (2 points)

Initial value = 30, increasing at a rate of 13% per year

f(t) = 30 ⋅ 1.13t
f(t) = 13 ⋅ 1.13t
f(t) = 30 ⋅ 0.13t
f(t) = 30 ⋅ 13t

I'm almost sure is A
@imqwerty ??

Answer 1

Find 13% as a decimal, and that will be your second part. Remember for decimals, you bring the decimal point from the very right over two spaces to the left.

Answer 2

So am i right ? @armyengineer225

Answer 3

If you mean that it is the first answer, no. 13% as a decimal is 0.13. Look for the answer that has 0.13.

Answer 4

that's not an increase of 13%. an increase in 13% = 113% or=1.13

Answer 5

so i was right? @♂

Answer 6

I think so

Answer 7

can you help me with one more?

Answer 8

give me a bit to check the graphs

Answer 9

Find the exponential function that satisfies the given conditions. (2 points)

Initial value = 70, decreasing at a rate of 0.5% per week

f(t) = 0.5⋅ 0.3t
f(t) = 70 ⋅ 1.005t
f(t) = 70 ⋅ 0.995t
f(t) = 70 ⋅ 1.5t

Answer 10

c

Answer 11

how did you get it?

Answer 12

i mean the percentage

Answer 13

0.5%=0.005
1-0.005=0.995

Answer 14

thanks :) can i ask you one more and that is it please?

Answer 15

yeah

Answer 16

The decay of 942 mg of an isotope is described by the function A(t)= 942e-0.012t, where t is time in years. Find the amount left after 71 years. Round your answer to the nearest mg. Show all of your work for full credit.
