HELP! WILL MEDAL!

Lori has determined a function f(x) that shows the exponential growth of the number of jeans Tim owns each year. Explain how the f−1(x) can be found and what f−1(250) means.

Answer 1

1/ Have to assume that Harrison has also picked an acct with a high interest rate. If so his plan would make the most money


If bases were equal:

50x = 17x
50x-17x = 0
35x = 0
x= 0

Answer 2

I don't think this has anything to do with my question..

Answer 3

no...it doesn't. I accidentally copied the wrong thing.

Answer 4

sorry

Answer 5

let me try it again

Answer 6

Lol! Its ok.. just a lil confusing :)

Answer 7

\[f ^{negative1}\] means the year in which Tim owns 250 pairs of jeans

Answer 8

how would I Explain how the f−1(x) can be found?

Answer 9

it is found by taking the inverse of the exponential function aka the logarithm

Answer 10

Ok, thanks. How about this one?

Kylee is managing a small theme park and has been analyzing the attendance data. Kylee has found that the number of visitors increases exponentially as the temperature increases. Kylee has also found a linear equation that models the number of people who leave the park early depending on the temperature. Describe how Kylee can combine these two functions into a new function and explain what that function would predict.

Answer 11

not sure

Answer 12

Answer 13

any others?

Answer 14

Yes!

Answer 15

Patrick and Brooklyn are making decisions on their bank accounts. Patrick wants to put money in an account that has a higher interest rate but only gains interest for a short period of time. Brooklyn wants to put the money in an account with a lower interest rate, but it gains interest for a longer period of time. Explain which method will result in more money.

Answer 16

It is simple

Answer 17

the interest rate that Patrick put his money into will result in less money, because it only earns interest over a shorter period of time. Right?

Answer 18

Im not sure. Im confused about this.

Answer 19

Brooklyn's account will earn more money because it has a longer period of time on the interest time.

Answer 20

think about this:

$5 for two days=$10

Answer 21

Is there an equation that I would use to explain this? Pe^rt?

Answer 22

$2 dollars for 10 days = $20

Answer 23

yes it is that, but there is no numbers to do that with

Answer 24

thats all I can do

Answer 25

I need to go
