Question

exponential growth

Answer 1

how many years from 1971 to 2015?

Answer 2

294,105(8.5)^44?

Answer 3

no

Answer 4

the 44 is right

Answer 5

to increase a number by \(8.5\%\) multiply it by \[100\%+8.5\%=108.5\%=1.085\]

Answer 6

to do it 44 times, compute \[294,105\times (1.085)^{44}\]

Answer 7

@satellite73 whats the final answer?

Answer 8

idk i didn't compute that number, i am sure you can do it

Answer 9

3802.750036629138

Answer 10

that what i get

Answer 11

i get something much much bigger

Answer 12

4096.75003663

Answer 14

also it says "round to the nearest whole number "

Answer 15

so 1.1?

Answer 16

@satellite73 im lost bro

Answer 17

the answer is written in scientific notation

Answer 18

bro i been waiting here lol =(

Answer 19

1.06515028525982306079399906161498607122884440956219587769... × 10^7

Answer 20

1.06515

Answer 21

move the decimal seven places

Answer 22

\[10,651,502\]

Answer 23

10.7?

Answer 24

@mathmale help bro

Answer 25

i wrote the answer above
the wolfram link gave it to you in scientific notation
the \(10^7\) at the end meant move the decimal seven places to the right

Answer 26

dont use wolf then use mathpapa

Answer 27

Please step back and review what you've done here. This problem involves exponential growth over a 44-year period. If you go further in math you will encounter exponential growth repeatedly, so it's worth learning the ropes.

You begin (in 1971) with 294105 female participants.
That number increases by 8.5% per year, over 44 years.
That's a LOT of growth.

What have you learned from working on this problem? Again, expect to see this material in the future.

Answer 28

10,651,502

Answer 29

Right. But that doesn't answer my question (above).

Answer 30

294,105*(1.085)^44

Answer 31

Yes, that's how you'd estimate the population after 44 years.

Answer 32

That's an "exponential growth equation."

Answer 33

3802.750036629138

Answer 35

What was the reason that you abandoned your first answer (10,651,502) and adopted the much smaller 3802.75 in its place? I need to understand y our reasoning.

Are we in agreement that the number of female sports participants is growing rapidly?

If so, which answer makes more sense (if we begin with 294105): 10651502 or 3803?

Answer 36

i dont know bro
