ganeshie8 (ganeshie8):

use continuous growth formula

OpenStudy (anonymous):

which is ?

ganeshie8 (ganeshie8):

\(A = Pe^{rt} \)

OpenStudy (anonymous):

Can you help me ?

ganeshie8 (ganeshie8):

P : initial value r : rate of growth t : time A : final value

OpenStudy (anonymous):

Im bad at this

ganeshie8 (ganeshie8):

whats the starting population ?

ganeshie8 (ganeshie8):

read the problem and tell me if u can

OpenStudy (anonymous):

94,083

ganeshie8 (ganeshie8):

good :) so P = 94083

ganeshie8 (ganeshie8):

r = 5.5% = 0.055 t = 32

ganeshie8 (ganeshie8):

plug them in the formula

OpenStudy (anonymous):

OK

OpenStudy (anonymous):

@ganeshie8 what does e stand for in the formula?

myininaya (myininaya):

Looks like he did a good job of explaining. e is the number 2.7 approximately.

OpenStudy (anonymous):

Can you help me finish?

myininaya (myininaya):

Follow the order of operations.

OpenStudy (anonymous):

i am kind of in a rush

myininaya (myininaya):

Did you see the formula he gave? He even told you what each of the values in the formula would hold in this problem. Can you show me what you think the formula is with these given values?

myininaya (myininaya):

If you want, you can just draw it.
