For #3 I need an exact answer- how do I do this? It’s test practice and ungraded

solve for P = 82000 (and round up, if applicable)

#

slender meteor solve for P = 82000 (and round up, if applicable)

I Need the exact answer

#

How do I find that using logs?

slender meteor Mar 31, 2023, 6:05 PM

#

so P0 (1 + r)^n = 82000

#

what happens if you log both sides?

#

(you want to solve for n)

#

So what now?

slender meteor (you want to solve for n)

Shoot forgot to reply

#

slender meteor what happens if you log both sides?

what did you get?

#

It didn’t work

#

slender meteor what did you get?

Tbh idek where to begin

#

Can you walk me through?

slender meteor Mar 31, 2023, 6:26 PM

#

we want to find

P = 82000

#

we have

P = P0 (1 + r)^n

#

hence

P0 (1 + r)^n = 82000

#

now, take ln of both sides

#

So P0 being 28150 is correct, right?

slender meteor Mar 31, 2023, 6:29 PM

#

yes

full dawn Mar 31, 2023, 6:30 PM

#

And how do I find r?

#

I guessed nd checked LMAOO

slender meteor Mar 31, 2023, 6:32 PM

#

the population was 40754 in 2014, so

28150 * (1 + r)^9 = 40754

OHH so

#

Wait

#

No
