Question

A population of squirrels numbered 50 on 30 June 1980. On 30 June 1990, the
population of squirrels numbered 600 000 000. The population can be modelled using the
exponential population model.

Answer 1

could you do the last one elizated?

Answer 2

Determine the yearly growth rate of this population of squirrels.

Estimate the squirrel population on 30 June 1985

Answer 3

Sorry Paul, I'm not good with exponential functions. I like my lines straight.

Answer 4

i should just put a picture of some girl on my profile and change my name to get some help around here... gah

Answer 5

N = P * r^t
N = population,
r = rate of growth
t = time
P = initial population

Answer 6

so all i need to do is know how to use logs...

Answer 7

yup, that would be helpful

Answer 8

eliza do you know?

Answer 9

im having a bit of trouble getting r from

\[10 \log (r) = \log 12*10^7\]

Answer 10

wait up

Answer 11

no. i don't know what log is, don't expect me to know how to use it!

Answer 12

i think i have it

Answer 13

log r = .70791...

Answer 14

ahhh

im so close aren't i

Answer 15

brain ... growing

Answer 16

yeah. try using google

Answer 17

must figure out by self

Answer 18

or wolfram alpha, both have built in calculators

Answer 19

i feel like theres some simple step im missing that i should know... can you tell me it?
