A) Determine an equation for the population with respect to the number of years after
2014
, assuming that the population increases at a constant rate.
Solution
The function will be of the form
p
=
a
r
n
, where
a
is the initial population,
r
is the rate of increase,
n
is the time in years and
p
is the population.
p
=
584
,
513
(
1.0002
)
n
b) Using this model, estimate the population of Wyoming in
17
years.
solution
Here,
n
=
17
.
p
=
584
,
513
(
1.002
)
17
p
=
604
,
708
c) Using this model, determine in how many years it will take for the population to exceed
600
,
000
.
1700000000You see there is no decimal... so we have to put one. Whenever there is no decimal, its just add the end ;)
Now our number has to be greater then 1 but less than 0.
So as you can see 17 is greater then 10. So what about 1.7? Yes thats greater then one but less than 0!
So lets see how many spaces it takes to move the decimal there.
I got 9.
So then we do this:
1.7*10^9
Got it?
