Answer:
5% annual population growth rate
Step-by-step explanation:
Let the percent the population grows by be  . The total population,
. The total population,  , after
, after  years can be modeled by the function:
 years can be modeled by the function:

Why?
Let's take a look at a simple example. If we said a number  grew by 10%, we could represent the number after it grew by multiplying
 grew by 10%, we could represent the number after it grew by multiplying  by
 by  . This is because growing by 10% is equivalent to taking
. This is because growing by 10% is equivalent to taking  of that number and we convert a percentage to a decimal by dividing by 100.
 of that number and we convert a percentage to a decimal by dividing by 100. 
Therefore, if the population grew  , we would divide it by 100 to convert it to a decimal, then add 1 (100%) and raise to the power of
, we would divide it by 100 to convert it to a decimal, then add 1 (100%) and raise to the power of  (number of years) to multiply by the initial population of 40,000 to get the total population after
 (number of years) to multiply by the initial population of 40,000 to get the total population after  years.
 years.
Since the population of the town after two years is 44,100, substitute  and
 and  into
 into  :
:

Therefore, the city has an annual population growth rate of 5%.

Both 52 and 5x-8 are equal to each other due to being parral.
SO 5x-8=52
Add both sides.
8+8 52+8= 60
5x 60
Now divide both sides by 5 and you get 12=x Hope this helps!
