b.
Answer to Problem 63E
Monthly increase is around 0.45%.
Explanation of Solution
Given information :
Initial population is 25000.
Population increases by 5.5% annually for the next decade.
Let us take x be the monthly percent increase in population.
We get,
Now we shall compare the equation we got in part a.
Hence the monthly increase is around 0.45%.
c.
To graph the function.
c.
