Answer:
a.
Step-by-step explanation:
Since f(x) is the function for the populational density at a certain sidewalk for a 5 mile stretch, a definite integral of that function will yield the total number of people within the integration intervals. If we are interested in the number of people in the whole 5 mile stretch, we must integrate f(x) from x = 0 miles to x = 5 miles:
Therefore, the answer is alternative a.
First find a common denominator and combine the fractions in the numerator:
Now simplify and cancel out all the terms that you can:
Since the remaining expression is continuous as a function of
, you can directly substitute to end up with
