The density of people (number of people per mile) during the evening rush hour for the 5 mile stretch along a certain sidewalk i

Kisachek [45]

Answer:

a. $\int\limits^5_0 {f(x)} \, dx$

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:

$\int\limits^5_0 {f(x)} \, dx$

Therefore, the answer is alternative a.
