Acity is built around a circular lake that has a radius of 1 mile. the population density of the city is f (r) people per square mile, where r is the distance from thecenter of the lake, in miles. which of the following expressions gives the number of people who live within 1 mile of the lake?

intergral 2pi rf(r) dr from 1 to 2 is the expression that gives the number of people who live within 1 mile of the lake. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
