Place the regions in order according to their population densities from least to greatest.

Region C ⇒ Region A ⇒ Region B

Step-by-step explanation:

Density = Number of people / Area of region

The regions are in circles based on the fact we were given the radius and area of circle = π * radius²

Region A Density = 14,200,000 / (3.142 * 13²)

= 26,742 people per square mile

Region B Density = 19,700,000 / (3.142 * 15²)

= 27,866 people per square mile

Region C Density = 23,550,000 / (3.142 * 18²)

= 23,133 people per square mile

Order from least to greatest is:

Region C ⇒ Region A ⇒ Region B

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
