Question
3. A swarm of insects is centered around a light source. At a distance of p meters away from the light source,
the population density is 8(p) = 100 – 25p insects per cubic meter, where 0 <p< 4.
(a) Where is the population density the greater, near the light source or farther away from it? Explain.
(b) Set up an iterated integral that gives the total number of insects in the swarm. Then, evaluate the
integral by hand, showing your work.
