. In a simple model of territory, a single animal defends a circular territory of radius x (miles). The following assumptions are made: • the energy L spent per day in looking for food and defending the territory is directly proportional to the area of the region • the energy G gained per day is directly proportional to the radius x Suppose that L = 3000 calories and G = 3500 calories when x 1. Find the territorial size that will result in maximum benefit to the animal, that is, maximize the net energy G- L.

Question
Transcribed Image Text:5. In a simple model of territory, a single animal defends a circular territory of
radius x (miles). The following assumptions are made:
• the energy L spent per day in looking for food and defending the territory
is directly proportional to the area of the region
• the energy G gained per day is directly proportional to the radius x
Suppose that L = 3000 calories and G = 3500 calories when x = 1. Find
the territorial size that will result in maximum benefit to the animal, that is,
maximize the net energy G- L.
