Entomologists have discovered that a linear relationship exists between the number of chirps of crickets of a certain species and the air temperature. When the temperature is 90° F, the crickets chirp at the rate of 200 times/minute, and when the temperature is 110° F, they chirp at the rate of 300 times/minute. Find an equation giving the relationship between the air temperature T and the number of chirps/minute N of the crickets.

A town is experiencing a growth pattern of 3% per year in its population P; that is
dP / dt = 0.03P where P is the population of the town and t is the time, in years, from 2005. (a) Given that the town’s population in 2005 was 14,000, find the solution of the equation assuming 0 P =14,000 and k = 0.03 . (b) What will the population be in 2015? (c) What is the doubling time of the population?
