1.6 Piecewise crickets (6 points) Walking around at night, there are times when you can hear crickets chirp. It is surprising that all crickets chirp at essentially the same rate if they are at the same temperature. Therefore, we can view the chirp rate as a function of temperature. It is more surprising that the chirp rate, C, in chirps per minute, increases steadily with the temperature, T, in degrees Fahrenheit. This is known as Dolbear's law 300 250 200 150 100 50 B 20 40 60 80 120 140 160 -50 1. Suppose you walked outside and measured 90 chirps per minute. What temperature do you expect it to be? 2. Based on the graph of the function C = f(T), if you walked outside on a chilly 70 F day, about how many chirps per minute would you expect to hear? 9
