The function
roughly models the life expectancy E (in seconds) of an animal in captivity that has a mass of m kilograms. The function
approximates the heart rate R (in beats per second) of an animal with a mass m (in kilograms). Approximately how many times will a greater kudu’s heartbeat over its expected lifetime in captivity?

Since the units for E(m) are seconds and the units for R(m) are heartbeats per second, multiply the functions to determine the total number of heartbeats. For the greater kudu, replace m with 200.
