5. A warm object in a cooler room will decrease in temperature exponentially, approaching the room temperature according to the formula Tn=a(1-r)" +T, where Tn is the temperature after n minutes, r is the rate at which temperature is changing, a is a constant, and T, is the temperature of the room. Forensic investigators can use this to predict the time of death of a homicide victim. Suppose that when a body was discovered (n = 0) it was 85 degrees. After 20 minutes, the temperature was measured again to be 80 degrees. The body was in a 70 degree room. a.
