question 5

Multiple Choice

Scientists sometimes use the formula to simulate temperature variations during the day, with time t in hours, temperature f ( t ) in , and t=0 corresponding to midnight. Assume that f ( t ) is decreasing at midnight. Determine values of a, b, c, and d that fit the information: the high temperature of 29 occurs at 2 P.M., and the average temperature of 21 occurs 6 hours later.
