9) Outside temperature over the course of a day can be modeled as a sinusoidal function. Suppose you know the high temperature of 105 degrees occurs at 5 PM and the average temperature for the day is 85 degrees. a) Write a sine or cosine function that models the temperature T as a function of the number of hours after midnight (12 AM). b) For how many hours of the day is the temperature cooler than 90 degrees?
