The temperature over a certain 24 hour period can be modeled with a sinusoidal function. At 3:00, the temperature
for the period reaches a low of 22◦F. At 15:00, the temperature for the period reaches a high of 40◦F.
- Find an equation that predicts the temperature based on the time in minutes. Chooset=0 to be midnight.
- Use the equation from #12 to predict the temperature at 4:00 PM.
- Use the equation from #12 to predict the temperature at 8:00 AM.
- Use the equation from #12 to predict the time(s) it will be 32◦F.
