45. Researchers find a creature from an alien planet. Its body temperature is varying sinusoidally with time. 35 minutes after they start timing, it reaches a high of 120 ̊ F. 20 minutes after that it reaches its next low, 104 ̊ F.

A.) Write a sinusoidal function analytically that expresses temperature in terms of time (in minutes) since they started timing.

The function is: _______________________________________________________________________

B.) Find the first three times after they started timing at which the temperature was 114 ̊ F. _________________________________________________________________ 46. The following is the data for 24 hour average temperature for Florence, Italy for the average temperature measurements for the 12 months of several of the last few years. A.) Write a sinusoidal function analytically for the data B.) Write a regression equation
