The average temperature, in °F, for Atlanta, GA is modeled by the sinusoidal function y = 18.25 sin(pi/6 t - 2.09) + 61.15 where t is the time in months and January is t=1.
What is the average Temperature for the month of February?
Using the same equation, what is the average temperature in Atlanta, GA, for the month of June?
plug in t=2 to get
18.25 sin(pi/6 * 2 - 2.09) + 61.15 = 45.38
for June, plug in t=6.
