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 t = 1 in January. In February, t = 2. Substituting t = 2 in the sinusoidal function gives:

y = `18.25*sin ((pi/6)*2 - 2.09) + 61.15 = 45.38`

The average temperature in February was 45.38 F
