1-Outside temperature over the course of a day can be modeled as a sinusoidal function. Suppose the temperature varies between 61F and 88F during the day and average daily temperature first occurs at 12AM. How many hours after midnight does the temperature first reach 68F? Round your answer to 3 decimal places.

2-A rabbit population oscillates 15 above and below average during the year, reaching the lowest value in January. The average population starts at 750 rabbits and increases by 130 each year. Find a function that models the population P, in terms of months since January, t p(t)=
