Suppose that the number of hours of daylight on a given day in Seattle is modeled by the function F(t) = 12.25 -3.75 cos( in months and t= 0 corresponding to the winter solstice. (a) What is the average number of daylight hours per day over the course of a year? (b) At which times t, and t₂, where 0 ≤t₁ < t < 12 do the number of daylight hours equal the average number? 41- and 12 (c) Write and integral that expresses the total number of daylight hours in Seattle between f, and t₂ 2 with t given
