For a fixed location the number of sunlight hours in a day fluctuates throughout the year Suppose that the number of daily sunlight hours in a particular location can be modeled by the following L t 12 2 9 cos 2 365 In this equation L t is the number of sunlight hours in a day and I is the number of days after June 21st So 1 0 means June 21st 1 1 means June 22nd 1 2 means June 23rd etc Suppose we start at 1 0 which is June 21s During the first 365 days when will there be 13 hours of sunlight Do not round any intermediate computations and round your answer s to the nearest day If there is more than one answer enter additional answers with the or button t days after June 21 st of D
