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+2.8 cos 2π 365 In this equation, L (t) is the number of sunlight hours in a day, and t is the number of days after June 21st. (So t=0 means June 21st, t=1 means June 22nd, t=2 means June 23rd, etc.) Suppose we start at t=0, which is June 21st. During the first 365 days, when will there be 10 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.)

Transcribed Image Text: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+2.8 cos
In this equation, L (t) is the number of sunlight hours in a day, and it is the number of days after June 21st. (So t=0 means June 21st, t=1
means June 22nd, t=2 means June 23rd, etc.) Suppose we start at t=0, which is June 21st.
