I(t) models the daily solar irradiance, measured in kWh/m2-day on a farm, t days after the summer solstice. Here, t is entered in radians. I(t) = 1.5cos(2π/365*t)+4.3 What is the second time after the summer solstice that the solar irradiance is 5.2kWh/m2-day Round your final answer to the nearest whole day.
