![The normal monthly precipitation at the Seattle-Tacoma airport can be approximated by the model shown below, where R is measured in inches and t is the time in months, with t = 0 corresponding to January 1. (Round your answers to two decimal places.) R = 2.876 + 2.202 sin(0.576t + 0.847) (a) Determine the extrema of the function over a one-year period. relative minimum (t, R) = ( ), relative maximum (t, R) = ( ), (b) Use integration to approximate the normal annual precipitation. (Hint: Integrate over the interval [0, 12].) in (c) Approximate the average monthly precipitation during the months of June, July, and August. in](https://www.doubtrix.com/uploads/editor/2944063509AgmljYiKFe.png)
