2. write a function that models the relationships among x, y, and r. (hint: use the pythagorean theorem.)
then solve the equation for rin terms of x and y.
(3 points: 1 point for the correct pythagorean setup, 1 point for work, 1 point for the solution)

You remove a cheesecake from the oven with an ideal internal temperature of 165 f and place it into a 35 f refrigerator. after 10 minutes, the cheesecake has cooled to 15o f if you must wait until the cheesecake has cooled to 70 before you eat it, how long will you have to wait?
