A pizza baked at 400°F is removed from the oven at 7:00 PM into a room that is a constant 73°F. After 5 minutes, the pizza is at 300°F. (a) At what time can you begin eating the pizza if you want its temperature to be 135°F? (b) Using a graphing utility, graph the relation between temperature and time. (c) Using INTERSECT, determine the time that needs to elapse before the pizza is 170°F. (d) TRACE the function for large values of time. What do you notice about y, the temperature?

Question
A pizza baked at 400°F is removed from the oven at 7:00 PM into a room that is a constant 73°F. After 5 minutes, the pizza is at 300°F.
(a) At what time can you begin eating the pizza if you want its temperature to be 135°F?
(b) Using a graphing utility, graph the relation between temperature and time.
(c) Using INTERSECT, determine the time that needs to elapse before the pizza is 170°F.
(d) TRACE the function for large values of time. What do you notice about y, the temperature?
(a) The temperature of the pizza is 135°F at about
PM.
(b) Choose the correct graph below. The graphing window is [0,135,10] by [0,400,80].
O A.
O B.
Oc.
Q
(c) Using INTERSECT, approximately minutes need to elapse before the pizza is 170°F.
(Type an integer or decimal rounded to the nearest tenth as needed.)
(d) Choose the correct answer below.
O A. The temperature of the pizza approaches 0°F.
O B. The temperature of the pizza approaches 400°F.
O C. The temperature of the pizza approaches 327 F.
O D. The temperature of the pizza approaches 73°F.
