A pizza was baked at 450 degrees F and removed from the oven at 10:00 PM to cool in a 71 degree F room. After 5 minutes, the pizza was at 300 degrees F. Using a graphing utility to model the temperature over time, the time it would take for the pizza to cool to 135 degrees F was determined to be 10:13 PM. As time increases greatly, the graph shows the temperature will continue approaching the room temperature of 71 degrees F.
