Shown below is the graph of cup 1. The initial temperature of the coffee is 180° F and k is 0.2337 (for time in minutes). Sketch and label a graph of cup 2 on the same coordinate plane. Cup 2 is poured 10 minutes after cup 1 (the pot of coffee is maintained at 180°F over the 10 minutes).
Shown below is the graph of cup 1. The initial temperature of the coffee is 180° F and k is 0.2337 (for time in minutes). Sketch and label a graph of cup 3 on the same coordinate plane. Cup 3 is immediately taken outside where the temperature is 90°F.
