Question 1118282: 1. One busy Chaperone pours herself some coffee into a paper cup before making her way to the amusement park. The coffee temperature is 350C when the cup is placed on the kitchen counter. The Chaperone is called to the phone for last minute arrangements, and her coffee is forgotten. When she finally returns to her coffee 35 minutes later, the temperature is now 210C.
a. What type of function best models the cooling of a hot liquid? Explain your choice.
b. What is the mathematical model for this situation? (i.e. - the equation)
c. If the optimal temperature for drinking a hot liquid is 280C, at what time would the chaperone have had to return in order to enjoy her cup of coffee?

You can put this solution on YOUR website! Physical nonsense: The coffee temperature is 350C when the cup is placed on the kitchen counter.
Much of what followed that was poor sense, too.
