Newton’s Law of Cooling expresses the relationship between the temperature of a cooling object y and the time t elapsed since cooling began, in minutes. This relationship is given by y = ae^-kt+c, where c is the temperature of the medium surrounding the cooling object, a is the difference between the initial temperature of the object and the surrounding temperature, and k is a constant related to the cooling object. The initial temperature of a liquid is 160 degrees F. When it is removed from the heat, the temperature in the room is 76 degrees F. For this object, k=0.23. Use Newton’s Law of Cooling to find the temperature of the liquid after 15 minutes.
