​Newton's Law of Cooling says that the rate at which a body cools is proportional to the difference C in temperature between the body and the environment around it. The temperature​ f(t) of the body at time t in hours after being introduced into an environment having constant temperature T0 is f(t)=T0+C e −kt​, where C and k are constants.   A cup of coffee with temperature 130°F is placed in a freezer with temperature 0°F. After 5 minutes, the temperature of the coffee is 87°F. Use​ Newton's Law of Cooling to find the​ coffee's temperature after 10 minutes.
