newton's law of cooling is T=Ae^-kt+C where T is the temperature of the object at time t, and C is the constant temperature of the surrounded medium. The temperature of a cake is 390 degrees when it is removed from the oven. The temperature in the room is 68 degrees. In 11 minutes, the cake cools to 310 degrees. How long will it take the cake to cool to 130? While solving this problem, round the value of k to seven decimal places. Round your answer to two decimal places.
