Newton's Law of Cooling Says That the Rate of Change

Multiple Choice

Newton's Law of Cooling says that the rate of change (with respect to time t in minutes) of the temperature T of an object is proportional to the difference between the temperature of the object and the temperature A of the object's surroundings. Initially, the object has a temperature of If the object is placed in a room where the temperature is fixed at and the object begins to cool at a rate of 2.3 degrees per minute, determine the constant of proportionality. Round your answer to four decimal places.

A) -0.3333
B) -2.3000
C) -0.1667
D) -4.6000
E) -6.0000
