Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the dT difference of T and the temperature of the region, Tror = k(T-TR). An object with core temperature of 1200°F is dt removed from a fire and placed in a region with a constant temperature of 80°F. After 1 hour, its core temperature is 830°F. What is the object's core temperature 4 hours after it is taken off the fire? (1 point) 370.4010°F 305.2214°F 225.2214°F 145.4010°F
