Newton’s Law of Cooling (See the textbook for the formula) is used to determine time of death in homicide investigations. Assuming a normal body temperature of 98.6! F , and that time since death is measured in hours, the constant in Newton’s Law of Cooling is given to be k = 0.1947. Suppose the temperature of the room is 58! F : Find a function F (t ) , which models the body’s temperature t hours after death. Use EXACT V ALUES. If the temperature of the body at 8 PM was 62! F , what time did the person die? Please give the exact answer and a decimal approximation correct to 2 decimal places.

Question

Newton’s Law of Cooling (See the textbook for the formula) is used to determine time of death in homicide investigations. Assuming a normal body temperature of 98.6! F , and that time since death is measured in hours, the constant in Newton’s Law of Cooling is given to be k = 0.1947. Suppose the temperature of the room is

58! F :

  1. Find a function F (t ) , which models the body’s temperature t hours after death. Use EXACT

    V ALUES.

  2. If the temperature of the body at 8 PM was 62! F , what time did the person die? Please give the exact answer and a decimal approximation correct to 2 decimal places.
