police arrive at a murder scene at 1:30 am and immediately record the body's temperature which was 93 degrees Fahrenheit. at 2:00 am, after thoroughly inspecting and fingerprinting the area, they again took the temperature of the body which had dropped to 83 degrees F. the temperature of the crime scene has remained at a constant 70 degrees F. Determine when the person was murdered. (assume that the victim was healthy at the time of death. that is, assume that the temperature of the body at the time of death was 98.6 degrees F)

Murder Investigation: When a glass of wine with a certain temperature is placed into a room, its temperature will converge to the room’s temperature according to the formula: F(t)=Fs+(F0-Fs) -.3t. Where F(t) is the temperature of the object after being in the room for t hours, F0 is the initial temperature of the object, and Fs is the temperature of the room that the object is in. Use this formula to investigate the scenario below and answer the following questions....
