After sitting out of a refrigerator for a while, a turkey at room temperature (72^\circ72∘F) is placed into an oven. The oven temperature is 315^\circ315∘F. Newton's Law of Heating explains that the temperature of the turkey will increase proportionally to the difference between the temperature of the turkey and the temperature of the oven, as given by the formula below: T=T_a+(T_0-T_a)e^{-kt}T=Ta+(T0−Ta)e−kt T_a=Ta= the temperature surrounding the objectT_0=T0= the initial temperature of the objectt=t= the time in hoursT=T= the temperature of the object after tt hoursk=k= decay constant The turkey reaches the temperature of 136^\circ136∘F after 2 hours. Using this information, find the value of kk, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the turkey, to the nearest degree, after 6 hours.
