The temperature T (in degrees Fahrenheit) of food placed in a refrigerator is modeled by 3t + 18t + 72 t + 3t + 10 where t is the time (in hours). T = 10 What is the initial temperature of the food in degrees Fahrenheit? F Find the rate of change of T with respect to t (in F/hr) at the following values. (Round your answers to two decimal places.) (a) t = 1 (b) (c) (d) t = 3 t = 5 t = 10 F/hr F/hr F/hr F/hr Interpret the meaning of these values. Each value is the initial temperature a particular food in the refrigerator. Each value is the temperature of the refrigerator at time t. Each value is the rate at which the temperature of the refrigerator is changing at time t. Each value is the rate at which the temperature of the food in the refrigerator is changing at time t. O Each value is the temperature of the food in the refrigerator at time t.
