A yam is put in a hot oven, maintained at a constant temperature 200°C. At time t = 30 minutes, the temperature T of the yam is 120° and is increasing at an (instantaneous) rate of 2°/min. Newton's law of cooling (or, in our case, warming) implies that the temperature at time t is given by Find a and b.
