What is letter D ??
(2 points) Suppose you have just poured a cup of freshly brewed coffee with temperature 90°C in a room where the temperature is 25 C. Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Therefore, the temperature of the coffee, T(t), satisfies the differential equation dT dt = k(T-Troon) where Troom 25 is the room temperature, and k is some constant. Suppose it is known that the coffee cools at a rate of 2° C per minute when its temperature is 65°C. A. What is the limiting value of the temperature of the coffee? lim T(t) 25 B. What is the limiting value of the rate of cooling? dT 11m _ = C. Find the constant k in the differential equation. k = |-0.05 D. Find the temperature of the coffee at time t T(t) = | |
