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, if this difference is not too large. A piece of meat at room temperature (18°C) is placed in a refrigerator where the temperature is 2°C. After half an hour the meat has cooled to 6°C. What is the temperature of the meat after another half hour?
(e) The variablesy and t satisfy the differential equation Ti1 = (y + 2)sin2t. Also, when t = 0,y = 0. Find the exact value ofy when t = 714. You must use calculus and give the results of any integration needed to solve this problem (e) The diagram shows how the curvey = ex […]
