1. A bacteria culture starts with 1000 bacteria, and after 2 hours the population is 2500 bacteria. Assuming that the culture grows at a rate proportional to its size, find the population after 6 hours. 2. 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. A roast turkey is taken from the oven when its temperature has reached 185 °F and is placed on a table in a room where the temperature is 75 °F. (a) If the temperature of the turkey is 150 °F after half an hour, what is the temperature after 45 minutes?
