This exercise uses Newton's Law of Cooling. A hot bowl of soup is served at a dinner party. It starts to cool according to Newton's Law of Cooling so that its temperature at time t is given by T(t) = 61+138e-0.05t where t is measured in minutes and 7 is measured in °F. (a) What is the initial temperature of the soup? °F (b) What is the temperature after 10 min? (Round your answer to one decimal place.) °F (c) After how long will the temperature be 100°F? (Round your answer to the nearest whole number.) min
