T(t) = 51 + 140e−0.05t
where t is measured in minutes and T 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
(a) Set t = 0, then T = 51 + 140 = 191 F
(b) Set t = 10, then T = 51 + 140e^(-0.05*10) = 135.9 F
