A fluid initially at 135 °C is placed outside on a day when the temperature is -30 °C, and the temperature of the fluid drops 40 °C in one minute. Let T(t) denote the Cemperature, in Celsius, at time t, in minutes. (a) Find the temperature T(t) of the fluid for t > 0. T(t) - (b) Find the temperature of the fluid 12 minutes after it is placed outside. Round your answer to two decimal places. T(12) = = °C
