Applications of Exponential & Log Function Derivatives

6. A casting is taken from one oven at 1500F and placed into another at 0F, but rising at a rate of 100o/hr. The temperature is then:

                T = 100t + 1500e-0.2t

Find the minimum temperature and when it occurs.

    You know the steps: Take the derivative with respect to time, zero it equal to zero, and solve.
