When an object is removed from a furnace and placed in an environment with a constant temperature of 80F, its core temperature is 1234F. Eight hou must exist a time in the interval, (0,8), when the temperature is decreasing at a rate of 108F per hour.fift it let I(t) be the temperature of the object. Fill in the following values.T(0)=T(0)=SIIP 21 The average rate of change of temperature over the interval is given by the following.SIIP It By the mean value theorem, there exists a time t0,T'(t0)=Fh, such that T'(t0)=Fh
