This phenomenon is known as the thermic effect of food. Suppose that for one particular person, the thermic effect of food is given by the following equation, where F(t) is the thermic effect of food (in kJ/hr) and t is the number of hours that have elapsed since eating a meal. Complete parts (a) and (b) below. F(t) = - 10.29 + 175.6te 1.3 , fort > 0 a. Find F'(t). F' (t) = (Use integers or decimals for any numbers in the expression.
