The yield V (in pounds per acre) for an orchard at age t (in years) is modeled by the function below. V = 7985.2e-0.0454/t
At what rate is the yield changing at each of the following times? (Round your answers to two decimal places.)
(a)
t = 5 years
X pounds per acre per year
(b)
t = 10 years
x pounds per acre per year
