## Math Problem Statement

an oil tank contains some oil. the oil is leaking from the tank. it is found that the volume of oil V (in cm3) in the tank can be estimated by v=32(3+e^(1/5t))^(-1). and t(t>=0) is the number of hours elasped since the leaking begins. find the value of V when dV/dT attains its least value
