Someone starts pumping oil into the tank at a constant rate of 10 liters per second. Simultaneously, oil starts flowing out through the outlet in the base at the rate ² (in liters per second) at time t. a. Find the differential equation that would describe the volume of the oil in the tank at time t (in seconds). b. Find the volume of the oil in the tank at timet (in seconds). c. Will the tank ever be empty? Explain. 9 10
