| and on the oil problem (last part), i got..
Volume = 60,000 + [integral from 0 to 25 of (2000 - R(t)) dt]
didn't the question say that when the machine was hooked up and the oil began to removed, the volume was already 60,000, and then it asked how much was the total volume when the oil reached its max (which would make my integral right)? |
