Let me put the times, second insert times just to make sure it understands that. Okay, so that's my function, and then let me throw a comma here, make it clear that I'm integrating with respect to x. I could have put a t here and integrated with respect to t, we'd get the same value. Comma, my lower bound is zero, and my upper bound is eight, and close the parenthesis and then let the calculator munch on it a little bit. And we get 76.570, so this is approximately 76.570. Now let's tackle the next part. Is the amount of water in the pipe increasing or decreasing at time t is equal to three hours? Give a reason for your answer.
