Homework Help: calculus

Posted by Gabe on Friday, February 12, 2010 at 4:19pm.

A boat is pulled into a dock by a rope attached to the bow of the boat and passing through a pulley on the dock that is 1 m higher than the bow of the boat. If the rope is pulled in at a rate of 1 m/s, how fast is the boat approaching the dock when it is 9 m from the dock?

I am getting "-[(82)^(1/2)]/9", but the computer isn't liking it.

I also get -√82/9 m/s

The negative signs shows me that the distance between the dock and the boat is decreasing.
Try entering the positive result of that.
or the decimal equivalent of 1.006
