A man on a dock is pulling in a boat by means of a rope attached to the bow of the boat at a point that is 1 ft above water level. The rope goes from the bow of the boat to a pulley located at the edge of the dock 8 ft above water level. If he pulls in the rope at a rate of 3 ft/sec, how fast (in feet per second) is the boat approaching the dock when the point of attachment is 13 ft from the dock? ft/sec DETAILC DDEVIONIC ANSWERS MY NOTE [-/5 Points] DETAILS MY NOTES A point P(x, y) moves along the graph of the equation y = x + x+ 2.
