[T] An anchor drags behind a boat according to the function y = 24 e − x / 2 − 24 , where y represents the depth beneath the boat and x is the horizontal distance of the anchor from the back of the boat. If the anchor is 23 ft below the boat, how much rope do you have to pull to reach the anchor? Round your answer to three decimal places.
