or 5.14/14 points | Previous AnswersA ladder 25 feet long is leaning against the wall of a building. Initially, the foot of the ladder is 7 feet from the wall. The foot ofthe ladder begins to slide at a rate of 2 ft/sec, causing the top of the ladder to slide down the wall. The location of the foot of theladder at time tseconds is given by the parametric equations (7+2t,0)(a) The location of the top of the ladder will be given by parametric equations (0,y(t)). The formula for y(t)$$√252−(7+2t)2. (Put your cursor in the box, click and a palette will come up to help you enter your symbolicanswer.). =
