Question

a) Draw a diagram with all relevant constants and variables labelled.

b) Write a function expressing the quantity to be minimized/maximized as a function ofoneother variable. Show all the work required to derive this formula.

c) State the domain of the function covering all possible configurations for your problem.

d) Compute the derivative and determine all critical points of the function.

e) Analyze all critical points and endpoints to determine the minimum/maximum.

Tim and Miguel went to a fortune-teller at the state fair who tipped them off that their next calculus exam would have a problem involving ladders sliding down a wall. Cindy suggests they should replicate this in real life to gain an advantage on the rest of the class, so they all decide to bring a long ladder into their dorm. Tim further adds that they should use as long of a ladder as possible for an optimal experience. Cindy points out the problem that they must maneuver the ladder through a right-angle turn where the hallway constricts from 8 feet down to 5 feet wide. What is the longest ladder the trio can carry horizontally around the corner?
