Please put the test problem number at the beginning of your work so your instructor can match the work to the correct problem. A "whispering room" is one with an elliptically-arched ceiling. If someone stands at one focus of the ellipse and whispers something to his friend, the dispersed sound waves are reflected by the ceiling and concentrated at the other focus, allowing people across the room to clearly hear what he said. Suppose such gallery has a ceiling reaching 6 above the five-foot-high vertical walls at its tallest point (so the cross-section is half an ellipse topping two vertical lines at either end), and suppose the room is 30 feet wide. How far from the wall is each "whispering point"? "whispering point" = ' feet from the k wall. (Please round to two decimal places at least)
