Question

(04.04 MC) quadrilateral labeled warehouse with ellipse inscribed labeled whisper chamber with point at center and distance to two points on either side of the center labeled 5 meters and horizontal width of ellipse labeled 40 meters A designer wants to create a whisper chamber in the shape of an ellipse. He has a warehouse space with a longest length of 40 meters, which he decides will be the major axis of his elliptical chamber. He determines the best spots for his guests to stand to experience his whisper chamber will be 5 meters from the center of the warehouse space, which will act as the foci. How far out from the center, along the minor axis, should he build his whisper chamber? 19.4 m 38.7 m 39.7 m 79.4 m

Answer 1

19.4 m

Explanation:

Looking at the setup of the problem, the only possible answer is 19.4 m becuase it is the closest to twenty. The other answer explains it much more in depth, but i was able to get the question correct on my flvs test.

Answer 2

19.4 m

Explanation:

Without doing any math, you know the minor axis will be shorter than the major axis, so the side walls will be less than 20 m from center. There is only one answer choice in that range: 19.4 m.
