Berri and Alana are standing on opposite sides of a planetarium, a room with a dome ceiling in the shape of a semi-ellipse. The planetarium is 10 feet high and 75 feet wide. If each stands at the focus on their side, they'll be able to hear each other in a whisper. How many feet apart should they stand?

Use a calculator to verify that Ο(x) = 62, Ο(x2) = 1034, Ο(y) = 644, Ο(y2) = 93,438, and Ο(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
