- In your own words, define an ellipse and write the equation of an ellipse centered at the origin in standard form. Draw a sketch of the ellipse labeling the center, vertices and major and minor axes.arrow_forwardStatuary Hall is an elliptical room in the United States Capitol in Washington, D.C. The room is also called the Whispering Gallery because a person standing at one focus of the room can hear even a whisper spoken by a person standing at the other focus. This occurs because any sound emitted from one focus of an ellipse reflects off the side of the ellipse to the other focus. Statuary Hall is 46 feet wide and 97 feet long. (a) Find an equation that models the shape of the room. (b) How far apart are the two foci? (c) What is the area of the floor of the room? (The area of an ellipse is A=ab.)arrow_forwardDefine an ellipse in terms of its foci.arrow_forward
- A planet moves in an elliptical orbit around its sun. The closest the planet gets to the sun is approximately 20 Au and the furthest is approximately 30 AU. The sun is one of the foci of the elliptical orbit. Letting the ellipse center at the origin and labeling the axes in AU, the orbit will look like the figure below, use the graph to write an equation for the elliptical orbit of the planet.arrow_forwardWhat special case of the ellipse do we have when the major and minor axis are of the same length?arrow_forwardFind an equation for the ellipse with center (2, 0), foci (2,3) and major axis of length 8.arrow_forward
- A person in a whispering gallery standing at one focus of the ellipse can whisper and be heard by a person standing at the other focus because all the sound waves that reach the ceiling are reflected to the other person. If a whispering gallery has a length of 120 feet, and the foci are located 30 feet from the center, find the height of the ceiling at the center.arrow_forwardPlywood Ellipse A carpenter wishes to construct an elliptical table top from a 4 ft by 8 ft sheet of plywood. He will trace out the ellipse using the “thumbtack and string” method illustrated in Figures 2 and 3. What length of string should he use, and how far apart should the tacks be located, if the ellipse is to be the largest possible that can be cut out of the plywood sheet?arrow_forwardExplain in your own words, the difference between a vertex and a focus of the ellipse.arrow_forward
