A marketplace in Australia is in the shape of an ellipse. We can assume the center of the marketplace is at the point (0, 0), the location of one ofthe foci is at the point (727 0), and the length of the minor axis is 96. Determine the location of each of the vertices of the marketplace. Assume that the major length is horizontal and round your answer to the nearest thousand if needed. Font Family 7. The height of a rider on the Star of Lake Tai Ferris wheel in China can be determined using the following equation: h-(t) = 67.5 COS[:1'Ell) + 69.5 Assume that one full rotation takes 30 minutes. For how many minutes is the cabin 100 meters or more above ground? Keep in mind that the cabin begins and ends two meters off of the ground, not quite at ground level. U Font Family
