A Ferris wheel at an amusement park is modeled by (x-80)2 + (y-80)2 = 5,625, where the measurements are in feet. A slingshot attraction is modeled by y=-3x² + 72x-280. Which attraction reaches a greater height, and what does it represent in terms of the context? The slingshot reaches a greater height at 280 feet, which is the vertex of the parabola. The Ferris wheel reaches a greater height at 155 feet, which is the highest point on the circle. The slingshot reaches a greater height at 152 feet, which is the vertex of the parabola. The Ferris wheel reaches a greater height at 150 feet, which is the highest point on the circle.
