Orbit of a Satellite A satellite is in orbit around the moon. A coordinate plane containing the orbit is set up with the center of the moon at the origin, as shown in the graph, with distances measured in megameters (Mm). The equation of the satellite’s orbit is
- (a) From the graph, determine the closest and the farthest that the satellite gets to the center of the moon.
- (b) There are two points in the orbit with y-coordinates 2. Find the x-coordinates of these points, and determine their distances to the center of the moon.

- Astronomy Some comets have a hyperbolic orbit, with the sun as one focus. When the comet shown in the illustration is far away from Earth, it appears to be approaching Earth along the line y=2x . Find the equation in standard form of its orbit if the comet comes within 100 million miles of Earth.arrow_forwardJared flies a drone in a circular path around an object that is 250 feet north and 240 feet west of his position. The drone's path takes it over a point that is 150 feet south and 190 feet east of him. Find an equation for the drone's path. (Assume Jared is located at the origin, with the horizontal axis running east-west and the vertical axis running north-south) The drone's path follows the equation When the drone passes due south of Jared's position, it will be feet south of him (round your answer to three decimal places).arrow_forwardThe elliptical ceiling of a building is78ft long and22fttall. Use the rectangular coordinate system in the figure shown to write the standard form of the equation for the elliptical ceiling. A man discovered that he could hear conversations of colleagues in the entire room if he stood at the focus, (c,0), where c2=a2−b2. How far along the major axis did the man stand to hear the conversations? (a) The standard form of the equation is=1. (b) The man stood feet from the center of the ellipse. (Round to the nearest whole number as needed.)arrow_forward
- The wheel in the adjacent figure has a radius of 65 feet. The clearance between the wheel and the ground is 15 feet. The rectangular coordinate system shown has its origin on the ground directly below the center of the wheel. Use the coordinate system to write the equation of the circular wheel.arrow_forwardplot each point. Then plot the point that is symmetric to it with respect to (a) the x-axis; (b) the y-axis; (c) the origin.

- The Ferris wheel in the figure has a radius of 68 feet. The clearance between the wheel and the ground is 14 feet. The rectangular coordinate system shown has its origin on the ground directly below the center of the wheel. Use the coordinate system to write the equation of the circular wheel.arrow_forwardWrite the equation of the height of a rider on each of the following Ferris wheels t seconds after the rider passes the farthest right position. a. The radius of the wheel is 30 feet, the center of the wheel is 45 feet above the ground, and the angular speed of the wheel is 15 degrees per second counterclockwise. Equation: b.
