The elliptical ceiling of a building is 86 ft long and 17 ft tall. 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? (-43,0) (a) The standard form of the equation is = 1. (0,17) (43,0)
