Answer

A rectangular coordinate system with coordinates in miles is placed Ay with the origin at the center of a city. The figure to the right indicates that a university is located 1.3 miles west and 1.5 miles south of the center of the city. A seismograph on the campus shows that a small earthquake occurred. The quake's epicenter is estimated to be approximately 29 miles from the university. Write X the standard form of the equation for the set of points that could be the epicenter of the quake. (-1.3, -1.5) . . . What is the standard form of the equation of the circle? (Simplify your answer.)
