A rectangular coordinate system with coordinates in miles is placed with the origin at the center of a city. The figure to the right indicates that a university is located 3.8 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 37 miles from the university. Write the standard form of the equation for the set of points that could be the epicenter of the quake. Ay 37 miles -3.8,-1.5) What is the standard form of the equation of the circle? (Simplify your answer.)
