Question 1144872: Glo-Tek Industries has designed a new halogen street light fixture for the city of Seattle. According to the product literature, when placed on a 50 foot light pole, the resulting useful illuminated area is a circular disc 120 feet in diameter. Assume the light pole is located 20 feet east and 40 feet north of the intersection of Parkside Ave. Write the equation of the illumanted area and graph the function. Answer by ikleyn(52778) (Show Source):
It is the standard equation of the circle of the radius 120 ft centered at the point (20,40) in a coordinate plane
+ = ,
where x is the East coordinate in feet and y is North coordinate, in feet.
The origin of the coordinate system is the intersection mentioned in the post.
