The equation of a circle is (x+4)2+(y−5)2=121.1.) What is the center and radius of the circle? center: (−4, 5); radius: 11 center: (−4, 5); radius: 121 center: (−4, −5); radius: 121 center: (4, −5); radius: 112.) One of the lamp posts at a bank has a motion detector on it, and the equation (x+15)2+(y−12)2=25 describes the boundary within which motion can be sensed.What is the greatest distance, in feet, a person could be from the lamp and be detected? 5 ft 10 ft 50 ft 125 ft3.) Jenni plots her house and yard on a computer. She determines that the circle that defines the part of the front yard that gets watered by the sprinkler is (x−9)2+(y+11)2=16.What is the diameter, in meters, of the circular area that gets watered by the sprinkler? 4 m 8 m 16 m 32 m

yler and Bethany have 240 feet of fencing with which to build a garden. Tyler wants the garden to be in the shape of a square, while Bethany wants it to be rectangular with a length of 50 feet and a width of 70 feet. Which design would give the maximum area for the garden? Explain. Bethany’s design would give the larger garden because the area would be 3,500 ft2. Tyler’s design would give the larger garden because the area would be 3,600 ft2. Bethany’s and Tyler’s designs would give a garden with the same area. Bethany’s and Tyler’s designs are not possible with the given amount of fencing.
