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: 11 2.) 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 ft 3.) 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

1. (-4,5); radius: 11

              2. 8m

Step-by-step explanation: Just confirming the 1st and 3rd )

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
