Answer:
Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
(x -2)^2 +(y -(-1))^2 = 4^2
(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A
Answer:
The correct answer is H
Step-by-step explanation:
1/4 of a wall in 2/3 of an hour is 40 min
so a wall takes 160 min which is 2 hours and 40 min
so 3 walls takes 8 hours
Answer: 8 feet
Step-by-step explanation:
Ok so first you turn 2 Yards into feet because the answers are all in feet by multiplying by 3/1 so it would look like this 2/1x3/1 which is 6 then you use proportion to get the 6 yards by it self so it would look like this 48/6 6/6 the you would get x= 8 feet to get 8 feet you dividied 48 by 6 hope this helps
