Answer:
Center (4,1)
Radius r = 4
Step-by-step explanation:
Complete the square to fill in the standard circle equation:
- , (h,k) is the center, r is the radius
Use formula:
therefore,
(h,k) = (4,1)
r = 4
Answer:
edit: I read that wrong, sorry.
160% of 19 = 30.4
Area=LW
L=6+2W
given
A=2808
subsitute
2808=LW
subsitute 6+2W for L
2808=(6+2W)(W)
2808=2W²+6W
divide both sides by 2
1404=W²+3W
minus 1404 from both sides
0=W+3W-1404
farctor, what 2 numbers multiply to get -1404 and add to get 3
-36 and 39
0=(W-36)(W+39)
set each to zero
0=W-36
36=W
0=W+39
-39=W
false, can't have negative dimentions
W=36
L=6+2W
L=6+2(36)
L=6+72
L=78
the length is 78ft
the width is 36ft
0=
