Question 255

Multiple Choice

Write the given equation in the form (xh) 2+(yk) 2=r2( x - h ) ^ { 2 } + ( y - k ) ^ { 2 } = r ^ { 2 } . Identify the center and radius.
- x2+y2+8x10y+25=0x ^ { 2 } + y ^ { 2 } + 8 x - 10 y + 25 = 0


A) (x+4) 2+(y5) 2=16( x + 4 ) ^ { 2 } + ( y - 5 ) ^ { 2 } = 16
Center: (4,5) ;r=4( 4 , - 5 ) ; r = 4

B) (x+4) 2+(y5) 2=16( x + 4 ) ^ { 2 } + ( y - 5 ) ^ { 2 } = 16
Center: (4,5) ;r=4( - 4,5 ) ; r = 4

C) (x+8) 2+(y10) 2=25( x + 8 ) ^ { 2 } + ( y - 10 ) ^ { 2 } = 25
Center: (8,10) ;r=25( 8 , - 10 ) ; r = 25

D) (x+8) 2+(y10) 2=25( x + 8 ) ^ { 2 } + ( y - 10 ) ^ { 2 } = 25
Center: (8,10) ;r=25( - 8,10 ) ; r = 25
