Question 258

Multiple Choice

Solve the problem.
-The ellipse x25+y211=1\frac { x ^ { 2 } } { 5 } + \frac { y ^ { 2 } } { 11 } = 1 is shifted down 6 units and right 4 units. Find an equation for the new ellipse and find the new vertices.


A) (x+4) 25+(y6) 211=1\frac { ( x + 4 ) ^ { 2 } } { 5 } + \frac { ( y - 6 ) ^ { 2 } } { 11 } = 1 ; vertices: (4,6±11) ( 4 , - 6 \pm \sqrt { 11 } )
B) (x4) 25+(y+6) 211=1\frac { ( x - 4 ) ^ { 2 } } { 5 } + \frac { ( y + 6 ) ^ { 2 } } { 11 } = 1 ; vertices: (4±5,6) ( 4 \pm \sqrt { 5 } , - 6 )
C) (x4) 25+(y+6) 211=1\frac { ( x - 4 ) ^ { 2 } } { 5 } + \frac { ( y + 6 ) ^ { 2 } } { 11 } = 1 ; vertices: (4,6±11) ( 4 , - 6 \pm \sqrt { 11 } )
D) (x6) 25+(y+4) 211=1\frac { ( x - 6 ) ^ { 2 } } { 5 } + \frac { ( y + 4 ) ^ { 2 } } { 11 } = 1 ; vertices: (4±5,6) ( 4 \pm \sqrt { 5 } , - 6 )
