Question 94

Multiple Choice

Identify the vertices and the foci.
- x2(y+5) 23=1x ^ { 2 } - \frac { ( y + 5 ) ^ { 2 } } { 3 } = 1


A) vertices: (1,5) ,(1,5) ( 1,5 ) , ( - 1,5 )
foci: (2,5) ,(2,5) ( 2,5 ) , ( - 2,5 )
B) vertices: (1,5) ,(1,5) ( 1 , - 5 ) , ( - 1 , - 5 )
foci: (2,5) ,(2,5) ( 2 , - 5 ) , ( - 2 , - 5 )
C) vertices: (0,5+3) ,(0,53) ( 0 , - 5 + \sqrt { 3 } ) , ( 0 , - 5 - \sqrt { 3 } )
foci: (0,7) ,(0,3) ( 0 , - 7 ) , ( 0 , - 3 )
D) vertices: (0,5+3) ,(0,53) ( 0,5 + \sqrt { 3 } ) , ( 0,5 - \sqrt { 3 } )
foci: (0,7) ,(0,3) ( 0,7 ) , ( 0,3 )
