Question 90

Multiple Choice

Write the equation of the ellipse in standard form. Identify the vertices and foci.
- 36x2+25y2+100y+99=036 x ^ { 2 } + 25 y ^ { 2 } + 100 y + 99 = 0


A) x2136+(y+2) 2125=1\frac { x ^ { 2 } } { \frac { 1 } { 36 } } + \frac { ( y + 2 ) ^ { 2 } } { \frac { 1 } { 25 } } = 1
vertices: (95,0) ,(115,0) \left( - \frac { 9 } { 5 } , 0 \right) , \left( - \frac { 11 } { 5 } , 0 \right)
foci: (2+1130,0) ,(21130,0) \left( 2 + \frac { \sqrt { 11 } } { 30 } , 0 \right) , \left( 2 - \frac { \sqrt { 11 } } { 30 } , 0 \right)
B) x2136+(y+2) 2125=1\frac { x ^ { 2 } } { \frac { 1 } { 36 } } + \frac { ( y + 2 ) ^ { 2 } } { \frac { 1 } { 25 } } = 1
vertices: (0,95) ,(0,115) \left( 0 , - \frac { 9 } { 5 } \right) , \left( 0 , - \frac { 11 } { 5 } \right)
foci: (0,2+1130) ,(0,21130) \left( 0,2 + \frac { \sqrt { 11 } } { 30 } \right) , \left( 0,2 - \frac { \sqrt { 11 } } { 30 } \right)
C) 36x2+25(y+2) 2=136 x ^ { 2 } + 25 ( y + 2 ) ^ { 2 } = 1
vertices: (36,2) ,(36,2) ( 36 , - 2 ) , ( - 36 , - 2 )
foci: (0,2+1130) ,(0,21130) \left( 0,2 + \frac { \sqrt { 11 } } { 30 } \right) , \left( 0,2 - \frac { \sqrt { 11 } } { 30 } \right)
D) 36x2+25(y+2) 2=136 x ^ { 2 } + 25 ( y + 2 ) ^ { 2 } = 1
vertices: (0,95) ,(0,115) \left( 0 , - \frac { 9 } { 5 } \right) , \left( 0 , - \frac { 11 } { 5 } \right)
foci: (0,2+1130) ,(0,21130) \left( 0,2 + \frac { \sqrt { 11 } } { 30 } \right) , \left( 0,2 - \frac { \sqrt { 11 } } { 30 } \right)
