Identify the Foci and Write Equations for the Asymptotes 9(y4)2100(x+4)2=9009 ( y - 4 ) ^ { 2 } - 100 ( x + 4 ) ^ { 2 } = - 900

Question 32

Multiple Choice

Identify the foci and write equations for the asymptotes.
- 9(y4) 2100(x+4) 2=9009 ( y - 4 ) ^ { 2 } - 100 ( x + 4 ) ^ { 2 } = - 900


A) foci: (4+109,4) ,(4109,4) ( - 4 + \sqrt { 109 } , 4 ) , ( - 4 - \sqrt { 109 } , 4 )
asymptotes: y=103x+523y = \frac { 10 } { 3 } x + \frac { 52 } { 3 } and y=103x283y = \frac { 10 } { 3 } x - \frac { 28 } { 3 }
B) foci: (0,4+109) ,(0,4109) ( 0 , - 4 + \sqrt { 109 } ) , ( 0 , - 4 - \sqrt { 109 } )
asymptotes: y=310x145y = \frac { 3 } { 10 } x - \frac { 14 } { 5 } and y=310x265y = - \frac { 3 } { 10 } x - \frac { 26 } { 5 }
C) foci: (4+109,0) ,(4109,0) ( 4 + \sqrt { 109 } , 0 ) , ( 4 - \sqrt { 109 } , 0 )
asymptotes: y=103x283y = \frac { 10 } { 3 } x - \frac { 28 } { 3 } and y=103x+523y = \frac { 10 } { 3 } x + \frac { 52 } { 3 }
D) foci: (0,4+109) ,(0,4109) ( 0,4 + \sqrt { 109 } ) , ( 0,4 - \sqrt { 109 } )
asymptotes: y=310x+265y = \frac { 3 } { 10 } x + \frac { 26 } { 5 } and y=310x+145y = - \frac { 3 } { 10 } x + \frac { 14 } { 5 }
