question 2

Multiple Choice

Graph the ellipse. Specify the lengths of the major and minor axes, the foci and the eccentricity. $9 x ^ { 2 } + 16 y ^ { 2 } = 144$

• A) length of major axis: 8; Length of minor axis: 6; Foci: \(( 0 , \pm \sqrt { 7 } )\) ; Eccentricity: \(\frac { \sqrt { 7 } } { 4 }\)
• B) length of major axis: 4; Length of minor axis: 3; Foci: \(( 0 , \pm \sqrt { 7 } )\) ; Eccentricity: \(\frac { \sqrt { 7 } } { 4 }\)
• C) length of major axis: 9.6; Length of minor axis: 7.2; Foci: \(( 0 , \pm \sqrt { 7 } )\) ; Eccentricity: \[\frac { \sqrt { 7 } } { 4 }\]
• D) length of major axis: 8; Length of minor axis: 6; Foci: \(( \pm \sqrt { 7 } , 0 )\) ; Eccentricity: \(\frac { \sqrt { 7 } } { 4 }\)
• E) length of major axis: 4; Length of minor axis: 3; Foci: \(( \pm \sqrt { 7 } , 0 )\) ; Eccentricity: \(\frac { \sqrt { 7 } } { 4 }\)
