Question

The ellipse ^2/9 + ^2/4 =1, has its major axis length equal toa.13b. 9 c. 4 d. 3 e. 6

Answer 1

The given equation of ellipse is,

`\begin{gathered} (x^2)/(9)+(y^2)/(4)=1 \\ (x^2)/(3^2)+(y^2)/(2^2)=1 \end{gathered}`

Thus, the major axis length can be determined as,

`2a=2*3=6`

Thus, option (e) is correct.
