Question

What is the major axis for the equation+= 1? Type h for horizontal or v for vertical.

Answer 1

Consider the given equation,

`\begin{gathered} (x^2)/(49)+(y^2)/(7)=1 \\ (x^2)/((7)^2)+(y^2)/((√(7))^2)=1 \end{gathered}`

This is a standard equation of a horizontal ellipse, whose semi-major axisis given as,

`a=7`

So the length of major axis will be,

`2a=2(7)=14`

Thus, the length of major axis of the given equation is 14 units.
