What is the length of the major axis? x^2/16+y^2/25=1
1 answer:
The general equation of an ellipse is
x^2 y^2
--- + ---- = 1
a^2 b^2
where a or b is the semi-major axis depending on values of a^2 and b^2.
So for our ellipse major axis = 2b and b^2 = 25 and b = 5
And major axis = 2b = 2*5 = 10 answer.
