The foci of an ellipse lie on the major axis of the ellipse

Answer with explanation:

Equation of ellipse in two forms

So, there are two cases.

1. When , a > b

Major Axis = X axis

Minor Axis =Y axis

Focus , lies on the Major Axis that is on X axis.

2. When, a < b

Major Axis = Y axis

Minor Axis = X axis

Focus lies on the Major axis, which is Y axis.

So, In both the cases ,the Focus lies on Major Axis.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
