Question 472765
Find the length of the major and minor axes for this ellipse.? 
1.) (x^2/16)+(y^2/25) = 1
---
Half of the major axis is sqrt(25) = 5
So, major axis is 2*5 = 10
---
Half of the minor axis is sqrt(16) = 4
So, minor axis is 2*4 = 8
=========================================== 
2.) (x^2/100)+(y^2/25) = 1
Similarly, major = 2*sqrt(100) = 2*10 = 20
minor = 2*sqrt(25) = 2*5 = 10
===========================================
3.) x^2+4y^2=33
---
(x^2/33) + (y^2/(33/4)) = 1
----
major = 2*sqrt(33)
minor = 2*sqrt(33)/2 = sqrt(33)
==================================
