You can put this solution on YOUR website! Write and equation of an ellipse in standard form with the center at the origin and a height of 4 units and width of 5 units. **
 This is an equation of an ellipse with horizontal major axis of the standard form:
 (x-h)^2/a^2+(y-k)^2/b^2=1, With (h,k) being the (x,y) coordinates of the center.
 ..
 For given equation:
 Center: (0,0) (given)
 length of horizontal major axis=5=2a
 a=5/2
 a^2=25/4
 length of minor axis=4=2b
 b=2
 b^2=4
 Equation:
 x^2/(25/4)+y^2/4=1
 4x^2/25+y^2/4=1
