Please help! Find an equation in standard form for the ellipse with the vertical major axis of length 16 and minor axis of length 4.
x^2/64 + y^2/4 =1
x^2/2 +y^2/8 =1
x^2/8 +y^2/2=1
x^2/4+y^2/64 =1

Step-by-step explanation:

Use the standard form (x−h)2a2+(y−k)2b2=1 ( x − h ) 2 a 2 + ( y − k ) 2 b 2 = 1 . If the x-coordinates of the given vertices and foci are the same, then the major axis is parallel to the y-axis. Use the standard form (x−h)2b2+(y−k)2a2=1 ( x − h ) 2 b 2 + ( y − k ) 2 a 2 = 1 .

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.
