Hello there.
00:02
In this question, we're just asked to graph an equation, and the equation is written out for you here.
00:09
It's x squared over 25 plus y squared over 4 equals 1.
00:15
And i went ahead and graph this using an online grapher.
00:18
You can use that, or you can use a grabbing calculator, or you can do it manually.
00:24
But i'll walk you through some important parts here.
00:28
So this is already written out for us pretty much in standard form.
00:32
If we write the standard form or an ellipse, it's going to be x minus h squared over a squared plus y minus k squared over b squared equals.
00:57
So this is already pretty much in standard form.
01:00
Like i said, in this case, we have, since we have, since we have.
01:08
Have x squared and y squared without you know without any other terms we know that h and k are zero so the center of this ellipse is at zero zero so you can see that right here it's centered at the origin at zero zero and then a squared is 25 so a it's going to be the square root of 25 or 5 and then b squared is four so b is going to be a square a four or two.
01:45
So a and b are the horizontal radius and then the vertical radius.
01:52
So we should see that the horizontal radius is five.
01:54
Let's check here...
