Step-by-step explanation:
If the parabola has the form
 (vertex form)
 (vertex form)
then its vertex is located at the point (h, k). Therefore, the vertex of the parabola

is located at the point (8, 6).
To find the length of the parabola's latus rectum, we need to find its focal length <em>f</em>. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is 

where  is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length <em>f</em> is
 is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length <em>f</em> is 

By definition, the length of the latus rectum is four times the focal length so therefore, its value is

 
        
             
        
        
        
So say we have the number: 54,321
The 5 would be worth 50,000 meaning it's in the ten thousands place. 
The 4 would be worth 4,000 meaning it's in the thousands place. 
. 
The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place
. 
Hope that helps :)
