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

Okay so there are 100 white balloons, 200 pink balloons, and we are specified that the ratio of pink to yellow is 10:1 soo we can plug 200:20 which can be simplified to 100:10 which can then be simplified to 10:1 there is our ratio. So there are 29 yellow balloons. Therefore there are only 80 balloons left which would mean there are 80 blue balloons!:)
