the hamburger i can answer. 

 

Grill it until its not pink on the inside and until it is nice and greasy. If you donĀ“t like greasy hamburgers then push it down with the spatula twice every flip

We have

 

4px  =  y^2         p  = distance between the origin and  the directrix

 

4(5/2)x = y^2             

 

10x = y^2

 

x  = (1/10)y^2

 

 

cool cool cool
