the hamburger i can answer. 

 

Grill it until its not pink on the inside and until it is nice and greasy. If you don´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
