Find the vertex, focus, and directrix for the following parabolas.

(a)
` ( y - 5 )^(2) = 8 ( x - 5) `
vertex : 
focus : 
directrix:   

(b)
` y^(2) - 10 y = 16 x - 5^(2) ` 

vertex : 
focus : 
directrix"   

(c)
` ( x - 8 )^(2) = 16 ( y - 2 ) ` 

vertex : 
focus : 
directrix"   

(d)
` x^(2) + 16 x = 4 y - 20 ` 

vertex : 
focus : 
directrix"
