Answer from: Quest

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

 

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

 

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

 

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

 

la fórmula de la directriz

es x + p = 0

 

resolviendo:

 

y^2-9x = 0

y^2 = 9x

 

4p = 9, entonces p = 9/4

 

entonces el foco tendrá la

coordenada f(9/4,0)

 

la directriz vendrá

expresada por

 

x + p = 0

x = -p

x = -9/4

 

el problema indica que la

ordenada es igual a 6, entonces

 

(6)^2=9x

x = 36/9

x = 4

 

entonces el punto al cual

hay que obtener la distancia será p(4,6)

 

calculando se tendrá: pf = 

pf = 6,25 u
