SAMPLE A Aunt Jackie's Ring
What is the conflict in the story?
O
A. Mary receives a very old ring.
B. Mary washes her hands.
1 For Mary's birthday, her aunt gave her a ring that was more than
100 years old. "Take good care of it," her aunt warned. Mary did
exactly that, until one day she looked down at her hand and noticed
that the ring was gone.
2 Aunt Jackie is going to be so disappointed in me, thought Mary.
Then Mary remembered she put the ring in her pocket when she
washed her hands at the sink. Thank goodness! Mary said to herself.
After that, she never took off Aunt Jackie's ring again.
OC. Mary thinks her aunt will be upset.
D. Mary thinks she has lost her ring.

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
