Find the standard form of the equation of the parabola with a focus at (0, 5) and a directrix at y = -5. (5 points)
select one:
a. y = 1/5 x2
b. y = 1/20 x2
c. y2 = 5x
d. y2 = 20x

step-by-step explanation:

try remembering the steps

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

the answer is 13/48

step-by-step explanation:

where is the option given
