Which of the equations below could be the equation of this parabola? O A. y = -1/2 x2
O B. y = 1/2 x2
O C. y= 1/2 y2
O D. x= -1/2 y2

A y = -1/2 x2 Correctly answer

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
