Help Plz I need some help also did I forget to mention that I need help smart people where are you guys at I’m literally putting all my points on this so yeah need the right answer I put this up b4 and both we’re wrong if the people who answered my last one are here A for effort

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

part a: 1.08

part b: 27.59

the equation of the parabola is y2=12x

explanation:

the vertex is midway between the focus ad the directrix

so, the vertex is (0,0)

let p=(x,y) be a point on the parabola.

the distance of p from the directrix is equal to the distance from the focus.

x+3=√(x−3)2+(y−0)2

(x+3)2=(x−3)2+y2

x2+6x+9=x2−6x+9+y2

y2=12x

graph{y^2=12x [-10, 10, -5, 5]}
