Write an equation of the parabola with vertex (0 0) and directrix x=-6

y^2= -24x

Step-by-step explanation:

The . of the Parabola having the Vertex at the Origin

0(0, 0) and the Directrixd: z + a = 0, is, y> = 4az.

From this follows the desired . of the Parabola :

graph{y”2=-24x [-40, 40, -20, 20]} y2 = — 24x.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
