I need help please asap!

You know three points on the parabola: (0,0), (150,30), (-150,30) (I’m guessing about the 30. The picture is not clear enough on my phone.)

The parabola is vertical, so its equation has the form y = a(x-h)^2+k, where (h,k) is the vertex.

The vertex is (0,0), so y = ax^2.

Plug another point into the equation and solve for a:

30 = a150^2

a = 30/150^2 = 1/750

y = Height of cable at a point x feet from center.

y = (1/750)x^2

21/58.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
