Question

.............:D

Answer 1

I saw this question earlier and it couldn't be answered because we didn't know how high above the ground point A is. Are you saying by A(8), that it is 8 m up?

Answer 2

yes, do you know what equation to use to figure it out? :/

Answer 3

Yes, but can't do it without the coordinates of that third point.
So that is "yes" point A is 8m up?

Answer 4

Yes, ok, we're in business.
You have three points on a parabola
(0,1.39)
(18,8)
(45,0)
You can use the standard form of a quadratic,
y=ax^2+bx+c, and plug in each point to solve for a, b, and c.

Answer 5

You'll have to solve a system of two linear equations to get a and b.

Answer 6

Once you have the equation for the parabola, find the vertex.

Answer 7

Oh okaay :) Thank you soo muchh! I understand it now

Answer 8

are you still there? haha .. i have no idea how to work this :// but i need to ask you something

Answer 9
