Answer:
Step-by-step explanation:
Given that:
As we know that the Parabola is of type
:
= -4a(y - ) where: is the origin of the line so we have:
and
<=> = -4a(y-20)
at y = 0, we have:
= -4a(0-20)
<=>
<=> x = ±
But we know that 2x= 80 <=> x= 40, so:
40 =
<=> 1600 = 80a
<=> a = 20
The equation for the parabola is:
It's height from the center at x= 0 => y= 20
