SOLUTION: Assume that the trajectory in a javelin throw is parabolic and that it can be described using the equation: 200𝑦 = 80𝑥 − x^2 where 𝑥 is the horizontal distance, 𝑦

Question 1194414: Assume that the trajectory in a javelin throw is parabolic and that it can be described
using the equation:
200𝑦 = 80𝑥 − x^2
where 𝑥 is the horizontal distance, 𝑦 is the height. Both measurements are in meters. what is the brand
reached?

==============
IDK what you mean by "brand."
A previous posting said "mark."
Maybe it's a language thing.
-----------------------------
It's a parabola.
y = 0 at x = 0, and at x = 80, so 80 is the distance to impact.
------
The max height is halfway, at x = 40
Sub 40 for x to find max height.
