Y=-0.05x^2+4.5x-6.5 pls help to solve
givi [52]
Following with the extra hint that x = 82.03 m

There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:

Plug x = 82.03

=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
         = -336.446045 + 369.135 - 6.5
         = 26.188955 m

Please take the time and understand the answer instead of just looking at the final result.

Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>

If you look at the data, you can see that every y value is opposite to the corresponding x- value.

So, equation can be written as

y = [-] x or y=[-1]x
