You need to find the vertex of the function.
The easiest way to do this is to graph it on a calculator like desmos.
but you can find the line of symmetry with this equation. x=-b/2a
x=-112/2(-16)
x= 3.5
Then plug that into the equation.
-16(3.5)^2+112(3.5)+30
226
226ft is the maximum height.
You can write both numbers as fractions:
Dividing by a fraction is the same as multiplying by its inverse, so we have
We can cross-simplify the 10's and we have
Answer:
Simplify the expression.
