The answer is x=9 hope this helps!!
Answer:
8 ft
Step-by-step explanation:
h(x)=-0.0085x²+0.25x+6,
The maximum height will be at the vertex
The x coordinate is at
h = -b/2a where b is the x term coefficient and a is the x^2 term coefficient
h = -(.25)/(2(-.0085)
=14.70588235
We want to find the height so we need to substitute this into the equation
h(14.70588235)=-0.0085(14.70588235)^2+0.25(14.70588235)+6,
=-1.838235294+3.676470588+6
=7.838235293 ft
To the nearest foot
= 8 ft
C. 4 because 4 is a perfect square, as well as x^2 and 4x
I hope that helps!
