Answer:
AB = 7√2
Step-by-step explanation:
if a(x1,y1) and b(x2,y2) then

Based on your points and on the formula above AB is:

I think it’s the second option
Answer:
8
Step-by-step explanation:
You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a. Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet
