Answer:
<h2>pretty sure its A sorry if its wrong </h2>
Step-by-step explanation:
Since we are dealing with a radical then x - 5 ≥ 0, for real values
x = 4 is less than 5 , hence is not in the domain
392 millimeters I think that's the answer but I'm not sure
Answer: 36x^2

Hi! I usually hate to use links, but I actually just answered this same question for someone else. I would copy and paste, but my copy and paste is screwing up the format making it super hard to read. I'm attaching the link instead. Hope this helps!

Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
