Answer:
3 unit is the correct answer
the shape of the telescope is said to be a parabola. In this case, t<span>he general form which we will pattern our equation is y- k= 4a(x – h)^2
(h,k) or vertex = (0,0)
y = 4ax^2
We substitute x = 320/2 = 160, y = 46
46 = 4a (160)^2
46 = 4a (25600)
4a = 23/12800
hence the equation is </span>y = (<span>23/12800)</span>x^2
Answer: (16, 24)

Hope this helps , good luck with the rest!
If your bottom time is 25 minutes, general rules recommend that you ascend immediately to 15 feet then remain there for 8 minutes. You should then go to the surface and not dive for 6 hours.
<h3>What do general rules on diving say about a 25 minute bottom time?</h3>
The recommended bottom time is 24 minutes which means that staying there for 25 minutes will have exceeded this recommendation.
You should immediately ascend to 15 feet or 5 meters, and then wait there for 8 minutes. Then return to the surface and avoid diving for the next 6 hours.
