Step-by-step explanation: ur telling me this is highschool math? lol. im in middle school but took this stuff in third grade.
Answer:
See attached for a graph
Step-by-step explanation:
We're going to plot sea level as y=0 and a depth of 8 meters as y=-8.
The problem statement tells you the initial point (x=0) is at normal ocean depth (y=-8), so the first point you put into your sine tool is ...
(x, y) = (0, -8)
The buoy takes 16 seconds to go from a high point to a low point, so the time to the first high point is half that, or x=8 seconds. That high point is 5 meters above its average depth, so is at y=-3.
The second point you will put into your sine tool is ...
(x, y) = (8, -3)
4(x+9)

Square part of perimeter = 40.
Half circle = 25.135.
Together 65.135 is perimeter.
Area of square: 192
Are of half circle: 100.53.
Together 292.53
Rounded =292.48 I guess, its the most logical option since I don't see it and the only one that fits perimeter answer.
So its the 3rd question I believe, you may want to double check.
