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)
You are told that sprinklers run for the same amount of time. lets refer to this time as T.
you are told that 4 sprinkles run one at a time for 50 minutes total. that means that T should be 50/4 = 12.5 minutes = 12 minutes and 30 seconds
Answer: you need to keep dividing

The answer is B) G = 2E +3
Answer:
The set
Step-by-step explanation:
We separate the left and right side of the equation, to create two new equations:
(1)
(2).
and then to solve Tanisha's original equation, we find the solution to the system that we got above.
The first step in solving the above system of equations is to take the value for 
from equation(1), and substitute it into equation(2) which gives us:
which is the same equation that Tanisha set out to solve.
