The first and second coordinate points of the sine graph are;
(0, 20) and (2, 22)
<h3>Sine Graph expression</h3>
The general formula we will use to plot the graph is;
y = [Asin (2πx/t)] + ∅ (Note that sin is in radians)
where;
A is amplitude
t is period
∅ is phase shift
We are told that the buoy bobs up and then down 2 meters from the ocean's depth. This means that;
Amplitude; A = 2
Now, Four seconds pass from the time the buoy is at its highest point to when it is at its lowest point. Thus;
Period = 2 * 4 = 8 seconds
Assume at x = 0, the buoy is at normal ocean depth. Thus;
Phase shift; ∅ = 20
Thus, we have;
y = [2sin((2πx/8)] + 20
At x = 0, we have;
y = [2sin((2π*0/8)] + 20
y = 0 + 20
y = 20
Thus, first point is; (0, 20)
Since the second point must be a maximum or minimum value on the graph closest to the first point, then we put 2 for x to get the coordinate of the second point;
y = [2sin((2π*2/8)] + 20
y = [2sin((2π*2/8)] + 20
y = [2sin(π/2)] + 20
In radians, sin(π/2) = 1. Thus;
y = (2 * 1) + 20
y = 22
Second point is (2, 22)
Using the first and second point coordinates, we will use sine tool to graph the function as attached below.

Answer:
Explanation:
Given
x is a factor
Required
Solve for k
x is a factor means that the polynomial can be divided successfully by x.
In other words, x is a zero of the polynomial.
i.e.
and
Substitute 0 for x in P(x)
Substitute 0 for P(x)
Collect Like Terms
Divide both sides by 5
Answer:
0.2776
Explanation:
Mean = 15000, SD = 1500
We need to find Cumulative probability: P(X > 15884)
First we need to convert it into normal distribution.
From the attached file, we can see the shaded area we are looking for.
For conversion as follow;
Next to find Z = = 0.59
now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).
P(X > 15884) = P(Z > 0.59).
From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.
