38 x 1 = 1
38 x 0.1 = 3.8
38 x 0.01 = 0.38
The cosine equation of the attached graph is; y = 5 cos [( π/40)(x - (π/2))] + 3
<h3>How to plot a trigonometric graph?</h3>
The given parameters are:
Diameter = 10 m
Thus;
Radius; r = 5 m
Time; t = 80 s
Height above the ground, h = 2 m
The above means that:
Amplitude; A = 5 m
Period, T = 80 s
Minimum = 2 m
The cosine function is represented as:
y = a cos [k(x - d)] + c.
where;
A is amplitude
B is cycles from 0 to 2π
period = 2π/k
d is horizontal shift
c is vertical shift (displacement)
Thus;
2π/k = 80
k = 2π/80 = π/40
Where
c = Amplitude - Minimum
c = 5 - 2
c = 3
Shift to the left by π/2 gives;
d = π/2
Thus, the equation of the cosine graph is;
y = 5 cos [( π/40)(x - (π/2))] + 3

Answer:
the angle measures are 20 degrees, 24 degrees, and 136 degrees
20+(y-10)+4y=180
y=34
So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x:
Firstly, solve the parentheses:
Next, multiply 36 pi and x:
Next, subtract 24 pi on both sides:
Lastly, divide both sides by 36 pi, and your answer will be , or B.
