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

Step-by-step explanation:
Answer:
2.48$
Step-by-step explanation:
You can say that the tip is ? of of 13.75 and written as
and .18 is cross multiply these so
13.75 x 18 = 100?
247.5 = 100?
2.475 = ?
then round up
