Considering the period of the cosine function, it is found that it takes 40 seconds for the wheel to complete one turn.
<h3>What is the period of the cosine function?</h3>
The cosine function is defined by:
f(x) = acos(bx + c) + d.
For the period, we have to look at coefficient b, and the period is:
P = 2π/|B|
For this problem, the function is given by:
h(x) = 15 cos(π/20)
Hence B = π/20, and the period is:
P = 2π/|B| = 2π/(π/20) = 2 x 20 = 40 seconds.
Hence it takes 40 seconds for the wheel to complete one turn.

It’s A. An quadrilateral has four sides and four angles.
Answer:
x=6
Step-by-step explanation:
Goal: "solve for x" in 3 - 2x = -1.5x.
First: Add 2x to both sides to isolate x:
3 = 0.5x
Next, divide both sides by 0.5, again to isolate x:
3/0.5 = x, or x = 6
