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.

Hello!
110% of 90 is: 99.
I hope this was helpful! c:
Answer:
they can stay in there for 8 hours which in all would be $93.20
Step-by-step explanation:
I didn't really know whether to do it from least to greatest or greatest to least, so I did it from least to greatest.
Steps:
1. Find a common denominator
Let's do 12
2. Convert
7/12 is already in its simplest form, so 2/3 = 8/12 and 3/4 = 9/12
3. Order
7/12, 8/12, 9/12
4. Back to original form
7/12, 2/3, 3/4
ANSWER: 7/12, 2/3, 3/4
Time = distance / speed
time = 1500/330
time = 4.55 seconds <== (thats rounded)
