Answer:
D- It would quadruple
Step-by-step explanation:
Answer:
<em>C/Point B is between points A and C</em>
Step-by-step explanation:
<em> </em><em>When graphed, the lines are parellel.</em>
25% = 85 / 4 = $21.25 off
5% = 85 / 20 = $4.25
75% = 21.25 • 3 = $63.75
$63.75 + $4.25 = $68
Her total bill was $68
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.
