The answer is 4.
The easiest way to determine the value of statements like this is to turn the percentage into a decimal and then multiply.
20% * 20
.20 * 20
4
Answer:
.20
Step-by-step explanation:
75/500 = .15
35-15=20
You subtract 6 every time. So, there are already 3 terms, so we need to find the next 19. We can do 19x6, which equals 114. Then subtract 114 from 7, which is -107.
So, the 22nd term will be -107. Hope this helps :)

Step-by-step explanation:
<u>Function Modeling</u>
Since the air in the lungs goes periodically from a minimum value to a maximum value, we can simulate its behavior as a sinusoid. Selecting a sine or a cosine will depend on the initial condition we'll assume since the question doesn't provide one. We'll set the initial state when the lungs are at maximum air content. The sinusoid that starts from maximum is the cosine, so our model is

Where Ao is the amplitude of the oscillation, w is the angular frequency and M is the midline or y-displacement of the wave.
The values of A run from a min of 3.5 to a max of 4.5. That gives us twice the amplitude, thus

The vertical displacement or midline can be found as the shift from the center value:

We also know the cycle repeats 6 times per minute. If the time is expressed in minutes, then the frequency is f=6
Knowing that

Then

The model is

where t is expressed in minutes
