Answer:
The model is
.
Step-by-step explanation:
Consider the given information.
The volume of air inside the lungs increases or decreases so for this we will use the basic sine function
as our parent function.
Let us assume that the phase shift is 0 it means
.
The air that moves into and out of the lungs is about 498 mL.
It means the amplitude of the function will vary by 249(half of 498).
The reserve and residual volumes of air that remains in the lungs occupy about 1990 mL which is the minimum air in the lungs.
So, the max air will be: 1990+498 =2488 mL
And the average will be d=1990+249=2239 ml
The horizontal stretch will be
as we know that period of
is
and respiratory cycle for an average human takes about 4 seconds.
Hence, the model is
.
The answer is 46. .1 times 200 is 20. then .23 times 200 is 46
