The volume of air in the lungs during normal breathing is a sine function of time. The volume of air in a person’s lungs varies from 2.2L to 2.8L during normal breathing. Suppose a normal breath takes 4 seconds, and that t = 0 corresponds to the minimum volume. A. Draw a graph of V against t for 10 seconds, where V is the millilitres of air in the person’s lungs

B. Write an equation for the function.

C. Explain how the graph would change if the person breathes more rapidly.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

answer: get jesus in your life

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
