SOLUTION: at the waters surface, air exerts 1 atmosphere (atm) of pressure. under water, the pressure increases. The pressure P (atm) varies with depth d(ft) according to the equation P=(d/3

Question 705333: at the waters surface, air exerts 1 atmosphere (atm) of pressure. under water, the pressure increases. The pressure P (atm) varies with depth d(ft) according to the equation P=(d/33)+1. Boyles law says the volume V of air varies inversely with the pressure P. If you hold yur breath the volume of air in your lungs increases as you ascend. when have 4 qt air in lungs at a depth of 66 ft (P=3atm), the air will expand to 6 qt when you reach 33 ft, where P=2atm.
* make graph&table to show how volume of air in your lungs varies with depth.
* make table&graph to show how volume of air in lungs varies with pressure.. please help!

Use the two-point form of an equation of a line to derive the volume as a function of depth equation. The two points being (66,4) and (33,6).
Then use the two-point form again to derive the volume as a function of pressure equation with the points (3,4) and (2,6).
Two Point Form
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Once you have done the arithmetic to simplify your equations, a graph and a table is trivial.
