For a fixed amount of a gas at a constant
temperature, the volume of the gas is inversely
proportional to its pressure. At a pressure of 30
pounds per square inch (psi), a gas has a volume
of 600 in.3.
Which function can be used to model the volume
of the gas y, in cubic inches, when the pressure is
x psi?
what would the volume of the gas be if the pressure is increased to 40 P

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
