The pressure of a gas p (v) varies inversely with the volume of the gas v. the pressure of a gas
measures 25 kg/cm² when its volume is 200 cm
which equation can be used to find the pressure of the gas when the volume is changed?
op(u) = 5
o p (v) = 5000
op() = 80
op(u) = 5 to

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?
