1. the pressure of a gas p(v) varies inversely with the volume of the gas v. the pressure v. the pressure of a gas measures 15kg/cm2 when its volume is 300 cm3.
which equation can be used to find the pressure of the gas when the volume is changed?
a.) p(v) = 20v
b.) p(v) = 20/v
c.) p(v) = 4500v
d.) p(v) = 4500/v
2. the function f(x) varies inversely with x and f(x) =8 when x =3.
what is f(x) when x = 2?
a.) 12
b.) 14
c.) 22
d.) 48
