**NEED HELP??!!! Two Urgent Mathematical Questions!!!

  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

  1. 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

Verified Answer :

The correct answer to question 1 is: (C. P (v)=4500v
The correct answer to question 2 is: (A. 12

Hope i helped!:)
