For a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. the function v=18000/p relates the volume in cubic inches and pressure in pounds per square inch of a gas. what is the volume when the pressure is 900 pounds per square inch?

Volume of the gas is 20 cubic inches.

Step-by-step explanation:

Inverse proportion: Let x and y be two quantities are said to be inverse proportion or inversely proportional if one quantity increases at the same rate the other decreases.

or

⇒   where k is constant.

Since, it is given that the volume of gas is inversely propotional to its pressure.

Given the function:  

          ......[1] ; where volume in cubic inches and pressure in pounds per square.

To find the volume in cubic inches.

The pressure (p) = 900 pounds per square inch.

Substitute the value of p in [1];

Therefore, the volume(v) = 20 cubic inches when the pressure is 900 pounds per square inch.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
