Part a) Write the equation of inverse variation that relates x and y. Begin by writing the general formula of inverse variation which is y = {k \over x}. This gives us the idea that we can solve for k since the values of x and y are given.
The volume V varies inversely as the pressure P means when the volume increases, the pressure decreases and when the volume decreases, the pressure increases. Now write the formula for inverse variation. PV = k. Substitute 240 for V 30 for P in the formula and find the constant. ( 240) ( 30) = k. 7200 = k.
Solve inverse variation problems Water temperature in an ocean varies inversely to the water’s depth. Between the depths of 250 feet and 500 feet, the formula [latex]T=\frac{14,000}{d}[/latex] gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface.

Inverse variation type word problems encompass one variable, which is inverse proportional to another variable: y = k/x, where k is referred to as the constant of proportionality. Direct variation word problems often contain verbiage such as: "varies inversely as". " varied inversely as".
Example 3: Solving an Inverse Variation Problem A quantity y varies inversely with the cube of x. If y = 25 when x = 2, find y when x is 6. Solution The general formula for inverse variation with a cube is \displaystyle y=\frac {k} { {x}^ {3}} y = x 3 k . The constant can be found by multiplying y by the cube of x.
