If Y varies inversely with the square of x. When x is 5, y is 4/5, how do you find value of y, when x equals 8?
Set up the described equation, solve it for the proportionality constant, and then use your completed equation to calculate the new value.
First, set up the described equation.
Then, given x = 5 and y = 4/5 we can solve for the proportionality constant of the equation.
SO, our equation is
