Question

Use the given information to find the unknown value. Y varies inversely with the cube of x. When x=5, then y=1. Find y when x=1

Answer 1

Answer:

125

Step-by-step explanation:

y = 1k/x^3  I am trying to find the constant k.  I will use the information that I have been given to find k

1 = k/5^3

1 = k/125  Multiply both sides by 125

125 = k

Now, we will find y when x = 1

y = 125/1^3

y = 125
