We are told that X is inversely proportional to the square of Y. So...
or...
Let us use the first of the two options.
If x=8, then
And...
Now we will raise our value of Y by 200%...
Now just a little algebra...
Then..
After raising Y by 200%, the value of X is...
And comparing this to our first value of x, we find that when X=8, and then Y is raised by 200%, X is DECREASED by Approximately 82.3 %.
Check your answer!
I hope this helps! Learn on!
