For this exercise, let's start off by considering this information found here.
00:05
We're told that the variable y varies inversely with both x and the square root of z.
00:14
From this information, we can write the equation that y is equal to the proportionality constant k, and now go to the keyword where y varies inversely.
00:25
When we say varies inversely, it means that both x and the square root of z, which is root z, will be placed in the denominator.
00:34
So the equation is that y equals k divide by x times the square root of z.
00:41
This is our equation so far, and the last step is going to be to determine the value of this constant k.
00:48
To find that constant, let's go to this set of information here...
