y varies directly as x and inversely as the square of z calculator. y = 32 when x = 114 and z = 6. find y when x = 3 and z = 6
k = (32*36)/114= 10.1052
y = 10.1052*(3/36)= 0.8421

The other tutor goes to a lot of unnecessary work to get a decimal approximation of the answer.
From the given set of data to the new one, the value of z does not change, so the only change in the value of y is due to the change in the value of x.
y varies directly as x, so when the value of x changes by a factor of 3/114 = 1/38 the value of y changes by a factor of 1/38.
ANSWER: 32(1/38) = 32/38 = 16/19
Convert that to a decimal approximation if required or desired... but the answer in fraction form is exact.

k, variation constant
-
You were then given some values to find what is k value.
or better to try
--------which might be how you want it;
-------your variation model.
