Z varies directly as the square of
x
and inversely as
y
.If z = 18 when x = 3 and y = 3. Find z when x = 8 and y = 4.

9/10 divide by -3/15 as a mixed number

An incoming airplane is x miles due north from the control tower at an airport. a second incoming airplane is y miles due east of the same control tower. the shortest distance between the two airplanes is z miles. which of the following functions would best model the situation above?
