Try another version of this question Suppose that `z` varies jointly with `x` and `y` . Find the constant of proportionality `k` if `z = 206.4` when `y = 3` and `x = 16` . Using the `k` from above write the variation equation in terms of `x` and `y` . Using the `k` from above find `z` given that `y = 11` and `x = 29` .
`k =`
`z =`
`z =`
If needed, round answer to 3 decimal places.
