It is given that varies directly as
and inversely as the square of
, and that
when
and
. Then, when
and
,
equals:
Solution 1:
varies directly to
(The inverse variation of y and the square of z)
We can write the expression
Now we plug in the values of when
and
.
This gives us
We can use this to find the value of when
and
Simplifying this we get,
