4, 2, 1, 3
we cannot use 2 before having another triangle, so 4 must be before 2
we can use 1, but it will be just a restatement of the given information is not done before 4 and 2
3 is the final goal, which is always the last step
<span>The equation given as p varies directly with d and inversely with the square root of u is written as:
</span>
p = k1d
k1 is the proportionality constant.
and p = k2

here k2 is the proportionality constant.
Thus,
combining both equations we get, p = C

where K = K1*K2, K is the proportionality constant.
