find a mathematicl model representing the statement. (Determine the constant of proportionality) v varies jointly as p and q and inversely as the square of s. (v=1.6 when p=4.1, q=7 and s=1.3

Step-by-step explanation:

If v varies jointly as p and q, this means that v varies directly as the product of p and q as shown;

... 1

k = constant of proportionality

Also v varies inversely as the square of s; mathematically,

Equating 1 and 2, we have;

Given v = 1.6, when p=4.1, q=7 and s=1.3

The constant of proportionality is 0.09422

The expression therefore becomes

50x5=$250
