Suppose j varies jointly with g and v, and j=1 when g=6 and v=3.
find the constant variation and find j when g=8 and v=11

The constant of variation is

Value of j is

Step-by-step explanation:

Given,

j varies jointly with g and v,

That is,

j ∝ gv

⇒ j = k(gv)

Where, k is the constant of variation,

We have, j = 1 when g = 6 and v = 3

⇒ 1 = k(6 × 3) ⇒ 1 = 18k ⇒ k =

Thus, the equation that shows the given relation in j, g and v is,

If g = 8, v = 11,
