Q. q varies directly with p2.When q=36,p=12Find a formula connecting q and p.q=θSubmit Answer
Establish direct variation relationship: Establish the direct variation relationship.Since q varies directly with p2, the relationship can be expressed as q=kp2, where k is the constant of variation.
Find k using given values: Use the given values to find k. We know q=36 when p=12. Substitute these values into the equation q=kp2. 36=k(12)2
Solve for k: Solve for k.Calculate 122=144.Then, 36=k×144.Divide both sides by 144 to isolate k.k = 14436k = 0.25
Write formula connecting q and p: Write the formula connecting q and p. Substitute k=0.25 back into the direct variation equation. q=0.25p2
