Q. If p and q vary inversely and p is 30 when q is 11 , determine q when p is equal to 33 .Answer:
Understand Relationship: Understand the relationship between p and q. Since p and q vary inversely, we can write the relationship as p=qk, where k is the constant of variation.
Find Constant of Variation: Use the given values to find the constant of variation k. We know that p=30 when q=11. Substitute these values into the inverse variation equation p=qk. 30=11k
Solve for k: Solve for k.Multiply both sides by 11 to isolate k.30×11=kk=330
Write Inverse Variation Equation: Write the inverse variation equation with the found value of k. Now that we have k=330, the equation becomes p=q330.
Find q for p=33: Find q when p is equal to 33. Substitute p=33 into the equation p=q330. 33=q330
Solve for q: Solve for q.Multiply both sides by q and then divide by 33 to isolate q.33q=330q=33330q=10
