Variation and Problem Solving – Section 8

Suppose a varies jointly with c2 and m, and a = 12 when c = 2 and m = 9. Find m when a = 15 and c = 3. Your Turn: Suppose a varies jointly with b and c. If a is 45 when b is 5 and c if 3, find the constant of variation and the joint variation equation. Example 7: Suppose y is directly proportional to x2 and inversely proportional to z. ................
