a Answer the following:
1. If a varies directly as b, give the equation of variation?
2. If a varies inversely as the square of b, and a = 6 when b = 3. Find k?
3. If a varies directly as the square of b, what is a when k = 4 and b = 3?
4. If a varies inversely as the cube of b, and a = 5 when b = 2, what is a when b = 4?
5. If a varies directly as the square of b, and a = 16 when b = 8
a. find a in terms of b.
b. find b when a = 4.
