n girl grew steadily between the ages of 3 and 12 years, gaining 5 pounds each year. Let W be the girl's weight, in pounds, as a function of her age t, in years, 12. (a) Is W a linear function or an exponential function? O linear O exponential Explain your reasoning. Since the girl grew steadily at a rate of 5.5 pounds per year, the weight, W has a--Select--- v rate of change, and thus is a --Select--- v function. --Select-- (b) Write an equation of change for W. constant dw dt variable (c) Given that the girl weighed 30 pounds at age 3, find a formula for W. W =
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
