The weight, W, in lbs, of a child is a function of its age, a, in years, so W = f(a). (a) Do you expect f ′(a) to be positive or negative? Why? (b) What does f(8) = 45 tell you? Give units for the numbers 8 and 45. (c) What are the units of f ′(a)? Explain what f ′(a) tells you in terms of age and weight. (d) What does f ′(8) = 4 tell you about age and weight? (e) As a increases, do you expect f ′(a) to increase or decrease? Explain.

a) positive

b) the child is 45 lbs when she's 8 years old

c) lbs/year

d) The child increases 4 lbs/year when she's 8 years old

e) decrease

Step-by-step explanation:

a) Positive for the child because as they grow (age increases), a normal child should gain weight.

b) It tells that when age (years) = 8, the child weights 45 lbs

c) The unit of f' would be lbs/year. As it's a derivative of f (lbs) with respect to time t (years)

d) f'(8) = 4 tells us that the child weights increase at the rate of 4 lbs/year when she's 8 years old

e) As a increases f'(a) would decreases, as the rate of weight gain of a child would be slowing down as she grows.

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
