Solve the problem.Let y(t) be the population of a species of plant that is being harvested, for t ? 0. Consider the harvesting model 
where h is the annual harvesting rate, y0 is the initial population of the species, and t is measured in years. If y0 = 5000, what harvesting rate should be used to maintain a constant population of y = 5000, for t ? 0?
A. h = 5000 yr-1 B. h = 10 yr-1 C. h = 100 yr-1 D. h = 25 yr-1

Solve the problem.A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 14 inches by 20 inches by cutting out equal squares of side x at each corner and then folding up the sides as in the figure. Express the volume V of the box as a function of x.
A. V(x) = x(14 - x)(20 - x) B. V(x) = x(14 - 2x)(20 - 2x) C. V(x) = (14 - x)(20 - x) D. V(x) = (14 - 2x)(20 - 2x)
