A farmer has 2000 feet of fencing available to enclose a rectangular field. One side of the field is a river, so only three sides require fencing. Express the area A as a function of x, where x is the length of the side parallel to the river. a) A = -x²/2 + 2000x b) A = - x²/2 + 1000x c) A = x² - 2000x d) A = x² + 1000x e) A = -x² + 1000x The function w(x) = -0.01x² + 0.27x + 8.60 can be used to estimate the number of self-employed workers in America in millions, x years after 1980. For what years were there (or will be there) 9.7 million self-employed worker in America? Answers _________________ and _______________________
