A farmer has 100 acres on which to plant two crops. The cost of planting the first crop is $20 per acre and the second crop is $40 per acre, and up to $3000 is available to cover the cost of planting. Each acre of the first crop will require 5 work-hours for harvesting and each acre of the second crop will require 20 work-hours. The farmer can rely on having only a total of 1350 work-hours for harvesting the two crops. If the profit is $100 per acre for the first crop and $300 per acre for the second crop, determine the acreage that should be planted with each crop in order to maximize the total profit.

Prove (a) cosh2(x) ā sinh2(x) = 1 and (b) 1 ā tanh 2(x) = sech 2(x). solution (a) cosh2(x) ā sinh2(x) = ex + eāx 2 2 ā 2 = e2x + 2 + eā2x 4 ā = 4 = . (b) we start with the identity proved in part (a): cosh2(x) ā sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 ā sinh2(x) cosh2(x) = 1 or 1 ā tanh 2(x) = .
