1. You have a budget of $4800 for constructing a rectangular enclosure that consists of a high fence around the outside and a shorter fence dividing the enclosure into two halves. The high fence costs $12 per foot, and the short fence costs $7 per foot. Find the dimensions of each half of the enclosure that will maximize their areas. Round all of your answers to 2 decimal places. Length= ft ? Width = ft? Maximum area of each region = ft2? Total amount of high fence used = ft ? Total amount of short fence used = ft ? 2. From past records, an orchard owner in the foothills has determined that if 20 apple trees per acre are planted, each tree yields 441 apples on average. The yield decreases by 19 apples per tree for each additional tree planted per acre. How many trees should be planted per acre to achieve the maximum total yield? ? trees should be planted per acre to achieve the maximum yield of ? apples per acre
