2) [5 points) A rectangular field adjacent to a river is to be enclosed. Fencing along the river costs $5 per meter, and the fencing for the other sides costs S3 per meter. The area of the field is to be 1200 m. Find the dimensions of the field that is the least expensive to enclose. You must solve all the equations using MATLAB, no credits will be given otherwise.

CU . a) A farmer wishes to enclose a rectangular pen whose area is 168 ft?.On 3 of the sides, he can use regular Fencing, which costs S3/ft. On the remaining side, he must use heavy-duty fencing, which costs S4/ft. Find the dimensions and cost of the most economical fence? ocus b) An open box with a square base must a have a volume of 864 in3. Find the least amount (area) of thin cardboard needed...
Consider the following problem: A breeder of horses wants to fence three rectangular grazing fields along the river with 1800 total feet of fencing as shown below. (Let x denote the vertical length of each of two sides and two dividers. Let y denote the horizontal length for each of the three grazing areas.) What is the largest possible total area (for all three grazing fields together) that she can enclose? What would the dimensions be for each grazing field?...
1. (12 points) Find all the critical points of f(x) = (x - 1)(x + 5) Hint: Do not expand! Instead use the product and chain rules then factor 2. (12 points) Find the absolute extrema of f(x) = on (-1,2). Give your answers as (x,y) points. Hint: It is much easier to take the derivative of f(x) by rewriting as f(x) = (1 + x4)-1 and use the chain rule 3. f(x) = ? - 7x + 1 (a)...
