1. For each of the following question, the symbols represent the usual meaning. Here, N = 156 Do not round off any digits from the solution. Solve the problems for the following equation. Also calculate true percent relative error and approximate percent relative error: f(x) = -2x3 – 11.7x? – 17.7x + 20 a. Suppose you want to find the root of this equation using bisection method. In one iteration, x, = -15, xu = N. Find out the estimated root after 3 iteration. b. Suppose you want to find the root of this equation using Newton-Raphson method. In the ith iteration, the estimate, x; = N. Find out the estimated root after 3 iteration.

The resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?

You are a business analyst who develop solutions to some farm business problems. One of the difficulties in maintaining a farm is the existence of harmful pests. You were able to find out that the cost P in pesos of removing x amount (in percent) of pests is given by the equation P = 500 000x/ (1 - x). Make a business presentation that includes the following: %3D a. Cost in removing 25%, 50%, and 75% of pests b. Amount of pests removed with the following conditions: • Cost will be no more than P750 000 Cost will be P2 000 000 or less Cost will not go beyond P4 500 000 Make sure that your report is clear, concise, complete, and accurate. The farm owner will use your report for further study and recommendation.
