One numerical method for calculating the cubic root of a number, 3 squareroot halley's method. the solution process starts by choosing a value x_1 as a first estimate of the solution. using this value, a second, more accurate value x_2 is calculated with, x_2 = x_1(x_1^3 + 2p)/(2x_1^3 + p) which is then used for calculating a third, still more accurate value x_3 and so on. the general equation for calculating the value of x_i + 1 from the value of x_i is x_i + 1 = x_i(x_i^3 + 2p)/(2x_i^3 + p). write a matlab program that calculates the cubic root of a number. in the program use x_1 = p for the first estimate of the solution. then, by using the general equation in a loop, calculate new, more accurate values. stop the looping when the estimated relative error e defined by e = |x_i + 1 - x_i/x_i) is smaller than 0.1. use the program to calculate: (a) 3√ 800 (b) 3√ 59071 (c) 3√ -31.55

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
