Newton-Raphson In contrast to the fixed-point method in Exercises 2.4, we found the method in Exercises 2.3 to converge very quickly. There we used the iteration function $g(x) = \frac{R + x^2}{2x}$ (a) Verify that $\sqrt{R}$ is a fixed point of $g(x)$ for all $R \neq 0$. (b) Use the graphs $y = x$ and $y = g(x)$ for each value of R to track the iterates $x_1, x_2, ...$ explain the rapid convergence. (c) Evaluate $g'(\sqrt{R})$ and explain how this impacts convergence of the Newton-Raphson method.

Consider an expensive part with a reliability of 97.4%. If the part fails, it will cost the firm $9,000. a. What is the expected failure cost per part? The probability of failure is % (round your response to two decimal places). The expected failure cost per part is $ (round your response to the nearest penny). b. On each part, a rather unreliable backup can be installed that has a reliability of just 35.00%. What is the maximum amount that the firm should be willing to pay per part to install the backup? The new probability of failure is % (round your response to two decimal places). The new expected cost of failure is $ (round your response to the nearest penny). The firm should pay as much as $ for the backup (round your response to the nearest penny). c. Suppose that a second 35.00% reliable backup part could be installed, so that if both the original and the first backup part fail, then the second backup part will be used. If that second backup part costs $120.00, should it be installed? Support your answer. The new probability of failure is % (round your response to two decimal places). The new expected cost of failure is $ (round your response to the nearest penny). The firm should pay as much as $ for the backup (round your response to the nearest penny). Should the firm install the second backup? Yes No
