Find the steady-state temperature $u(r, \theta)$ within a hollow sphere $a < r < b$ if its inner surface $r = a$ is kept at temperature $f(\theta)$ and its outer surface $r = b$ is kept at temperature zero. The sphere in the first octant is shown in the figure below. (Let $P_n$ denote the $n^{th}$ Legendre polynomial.) $u(r, \theta) = \sum_{n=0}^{\infty} \left[ \Box \right] \left( \int_0^{\pi} f(\theta) P_n(\cos \theta) \sin \theta \, d\theta \right) P_n(\cos \theta)$

Part 2. Given two filenames and a word to be searched as commandline arguments, open the first file to read and the second for writing. Write each line of the first file that contains the search word as a substring to the second file. Part 3. Write a program that reads lines of text from a text file. Each line of the input file contains a telephone number as in the form 555-555-5555. Use fgets and strtok functions to extract the area code (first 3 digits of this string) as a token, the first three digits of the phone number as a token, and the last four digits as a token. Create a single string containing the phone number as in format (555) 555 5555 and output it to a file called \"out-part2.txt\".

Required 1. Estimate the regression equation for (a) medical supplies costs and number of procedures and (b) medical supplies costs and number of patient-hours. You should obtain the following results: Regression 1: Medical supplies costs = $a + ($b \times Number of procedures) Variable Coefficient Standard Error $t$-Value Constant $36,939.77 $56,404.86 0.65 Independent variable: No. of procedures $ 361.91 $ 152.93 2.37 $r^2$ = 0.36; Durbin-Watson statistic = 2.48 Regression 2: Medical supplies costs = $a + ($b \times Number of patient-hours) Variable Coefficient Standard Error $t$-Value Constant $3,654.86 $23,569.51 0.16 Independent variable: No. of patient-hours $ 56.76 $ 7.82 7.25 $r^2$ = 0.84; Durbin-Watson statistic = 1.91 2. On different graphs plot the data and the regression lines for each of the following cost functions: a. Medical supplies costs = $a + ($b \times Number of procedures) b. Medical supplies costs = $a + ($b \times Number of patient-hours) 3. Evaluate the regression models for \"Number of procedures\" and \"Number of patient-hours\" as the cost driver according to the format of Exhibit 10-18 (page 406). 4. Based on your analysis, which cost driver should Julie Chen adopt for Apollo Hospital? Explain your answer.
