A method named addRow that takes two parameters: the first is a two-dimensional array of doubles, and the second is a one-dimensional array of doubles. The method must return a new two-dimensional array of doubles that results from adding the second parameter (one-dimensional array) as a last row to the first parameter (two-dimensional array). The following implementation forms the new array by making it point to the same rows of the 2-dimensional array and the 1-dimensional array: public static double[][] addRow(double [] array, double[]row)[ double[][] newArray = new double[array.length+1][]: for(int i=0; i"A Worn Path" by Eudora Welty write what you think are the most memorable events that occur on Phoenix’s journey to the doctor.

- 8.7 LAB: Volume of a rectangular box - lw/sw Given the dimensions of a rectangular box, write a program to calculate the volume of the box and store the result at memory address 4024. Assume the dimensions are stored in the following memory locations: Ex: If the dimensions are initialized in the simulator as: the result is stored at memory address 4024: Addresses Variables 4000 Length Width 4008 4016 Addresses Data 5 4000 4008 Height 4016 4 3 Addresses Data14.3 There exists processor with 16-bit word length (8-bit addressing unit) with a memory size of 32k words. The addressing method is register - based and direct. Instructions are encoded in two types: single-word and two-word with 3 addresses. Assuming there are no more than 576 -25- different instructions, what is the maximum possible number of general purpose registers in this processor? Note: In single-word instructions all three operands are registersFirst class was posted in this question, third class will be posted in a different question, please refer to it, thank you: https://www.bartleby.com/questions-and-answers/computer-science-question/34b2a175-1365-4989-a811-33c7e8b66a7b Do not change the function names or given starter code in the script. Each class has different requirements, read them carefully. Do not use the exec or eval functions, nor are you allowed to use regular expressions (re module). All methods that output a string must return the string, not print it. If you are unable to complete a method, use the pass statement to avoid syntax errors. Section 2: The Calculator class Implement a class that calculates mathematic expressions. The input passed to this Calculator is in infix notation, which gets converted to postfix internally, then the postfix expression is evaluated (we evaluate in postfix instead of infix because of how much simpler it is). More details about infix to postfix conversion can be found…
