Answer:

System of linear equations is solved below and explained in detail.

Explanation:

Part a:

M = [1  3  5  2; 2  -4  7  -3; 0  -4  -7  3; 5  -3  2  1];

c =  [7;  -3;  -1;  0];

Part b:

The statement used for the solution of system of linear equation will be:

X = linsolve(M,c)

where X will give the values of x1, x2, x3, x4 respectively.

Part c:

The system is solved in matlab using above equation and the results are attached in a file.

The values for X are:

x1 = -2/7

x2 = 3/7

x3 = 4/7

x4 = 11/7

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (
Luden [163]

Answer:

The program in Python is as follows

def Paths(row,col):

if row ==0 or col==0:

 return 1

return (Paths(row-1, col) + Paths(row, col-1))

row = int(input("Row: "))

col = int(input("Column: "))

print("Paths: ", Paths(row,col))

Explanation:

This defines the function

def Paths(row,col):

If row or column is 0, the function returns 1

<em> if row ==0 or col==0: </em>

<em>  return 1 </em>

This calls the function recursively, as long as row and col are greater than 1

<em> return (Paths(row-1, col) + Paths(row, col-1))</em>

The main begins here

This prompts the user for rows

row = int(input("Row: "))

This prompts the user for columns

col = int(input("Column: "))

This calls the Paths function and prints the number of paths

print("Paths: ", Paths(row,col))

Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that
zalisa [80]

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

   int[] array = new int[10];

   int index = 0;

   while(index < array.size()){

           int number = (rand() % 100) + 1;

           for (int i = 0; i < 1; i++) {

               array[index] = number;

               cout<< "Position "<< index << "of the array = "<< number << endl;

               ++index;

           }

     }

}

Explanation:

The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
