Answer:

The correct answer is option A. "True".

Explanation:

Key management could either be manual or automated. The automated key distribution approach is more flexible and dynamic than the manual key distribution approach, because it is better at responding to changing requirements in the system. Additionally, the automated key distribution approach is faster and more economic as well as observable and auditable.

simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9​
motikmotik

Answer:

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

Explanation:

The given expression is:

\frac{2m^2+m-15}{m^2-9}

The numerator can be siplified by using factorization and denominator will be simplified using the formula

a^2-b^2 = (a+b)(a-b)

So,

= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

m-3 = 0 => m = 3

Hence,

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

Write a program in c++ to displaypascal’s triangle?
Harman [31]

<u> C++ Program to Print Pascal's Triangle</u>

 #include<iostream> //header file

using namespace std;

//driver function  

int main()

{

   int r;/*declaring r for Number of rows*/

   cout << "Enter the number of rows : ";

   cin >> r;

   cout << endl;

 

   for (int a = 0; a < r; a++)

   {

       int value = 1;

       for (int b = 1; b < (r - a); b++) /*Printing the indentation space*/

       {

           cout << "   ";

       }

       for (int c = 0; c <= a; c++) /*Finding value of binomial coefficient*/

       {

           cout << "      " << value;

           value = value * (a - c) / (c + 1);

       }

       cout << endl << endl;

   }

   cout << endl;

   return 0;

}

                 1

              1      1

           1      2      1

Write only in C, not C++.
yawa3891 [41]

Answer:

#include <iostream>

using namespace std;

int main() {

  int k;

double d;

string s;

cin >> k >> d >> s;

cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }

                                                                   

Explanation:

k is int type variable that stores integer values.

d is double type variable that stores real number.

s is string type variable that stores word.

cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.

cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.

First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.

Then next line \n is used to produce a new line.

So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.

The program along with the output is attached.

To print the last element in the array named ar, you can write :A. System.out.println(ar.length);
timofeeve [1]

Answer:

Option (d) is the correct answer.

Explanation:

An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.

In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--

System.out.println(ar[ar.length-1]);

No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--

  • Option a will prints the size of the array.
  • Option b also gives the error because length is an undeclared variable.
  • Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.
