Answer:

a² + 1/a² = 7

Explanation:

a + 1/a = 3 ; obtain the value of a² + 1/a²

Taking a + 1/a = 3

Squaring both sides ;

(a + 1/a)² = 3²

(a + 1/a)(a + 1/a) = a² + a/a + a/a + 1/a² = 3²

(a + 1/a)(a + 1/a) = a² + 1 + 1 + 1/a² = 9

a² + 2 + 1/a² = 9

a² + 1/a² = 9 - 2

a² + 1/a² = 7

Hence,

a² + 1/a² = 7

Write a program that asks the user for three names, then prints the names in reverse order.

sasho [114]

Answer:

The program written in C++ is as follows'

#include<iostream>

using namespace std;

int main()

{

string names[3];

cout<<"Please enter three names: "<<endl;

for (int i = 0; i< 3;i++)

{

cin>>names[i];

}

for (int i = 2; i>= 0;i--)

{

cout<<names[i]<<endl;

}

return 0;

}

Explanation:

This line declares an array for 3 elements

string names[3];

This line prompts user for three names

cout<<"Please enter three names: "<<endl;

This following iteration lets user input the three names

for (int i = 0; i< 3;i++) { cin>>names[i]; }

The following iteration prints the three names in reverse order

for (int i = 2; i>= 0;i--) { cout<<names[i]<<endl; }

garri49 [273]

The term used to describe whereby old and new media are available via the integration of personal computers and high speed satellite based phone or cable links is: media convergence.

<h3>What's a good illustration of media convergence? </h3>

Smartphones, laptops, and ipads are the finest instances of media convergence since they combine several forms of digital media, including radio, cameras, TVs, music, and more, into a single, straightforward gadget.
The blending of formerly separate media platforms and technologies through digitization and computer networking is referred to as media convergence. Another name for this is technical convergence.
Media ownership concentration, sometimes referred to as media consolidation or media convergence, is the process through which a smaller number of people or organisations come to control a larger portion of the mainstream media.
According to recent study, there is a rising amount of consolidation in the media sectors, which are already highly concentrated and controlled by a very limited number of companies.

To learn more about media convergence, refer to the following link:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

Mnenie [13.5K]

Answer:

(1)Minterms complement = XYZ (2) Compliment of Minterms = Σm(0,1, 2 , 4 , 6) (3) (X+Y+Z) (4) Minimized SOP = Z + XY

Manterms = πM

Explanation:

Solution

Recall that:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

(1) Canonical Disjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as minterms

In Minterm we assign 'I' to each uncomplimented variable and '0' to each complemented/complementary variable

For the given question stated we ave the following:

Minterms = XYZ, XYZ, XYZ, XYZ, XYZ.

(2) Canonical Conjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as maxterms.

In Maxterms we assign '0' to each uncomplimented variable and '1' to each complemented/complementary variable

Compliment of Minterms = Σm(0,1, 2 , 4 , 6)

Maxterms = πM

Note: Kindly find an attached copy of the complete solution to this question below.
