Answer:

802.11a

Explanation:

802.11a supports bandwidth of 54 Mbps in a regulated frequency spectrum of 5 GHz. 802.11a also referred to as Wi-fi 2. 802.11a is basically costs higher than 802.11b though both were created at the same time. Hence 802.11b is more popular than 802.11a . All of them are developed by IEEE.

timama [110]

Answer:

1.  the set of real numbers between 0.1 and 0.2

2. the set of all negative integers greater than negative 1 trillion

3.  the set of all java and C programs

Explanation:

A set is countable if it is either finite or has the same cardinality as the set of positive integers. The inverse of this set type is uncountable.

The set of real numbers between 0.1 and 0.2, all negative integers greater than negative 1 billion, and a set of java and C programs are all countable sets, so are considered countably infinite.

<h3>What is Virtual reality (VR)?</h3>

Virtual Reality (VR) is known to be a kind of computer created environment that is made up of scenes and objects that seems to be real.

It is a type of reality that makes its  user feel they are inside their surroundings. This environment is said to be seen via device known as a Virtual Reality headset or helmet.

See options below

Which approach would best utilize VR for this purpose?

an animated video that covers compliance training

a 360-degree online tour of the retail store

an application that enables online contract signing

a simulated experience interacting with customers

Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre
Fudgin [204]

Answer:

The c++ program to implement the while loop is given below.

#include <iostream>

using namespace std;

int main() {

  // declaration of integer variables

   int k, n, total;

   // initialization of integer variables

   k=1, n=4, total=0;

//  loop executed till value of k becomes equal to value of n

   while( k <= n ){

       // cube of every integer is added to the variable total

       total = total + ( k * k * k );

       // value of k is incremented to go to the next number

k = k + 1 ;

   }  

   return 0;

}  

Explanation:

The program begins with the declaration of integer variables.  

int k, n, total;

This is followed by initialization of these variables.

k=1, n=4, total=0;

The while loop runs over the variable k which is initialized to 1. The loop runs till value of k reaches the value of integer n.

First, cube of k is computed and added to the variable total.

After first execution of the loop, total is initialized to the cube of 1.

Next, value of variable k is incremented by 1 so that k is initialized to next integer.

After first execution of the loop, k is incremented from 1 to 2.

while( k <= n )

{

total = total + ( k * k * k );

k = k + 1 ;

   }

When the value of k reaches the value of integer n, the cube of n is calculated and added to the variable, total.

When k is incremented, it becomes more than n and hence, loop gets terminated.

As the return type of main is int, the program terminates with the statement shown below.

return 0;

No output is displayed as it is not mentioned in the question.

No user input is taken as it is mentioned that integer variables are already initialized.
