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

What are the modes of operation of WLANs?

Nimfa-mama [501]

Answer:

WLAN's or Wireless LAN Units have 2 main modes of operation

Explanation:

The Two Main modes of Operation are the following

Infrastructure Mode: in this mode the main WLAN unit becomes the main connection point in which all devices are connected to and the main unit provides an internet connection to all the devices connected to it.

Ad Hoc Mode: in this mode devices transfer data from one another back and forth without permission from a base unit.

Some WLAN units will also include 2 extra modes of operation called Bridge and Wireless Distribution System (WDS).

Bridge Mode: this mode allows the base unit to act as an intermediary and bridge two different connection points. Such as bridging a wired connection with a wireless one.

WDS Mode: this mode uses various access points to wirelessly interconnect devices to the internet using repeaters to transmit connections. It can provide internet to both wired and wireless clients.

Assume that a gallon of paint covers about 350 square feet of wall space. Create an application with a main() method that prompt

Makovka662 [10]

Answer:

C++

#include <iostream>

#include <cmath>

using namespace std;

///////////////////////////////////////////////////////////////////////

int noOfGallons(int wallArea) {

int gallon = 350;

int gallon_price = 32.0;

float total_price = 0.0;

///////////////////////////////////////////

float noOfGallons = (float)wallArea/(float)gallon;

printf("No of gallons needed %.2f", noOfGallons);

cout<<endl;

//////////////////////////////////////////

total_price = noOfGallons*gallon_price;

return round(total_price);

}

int wallArea(int length, int width, int height) {

int wall_area = length*width;

int total_price = noOfGallons(wall_area);

}

///////////////////////////////////////////////////////////////////////

int main() {

int length, width, height;

///////////////////////////////////////////
