Raul converts numbers in base 10 to base 2. Which answer best defends why Raul would need to do this?

Computers and Technology
1 answer:
gtnhenbr [62]2 years ago
7 0

Answer:

C

Explanation:

All the calculation by computer is performed in base 2. Base 2 is also named as binary computation and it is used in all the computer and digital data processing processors.

Some differences between base 2 and base 10 are:

  • Base 2 number system contains 0 and 1 whereas base 10 is from 0 to 9.
  • Digital systems works on 0 and 1 logic i.e on and off logic. So we use digital system easily in binary domain whereas, decimal system has 0-9 levels and they are hard to be catered in digital domain.
  • Base 10 is used in normal calculations for daily use and binary is only confined to digital domain.

When replacing a system board in a laptop, which feature is a must?
Marta_Voda [28]

Answer:

Having the integrated peripherals in the same locations as the old system board

Explanation:

System board is the printed circuit board that is used to connect the peripheral devices. It provides the slots and ports to connect the peripherals devices.

If there is a need to replace the system board of the laptop. You can change the system board. On new system board, all the peripherals that are installed on previous (old) system board should be placed on new system board. As the system requirements are same, only printed circuit board of the system is changed.

The new system board is replica of the previous board so, we can not change peripheral of the system boards.

Every telecommunication setup uses two devices: one device to transmit data and one device to receive data. Which device transmi
alexandr1967 [171]

Answer:

Cell.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.

In the field of telecommunication, all telecommunication setup are designed and developed to make use of two network devices: one device is typically used for the transmission of data while the other device is used to receive data that are sent on the network.

Generally, cell towers are tall poles that are used to transmit frequencies to mobile phones.

Given parameters b and h which stand for the base and the height of an isosceles triangle (i.e., a triangle that has two equal s
schepotkina [342]

Answer:

The area of the triangle is calculated as thus:

Area = 0.5 * b * h

To calculate the perimeter of the triangle, the measurement of the slant height has to be derived;

Let s represent the slant height;

Dividing the triangle into 2 gives a right angled triangle;

The slant height, s is calculated using Pythagoras theorem as thus

s = \sqrt{b^2 + h^2}

The perimeter of the triangle is then calculated as thus;

Perimeter = s + s + b

Perimeter = \sqrt{b^2 + h^2} + \sqrt{b^2 + h^2} +b

Perimeter = 2\sqrt{b^2 + h^2} + b

For the volume of the cone,

when the triangle is spin, the base of the triangle forms the diameter of the cone;

Volume = \frac{1}{3} \pi * r^2 * h

Where r = \frac{1}{2} * diameter

So, r = \frac{1}{2}b

So, Volume = \frac{1}{3} \pi * (\frac{b}{2})^2 * h

Base on the above illustrations, the program is as follows;

#include<iostream>

#include<cmath>

using namespace std;

void CalcArea(double b, double h)

{

//Calculate Area

double Area = 0.5 * b * h;

//Print Area

cout<<"Area = "<<Area<<endl;

}

void CalcPerimeter(double b, double h)

{

//Calculate Perimeter

double Perimeter = 2 * sqrt(pow(h,2)+pow((0.5 * b),2)) + b;

//Print Perimeter

cout<<"Perimeter = "<<Perimeter<<endl;

}

void CalcVolume(double b, double h)

{

//Calculate Volume

double Volume = (1.0/3.0) * (22.0/7.0) * pow((0.5 * b),2) * h;

//Print Volume

cout<<"Volume = "<<Volume<<endl;

}

int main()

{

double b, h;

//Prompt User for input

cout<<"Base: ";

cin>>b;

cout<<"Height: ";

cin>>h;

//Call CalcVolume function

CalcVolume(b,h);

//Call CalcArea function

CalcArea(b,h);

//Call CalcPerimeter function

CalcPerimeter(b,h);

 

return 0;

}
