The correction is C.
One of the major factors that determine the quality of a printer is the resolution of that printer. The resolution is also called DPI [Dots Per Inch]. The DPI refers to amount of ink that an inkjet printer can place in a one inch line of a printed document. The higher the DPI of a printer, the higher the resolution.

HELP ASAP, AND YES I KNOW, WRONG CATEGORY. SORRY!

Anastasy [175]

Answer:

A. ensemble.

Explanation:

A musical ensemble can be defined as a group of people who play instrumental and vocal music. It is also known as a music group and carries a distinct name. The word ensemble is derived from the Middle French ensemblée, meaning together at the same time.

A rock band will come under the category of a musical ensemble as it is also a group of people performing instrumental music or vocal music.

Therefore, option A is correct.

The class attribute a. can be applied to only one element in an HTML document b. determines the copy that will be displayed when

Nuetrik [128]

Answer:

The answer is likely C. "Can be used by CSS to apply the same formatting to more than one HTML element."

Explanation:

Given that the name of the attribute is "class," it sounds like the kind of code that would be applied to multiple elements intended to display something a specific way.

Qualification:

I've invested hours of my time into learning HTML, but I've never dealt with the "class" attribute. So, maybe take my answer as a grain of salt.

What two devices in a computer should be considered "black boxes," and should never be opened due to risks involving charged cap

NNADVOKAT [17]

The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.

Explanation:

Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.

Integers and booleans. Write a program RightTriangle that takes three int command-line arguments and determines whether they con

icang [17]

Answer:

The programming language is not stated;

I'll answer using C++

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int side1, side2, side3;

cout<<"Enter the three sides of the triangle: "<<endl;

cin>>side1>>side2>>side3;

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

else {

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

else {

cout<<"Not Right Angled";

}

return 0;

}

Explanation:

The following line declares the three variables

int side1, side2, side3;

The next line prompts user for input of the three sides

cout<<"Enter the three sides of the triangle: "<<endl;

The next line gets user input

cin>>side1>>side2>>side3;

The following if condition checks if any of user input is negative or 0

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

If otherwise

else {

The following if condition assumes that side1 is the largest and test using Pythagoras Theorem

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side2 is the largest and test using Pythagoras Theorem

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side3 is the largest and test using Pythagoras Theorem

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

If none of the above conditions is true, then the triangle is not a right angles triangle

else {

cout<<"Not Right Angled";

}

}

return 0;
