b = int(input("Enter the coefficients of b: "))
c = int(input("Enter the coefficients of c: "))
d = b**2-4*a*c # discriminant
if d < 0:
print ("This equation has no real solution")
elif d == 0:
x = (-b+math.sqrt(b**2-4*a*c))/2*a
print ("This equation has one solutions: "), x
else:
x1 = (-b+math.sqrt((b**2)-(4*(a*c))))/(2*a)
x2 = (-b-math.sqrt((b**2)-(4*(a*c))))/(2*a)
print ("This equation has two solutions: ", x1, " or", x2)

Write a program that requests the user input a word, then prints every other letter of the word starting with the first letter.
Hint - you will need to use the substring method inside a loop to get at every other character in the String. You can use the length method on the String
to work out when this loop should end.
Sample run:
Input a word:
domain
dmi
import java.util.Scanner;
public class JavaApplication42 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Input a word:");
String word = scan.nextLine();
for (int i = 0; i < word.length(); i+=2){
System.out.print(word.substring(i,i+1));
}
}
}

The program is an illustration of loops.
Loops are used to carry out repetition operations; examples are the for-loop and the while-loop.
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
public class Main {
public static void main(String args[]) {
//This creates a Scanner object
Scanner input = new Scanner(System.in);
//This prompts user for input
System.out.print("Input a word: ");
//This gets input from the user
String userinput = input.nextLine();
//The following iterates through every other character of userinput
for(int i =0;i<userinput.length();i+=2) {
//This prints every other characters
System.out.print(userinput.charAt(i));
}
}
}
The above program is implemented using a for loop

A group of friends goes on a holiday to the mountains. The image form that is best for uploading photos is PNG. The correct option is B.
What is the PNG format of the image?To display high-quality digital images, websites frequently use the PNG file format. PNGs, which were developed to outperform GIF files, provide not just lossless compression but also a significantly wider and brighter color spectrum.
Raster image files come in both JPEG and PNG varieties. This indicates that they are composed of a set number of color pixels.

explain how the organ systems work together to warm up the body on a cold day
Answer:
Your body is to cold ,blood vessels in the skin contract , and blood flow to the extremities (arms and legs)slows . muscles contract and relax rapidly which generates heat to keep you warm..
Explanation:
Hope this helps :)
Answer:
Sample Response: The brain, through the nervous system, sends signals to the muscular system, causing the muscles to move rapidly. This rapid motion produces heat in the body and is observed as shivering. The brain also sends signals to the muscles right beneath the skin. These muscles shorten and tighten, causing the hairs on the skin to stand up. When the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm.

(Java) Write a program that accepts a number of minutes and converts it both to hours and days. For example, 6000 minutes is 100.0 hours or 4.166666666666667 days.
The program is a sequential program, and it does not require any conditional statement or iteration.
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
//This declares minutes as a double data type
double mins;
//This creates a Scanner object
Scanner input = new Scanner(System.in);
//This gets input for minutes
mins = input.nextDouble();
//This converts the minutes to hour and days, and also print them
System.out.println(mins/60+" hours or "+mins/1440+" days");
}
}
At the end of the program, the equivalent number of hours and number of days are printed.

Where do high tides occur? (Select two.)
WILL GIVE BRANLEST PLS ASAP
only at the South Pole
on the side of Earth opposite the moon
on the side of the Earth facing the moon
only at the North Pole
at both the North and South Poles
Answer: The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. High tide (left) and low tide (right) in the Bay of Fundy in Canada.
Explanation:
So the two I think will be 1. On the side of the earth facing the moon and I think both south and North Pole

What will be displayed in the console when the following program runs?
var count = 0
while (count != 5){
console.log(count);
count = count + 2;
}
Answer:
The integer, count, will be stuck in a infinite while loop, and the console will keep adding 2 to count, so it'll look something like this.
0
2
4
6
8
10
12
14
and so forth...
Explanation:
The while loop will never stop because count can not equal to 5 because you can't add 2 to another multiple of 2 to get 5.
Because count cannot reach 5, and you cannot add 2 to another multiple of 2, the while loop will never come to an end.
What displayed in the console when program runs?An endless loop is a section of code that never reaches the ending condition, hence it keeps running indefinitely. An infinite loop may cause your software or browser to crash or freeze. Infinite loops must be understood in order to avoid such situations.
When a condition always evaluates to true, an infinite loop happens. Typically, this is a mistake. You may, for instance, have a loop that decreases until it hits zero.
Therefore, It will resemble this because the integer count will be locked in an unending while loop and the console will keep adding 2 to count. 0, 2,4, 6, 8, 10,12, 14 The program will end in an infinite loop.

Ryo currently earns a monthly salary of $2200. She has been offered a raise of $250 per month. How much more will she earn per year at her new salary?
Answer:
$3,000 more per year
Explanation:
Since the difference between her old salary and her new salary is $250 per month, then we can simply multiply this amount by the 12 months in a year in order to calculate how much more she will be earning per year on her new salary...
$250 * 12 = $3,000
Therefore, we can see that Ryo will be earning an extra $3,000 more per year with her new raise when compared to her old salary.
Keith has data in row 12. However, he would actually like that row to be empty. Keith should _____. A.) double-click on cell A12 and press Backspace B.) highlight row 12 and press Delete C.) use the arrow keys to move to row 12 and press Enter or Return D.) use the mouse to click row 12 and press the space bar
Answer:
B.)
Explanation:
In order to have that row, empty Keith should highlight row 12 and press Delete. This would delete all of the data in the row without effectively deleting the formulas. Therefore, allowing you to easily reuse the row if you need to add data to it once again. So this would be the best option for Keith as it easily solves the problem that he is having.
