The program in Java is as follows:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
float a, b, c, x, y;
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
y = a * x * x + b * x + c;
System.out.print(y); }}
Explanation:
This declares all variables
float a, b, c, x, y;
The next 4 lines get input for a, b, c and x
<em> a = input.nextFloat();</em>
<em> b = input.nextFloat();</em>
<em> c = input.nextFloat();</em>
<em> x = input.nextFloat();</em>
This calculates the value of y using 
This prints the calculated value of y
System.out.print(y);
Answer:
Both types of attacks can be devastating.
Explanation:
Attacks Wireless Networks are sometimes considered more serious because they can be attacked from remote locations. One of the more serious attacks would be against commercial airplanes. A wireless hack and system shutdown of a commercial aircraft can be catastrophic, and can all be done wireless.
