Answer:
x = (-b + sqr(b * b - 4 * a * c)) / (2 * a)
x2 = (-b - sqr(b * b - 4 * a * c)) / (2 * a)
Usually when squaring a number I just use multiply it by itself like above. If you actually want to use the exponent 2, then it would instead be:
x = (-b + sqr(b ^ 2 - 4 * a * c)) / (2 * a)
x2 = (-b - sqr(b ^ 2 - 4 * a * c)) / (2 * a)
The answer is A. Decreasing
Answer:
Yes, if you want to be undetected.
Explanation:
It is vital to always use a command that will ensure that one's activity is undetected. This is one of the important rules of corporate organizations to keep their data and activities safe and secure. The commend provided is a useful tool for detective works especially the activities of criminals and hackers. Therefore, if the admin wants to be undetected, the command should not be used.
Answer:
Follows are the code to this question:
#include <iostream>//defining a header file
using namespace std;
int roll()//defining a method roll
{
return 1+(rand() %5);//use return keyword that uses a rand method
}
int main()//defining main method
{
cout<<roll();//calling roll method that print is value
return 0;
}
Output:
4
Explanation:
In this code, the "roll" method is defined, that uses the rand method with the return keyword, that returns the value between 1 to 6, and in the next step, the main method is declared, that uses the print method to calls the roll method.
