Answer:
A mid shot or medium shot
Explanation:
import java.util.Scanner;
public class polygon {
/** Main Method */
public static void main(String[] args) {
Scanner input = new Scanner(System.in); // Create a Scanner
// Prompt the user to enter the number of sides
// and the side of a regular polygon
System.out.print("Enter the number of sides: ");
int n = input.nextInt();
System.out.print("Enter the side: ");
double side = input.nextDouble();
// Display the area of the regular polygon
System.out.println("The area of the polygon is " + area(n, side));
}
/** Method area computes and returns the area of a regular polygon */
public static double area(int n, double side) {
return (n * Math.pow(side, 2) / (4 * Math.tan(Math.PI / n)));
}
}
Answer:
Directive
Explanation:
A directive access control is used to direct, confine, or control the actions of subject to force compliance with security policies. Some examples of direct access controls are: security guards, guard dogs, posted notifications, monitoring, supervising, work task procedures, and awareness training. It can also be categorized by how it is implemented; for example, it can be administrative, logical/technical, or physical.
<span>In general you want to use the cheapest storage medium who's speed is compatible with the function it needs to perform. For active storage that's handled while running programs, you need memory whose speed is closely matched to the processor speed. And that would be the rather expensive semiconductor memory which is close to ideal for the task. But semiconductor memory has the disadvantage of being expensive and it loses the values stored when power is lost. So slower, persistent storage is used such as SSD (Solid State Drives) and hard disks. That media is cheaper, but slower, but still fast enough to handle tasks such as loading programs and data into memory for execution, or storing data generated by programs to persistent storage. But as with all man made things, disasters happen. Computers break down, hard disks crash, floods and fires happen, etc., and as a result data is lost. So we make backups. Backups have to have a lot of storage and they have to be cheap. But they don't need rapid access, you can start at the beginning and read (or write) all the way to the end. And for that purpose, magnetic tape is ideal. Magnetic tape is actually quite fast when you're simply streaming a continuous stream of data without any need to randomly access any piece of that data. And it's cheap, so you're willing to make a back up copy of your system and store that backup off site so a single disaster won't destroy both the primary system and the backup.</span>
