Helen [10]

Answer:

Explanation:

The following code is written in Java. It creates the Card class and then uses it to create a full house and print out the rank and suit of every card in that hand.

class Card {

   int rank;

   char suit;

   public Card(int rank, char suit) {

       this.rank = rank;

       this.suit = suit;

   }

   public int getRank() {

       return rank;

   }

   public char getSuit() {

       return suit;

   }

}

class CardTester {

   public static void main(String[] args) {

       Card card1 = new Card(3, '♥');

       Card card2 = new Card(3, '♠');

       Card card3 = new Card(3, '♦');

       Card card4 = new Card(2, '♦');

       Card card5 = new Card(2, '♣');

       System.out.println("Card 1: " + card1.getRank() + " of " + card1.getSuit());

       System.out.println("Card 2: " + card2.getRank() + " of " + card2.getSuit());

       System.out.println("Card 3: " + card3.getRank() + " of " + card3.getSuit());

       System.out.println("Card 4: " + card4.getRank() + " of " + card4.getSuit());

       System.out.println("Card 5: " + card5.getRank() + " of " + card5.getSuit());

   }

Router 1 is configured with static NAT. Addressing on the router and the web server are correctly configured, but there is no co
marin [14]

Answer:

The router NAT configuration has an incorrect inside local address.

Explanation:

The term Inside in a <em>Network Address Translation (NAT) </em>context refers to networks owned by an organisation that must be translated. When NAT is configured, hosts within this network have addresses in one space (known as the local address space). These hosts appear to those users outside the network as being in another space (known as the global address space).

The term Outside refers to those networks to which the stub network connects, and which are not under the control of an organisation. Also, hosts in outside networks can be subject to translation, and can thus have local and global addresses

Write a program to draw a text-based graph of a mathematical function f(x)
Makovka662 [10]
I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math import math def main(): function = input("Enter a function f(x):\n") x = 0 y = 0 for rows in range(10,-11,-1): for col in range(-10,11,1): x=col roundfx = round(eval(function)) if roundfx == rows: print("o", end="") if rows==0 and col==0 and not rows == roundfx: print("+", end="") if col == 0 and not rows == 0 and not rows == roundfx: print("|", end="") if rows==0 and not col==0 and not rows == roundfx: print("-", end="") else: if not rows == 0: if not col == 0: if not rows == roundfx: print(" ", end="") print() main()
