Answer:

DHCP server

Explanation:

The first option that we must check is the DHCP server (The Dynamic Host Configuration Protocol) server because this is the protocol that gives us the IP addresses to connect with the internet if we don't have an IP (Internet Protocol) address, we can never have an internet connection, if the DNS fails we cannot connect with the internet, but regularly the DHCP is the main issue if there are not physical issues.

Solution is c language please help me.

nordsb [41]

Explanation:

in c++

#include<iostream.h>

#using namespace std;

main()

{ float x,y,z,r, phi, theta;

cout<<" enter the value of x";

cin>>x;

cout<<" enter the value of y";

cin>>y;

cout<<" enter the value of z";

cin>>z;

r = (sqrt(pow(x,2) + pow(y, 2) + pow(z, 2)));

phi = (asinf(y/r)*180.0f)/PI;

theta = (asinf(-x/(r*cosf(phi)))*180.0f)/PI;

cout<<"The radius r= "<<r;

cout<<"The phi angle= "<<phi;

cout<<"The theta angle= "<<theta;

return 0;

Consider the following relation: CAR_SALE (Car#, Date_sold, Salesman#, Commision%, Discount_amt Assume that a car may be sold by

Nady [450]

Answer:

See explaination

Explanation:

The given relation is:

CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)

Primary key: {Car#,Salesperson#}

We will first check whether the relation is in 1NF.

A relation is said to be in the 1st Normal form(1NF) if all the columns in the relation have atomic values. In this case, the relation is in 1NF.

A relation is said to be in the second normal form(2NF) if it satisfies the condition that all non keys are completely dependent on the primary key and just a part of the primary key.

In the case of the CAR_SALE relation, the Commission% depends only on the Salesperson# and not on the combination of Car# and Salesperson#. This means that the given relation is not in 2NF. To satisfy 2NF, we make two relationships as given below:

SALE_DETAIL(Salesperson#, Commission%)

and CAR_SALE(Car#, Date_sold, Salesperson#, Discount_amt)

Now both the relations are in 2NF.

For a relation to be in 3NF, no non-key should be functionally dependent on another non key.

In the case of the CAR_SALE relation, it is specified that the Date_sold field determines the Discount_amt. Therefore the modified CAR_SALE is not in 3NF.

To satisfy 3NF, we seperate the non key and the dependent non key and create a different table.

Final Relations:

SALE_DETAIL(Salesperson#, Commission%)

Discount_Detail(Date_Sold, Discount_Amt)

CAR_SALE(Car#, Date_sold, Salesperson#)

What is the name of the item that supplies the exact or near exact voltage at the required wattage to all of the circuitry insid

Karo-lina-s [1.5K]

Answer:

A voltage regulator.

Explanation:

A voltage regulator, controls the output of an alternating current or a direct current (depending on the design), allowing the exact amount of voltage or wattage to be supplied to the computer hardware. This device sometimes uses a simple feed-forward design or may include negative feedback. The two major types of voltage regulator are based on either the electromechanical or electronic components.

The electronic types were based on the arrangement of resistor in series with a diode or series of diodes, and the electromechanical types are based on coiling the sensing wire to make an electromagnet.

The constructor signature is defined as the constructor __________ followed by the __________.

d1i1m1o1n [39]

Answer:

The constructor signature is defined as the constructor name followed by the parameter list.

Explanation:

In object oriented programming, a class constructor is a special method that will run automatically whenever a new object is created from the class. The constructor name is same with the class name. Besides, the class constructor is often used to initialize the attributes with initial values. Those initial values are held by the parameter list of the constructor.

One example of the constructor defined in a Java class is as follows:

// class name

public class BankAccount {

// attribute names

private String holder;

private double amount;

// constructor name

public BankAccount(String holder, double amount) // parameter list

{

this.holder = holder;

this.amount = amount

}
