____________ reference is used when you want to use the same calculation across multiple rows or columns.
Answer:
relative cell
Explanation:
So, if you want to repeat the same calculation across several columns or rows, you need to use relative cell references. For example, to multiply numbers in column A by 5, you enter this formula in B2: =A2*5. When copied from row 2 to row 3, the formula will change to =A3
Answer:
Relative
Explanation:
Relative reference is used when you want to use the same calculation across multiple rows or columns.

Answer:
LAN,MAN,WANExplanation:
are the three types of networkBinary is a base-2 number system instead of the decimal (base-10) system we are familiar with. Write a recursive function PrintInBinary(int num) that prints the binary representation for a given integer. For example, calling PrintInBinary(5) would print 101. Your function may assume the integer parameter is non-negative. The recursive insight for this problem is to realize you can identify the least significant binary digit by using the modulus operator with value 2. For example, given the integer 35, mod by 2 tells you that the last binary digit must be 1 (i.e. this number is odd), and division by 2 gives you the remaining portion of the integer (17). What 's the right way to handle the remaining portion
Answer:
In C++:
int PrintInBinary(int num){
if (num == 0)
return 0;
else
return (num % 2 + 10 * PrintInBinary(num / 2));
}
Explanation:
This defines the PrintInBinary function
int PrintInBinary(int num){
This returns 0 is num is 0 or num has been reduced to 0
if (num == 0)
return 0;
If otherwise, see below for further explanation
else
return (num % 2 + 10 * PrintInBinary(num / 2));
}
----------------------------------------------------------------------------------------
num % 2 + 10 * PrintInBinary(num / 2)
The above can be split into:
num % 2 and + 10 * PrintInBinary(num / 2)
Assume num is 35.
num % 2 = 1
10 * PrintInBinary(num / 2) => 10 * PrintInBinary(17)
17 will be passed to the function (recursively).
This process will continue until num is 0

3. Given the following total revenue functions, find the corresponding demand functions:
a) TR = 50Q-4Q²
b) TR = 10
a)TR=50Q4Q2 I hope.this helps
A) The demand function for the total revenue function TR = 50Q - 4Q² is;
P = 50 - 4Q
B) The demand function for the total revenue function TR = 10 is; 10/Q
We are given total revenue functions as;
TR = 50Q - 4Q²
TR = 10
A) TR = 50Q - 4Q²
Formula for revenue function if Q represents the units demanded is;
TR = P × Q
Where P is the demand function
Thus;
50Q - 4Q² = PQ
Divide both sides by Q to get the demand function;
P = 50 - 4Q
B) TR = 10
Formula for revenue function if Q represents the units demanded is;
TR = P × Q
Where P is the demand function
Thus;
10 = P × Q
Divide both sides by Q to get the demand function;
P = 10/Q

Explanation historical development of computer
Answer:
Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.
Explanation:
Computers and electronics play an enormous role in today's society, impacting everything from communication and medicine to science.
Although computers are typically viewed as a modern invention involving electronics, computing predates the use of electrical devices. The ancient abacus was perhaps the first digital computing device. Analog computing dates back several millennia as primitive computing devices were used as early as the ancient Greeks and Romans, the most known complex of which being the Antikythera mechanism. Later devices such as the castle clock (1206), slide rule (c. 1624) and Babbage's Difference Engine (1822) are other examples of early mechanical analog computers.
The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching came to be based on this technology, which led to the development of machines that we would recognize as early computers.
The presentation of the Edison Effect in 1885 provided the theoretical background for electronic devices. Originally in the form of vacuum tubes, electronic components were rapidly integrated into electric devices, revolutionizing radio and later television. It was in computers however, where the full impact of electronics was felt. Analog computers used to calculate ballistics were crucial to the outcome of World War II, and the Colossus and the ENIAC, the two earliest electronic digital computers, were developed during the war.
With the invention of solid-state electronics, the transistor and ultimately the integrated circuit, computers would become much smaller and eventually affordable for the average consumer. Today “computers” are present in nearly every aspect of everyday life, from watches to automobiles.
The history of computers is one that began far back 2000 years ago in the city of Babylonia where there was the use of abacus and it has grown to now the use of digital computer as it start in 1642.
What is the history of computer?The history of computers is one that is more than 200 years but in the 19th century, there was the invention of mechanical calculating machines.
Note that the The 1st generation of computers was said to have existed from the year 1940 to 1955 and now it has grown to a whole new level.

Here is the problem specification: An Internet service provider has three different subscription packages for its customers: Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Package C: For $19.95 per month unlimited access is provided. Write a program that calculates a customer's monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B or C. Also, the number of hours used in a month cannot exceed 744. Use switch.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int hour; char pkg; float bill = 0;
cout<<"Package: "; cin>>pkg;
cout<<"Hour: "; cin>>hour;
if(hour<=744 && hour >=0){
switch (pkg) {
case 'A':
bill = hour * 9.95;

break;
default:
cout << "Package must be A, B or C";}
cout<<"Total Bills: $"<<bill; }
else{ cout<<"Hour must be 0 - 744"; }

Explanation:
This declares all variables: int hour; char pkg; float bill=0;
This prompts the user for package type: cout<<"Package: "; cin>>pkg;
This prompts the user for number of hours: cout<<"Hour: "; cin>>hour;
This checks if hour is between 0 and 744 (inclusive)
if(hour<=744 && hour >=0){
If true, the following is executed
A switch statement to check valid input for package
switch (pkg) {
For 'A' package

Explanation:
You should write the client so that it sends 10 ping requests to the server, separated by approximately one second. Each message contains a payload of data that includes the keyword PING, a sequence number, and a timestamp. After sending each packet, the client waits up to one second to receive a reply. If one second goes by without a reply from the server, then the client assumes that its packet or the server's reply packet has been lost in the network.Hint: Cut and paste PingServer, rename the code PingClient, and then modify the code. The two programs follow very similar process.You should write the client so that it starts with the following command:java PingClient host portwhere host is the name of the computer the server is running on and port is the port number it is listening to. Note that you can run the client and server either on different machines or on the same machine.The client should send 10 pings to the server. Because UDP is an unreliable protocol, some of the packets sent to the server may be lost, or some of the packets sent from server to client may be lost. For this reason, the client cannot wait indefinitely for a reply to a ping message. You should have the client wait up to one second for a reply; if no reply is received, then the client should assume that the packet was lost during transmission across the network. You will need to research the API for DatagramSocket to find out how to set the timeout value on a datagram socket.When developing your code, you should run the ping server on your machine, and test your client by sending packets to localhost (or, 127.0.0.1). After you have fully debugged your code, you should see how your application communicates across the network with a ping server run by another member of the class.Message FormatThe ping messages in this lab are formatted in a simple way. Each message contains a sequence of characters terminated by a carriage return character (r) and a line feed character (n). The message contains the following string:PING sequence_number time CRLFwhere sequence_number starts at 0 and progresses to 9 for each successive ping message sent by the client, time is the time when the client sent the message, and CRLF represent the carriage return and line feed characters that terminate the line.
