Answer:
The use case diagram is attached.
Explanation:
Create a set of use cases for the following health club membership system:
When members join the health club, they pay a fee for a certain length of time. Most memberships are for one year, but memberships as short as two months are available. Throughout the year, the health club offers a variety of discounts on its regular membership prices (e.g., two memberships for the price of one for Valentine's Day). It is common for members to pay different amounts for the same length of membership. The club wants to mail out reminder letters to members asking them to renew their memberships one month before their memberships expire. Some members have become angry when asked to renew at a much higher rate than their original membership contract, so that the clubwants to track the price paid so that the manager can override the regular prices with special prices when members are asked to renew. The system must track these new prices so that renewals can be processed accurately. One of the problems in the healthclub industry is the high turnover rate of members. While some members remain active for many years, about half of the members do not renew their memberships. This is a major problem because the health club spends a lot in advertising to attract each new member. The manager wants the system to track each time a member comes into the club. The system will then identify the heavy users and generate a report so that the manager can ask them to renew their memberships early, perhaps offering them a reduced rate for early renewal. Likewise, the system should identify members who have not visited the club in more than a month so that the manager can call them and attempt to reinterest them in the club.

D) To determine which posts from a particular user have received the greatest number of comments
<u>Explanation:</u>
Since social media excepting comments from end user website or social media should keep track of end user information such as name with email address and phone extra.
If we do so we can end user information in cans, end user post, wrong post information can be blocked or given end user information for further analysis. Moreover web site can receive positive or negative posts.
For me all four will be my answer. If we don’t track any information about end user it is against to law.
public class ArithmeticAssignment {
public static void main(String[] args) {
Tester test = new Tester();
test.printTester();
}
}
class Tester{
Tester(){
}
void printTester(){
int i1 = 79 + 3 * (4 + 82 -68) - 7 +19;
int i2 = (179 +21 +10) / 7 + 181;
int i3 = 10389 * 56 * 11 + 2246;
System.out.println(i1);
System.out.println(i2);
System.out.println(i3);
}
}
I think this is what you wanted. I hope this helps!

4. D
5. A
6. B
Explanation:
CPU: this is known as the central processing unit and it is considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.
A. Decode unit: decodes instructions and data and transmits the data to other areas in an understandable format.
B. Register unit: contains many separate, smaller storage units. Modern CPUs need only a few nanoseconds to execute an instruction when all operands are in its registers.
C. Bus unit: it is used to connect all the other major components together, accepts data, and sends data through the input and output bus sections.
D. Control unit: control of the overall operations of the CPU. The component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit how to respond to informations sent to the processor.
E. Arithmetic logic unit (ALU): performs mathematical functions on data stored in the register area.
F. Cache: small temporary memory area that separates and stores income data and instructions.
