given a double variable named x that has been declared and given a value, let's use a binary search technique to assign an estimate of its square root to another double variable, root that has also been declared. let's assume that x's value is greater than 1.0 -- that will simplify things a bit. here's the general idea: since x>1, we know its square root must be between 1 and x itself. so declare two other variables of type double (a and b say) and initialize them to 1 and x respectively. so we know the square root must be between a and b. our strategy is to change a and b and make them closer and closer to each other but alway make sure that the root we're looking for is between them. (such a condition that must always hold is called an invariant.)
Answers
To estimate the square root of a given double variable x using a binary search technique, you can follow these steps:
1. Declare a double variable named root and initialize it to 0. This variable will hold the estimate of the square root.
2. Declare two more double variables, a and b, and initialize them to 1 and x respectively. These variables will define the range in which the square root must lie. Since x is greater than 1.0, the square root must be between 1 and x.
3. Start a loop that will iterate until the desired accuracy is achieved. You can determine the accuracy based on the difference between a and b.
4. Inside the loop, calculate the midpoint between a and b. This can be done by adding a and b together and dividing the sum by 2. Assign this value to the root variable.
5. Calculate the square of the root value obtained in the previous step.
6. Compare the square of the root with the original value x. If the square is close enough to x (within a certain tolerance), you can break out of the loop and consider the root as the estimated square root of x.
7. If the square of the root is less than x, update the value of a to be the root. This is because the actual square root must be greater than the current root value.
8. If the square of the root is greater than x, update the value of b to be the root. This is because the actual square root must be less than the current root value.
9. Repeat the loop until the desired accuracy is achieved. As you update the values of a and b, the range in which the square root lies will get smaller and smaller, providing a more accurate estimate.
10. Finally, after breaking out of the loop, the value of root will hold the estimated square root of x.
Example:
Let's say x is 9.0. Initially, a = 1 and b = 9. The square root of 9 must be between 1 and 9.
- In the first iteration, the root is calculated as (1 + 9) / 2 = 5.0. The square of 5.0 is 25, which is greater than 9. So, we update b to be 5.0.
- In the second iteration, the root is calculated as (1 + 5) / 2 = 3.0. The square of 3.0 is 9, which is equal to 9 (within the tolerance). We break out of the loop and consider 3.0 as the estimated square root of 9.
Please note that the binary search technique used in this example is just an estimation method and may not provide the exact square root value. However, it can give a close approximation with a desired level of accuracy.

It then squares this midpoint value and if the square of the midpoint is less than x we know that the root of x must be bigger than this midpoint: so we assign the midpoint to a (making a bigger and shrinking our a and b interval by half!)-- and we still can be sure that the root is between a and b. Of course if the midpoint's square is greater than x we do the opposite: we assign b the value of midpoint. But when to stop the loop? In this exercise, just stop when the interval between a and b is less than 0.00001 and assign root the midpoint of a and b then. We call this a binary search also because at each stage we cut the interval under consideration in half. Efficient as this method is, old Isaac Newton discovered an algorithm that is even more efficient and that's what the library function sqrt uses.

How does the average function work? what list does it use? how is it traversed using a for loop?
Answers
The average function works by calculating the average of the numbers in a given list. It takes a list as an argument and returns the average value of the numbers in that list.
The list can be any type of iterable object such as a list, tuple, or dictionary, but it must contain numerical values. To calculate the average, the function first adds up all the numbers In the list and then divides the total by the number of values in the list.
Here's an example of how to use the average function:
pythonnumbers = [1, 2, 3, 4, 5]
avg = sum(numbers) / len(numbers)
print("The average is:", avg)
This code will print out the average of the numbers in the list numbers. The sum() function adds up all the numbers in the list, and the len() function returns the number of values in the list.
The average function can be traversed using a for loop by iterating over each value in the list and adding them up. Here's an example:
pythonnumbers = [1, 2, 3, 4, 5]
total = 0 for num in numbers:
total += numavg = total / len(numbers)
print("The average is:", avg)
In this code, we first initialize a variable total to 0, and then we loop through each value in the list numbers. Inside the loop, we add each value to the total variable. Once the loop is finished, we divide total by the length of the list to get the average value. Finally, we print out the average value using the print() function.

do you see any undesirable effects of humans communicating more and more via computer networks rather than in person or over the telephone.? what dont you like and why? what do you like about it?
Answers
As an AI language model, I do not have personal preferences or feelings, but I can provide some insights. There are certainly some undesirable effects of humans communicating more and more via computer networks.
One potential downside is that online communication lacks the nuance and nonverbal cues that we pick up in face-to-face interactions. This can lead to misunderstandings, misinterpretations, and miscommunication. Additionally, relying solely on computer networks can result in a lack of meaningful connection and a feeling of isolation or loneliness.
On the other hand, there are also some benefits to communicating via computer networks. It allows us to connect with people from all over the world in real time, which can foster greater understanding and empathy across cultures. It also makes it easier to maintain relationships with people who live far away or have busy schedules.
Overall, it's important to strike a balance between communicating online and communicating in person or over the phone. Both forms of communication have their own strengths and weaknesses, and it's up to individuals to decide what works best for them in different situations.

C. used artificial intelligence so that the computers become reasonably intelligent all on their own
Third-generation computers were developed in the 1960s and marked a significant advancement in the development of computers. They were the first computers to use integrated circuits, which allowed for smaller and more powerful computers. Third-generation computers also featured the development of high-level programming languages, such as COBOL and FORTRAN, which made it easier for programmers to write and understand code. These computers also used magnetic tape and disks for storage, which were much more efficient than the punched cards used in earlier computers. Third-generation computers made use of artificial intelligence, which allowed them to perform tasks that required some level of independent thought and decision-making.

Answers
Answer:
PAN (Personal Area Network)
Explanation:
A network that typically reaches only a few meters (10 m or 33 ft) and contains personal devices like mobile computers, smartphones and handheld devices is called PAN (Personal Area Network).
PAN enables communication between devices that are near a human being (i.e. only for shorter distances).
It can be wireless such as bluetooth earphones used with the smartphone, wireless keyboard and mouse used with laptop or computer, TV and remote control communication.
It can be wired such as wired earphones used with the smartphone, any USB (Universal Serial Bus) device connected to a computer/laptop.
FILL IN THE BLANK. The surface of a magnetic disk platter is divided into ____.
A) sectors
B) arms
C) tracks
D) cylinders
Answers
The surface of a magnetic disk platter is divided into c) tracks.
Tracks are concentric circles on the disk platter where data is stored. They allow the read/write head of a disk drive to access and store information. Tracks are further divided into smaller units called sectors, which hold a specific amount of data, typically 512 bytes.
Sectors are the smallest addressable unit on the disk, and the combination of multiple tracks and sectors creates a grid-like structure for data storage. The read/write head moves over the tracks while the platter spins, enabling efficient data access and storage.
Other terms you mentioned, like arms and cylinders, are related to magnetic disk platters but not the correct answer for filling in the blank. Arms are the mechanical components that hold the read/write heads and move them across the disk platter to access different tracks. Cylinders, on the other hand, refer to the set of tracks on multiple platters that are aligned vertically. This alignment allows the read/write head to access the same track position across all platters without moving, thus increasing storage capacity and performance.
In summary, the surface of a magnetic disk platter is divided into tracks, which are further divided into sectors for efficient data storage and retrieval.
Therefore, the correct answer is c) tracks

How to build adjacency matrix for undirected/directed graph?
Answers
An adjacency matrix is a 2D array in which each row and column represent a vertex in the graph. The value stored in the matrix indicates whether the two vertices have an edge between them or not. The adjacency matrix for an undirected graph is symmetrical along the diagonal, whereas the adjacency matrix for a directed graph is not.
Both the rows and columns in an adjacency matrix for an undirected graph have the same number of entries. Additionally, when there is an edge from vertex i to vertex j in an undirected graph, the value at A[i,j] and A[j,i] is 1. It is symmetrical about the leading diagonal in this way. Furthermore .
An adjacency matrix for a directed graph, on the other hand, is not symmetrical around the main diagonal. The number of entries in the rows and columns may vary in an adjacency matrix for a directed graph, depending on the number of incoming and outgoing edges for each vertex. If there is an edge from vertex i to vertex j, the value in A[i,j] is 1, but the value in A[j,i] is 0 if there is no edge from j to i. An example of a directed graph's adjacency matrix is given below:
