Answers

Answer 1

To define a function `make_derivative` that returns a function, we can use a nested function definition. The inner function will take a number `a` as an argument and return the approximate derivative of `f` at point `a` using the formula `f'(a) = (f(a+h) - f(a))/h` with a very small value for `h`. The outer function will return the inner function. Here is the code:

```python
def make_derivative(f):
   def derivative(a):
       h = 0.00001
       return (f(a+h) - f(a))/h
   return derivative
```

We can then use this function to create a derivative function for any single-variable mathematical function `f`. For example, if we have a function `square` that returns the square of a number:

```python
def square(x):
   return x*x
```

We can create a derivative function for `square` by calling `make_derivative` with `square` as an argument:

```python
derivative = make_derivative(square)
```

Now we can use `derivative` to approximate the derivative of `square` at any point `a`:

```python
result = derivative(3)
```

And we can round the result to 3 decimal places:

```python
round(result, 3)
```

This will return `6.0`, which is approximately `2*3`.

during tcp/ip communications between two network hosts, information is encapsulated on the sending host and de-encapsulated on the receiving host using the osi model. which information type format occurs at the data link layer of the osi model?

Answers

During TCP/IP communications between two network hosts, the format of the information type that occurs at the data link layer of the OSI model is known as the frame format.

TCP/IP refers to a set of protocols that support network communications. The protocols of the Internet protocol suite are commonly referred to as TCP/IP. It is the standard protocol for communication on the Internet. The OSI model is a reference model that provides an architectural framework for the implementation of network protocols. The OSI model has seven layers. Each layer of the OSI model defines a specific function of the communication process. Each layer of the OSI model encapsulates the data, adds a header, and sends it to the next layer.The format of the information type that occurs at the data link layer of the OSI model is known as the frame format. It consists of a header and a trailer. The header includes the source and destination MAC addresses, protocol type, and optional fields such as VLAN tags. The trailer contains the cyclic redundancy check (CRC) value. The CRC value is used to detect errors in the frame. The data link layer is responsible for providing reliable data transfer over a physical link. It is the second layer of the OSI model. The data link layer is responsible for encapsulating the data received from the network layer into frames, adding a header and a trailer to the frame and transmitting the frame to the physical layer.

to ensure that text is easily read on low resolution devices, we should use a higher x-height. true or false?

Answers

To ensure that text is easily read on low resolution devices, we should use a higher x-height. This statement is true.

What is an x-height?

The distance between the baseline of a line of type and the top of the main body of lower case letters is referred to as x-height. The x-height is a critical aspect of text readability, particularly in body copy. It determines the visual impact of a typeface and its legibility in smaller sizes.

Resolution and higher x-heightResolution has an impact on the visual quality of typefaces. As the resolution gets lower, typefaces become more difficult to read. The x-height is increased to make text more readable on low-resolution devices. When we use a typeface with a higher x-height, the size of lowercase letters is increased. This implies that the height of lowercase letters is closer to the height of uppercase letters.

As a result, lower-case letters appear larger, and the words appear to have more space between them. In conclusion, to ensure that text is easily read on low-resolution devices, we should use a higher x-height.

which of the following metrics do we have for finding dissimilarity between two clusters in hierarchical clustering? 1. single linkage, 2. complete linkage, 3. average linkage

Answers

The metrics for finding dissimilarity between two clusters in hierarchical clustering are single linkage, complete linkage, and average linkage.

What is hierarchical clustering?

Hierarchical clustering is a type of data clustering method that builds a hierarchy of clusters that resemble a tree-like structure or a dendrogram. The methods for building this hierarchy are divided into two types: agglomerative and divisive. In hierarchical clustering, we have several metrics for determining dissimilarity between two clusters. The most commonly used ones are:

Single linkage, also known as the nearest neighbor method, compares the closest points between two clusters. It connects the two closest points from each cluster and forms a new cluster. This approach is a faster method, but it is sensitive to noise and tends to create long chains.

Complete linkage, also known as the farthest neighbor method, compares the farthest points between two clusters. It connects the two farthest points from each cluster and forms a new cluster. This method is less sensitive to noise and tends to produce compact clusters, but it is slower than the single linkage method.

Average linkage calculates the average distance between all pairs of data points in two different clusters. It then connects the two clusters that have the smallest average distance. This method is slower than single linkage but is more robust to noise and outliers.

Answers

The output of executing the code segment will be (D) 5. Here's how the method works: It initializes a count variable to 0 and a curr variable to the last element of the input array.

It then iterates through the array and compares each element to the curr variable. If the element is greater than curr, count is incremented by 1. Otherwise, count is decremented by 1. After each comparison, curr is set to the current element. Finally, the method returns the count value. For the given input array [4, 14, 15, 3, 14, 18, 19], the method will compare each element to the previous one as follows: 4 < 19: count = -1  14 < 4: count = -2  15 > 14: count = -1  3 < 15: count = -2  14 < 3: count = -3  18 > 14: count = -2  19 > 18: count = -1  So the final count value is -1 - 2 - 1 - 2 + 1 - 2 - 1 = -6. However, the question asks for the absolute value of the count, which is 6, and since option B is not present, the correct answer is (D) 5.

what is mechanical advantage of a lever of a grain crusher

Answers

Explanation:

The mechanical advantage of a lever of a grain crusher is the ratio of the output force to the input force. It is a measure of how much easier it is to do a job using the lever compared to doing it without. For example, if the output force is twice as great as the input force, then the mechanical advantage of the lever would be 2. This means that the job can be done with half the effort. The mechanical advantage of a lever of a grain crusher can be increased by increasing the length of the lever arm, which reduces the input force required to move the grain. This makes it easier to crush the grain, as less force is needed to do the job.

To define a function cycle that takes in three functions f1, f2, f3, as arguments and returns another function that takes in an integer argument n and return another function, we can use the following code:

```python
def cycle(f1, f2, f3):
   def inner_func(n):
       def final_func(x):
           # Initialize result to x
           result = x
           # Use a for loop to iterate through n times
           for i in range(n):
               # Apply f1, f2, and f3 in a cycle depending on the value of i
               if i % 3 == 0:
                   result = f1(result)
               elif i % 3 == 1:
                   result = f2(result)
               else:
                   result = f3(result)
           return result
       return final_func
   return inner_func
```

This code defines a function cycle that takes in three functions f1, f2, and f3 as arguments. It then defines an inner function inner_func that takes in an integer argument n. Inside inner_func, we define another function final_func that takes in an argument x. Inside final_func, we use a for loop to iterate through n times and apply f1, f2, and f3 in a cycle depending on the value of i. Finally, we return the result.

What ipv4 address class has the ip address 221. 1. 2. 3?

Answers

The IPv4 address class of 221.1.2.3 is Class C. The IPv4 protocol uses address classes to define the size of the network portion of the address and the number of hosts that can be assigned to it.

The first octet of the IP address determines the address class. Class C addresses have their first three bits set to 110 and the fourth bit set to 0, which allows for 24 bits to be used to define the network portion of the address. This means that Class C networks can support up to 256 (2^8) hosts per network and are commonly used in small to medium-sized businesses.In computer networking, an IPv4 address is a unique identifier assigned to devices on a network using the Internet Protocol version 4. IPv4 addresses are 32-bit binary numbers that are typically represented in human-readable format as a series of four decimal numbers separated by periods. Each of these decimal numbers represents a byte of the binary number, with values ranging from 0 to 255. IPv4 addresses are divided into classes based on the range of values in the first byte, with Class A addresses having a range from 1 to 126, Class B addresses from 128 to 191, and Class C addresses from 192 to 223. The remaining address ranges are reserved for special purposes, such as multicast or private networks.

This would increase the coverage area and distribution of signals, reducing the overcrowding at the existing tower and ensuring that signals are transmitted and received effectively. Adding more wifi routers (b) or ensuring all devices have Bluetooth (a) would not address the issue of overcrowding on the cell tower, as they are not designed to handle mobile signals. Changing the type of waves used to transmit signals (c) may not be practical, as it would require a complete overhaul of the existing network infrastructure and may not necessarily address the issue of overcrowding on the tower.

write a function named abs sum that takes a list of integers as a parameter and returns the sum of the absolute values of each element in the list. for example, the absolute sum of [-1, 2, -4, 6, -9] is 22. if the list is empty, return 0. use python's functional programming constructs, such as list comprehensions, map, filter, reduce, to implement your function. do not use any loops or recursion in your solution.

Answers

To write a function named abs_sum that takes a list of integers as a parameter and returns the sum of the absolute values of each element in the list, we can use Python's functional programming constructs, such as map and reduce. Here is the solution:

```python
from functools import reduce

def abs_sum(lst):
 # Use map to apply the absolute value function to each element in the list
 abs_lst = map(abs, lst)
 # Use reduce to sum the absolute values in the list
 result = reduce(lambda x, y: x + y, abs_lst, 0)
 return result
```

For example, the absolute sum of [-1, 2, -4, 6, -9] is 22:

```python
print(abs_sum([-1, 2, -4, 6, -9])) # 22
```

If the list is empty, the function will return 0:

```python
print(abs_sum([])) # 0
```

This solution does not use any loops or recursion, as required in the question.

The code appears to contain a syntax mistake since the for loop's closing curly brace is missing. The result will be based on the values of the continentNames array, assuming the missing brace is added.

Is it syntax mistake if a bracket is missing?

When programmers apply a preset structure or linguistic pattern incorrectly, syntax errors—also referred to as parse errors—occur in JavaScript. Code that contains typos or other errors is invalid. Common mistakes include missing parenthesis or punctuation.

Given a string and a non-empty substring sub, compute recursively the largest substring which starts and ends with sub and return its length.

strDist("catcowcat", "cat") → 9

strDist("catcowcat", "cow") → 3

strDist("cccatcowcatxx", "cat") → 9

Answers

The given query asks for a recursive function that finds the largest substring in a given string that starts and ends with a specified non-empty substring. One suggested approach is to find the first and last occurrences of the substring, and then calculate the length of the resulting substring.

If the difference between the two indexes is zero or negative, the function should be called again with a shortened string. This can be repeated until a valid result is found . Another solution is to recursively call the function with the substring removed from the beginning and end of the string until the substring is no longer present. The length of the resulting string is then returned .In computer language, a string is a sequence of characters that is used to represent text or other data. A string can include letters, numbers, symbols, and whitespace, and it can have any length.

A substring is a smaller sequence of characters that is contained within a larger string. A substring can be any length, but it must be a contiguous sequence of characters that occurs within the larger string.

In programming, there are many tasks that involve manipulating strings and substrings. For example, you might need to search for a particular substring within a larger string, extract a specific substring from a larger string, or replace one substring with another.

There are many built-in functions and libraries in programming languages that provide tools for working with strings and substrings, such as the substring method in JavaScript, the string module in Python, or the String class in Java.

you will be designing an algorithm and developing a c program for the problem described below: have the user input three test grades and then display the tests in increasing order, followed by the average. for example: enter score 1: 88.8 enter score 1: 50 enter score 1: 100 the average of 50, 88.8 and 100 is: 79.6 (note: follow the steps below in creating your algorithm and c program)

Answers

Algorithm to design and developing the program is:

1. Ask the user to input three test grades2. Store the grades in three separate variables3. Compare the first two test grades, and if the first grade is larger, swap the two4. Compare the second and third test grades, and if the second grade is larger, swap the two5. Calculate the average of the three test grades6. Display the grades in increasing order, followed by the average


C Program:

#include

int main()

{

   //Variable declarations

   float grade1, grade2, grade3;

   float avg;


   //User prompt to input grades

   printf("Enter score 1: ");

   scanf("%f", &grade1);


   printf("Enter score 2: ");

   scanf("%f", &grade2);


   printf("Enter score 3: ");

   scanf("%f", &grade3);


   //Swap grades if needed

   if (grade1 > grade2) {

       float temp = grade1;

       grade1 = grade2;

       grade2 = temp;

   }


   if (grade2 > grade3) {

       float temp = grade2;

       grade2 = grade3;

       grade3 = temp;

   }


   //Calculate average

   avg = (grade1 + grade2 + grade3)/3;


   //Display output

Difference between c++ and java?

Answers

Answer:

C++ is platform-dependent.

]Java is platform-independent.

C++ is mainly used for system programming.

Java is mainly used for application programming. It is widely used in Windows-based, web-based, enterprise, and mobile applications.

C++ uses compiler only. C++ is compiled and run using the compiler which converts source code into machine code so, C++ is platform dependent.

Java uses both compiler and interpreter. Java source code is converted into bytecode at compilation time. The interpreter executes this bytecode at runtime and produces output. Java is interpreted that is why it is platform-independent.

C++ is an object-oriented language. However, in the C language, a single root hierarchy is not possible.

Java is also an object-oriented language. However, everything (except fundamental types) is an object in Java. It is a single root hierarchy as everything gets derived from java.lang.Object.
