In numerical methods, one source of error occurs when we use an approximation for a mathematical expression that would otherwise be too costly to compute in terms of run-time or memory resources. One routine example is the approximation of infinite series by a finite series that mostly captures the important behavior of the infinite series.
In this problem you will implement an approximation to the exp(x) as represented by the following infinite series,
exp(x) = Infinity n= 0 xn/xn!
Your approximation will be a truncated finite series with N + 1 terms,
exp(x, N) = Infinityn n = 0 xn/xn!
For the first part of this problem, you are given a random real number x and will investigate how well a finite series expansion for exp(x) approximates the infinite series.
Compute exp(x) using a finite series approximation with N E [0, 9] N (i.e. is an integer).
Save the 10 floating point values from your approximation in a numpy array named exp_approx. exp_approx should be of shape (10,) and should be ordered with increasing N (i.e. the first entry of exp_approx should correspond to exp(x, N) when N = 0 and the last entry when N = 9).

       mylist.append([num])

   exp_approx = np.asarray(mylist)

   sum = 0

   for num in exp_approx:

       sum+=num

   return sum

Explanation:

The imports the python math module

The function begins here

def exp(x):

This creates an empty list

   mylist = []

This iterates from 0 to 9

   for n in range(10):

This calculates each term of the series

       num = (x**n)/(math.factorial(n))

This appends the term to list, mylist

       mylist.append([num])

This appends all elements of mylist to numpy array, exp_approx

   exp_approx = np.asarray(mylist)

This initializes the sum of the series to 0

   sum = 0

This iterates through exp_approx

This returns the calculated sum

Currency is a form of payment for goods and services. In a nutshell, it is money in the form of paper and coins that is usually issued by a government and is generally accepted as a form of payment at face value.

Currency exchange rates differ between businesses because each one distorts the interbank rate to maximize profits. We encounter numerous competitors who post interbank rates internet as bait to attract new customers, but once the customers are onboard, they drastically change the rate, typically not in the customers' favor.

Therefore, the $ symbol represents the dollar in a spreadsheet. The US dollar is the country's currency.

Write a test program that prompts the user to enter the number of the items and weight for each item and the weight capacity of the bag, and displays the maximum total weight of the items that can be placed in the bag. Here is a sample run:

Answers

Answer:

The program in Python is as follows:

n = int(input("Number of weights: "))

weights= []

for i in range(n):

   inp = float(input("Weight: "))

   weights.append(inp)

capacity = float(input("Capacity: "))

possible_weights = []

for i in range(n):

   for j in range(i,n):

       if capacity >= weights[i] + weights[j]:

           possible_weights.append(weights[i] + weights[j])

print("Maximum capacity is: ",max(possible_weights))

Explanation:

This gets the number of weights from the user

n = int(input("Number of weights: "))

This initializes the weights (as a list)

weights= []

This iteration gets all weights from the user

for i in range(n):

   inp = float(input("Weight: "))

   weights.append(inp)

This gets the weight capacity

capacity = float(input("Capacity: "))

This initializes the possible weights capacity (as a list)

possible_weights = []

This iterates through the weights list

for i in range(n):

   for j in range(i,n):

This gets all possible weights that can be carried by the bag

       if capacity >= weights[i] + weights[j]:

           possible_weights.append(weights[i] + weights[j])

This prints the maximum of all possible weights

print("Maximum capacity is: ",max(possible_weights))

b. this wouldn't through.

d. it through volta.
e. volts through it.

Answers

Answer:

e. volts through it

Explanation:

volts through it

The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.

What is standard output?

When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).

A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.

The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.

Davos has been reading about encryption recently. He begins to wonder how anything can be secure if everyone is using the same set of algorithms. After all, anyone using the same algorithm would be able to decrypt anything that had been encrypted using that algorithm. Which of the following helps make the data unusable by anyone else using that same encryption scheme without having this information?
a. Algorithm
b. Cipher
c. Key
d. Block

Answers

Answer:

The correct answer is B. Cipher.

Explanation:

Cipher is a system of reversible transformations that depends on some secret parameter, called key, and is designed to ensure the secrecy of transmitted information.

The cipher can be a combination of conventional characters or an algorithm for converting ordinary numbers and letters. The process of making a message secret with a cipher is called encryption. An important parameter of any cipher is the key - a parameter of the cryptographic algorithm, which ensures the selection of one transformation from the set of transformations possible for this algorithm. In modern cryptography, it is assumed that all the secrecy of a cryptographic algorithm is concentrated in the key.

The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.
