Answers

Answer 1

Using the knowledge of computational language in python it is possible to describe a method that combines the stability of the bisection method with the fast convergence of newton’s method.

Writting the code:

def findzero(a, b, tol, maxit, f, df):

# Input:

# a, b = The endpoints of the interval

# tol = The required tolerance

# maxit = Maximum number of iterations

# f, df = The function and its dericative

# Output:

# star = approximation of root

# niter = number of iterations for convergence

# ierr =

# 0, the method converged

# 1, df was singular

# 2, maximum number of iterations has been reached

# Approximating the root

xi_1 = x0 = approximation_of_x0(a, b, f, 100)

# xi_1 is xi-1

for i in range(1, maxit + 1):

# Check if df is singular i.e df(xi_1) is equal to 0

if df(xi_1) == 0:

xstar = xi_1

ierr = 1

niter = i

break

# Calculate next x using Newton Method xi-1 i.e xi_1

xi = Newton_method(xi_1, f, df)

# Check if xi is in [a, b]

if xi >= a and xi <= b:

xi = (a + b)/2

# Check for Convergence

if abs(xi - xi_1) <= tol:

niter = i

xstar = xi

if i == maxit:

ierr = 2

else :

ierr = 0

break

# Check the third condition

if f(a)*f(xi) <= 0:

b = xi

else :

a = xi

# Check if maxiterations are completed

if i == maxit:

xstar = xi

ierr = 2

niter = i

# break

xi_1 = xi

return xstar, niter, ierr

def Newton_method(xi_1, f, df):

xi = xi_1 - (f(xi_1)/ df(xi_1))

return xi

def approximation_of_x0(a, b, f, iterations):

# Using bisection method to approximate the intial root

# if you want to approximate with more accuracy just increase the number of iterations

for i in range(iterations):

xi = (a + b)/2

if f(a)*f(xi) <= 0:

b = xi

else :

a = xi

x0 = (a + b)/2

return x0

# To check the code. i have tested on the sample function

# f = x^2 - 4 i.e 2 is the root of f

# df = 2*x

def f(x):

return (x**2) - 4

Answers

Output-memory DBMS is the new categories of dbms that leads to changes in processing requirements for future is systems.

Software programs called database management systems (DBMS) are used to store, retrieve, and query data. Users can add, read, edit, and delete data from databases using a database management system (DBMS), which acts as an interface between an end-user and the database. DBMSs control the data, the database engine, and the database structure, enabling users and other applications to extract or modify the data. It also contributes to concurrency, uniform data management practices, and data security. The normalization technique, used in database schema design, allows DBMS to optimize the arrangement of data by dividing large tables into smaller ones when any of their properties have redundant values. In comparison to conventional file systems, DBMS are more flexible and have a more sophisticated backup system.

use a loop invariant to prove that the following algorithm converts the positive binary integer, which is stored in the array b, to decimal. for example, the binary integer 10011, which is 19 in decimal, is stored as b[1]

Answers

A condition [among program variables] that is unavoidably true just before and just after each iteration of a loop is known as a loop invariant.

Key details that describe why code functions are captured by loop invariants. This means that you should add a comment that specifies the loop invariant whenever you create code in which the invariant is not immediately apparent. This makes the code easier to comprehend for other programmers and helps prevent future modifications from inadvertently breaking the invariant. When seen as an assertion that specifies significant relationships among the variables that must be true at the beginning of each iteration and when the loop closes, a loop invariant can aid in the design of iterative algorithms.

What did the settlers hope to gain? 1 So your mom made both you and your brother take piano lessons. After just a few months, your brother is playing really hard pieces of music. You, on the other hand, cant seem to get out of the beginner music book. You decide that your brother just has musical talent and you dont, and that no matter how hard you practice, youll never be as good as he is. But is that really true? Or are you just looking for an excuse to stop playing the piano?2 This is an argument that musicians and scientists love to revisit: Is musical ability an innate talent, or is it just the result of practice and determination? When someone is very good at a given thing, what is it that actually makes him good? asks Dr. K. Anders Ericsson, a psychology professor at Florida State University. Ericsson led a group of researchers in one of the most important studies about talent versus practice. Ericsson believes that two people can have the same ability to do something, such as play the piano, but the one who can engage in something called deliberate practice will be the one who becomes the most proficient.3 Deliberate practice isnt just logging in so many hours of practice time, but involves setting specific goals of skills the person needs to work on, getting immediate feedback, and concentrating on technique. Ericsson and his colleagues published a 900-page book called the Cambridge Handbook of Expertise and Expert Performance, in which they say that talent is overrated. They write that expert performers are made through practice and hard work, not simply born with amazing talent. They also suggest that if people pursue something that they love, they are more likely to work hard at it and be successful. Many people avoid doing things that they dont think theyre good at. They give up and tell themselves that they just dont have the talent. Instead, what they really dont have is the desire to be really good and the dedication to regularly practice to reach their goal.4 A lot of people believe there are some inherent limits they were born with, Ericsson says. But there is surprisingly little hard evidence that anyone could attain any kind of exceptional performance without spending a lot of time perfecting it.5 In his 2008 book Outliers, author Malcolm Gladwell summed up Ericssons work and repeatedly stated that anyone could become proficient and successful in his or her fieldincluding musicif they practiced for 10,000 hours, which he called the 10,000 Hour Rule. He writes that practice isnt the thing you do once youre good, but rather, the thing you do that makes you good. Even for those people who seem to have talent to start with, this amount of practice can make the difference between being average and being elite.6 Many scientists are questioning the entire idea of talent, calling it a myth. Folk psychologythe beliefs that people have about human behavior, usually handed down over generations as well as coming from individual experienceteaches us that talents are present at birth and only certain people are born with these special abilities. But scientists have studied successful musicians and found that many of them did not show any particular signs of talent at a very early age. Those who did were usually a part of a household where a parent was musical or encouraged musical activities. A child might show interest in music, and the parent then provides the musical training that helps the child become a good musician.8 Some psychologists believe that, while practice is extremely important, there is a component of intellectual ability that helps determine whether someone will be good at something like playing the piano. According to a study by psychologists David Hambrick and Elizabeth Meinz in the journal Current Directions in Psychological Science, working memory capacity, which is a core part of overall intellectual ability, can predict success in something like playing an instrument. They measured the sight-reading ability of pianists, which is the ability to successfully play a piece of music that they have never seen before. They studied two pianists who had accumulated the same number of practice hours, but had different levels of working memory capacity. The pianist with the higher working memory capacity performed better on the sight-reading task.Part A What is the best definition of the phrase working memory capacity as it is used in paragraph 8?the power of the brain to process informationthe ability of the brain to focus on a task or ideasthe length of time a useful piece of memory laststhe ability to commit ideas or routines to memory could you give me 5 chemistry equations and an explanation of them solved chemistry equations please I REALLY NEED HELP WITH THIS!!Determine the angles of a rotation A) 90 clockwise B) 90 counterclockwise C) 180 D) 270 clockwise E) 270 counterclockwise is 2 correct answers Archimedes drained the water in his tub.The amount of water left in the tub (in liters) as a function of time (in minutes) is graphed.How fast did the water drain?Choose one answer:A. 72 liters per minuteB. 74 liters per minuteC. 76 liters per minuteD. 78 liters per minute If a population consists of mainly older individuals, how would you expect the future population size to respond? find the measure of each angle.
