express in Qbasic assignment statement
[tex]v = \ \sqrt{t} ^{2} - 4s \div {d}^{4} [/tex]

[tex]K = {8}{x} ^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4} [/tex]

Answers

Answer:

v = sqr(t^(1/2)) - 4 * s / d^4

K = 8 * x^3 - 2 * y^6 / 5 * d + e^4

Explanation:

Given

[tex]v = \ \sqrt{t} ^{2} - 4s \div {d}^{4}[/tex]

[tex]K = {8}{x}^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4}[/tex]

Required

The equivalent in Q Basic

To solve this, we use the following rules:

+ , - and * are written as + , - and *

[tex]\div[/tex] is written as /

^ stands for raise to power

SQR is used for square

^(1/2) stands for square root.

So, the equivalents of the above statements are:

v = SQR(t^(1/2)) - 4 * s / d^4

K = 8 * x^3 - 2 * y^6 / 5 * d + e^4

Which of the following are true statements about the Java wrapper classes (Select all that apply.): Select one or more: a. Objects of these type are immutable b. Objects of these types are mutable c. The wrapper classes do not have no-arg constructors d. The wrapper classes do have no-arg constructors

Answers

Answer:

a. Objects of these type are immutable.

Explanation:

Java wrapper classes are used to convert data into objects. The primitive data is not object and it does not belong to any class. Therefore Java wrapper classes help the user to convert primitive data into object. These objects are immutable and they have no arg constructor.

Project files are maintained in a central repository.

It allows many developers to work on the same project from anywhere at the same time.

The process may require file locking, depending on file type.

Answers

Answer:

Explanation:

Distributed Version Control Systems are a must for any development team. Some of the characteristics of these systems include

Project files are maintained in a central repository.

It allows many developers to work on the same project from anywhere at the same time.

A full copy of all project files is stored on each developer’s computer.

It is somewhat similar to a Centralized Version Control system, with the main difference being that every team developer has a complete project copy in their own system. This allows them to work on the project without access to the internet. Instead, they make changes and update their own server version. This updated version later gets pushed to the centralized server.

Answer:

1. It allows many developers to work on the same project from anywhere at the same time.

2. Project files are maintained in a central repository.

3. A full copy of all project files is stored on each developer’s computer.

It is the way to convey a message,an idea,a picture,or speech that is received and understood clearly and correctly by the person for whom it is sent.​

Answers

Answer:

Communication.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.

In this context, communication is the way to convey a message, an idea, a picture, or speech that is received and understood clearly and correctly by the person for whom it is sent.​

Generally, the linear model of communication comprises of four (4) main components and these are;

1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.

2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.

3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.

4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.

You make a purchase at a local hardware store, but what you've bought is too big to take home in your car. For a small fee, you arrange to have the hardware store deliver your purchase for you. You pay for your purchase, plus the sales taxes, plus the fee. The taxes are 7.5% and the fee is $20. (i) Write a function t(x) for the total, after taxes, on the purchase amount x. Write another function f(x) for the total, including the delivery fee, on the purchase amount x. (ii) Calculate and interpret (f o t)(x) and (t o f )(x). Which results in a lower cost to you

Answers

Answer:

[tex]f(x) = 1.075x[/tex]

[tex]t(x) = x + 20[/tex]

[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]

[tex](t\ o\ f)(x) = 1.075x + 20[/tex]

Explanation:

Given

[tex]Tax = 7.5\%[/tex]

[tex]Fee = \$20[/tex] -- delivery

Solving (a): The function for total cost, after tax.

This is calculated as:

[tex]f(x) = Tax *(1 + x)[/tex]

Where:

[tex]x \to[/tex] total purchase

So, we have:

[tex]f(x) = x * (1 + 7.5\%)[/tex]

[tex]f(x) = x * (1 + 0.075)[/tex]

[tex]f(x) = x * 1.075[/tex]

[tex]f(x) = 1.075x[/tex]

Solving (b): Include the delivery fee

[tex]t(x) = x + Fee[/tex]

[tex]t(x) = x + 20[/tex]

Solving (c): (f o t)(x) and (t o f)(x)

[tex](f\ o\ t)(x) = f(t(x))[/tex]

We have:

[tex]f(x) = 1.075x[/tex]

So:

[tex]f(t(x)) = 1.075t(x)[/tex]

This gives:

[tex]f(t(x)) = 1.075*(x + 20)[/tex]

Expand

[tex]f(t(x)) = 1.075x + 21.5[/tex]

So:

[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]

[tex](t\ o\ f)(x) = t(f(x))[/tex]

We have:

[tex]t(x) = x + 20[/tex]

So:

[tex]t(f(x)) = f(x) + 20[/tex]

This gives:

[tex]t(f(x)) = 1.075x + 20[/tex]

We have:

[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex] ---- This represents the function to pay tax on the item and on the delivery

[tex](t\ o\ f)(x) = 1.075x + 20[/tex] --- This represents the function to pay tax on the item only

The x coefficients in both equations are equal.

So, we compare the constants

[tex]20 < 21.5[/tex] means that (t o f)(x) has a lower cost

Lori Redford, who has been a member of the Project Management group, was recently promoted to manager of the team. She has been added as a member of the Managers group. Several days after being promoted, Lori needs to have performance reviews with the team she manages but she cannot access the performance management system. As a member of the Managers group, she should have the Allow permission to access this system. What is most likely preventing her from accessing this system

Answers

Answer:

she is still a member of the Project Management group

Explanation:

The most likely reason for this is that she is still a member of the Project Management group. This would prevent her from accessing the performance management system. The performance management system most likely allows access to the Managers Group but denies access to the Project Management Group. Therefore, since the deny access overrides the allow access, it would ultimately cause Lori to be unable to access the system. In order to fix this, she would simply need to leave the Project Management Group.
