This is using python.
Assuming all the variables are non-zero.
Which lines of code will assign the discriminant the value b2−4ac? Select 2 options.
discriminant = bb - 4ac
discriminant = b * b - 4 * a * c
discriminant = b ^ 2 - 4ac
discriminant = b ** 2 - 4 * a * c
discriminant = b ^ 2 - 4 * a * c
Answer:
discriminant = b * b - 4 * a * c
discriminant = b ** 2 - 4 * a * c
Explanation:
The operands are correct and in the right order (for python).
** is the operand for squaring something.
* is the operand for multiplying something.
- is the operand for subtracting something.
Let's take a look at these examples individually.
discriminant = bb - 4ac. You have to use the * sign so the computer understands that you're trying to multiply two objects together.
discriminant = b * b - 4 * a * c. This example works because it's using the * where it's appropriate.
discriminant = b ^ 2 - 4ac. In python we don't use the ^ sign. To use exponents, we use **. Also, there is no * sign in between 4, a, and c.
discriminant = b ** 2 - 4 * a * c. This example works because it uses the ** and * sign where appropriate.
discriminant = b ^ 2 - 4 * a * c. This example uses the ^ sign and python does not support it.

What are the four main components of programming languages, and why is each one needed?
Answer:
The four main components of programming languages are variables, control structures, data structures, and syntax.
Explanation:
The four main components of programming languages are variables, control structures, data structures, and syntax. The variables are used to store information that can be stored and manipulated in a computer program. They provide a way of labeling data with a descriptive name, so our programs can be understood more clearly. Control structures are the building blocks of computers programs. They are commands that enable a program to “take decisions.” Data structures is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values. Syntax of a computer language is the set of rules that defines the combinations of symbols that are considered to be correctly structured statements or expressions in that language. Syntax therefore refers to the form of the code.

When an object is acted on by unbalanced forces, the object will always
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.

Your manager has requested you keep a timesheet showing how many hours you work each day and what projects you work on during that time. Using spreadsheet software, how can you total your hours at the end of each week to provide a quick and accurate amount? Use the MIN and MAX functions. Use the AVERAGE function. Use the SUM function.
A: Use the MIN and MAX functions.
B: Use the AVERAGE function.
C: Use the SUM function.
Answer:
I had to use Microsoft Excel for a while when I was working as a dispatcher, inputting pricing and hours and such. C Would be the correct answer.
Explanation:
Average function would just average out the entire week. Though, if the entire week was 8 hours a day, the average would indeed be 8 hours. But it is not the correct answer if one assumes it's not steady like that. Min and Max, depending how it is setup will find the minimum number, and or the maximum number. Making that incorrect as well.

Lionel is a director working on a children's video. He's finding it difficult to manage so many young actors. What should Lionel do to free himself for other creative work?
Answer:
Explanation:
There are two things that Lionel can do in order to free himself. One of which would be to create a program that automates the management process of the young actors, such as scheduling them, payments, rehearsals, etc. Anything that Lionel would have to spend time on to do that does not require face to face communication can be automated, thus saving him time. The second thing that Lionel can do is to limit his workday with the children, therefore leaving more time in the day to pursue other creative work.

it is necessary to separate page numbers with a _____ when printing multiple pages of a document
A. Comma
B. Space
C. Period
Answer:
A. Comma
Explanation:
In computer technology, a printer is an electronic output device (peripheral) that is used for the printing of paper documents (texts and images).
Generally, the standard text procedure for printing is to use sans-serif fonts for headlines and serif fonts for body text. This ultimately implies that, for any printed work such as novels, books, newspapers etc, it is a general rule for a printer to use sans-serif fonts for headlines and serif fonts for body text in order to enhance readability.
Also, it can be reversed in some instances by using a serif font for headlines and a sans-serif font for the body of a text.
Sometimes, when printing a document, an end user may wish to print multiple pages at a goal without any break. In order to achieve this, the user should enter the number of the pages while separating them with a comma in the print dialog box such as 1, 3, 15, 20.
Hence, it is necessary to separate page numbers with a comma when printing multiple pages of a document.
Additionally, you should use a comma for a non-sequential page (1, 3, 7, 15) and a dash for a sequential page (1-9) when printing multiple pages of a document.
MacBook Pro (2019) at 93% max capacity battery rating after 100 charge cycles. Is this normal? Used coconut battery to check this.
Answer:
This is not a normal situation. Go to Apple Support!!!
1,000 battery cycles
Most current Macs (MacBooks, MacBook Airs, and MacBook Pros) use batteries assessed as having 1,000 battery cycles. That's pretty much good enough for at least three years of regular use.
Your battery might drain fast when you're working on your Mac because, for one reason or another, you're running one-too-many apps at the same time. ... To do this, simply click on the battery icon on the top right corner of your screen, or run the activity monitor app.
Use this website for more ways to fix your computer:
https://pdf.wondershare.com/macos-10-14/fix-battery-issue-on-macos-10-14.html
I say it depends if you got the computer at the beginning of the year. If you got it later in 2019, go to the apple store and ask.

Why are Sequences, Selection, and Iteration building blocks of algorithms?
Answer:
An algorithm is a step by step process that describes how to solve a problem in a way that always gives a correct answer.
An algorithm is made up of three basic building blocks: sequencing, selection, and iteration.
Sequencing: An algorithm is a step-by-step process, and the order of those steps are crucial to ensuring the correctness of an algorithm.
Selection: Algorithms can use selection to determine a different set of steps to execute based on a Boolean expression.
Iteration: Algorithms often use repetition to execute steps a certain number of times or until a certain condition is met.

A local bank has just one branch. It sets up a peer-to-peer network for all devices on the system. The bank would like to be able to have one technician administer the entire network from his location outside the bank without having to go to the bank each time there is a problem. Will this be possible for the technician?
Answer: C. It will not work because it needs to use a server in a central location to allow for the remote access they want.
Explanation:
The options are:
A. It will not work because it is not possible to have the technician administer from one single location.
B. It will work as long as a LAN network is established to facilitate the communication between devices.
C. It will not work because it needs to use a server in a central location to allow for the remote access they want.
D. It will work if it uses a WAN network to bring in all of the LAN networks to one central location.
A peer-to-peer network occurs when computer's are connected together and hence share resources are connected and share resources.
In the scenario in the question, the technician cannot administer the entire network from his location outside the bank. The technician will need to go to the bank whenever a problem occurs. This is due to the fact that there I need for a server that is in a central location in order to allow for the remote access they want.
Answer:
It will not work because it needs to use a server in a central location to allow for the remote access they want.

Which operating system function has a steeper learning curve and can potentially break the system without careful use of its operations?
1. Graphical user interface (GUI)
2. Service management
3. Application management
4. Command line interface (CLI)
Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI).
