Which of the following is an advantage of using functions? (Select the best answer.) (medals.1) Functions make a program longer and more complex. Functions can be imported and then used by many programs. Functions reduce the number of programmers working on a project. Functions can automatically fix errors in a program's code.
computer because computer is technology and pencil is not and spoon.
I can't tell you the number of times I've had to use BIOS to fix something on my machine

For this question, I'm not sure if you have multiple choice answers; if you do and my answer doesn't really fit into any of them, let me know and we'll take it from there.
Putting anything on the internet can pretty much guarantee that it will stay on the internet forever. Someone, whether it be someone who saved/screenshot your post or the service that controls the posts of the website saving a copy of it and all other posts, it's impossible to get rid of all remnants of a post once you have posted it. Think of all the people who may have reblogged/retweeted/re-whatevered a post on a service that supports it, too.
Most social networks put in their Terms and Conditions that they are allowed to see any and all of what anyone posts or sends to someone through their service. If you DM your significant other a picture of you that you wouldn't want your mom to see, the social service then has the right to view and save information related to the post for quality/functionality/ whatever other reasons. Social services usually have the right to save copies of any information you give to them, whether it be your name/email address or a credit card, for advertising/other purposes.
Also keep in mind that caches exist. The entire purpose of Google Cache is to dig up HTML's from old websites that don't exist anymore for the purposes of allowing someone to view their beauty once more.
Point is, you can burn papers and the information that they held, as long as it wasn't copies and distributed, will be gone. But it's not exactly possible to burn deep-rooted information in the internet's servers that may not be accessible to you once you have deleted your copy of it, but very much accessible to anyone with the expertise to dig it out.
Hope this helped you out! Feel free to ask any additional questions if you have any. :-)
A security system uses sensors at every door and window which will set off an alarm if any one of them is opened. There is also a keypad by an entry door to turn on or turn off the system. Describe how these components can be wired in a combination circuit to provide the needed security.
I wouldn't say this is true. As an artist, colour theory has to do with colour combination and mixing and helps artists see which colours look good together, what they should mix in order to achieve a certain colour/effect/etc., that kind of thing. It's not something that computers use.
I believe what computers do use is hex codes. They're six digit codes that go alongside HTML and other coding languages to identify colours. For example, solid white would be #ffffff and solid black would be #000000, just to name 2 of the many out there.

What should you do before using a website to store student information ? A. Read and understand the website’s privacy contract B. Click the box that allows you to use the website C. Explain to children that you will be using a website D. Only use the school computer to access the website nt information?
For this question, I agree that it's A. It seems to make the most sense, as you are reading how they will use your information and what they're entitled to do with it. But, it never hurts to get a bit more info about the choices on a question!
For B, you're literally just clicking the "I Agree With Terms And Conditions" box without actually reading the terms and conditions. This may lead to your information being shared with other providers, especially email/phone, so that they can send you offers and stuff, among other things, to your spam folder. It's always advisable to at least brush up on a website's terms before giving anyone your primary email address/phone number or any other personal information that you wouldn't give to spammers directly.
C doesn't even make any sense. The child that you tell probably won't know or care about what you're talking about. It's much better to tell an adult that you'll be using the website, not someone who's younger than you and most likely has less experience??
D isn't very good either, since you can still enter information into some website, as long as the website isn't blocked by your school's server.
It probably wasn't necessary, but I hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
I have a couple of questions on java for my homework 21229 Assume the availability of a method named makeLine that can be passed a non-negative integer n and a character c and return a String consisting of n identical characters that are all equal to c. Write a method named printTriangle that receives two integer parameters n andk. If n is negative the method does nothing. If n happens to be an even number, its value is raised to the next odd number (e.g. 4-->5). Then, when k has the value zero, the method prints a SYMMETRIC triangle of O's (the capital letter O) as follows: first a line of n O, followed by a line of n-2 O's (indented by one space), and then a line of n-4 O's (indented by two spaces), and so on. For example, if the method received 5,0 (or 4,0) it would print: OOOOO OOO O Note: in the above output , the first line contains 0 spaces before the first O, the next line 1 space, and so on. Note: These instructions state what the method does when k is zero, but it is up to you, the programmer, to determine what it does when k is not zero and use it for your advantage. The method must not use a loop of any kind (for, while, do-while) to accomplish its job. The method should invoke makeLine to accomplish the task of creating Strings of varying lengths. 20861 A palindrome is a string that reads the same forwards or backwards; for example dad, mom, deed (i.e., reversing a palindrome produces the same string ). Write a recursive, boolean -valued method , isPalindrome that accepts a string and returns whether the string is a palindrome. A string , s, is a palindrome if: s is the empty string or s consists of a single letter (which reads the same back or forward), or the first and last characters of s are the same, and the rest of the string (i.e., the second through next-to-last characters ) form a palindrome. 20864 A 'array palindrome' is an array which, when its elements are reversed, remains the same (i.e., the elements of the array are same when scanned forward or backward) Write a recursive, boolean -valued method , isPalindrome, that accepts an integer -valued array , and a pair ofintegers representing the starting and ending indexes of the portion of the array to be tested for being a palindrome. The function returnswhether that portion of the array is a palindrome. An array is a palindrome if: the array is empty (0 elements ) or contains only one element (which therefore is the same when reversed), or the first and last elements of the array are the same, and the rest of the array (i.e., the second through next-to-last elements ) form a palindrome.
Recursion is something that is probably the most mind warping thing to learn in programming, but it is VERY well worth it. There's a number of problems that are recursive in nature. One that you're familiar with is doing addition with pencil and paper. Think about it: you align the numbers in columns as you're "going in", when you run out of numbers, the base case, you start adding the column of numbers and the carry and write out the least significant digit of the total and returning the most significant digit[s] up the "unwind".
