So the first thing you need to know about HTML is there are many different versions, as Hypertext Markup Language has evolved since it was first created. The answer to the question, secondly is a doctype declaration. This is an instruction that associates a particular SGML, or Standard Generalized Markup Language. What you're doing with the doctype declaration is Declaring that it is an HTML markup document, as there are a number of different markup languages for web pages. One thing you should understand about HTML is how web-pages load. Imagine loading a web page as the user's computer browser having a conversation with the Host site. What is the first thing you do after you open your browser? Type in a web page URL (or address, if that makes it easier to understand). So you, the user, type in a URL and that sends a request to the Host and the host returns this web page but your browser has a bunch of different questions its going to ask so the page loads correctly like, "Okay, cool I got a response and here is this incoming document... well before I can show the document I'm going to need to know what kind of document it is!" So, a basic rule of thumb for coding in HTML that you will learn in any intro class on HTML (and usually CSS is included in that), is you always start with the tag:

<!DOCTYPE html> (which is always followed by:)

<html>

So the two examples I just showed you above? Those are what are called "Tags" or rather, a "Tag". If the question you posted was a multiple choice question... it's pretty silly that "an tag", "a tag" and "a tag" were all options... seeing as they repeated "a tag" twice, and "an tag" is just improper grammar (ha ha... unless it was just a typo, in which case my bad I wasn't poking fun at you in any way). But the short answer to your question is:

"A doctype declaration"

I hope you enjoy your HTML class! That is the first coding class I ever took and I have to say that it opened the flood gates for me wanting to learn how to code! If you are working out of a text book, the answer should be in there and I strongly encourage you to read it and give coding a chance! Once you get the basic principals down its actually one of the simplest languages to learn, but with that comes endless possibilities for creativity!

Best of luck in your studies,

Retype the statements, correcting the syntax errors. system. out. println("num: " + songnum); system. out. println(int songnum); system. out. println(songnum " songs"); note: these activities may test code with different test values. this activity will perform two tests: the first with songnum = 5, the second with songnum = 9. see how to use zybooks.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x, y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
