Algebra 2 question! anyone who gives the right answer first gets the points!?

Hi,

If the order is important, then 20nPr5 = 1,860,460 ways <==ANSWER

If the order is unimportant and the teacher simply selects a group of 5 out of 20, then 20nCr5 = 15,504 <==ANSWER

I hope that helps!! :-)

Algebra 2. Domain, functions, range,?
A certain calling card gives the following rate to call Malaysia. There is a connection fee of \$0.39 which allows you to connect for up to (but not including) one minute. For each additional minute or part of a minute, there is a \$0.24 charge. (For example, 1 minute up to not including 2 minutes cost \$0.63.) This fare is only valid for up to (but not including) 40 minutes.
1) Express this info as a function, where f(x) represents the amount of money charged and x represents the number of minutes which have elapsed.
2)what is the domain for this function?
3)What is the range?
4)What is f(2.5)? What does this value represent?
5)Is this function one to one? How do you know?

LOGIRITHIAMS - ALGEBRA 2 - HELP - easy- expanding - easy best answer!?

hey.. i don't really care about best answer.. and don't really think that i want to take out a pen and paper to do this .. try the following:

1. Simplify whatever is inside... it seems that u have a lot of mess within one log.
2. If i am not wrong .. the final answer will be a difference of 2 logs... that is why i am telling you to simplify both ur numerator and the denominator.
3. hope this helps.

I am in Algebra 2. Should I take Biology, Chemistry, or Physics first?

I’m answering this with the assumption that you’re a high school student in the United States. I’m also answering with the caveat that high school was nearly 20 years ago, so things may have (almost certainly did) change.At this point, if you can take any at any time, follow your interests. My high school biology class was very focused on structural biology - dealing with individual organisms and how they were similar and how they were different in their larger structures. We looked at the large-structure differences between bivalves, verterbrates, anthropods, and echinoderms. Basically, this meant a whole lotta dissections. There was effectively no math.Chemistry in high school was more focused on techniques, but I didn’t really absorb anything. I even took AP chem and was a little lost for years. I’m still not very confident about my chemistry knowledge or my skills. I think that was more about the style of teaching and the few other students in the class who LOVED to distract the teacher (“what happened on Babylon 5 last night, Brother MacDonald?”). Mathematically, there wasn’t much, if I recall.I loved physics. I still do. But at the high school level, we were very focused on Newton’s first 3 laws of motion and Galilean relativity. It was very, very classical physics, and translate to about the first semester to semester-and-a-half of a college physics sequence. For me, it wasn’t calculus-based, and didn’t require anything more than trigonometry and algebra.So, what should you take? Up to you. Algebra 2 will prepare you for any and all of these classes. Typically, students go biology first, then chemistry, then physics, because the math requirements kind of go in that direction.

Is it better to learn linear algebra before abstract algebra?

Formally speaking, around the build-up of pure maths knowledge, it is unnecessary.That said, most undergraduate programs are designed around the sequence of linear algebra-(and then)-abstract algebra, as opposed to the other way around. This means that your School may not even allow you to learn this material in the other order. Also, many courses require a little linear algebra - e.g., Ordinary Differential Equations, Probability, Real and Complex Analysis, Graph Theory, and etc.. So, even if it is allowed to take linear algebra later than abstract algebra, avoiding learning linear algebra for a time will likely put you at a disadvantage in those other courses.Another point to ask is, why would you want to do this? Linear Algebra is a subject that literally has impact in almost all areas of mathematics: you do yourself a great disservice by not mastering its contents at the earliest possible chance. (It is the case though, that the course can be quite boring, and highly calculation based, if not taught by a good professor).Under no circumstances would I respect a math graduate’s knowledge base if they did not have linear algebra behind them: it is simply too fundamental.

Algebra 2 help?

I've been teaching myself math over the summer and this set of questions about this specific ellipse doesn't make sense to me. Can someone explain to me how to get the answer and what that answer is? Thanks.

4x^2 + 9y^2 - 8x + 36y + 4 = 0 is the given ellipse.

1. What is the length of the major axis of the ellipse?

2. What is the length of the minor axis?

bunch of math lingo there, hopefully someone is educated enough to help me out! Thanks! I will award the most thorough answer best answer asap.
