4. Calc 2

Two things you need to know: 1. csc x = 1 / sin x 2. lim as x->0 (sin x / x) = 1 See if you can simplify your question using these equations, and arrive at an answer (which I think is not 0).

5. arithmetic

Use these to figure it out: Area of a square = (length of side) * (length of side) Perimeter of a square = 4 * length of side Difference, I hope you know, means you subtract one value from the other. :)

6. arithmetic

The average of a list of numbers = sum of numbers divided by (how many numbers there are) So what you're looking for is: sum of angles of a triangle divided by (how many angles there are in a triangle) (I'm hoping you can fill in the values yourself)

7. arithmetic

Actually, since you posted this as arithmetic, let me try to give an explanation without algebra. Let's say you just had 1 of each coin. Then, you would have a total of 0.25 + 0.1 + 0.05 + 0.01 = 1.23. Now if you had any other number of each type of coin,

8. arithmetic

Let's say you have x number of each type of coin. Then, the total amount you have, in dollars, is 0.25x + 0.1x + 0.05x + 0.01x = 1.23x. Since x is a whole number, the total amount you have has to be a multiple of 1.23, which leaves one of the options you

9. arithmetic

Let me give you a hint. Think of all the different ways in which you can add three whole numbers (the lengths of the three sides) to get 6 (the perimeter). You'll find that there are 3 ways to do that, of which 2 will be invalid because of a certain

Haven't done real science in a while (studied computer science in college), but I'll give it a shot. I hope you actually want to learn the concepts a little bit (if you just wanted the answer, you could probably have googled the questions), so I'll explain
