In how many overall outcomes do at least 2 of these students select choral tracks?

I figured out the first question: 17^6= 24,137,569. Can someone please help me with the last two questions?

I have never done the relationship thing. When I like someone, I go straight to him and we go out and stuff but I ALWAYS eventually get bored. I get annoyed instead of flattered when someone sweet talks to me or gives me compliments, and even if he flatters me, it goes away really soon. I've dumped a guy before as soon as he mentioned the word "marriage". And honestly, I can only picture myself in a relationship with one guy I have met in the past, but he is in a relationship now.

I used to think that I had a fear of commitment, but now I think it might be something else.

Please don't be rude, I really want to figure this out for the future

I know the first part is 25x^4 but i don't get how to get the derivative of (2/6x)

can you explain how to get it?

I hear people sneeze in all kinds of ways, and if i try to do another way, I can't.

why?

a) 9e^-4x

b) e^-2x + 8/x + 3x^2

c) 12x^3/x^4+9

d) 9e^(9x+6)

Please help me =( especially with the last two... i'm lost if you dont know all of them you can just help me with one. Thanks

a) -6sqrt(x)

b) -7x

That movie about a psycho barber who kills his clients. I heard a lot about it; a musical, horror and thriller movie.. I love Johnny Depp movies, but this movie just sound bizarre. I have watch series with these kind of crimes but watching a movie is a whole different thing

so..anyone recommends it?

In the trailer there are scenes that dont appear on the actual episodes. When they are playing in the yard as kids and when cecilia tells lucia that luis loves another woman. Was it supposed to be like that? Or do they actually show it?

I met this boy when i was in the 4th grade and liked him since, everyone in our grade always teased us and we kinda liked each other in 6th grade. I moved out of the country when i finished 6th grade and came back 4 years later, i saw him again and i thought he only liked me as a friend so i ended up dating another guy and LATER i found out he actually liked me =\ we still talk online and he talks to me like he has always talked to me; in a flirty yet friendly way. It's been four years since i saw him and i'm going this summer back and I'm going to see him again.

Thing is, it's been like 10 months since he has been dating this girl. When i found out he was, i was a little heartbroken but he never changed the way he talks to me. He's like my first love so every time i see him, no matter the time, the feelings come back. So my question is:

any advice on how to get over him, or how should i act when i see him again, or when i see him with his new girlfriend..i've never been in a situation like this, so ,i need some advice =(

I just don't know what to tell her... what can i do?

find the value of a so that the function f(x) = xe^(ax) has critical point at x = 10

i like this boy since i was a child. we were really attracted to each other by the time were 16, but i had to move to another country. Now, i'm going back to visit my hometown this summer and when i told him he got really excited. My best friend, who talks to him a lot, told me that he still has feelings for me, but that was before he started dating this girl. They have been dating for a while now and i really want to see him when i go there.

What if he's still dating her when i get there, how do i deal with these feelings. i like him since i was a lil girl, what do you suggest i do to get over him? I have had boyfriends and all but since he was my first love, feelings come back when i see him. what do i do? =(

US inflation rate had been 3.4 % per year and the Argentinian inflation rate had been 21 % per month.

(a) What is the yearly equivalent of Argentina's 21 % monthly interest rate?

(b) What is the monthly equivalent of the US 3.4 % yearly interest rate?

Pretend the program in Senegal had been reducing infant mortality at a rate of 12 % per year. How long would it take for infant mortality to be reduced by 30 %?

I tried 2.5, but that's not the answer =S

1. assume the substance was reduced by 15 % in 30 hours.

What is the substance's half-life?

2. assume the quantity decreased by 7.6 % in 6.9 hours.

What is the half-life of the substance?

3. Assume the substance was reduced by 15 % in 30 hours.

What is the substance's half-life?

Assume the half-life of the substance is 26 days and the initial amount is 195.9 grams.

(a) Write the equation which expresses the amount A of the substance as a function of time t (the coefficient of t in the exponent should have at least four significant digits):

(b) When will the substance be reduced to 2.5 grams?

19 e^7t = 18 e^10t
