Was the section with the question 3^(x+1) = k (or something along those lines) an experimental section??? Thanks.

It was just a typo. Either way I got the answer right. 2x10^4 and 3x1^2....4+2=6

The answer to the 3^(2x + 1) question was 3k^2.

3^x = k

3^(2x + 1)
= 3(3^2x)
= 3(3^x)^2
= 3k^2

Yeah, but was that question part of the EXPERIMENTAL MATH section?!

@chosen00, i feel like it isn't. as far as I've seen, i think almost everyone had that question

3k^2 was not experimental.

ShadowMist

I don't remember that 3^2x+1 one, but by now I've forgotten a lot of them.

And yeah, I meant to type 20,300 for that a+b one. Whatever the number was, it was still 6. LOL.

Are these experimental Math questions:

1. Find the fraction of the volume of the smaller cylinder to the whole thing.... It was like a cylinder within a larger cylinder or something like that... The larger cylinder had like side length 10, the other had side length 5.

2. There are n numbers in a list that consist of only 3s and 5s. The mean of the list is 4. What could be a possible value for n? ( I, II, or III)

3. Find perimeter of the triangle that is equilateral and has an area of 1... or something like that ( this was one of the last problems in the section #18,19,or 20) NOT the maximum perimeter of triangle question that was 33... I had that in another section.

4. Problem where you have to solve for (a) that was in f(a)... They said that a does not equal 5... So you had to factor it out and set equal to 0... So it was like (a+1)(a-5) ... So the answer was like a=-1

6.2(any number between 6 and 7)
2:1
(-1,3)

2xroot3
1/8 humback whales
x+y was the greatest
x+y+z < 270 (or something like this I can think I put E for this problem)
3 solutions for the 10 = 3x (something like this)


These are 30/54 answers I can remember. I am fairly certain they are right, but feel free to disagree.

^ What's the question for (-5)?

Also, you can add the x = 70 degrees problem and the 2B8/11 has a remainder of 7 question.

ShadowMist

Thanks for finally making a compiled list!

Also, I think you meant 9/22, not 22/9.

rk10231994

ahh yes, I got 7 for a remainder problem, and @shadow mist I did mean 9/22, and the (-5) one was like the first problem, thats the only reason I remember it.

and @studio I believe it was x = 65 degrees unless I am thinking of a different problem?

StudiousMaximus

^ Pretty sure it was -3. 9 + (-12) = -3.

No, y = 65 degrees and x = 70 degrees (one with two isosceles triangles).

Also, you can add 998 (the number in the (3, 8, 13) sequence).

rk10231994

Yeah I remember that one too, I am talking about the one where it was like "which one is not between -4 and 3. and it was -5. And can you refresh me on the x = 70 degrees I am drawing a blank on that problem
