September 2010 ACT Math Discussion

Test Preparation ACT Preparation
1

<p>This might be a bit early but I thought I would make this thread now so no one gets a chance to post it under an ambiguous title tomorrow. Discuss all Math questions here after the test tomorrow. Good luck to all! :)</p>

2

<p>When is the embargo lifted!?!?!?!?!!? I would like to know the 2x and x^2 problem (doesn’t give anything away). PM me??</p>

3

<p>RAlec, i don’t think here is an embargo for the ACT.</p>

<p>Can you type out the problems, maybe i can help you figure them out? (i didn’t take it today)</p>

4

<p>your talking about the one that said which one is not rational in terms of pi. i guessed tan x
2^x
tan x (in terms of degrees)
sin x (in terms of radians)
square root of pi</p>

5

<p>Hm. I will wait till after pacific time finishes the test to publicly post the question.</p>

<p>Mark I would PM you but I can’t exactly remember the question, besides the 2 equations</p>

6

<p>^Answer is sinx</p>

7

<p>Didnt it say which is rational???</p>

<p>I put sinx</p>

8

<p>Same, sinx would make it 0, thus becoming rational.</p>

9

<p>What was the value of a?</p>

<p>can’t remember the first part</p>

<p>6x^2+ax+10 was the second part i think </p>

<p>didn’t have time for this one</p>

10

<p>There is a question asking about 5 distinct points and which polygon will give you the most connected lines?? </p>

<p>I put Pentagon…</p>

11

<p>I think a was 11</p>

<p>and **** I didn’t realize it was a POLYGON. I put circle for the answer :(</p>

12

<p>i put pentagon to… was scared it might have been circle and dang for that i put tanx because i thought 0 was not rational MAN I AM MADDD</p>

13

<p>^HelloHelloKitty: It was the circle. If you draw the pentagon and put the points on the vertices you will only be making 2 lines, whereas you have a constant 4 lines with the circle.</p>

<p>^infinite: It was -11.</p>

14

<p>Yea, that’s what I meant. </p>

<p>billa, I think it asked which POLYGON</p>

15

<p>It said geometric figure (not polygon) I think, so circle would work.</p>

16

<p>Yeah, pretty sure it said geometric figure or shape. I picked circle.</p>

17

<p>Well a circle is DEFINITELY not a polygon :/</p>

18

<p>

</p>

<p>Didn’t it say “geometric figure”?</p>

<p>

</p>

<p>Um… I think your geometry works differently than mine. 0.o Then again, I put pentagram, though it was pretty much a guess.</p>

19

<p>I put circle</p>

20

<p>Was #57(the question about the slope of the LOBF), A?</p>
