September 2010 ACT Math Discussion

<p>@Linger I got square root of 40</p>

<p>Yes I believe the sequence could be modeled to the function f(x) = 2x + 1 (correct?) so f(25) = 51</p>

<p>It was sqrt(40) and 136 / 480.</p>

<p>If she reads the book in 5 days adding 20 pages each day how many % of the book did she read on day 5</p>

<p>something like that</p>

<p>

</p>

<p>OK good I did as well but I kinda just eyed it. LOL i forgot the distance formula</p>

<p>The 480 book page question was something like 12% or 28% I forget the exact answer.</p>

<p>480 page: 56 76 96 116 136 136/480</p>

<p>^28% for the book problem, if I remember right. I definitely did guess and check with my calculator. lol</p>

<p>In the answer choices for the circle question, wasn’t (x+3) in only ONE answer choice?</p>

<p>The polar coordinate one? I Forgot polar coordinates and I don’t remember which answer I put (either 1 or 3)</p>

<p>I believe it was. Coordinate was in quadrant 3.</p>

<p>I said Quad 3 for the polar coordinates</p>

<p>yeah what was the polar coordinate one?</p>

<p>i put third quadrant…</p>

<p>ya quad 3… just radius 2 (which doesn’t matter) and 2xx degrees put it in quadrant 3</p>

<p>edit: bleed read my mind. ahhh i completely forgot about that. whats the most you can get wrong for a 36 in math?</p>

<p>Does anyone know the one with two parallel lines and a triangle in between them and it asked you to find the measure of y?</p>

<p>yeah what was the answer for the polar coordinate plane problem?</p>

<p>R was something, angle was 230 degrees. Rcos(230) is negaive, Rsin(230) is negative, thus the point is in quadrant III.</p>

<p>iPhone it’s 55 degrees.</p>

<p>@iphone</p>

<p>I think it was 55</p>
