November 2008 SAT Subject Test: Math Level 2

<p>@lolilaughed</p>

<p>No its not. xD</p>

<p>Thats a good 760 minimum. Thats good enough for admissions almost anywhere, it sure won't be a black mark on your test record</p>

<p>I remember one more it was like y = 3^-x + 1, as x increases, what value does y approach. Was the answer like 1 or something?</p>

<p>Yeah.. bleh. 780+ you're fine. 750-780 is iffy. Less than 750 = retake, ESPECIALLY for Math2. 5 Omit, 1-3 wrong.. is that aboe 770, 780?</p>

<p>@WantIvy that's about 770 to 800.</p>

<p>@quickandslowly</p>

<p>Yes it was 1. Cause When x is infinite, that term is zero, plus 1 equals 1.</p>

<p>^ Added the question. :/ just everybody here gets 800 I'll feel left out D:</p>

<p>@WantIvy</p>

<p>Depends on the curve. Sounds about right... However I always figure a very harsh curve on everything until I am certian otherwise. BTW, I omitted the same amount, got somewhere about that many wrong too. Got 630 my first sitting though, donno *** happened then...</p>

<p>Alright thanks crcowboyfan! That's a relief.</p>

<p>Here is a consolidated list of the thread</p>

<p>(x^2-25/x^2-5x) undefined at x value: x=5, or **x=5,0 (does 0/0 make it undefined)?*</p>

<p>equilat triangle P=6: 1, -rt 3</p>

<p>y>2x^2-1: (1,2)</p>

<p>Period of |sin x|: answer 2pi or * pi **</p>

<p>f(x+2) graph shift left: y-inter (0,4)</p>

<p>? Similiar triangles sin A/sin B : 3 or 6</p>

<p>Boxplot graph, I - greater means A>b, II - standard dev, III - range: either I only or **I & III*</p>

<p>(x-3)^2 + y^2 =11. (x+2)^2 + y^2 = r^2.: answer: 1.68 rounds to 1.7</p>

<p>find NON-NEG productive of zeros: answer: Non Negative product of zeros is x(x+6) b/c 0 times -6 is 0, which is a Non Negative number.</p>

<p>probability question about numbers whose sum is 10 and product is 20: 1/2 (ab=20 and a+b)</p>

<p>3^x + 1 as lim of x approaches infinity: 1</p>

<p>? lim as x approaches infinities for func of 3x^2/?: ?</p>

<ol>
<li><p>Probability -1<x<1: pi/4</p></li>
<li><p>Parallelogram question: 53</p></li>
</ol>

<p>Boxplot is I and III by the way</p>

<p>There was one about what's the domain of something/x^2+5 or something and the answer was like x cannot equal 0 or (5 or -5..I don't remember, but it had 5 in it).</p>

<p>Anybody remember the question with the 3x^2 w/ a somethingx^2 on the bottom and you find infinities and get coefficients of the highest power?</p>

<p>? lim as x approaches infinities for func of 3x^2/?: ?</p>

<p>^ JJJJ1234 thanks, edited.</p>

<p>Don't forget the sum of x and y= 10, product = 20 one! Answer was 1/2 and it was either Q# 46, 47 or 48</p>

<p>Similiar triangles sin A/sin B : 3</p>

<p>Wasn't it six?</p>

<p>x^2 -5x
= x(x-5)</p>

<p>It's undefined at 0 and 5. 0/0 is still undefined.</p>

<p>Another Problem</p>

<p>there was something with 3 is a factor of x^3+18x^2+11x+c or something and you had to find c. The answer was -21.</p>

<p>@ hipster, I don't know; I skipped that problem :P</p>

<p>@ crcowboyfan: Yea, that's starting to be what I'm thinking to D:</p>

<p>"Anybody remember the question with the 3x^2 w/ a somethingx^2 on the bottom and you find infinities and get coefficients of the highest power?</p>

<p>? lim as x approaches infinities for func of 3x^2/?: ?"</p>

<p>I have NO idea what you're talking about lol. I don't remember that question at all :O</p>

<p>Edit: Hipster, it was definitely 3.
sinA/sinB=3. Law of Sines: SinA/6 = sinB/x x= 6<em>(sinB/sinA)=6</em>(1/3)=2. </p>

<p>Then proportions, 2/6=x/9, x=3.</p>

<p>And it was 5 and 0, pretty sure.</p>

<p>is -4 a 800?</p>

<p>i still don't get why its 113 rather than 112.5 for the sum of the first 225 integers problem. can someone explain?</p>
