January 2012: Math Level 2

<p>Does anyone remember the five answer choices to x^2 < 4??</p>

<p>**bear111<a href=“A”>/B</a> abs value of (10t-60)</p>

<p>Can someone explain why it’s absvalue(10t-60)?</p>

<p>I second hkim’s request for the five answer choices to x^2 < 4</p>

<p>What was the answer to the problem about f(x)=(3x+2)=x?</p>

<p>what question was 1/pi^r? i remember only getting 1/pi</p>

\Wife travels t-1 hours at 6o mph, so has gone 60(t-1) miles
Husband travels t hours at 50 mps, so has gone 50t miles
difference = miles between them = abs val(60(t-1)-50t)=abs val (10t-60)</p>

<p>**bear111<a href=“E”>/B</a> (x-2)/3</p>

<p>Anyone remember the question about bacteria?</p>

<p>yeah i said the biggest one</p>

<p>catcat18:
do you remember the question or the (numerical) answer?</p>

<p>I second cat</p>

<p>I second cat
It was y=_(1.1)^x i believe</p>

<p>What was answer to the 2n/6 problem asking which is an integer?</p>

<p>bear
2n/3</p>

<p>Three more questions I just remembered:
Average of remaining scores
Parabola opening up
Which equal 1 (trig)?</p>

<p>Hiking
Can you explain plz?</p>

<p>I know I got one question wrong (the one where it was infinitely many lines… for some reason I put 2 -.-) so far, but overall I felt this was a little bit harder than the blue book , much easier than Barron’s, a little easier than PR, and about the same as Sparknotes. Hoping for an 800!</p>

<p>bear
2n/6 = n/3 = integer so double that will be an integer, too.</p>

<p>Parabola was a>0
I said only first equation = 1</p>
