OFFICIAL January 2013 Math 2 SAT Subject Test Thread

<p>I’m just starting now. What did you guys get for #49 where the ball was thrown at a height of 20 feet after it reached its maximum height? I put 2.5 seconds.</p>

<p>And what about for the one that had a parallelogram with side lengths of 27 and 29 and we had to find the diagonal of it. I think I put 40 but it might be 44?</p>

<p>It’s 1 second because you had to subtract it from the time at the maximum height.</p>

<p>the maximum height one was actually one second i believe because it aske how many seconds AFTER the max height does it reach 20 feet. it was at 2.5 seconds, but since max height was reached at 1.5, you do 2.5-1.5= 1 second</p>

<p>and lol i skipped the parallelogram one. i was so mad because i remember getting one wrong similar to that one on a practice test >.<</p>

<p>Same @basedgod haha. For #2 with the things bought to add up to $9, I got 20 things each.</p>

<p>I guess I’m the average student who just took this test. I left many blank and wasn’t too confident about others. Thank goodness for score choice.</p>

<p>Damn. This sucks. I guess I’ll have to retake it.</p>

<p>same feminist, i got 20 things. do any of you remember the colinear one with the triangle, asking for h?</p>

<p>damn it i forgot to subtract for afterwards, i put 2.5 :frowning: and for the parallelogram i got 34</p>

<p>Basedgod I remember getting that problem but can you say the options because then ill know which was right?</p>

<p>the parallelogram is 34 you get that by using law of cos
did anyone get the function question f(x)= a^x , f(m)*f(n)
anyone remember that question?</p>

<p>@Adeeetz
For the diagonal of the parallelogram, how did you get 40? I got 34 by the law of cosines: sq rt of (27^2+29^2-2<em>27</em>29*cos(75)), since the angle has to be the one between the two given sides and 180-105 = 75. (If you use the 105 angle, you get 44, not 40).</p>

<p>@wwacka
I think the answer was just f(m+n) because of the laws of exponents:
f(m) * f(n) = a^m * a^n = a^(m+n) = f(m+n).</p>

<p>I got k = -1/3 for the maximum value of k for the inequalities problem.</p>

<p>@MelzidEril thank you!</p>

<p>lol no no maximum value for sure it was x-2<1 for hich no maximum exists</p>

<p>@wwacka & critmaster:
For the absolute value inequality, I thought if you divide both sides by 3, you get |x-2|<1/3, so the maximum value of k is 1/3.</p>

<p>Yeah I knew I was wrong for the parallelogram. Oh well. What did you guys get for the matching glove pair problems? It was the minimum that had to be removed to be guaranteed a matching pair?</p>

<p>I got 4 for the gloves question</p>

<p>i got 4 tooo</p>

<p>@jermeylin12 i got 3</p>
