<p>do scores come out oct 24?</p>
<p>i got 5.7minutes for the one on the test.</p>
<p>Yeah I might have gotten something similar.</p>
<p>@Presidont
Wasn’t the initial speed 60 mph? I think I put E on that one. I did a ratio between the first stopping distance/speed^2 and set that equal to the second half of the question.</p>
<p>That wasn’t the exact Math II question, but one from the SAT Question of the Day archive.</p>
<p>4 omit, 2 wrong
whats that?</p>
<p>was it me or were there no limit questions, no logs i think, and like 1 trig identity…i didnt even touch my ti-89</p>
<p>1 trig identity…I used logs once for something. I don’t remember what.</p>
<p>Some interest rate problem. Anyways I think I’ll stop watching these threads before I get too despondent; it’s not like anything can change.</p>
<p>screw the stupid ladder problem with the “round to nearest inch.” damn it.</p>
<p>i thought the testing pressure would get the blood running but i could not focus even if my eyes were glued to the paper. it was getting me all worked up. shaking my head to wake myself up in the middle of the test, although probably no one noticed since everyone likewise was on the test like white on rice. sucks, i have to retake. my mistake was bouncing around the test too much and not getting problems done.</p>
<p>i omitted 11, ill say 5-6 wrong. thatll be somewhere between 680-710. right?</p>
<p>does anyone remember the k(k-4)=3t question?</p>
<p>^ was it t= 0?</p>
<p>…what was that question? o-o</p>
<p>It asked what value of t would grant only ONE real solution…</p>
<p>I said 0 as well, no clue if that’s right.</p>
<p>I dont’ even remember what I put, but I remember solving it like this:</p>
<p>k(k-4)=3t
k^2-4k-3t=0
16+12t=0
-16/12=t
-4/3=t</p>
<p>How did you solve for k there…?? I don’t see how you went from k^2 - 4k to 16.</p>
<p>I used the discriminants. There is a theorem that you use with b^2 - 4ac to find the type of roots. if the discriminant (b^2-4ac) is equal to 0, it gives you a single root.</p>
<p>I think the only one that produced ONE REAL solution was choice a) -4/3
I used “solve(” on my ti89 and plugged in each one, and found that -4/3 was the only one that produced one real answer. 0 produced 2 real answers.</p>
<p>yeah, superexcited is correct.</p>
<p>CAN ANYONE PLEASE PLEASE TELL ME WHAT THEY GOT FOR THE LADDER Q?
I used the angle 69.9 because that would give the shortest hypotenuse and cosined it.
IS THIS FINE?? PLZ</p>
<p>and what was that distance and time thingy? 40mph, 60mph distance 20…
PLZ TELL ME HOW THEY SOLVED THAT! did the final calculated answer had to be changed to seconds or something? I don’t REMemBER!!! panik mode</p>
