<p>yeah i remember 10 for B</p>
<p>Was one of the answers all integers with positive squares?</p>
<p>youtubesurfer, i got b, but i was really unsure…anyone else?</p>
<p>to youtubesurfer:</p>
<p>that was real! i think i got either C or D</p>
<p>youtube - it was not experimental
the answer was (2x)^2/2</p>
<p>^
Agree to both</p>
<p>which answerchoice was this?</p>
<p>Wait, did anybody get anything about all integers with positive squares, because somebody earlier said <99…</p>
<p>The question that had 60 as the answer,
(pencil and erasers)
what was the answer choice A,B,C,D,E?</p>
<p>and does anybody remember
what the very last question of the last section was
and what the anwer was?</p>
<p>explanation for 1/K =.13… question:
You were to find (K-1)/K (?) and that turns to 1-(1/K) therefore 1-.13blahblah will always be .8 something</p>
<p>re: that integer problem
Correct me if I’m wrong, but weren’t the conditions</p>
<ol>
<li> numbers are different factors of 40</li>
<li> numbers are ALL odd</li>
<li> add up to 11</li>
</ol>
<p>Can anybody help? Was one of the answers all integers with positive squares?</p>
<ul>
<li>simple1</li>
</ul>
<p>Your conditions are incorrect. The three digit number must be odd, not the individual integers themselves.</p>
<p>With the conditions you set, the problem is impossible to solve.</p>
<p>yeah i think that was the question. could i have said 821? yes, right?</p>
<p>821, 281, 425, and 245 are all acceptable answers.</p>
<p>Is the circle and the slope of tangent line answer 4/3?</p>
<p>I took the derivative of sqrt(25-x^2) at x=(-4) [yeah whatever call me a nerd i dont care]</p>
<p>hahaha</p>
<p>Somebody help, lol. Integers with positive squares?</p>
<p>nevermind.</p>
<p>For the circle and tangent slope, i did this:</p>
<p>The point was (-4,3). The slope of the radius of the circle to the point (-4,3) is just rise/run, which is 3/-4. The tangent line is perpendicular to the radius of the circle at that point. Slopes of perpendicular lines multiply together to give -1. Therefore, slope of tangent line was (-1) divided by (3/-4) = 4/3.</p>
<p>I JUST MADE A DISCOVERY ! I THINK!</p>
<p>I took the SAT back in november, right (i think)</p>
<p>I had the math experimental section, and I just saw someone here write a question that was int he exp section about a regular pentagon in a simple plane, about how many points a circle could touch if it was in that same plane. that SAME EXACT ANSWER was on the experimental section in november, and i had put 2. i thought that because of that experimental section (which i thoguht wasnt experimental) my math score would blow, but i ended up getting a 740 (2 wrong!)</p>
<p>so yeah, maybe they recycle questions in the experimental question?</p>
<p>can this work for anything?</p>
