<p>I have no idea where else this can go, I know Regents is only NY, but we NYers can still discuss it hopefully.</p>
<p>What'd you guys think? Drop some questions/answers. Also discuss what you did on the proof, because that gave me some trouble.</p>
<p>I’m lost on the proof also. I got AAA=AAA but apparently that only proves similarity. Everything else was pretty easy though.</p>
<p>that proof was tough, i got the jist of it but didnt get it 100%. pretty sure it was an isosecles trapezoid were the diaganols are equal so halves of equals are equals?</p>
<p>my way seems out of the ordinary
but i used alternate interieor angles, then congruent arcs, then like inscribed angles of congruent arcs are congruent, transitive property, base.angle theorem (opposite sides of congruent angles are congruent)
does that make any sense lol</p>
<p>didu guys get 40 for tangent tangent angle? 459/512 for probability?8200 for area of triangle? 24+8sqrt2+8sqrt3 for perimeter? 3 for logarithm? 0.42 for sin B? Quad III for the sum of the two complex numbers? 103 for regression question (projected total for 2009)?</p>
<p>proof was very unfair considering every proof ive ever done in geometry and during review this year wasn’t challenging. the regents should reflect that… i breezed through the whole test and spent 2 hours on the last question and still (likely) got it wrong. it was way too confusing for the average person to even half ass… i had to make up some random proposition that was, although true, something i was never taught (that when you connect the parallel chords in a circle to form a trapezoid, the line segments are congruent, making it an isosceles trapezoid; then i said diagonals of an isosceles trapezoid are congruent and that the center cuts the diagonals into equal segments). it was one of those questions where the answer (or rather my answer) sounded right in your head but was unfamiliar and hard to make sure of</p>
<p>oh and question, were we allowed to use the blank sheet at the end of the test (between the last question’s page and the formula sheet) for the answer?</p>
<p>will the curve reflect the toughness of the last problem ( the proof)?</p>
<p>i’ve done the whole red book of problems and even though it wasn’t impossible that one was the hardest.</p>

<p>yes for all but not 8200, it was 8181 and some 2 decimal places (it sound round to the nearest hundredth i think?)
and i dont remember if the tangent angle was 40 but it was the the difference between the arcs divided by 2</p>
<p>i never heard of a regents curve. but if there is then obviously it will be bigger if a lot of people found the questions difficult</p>
<p>yea the curves supposed to be very very nice.
I got Quad III for the sum question, and for the proof i got A.A.S, and 103 for the regression question. For probablity i got 918/1024,I totally got the perimeter question wrong.</p>

<p>it said nearest hundred, 8200 (im pretty confident it ssaid nearest hundred. i got 8181 as well, but i rounded to 8200)
918/1024 is 459/512</p>
<p>did u guys get 720x^3 (not -720x^3) for the expansion q?</p>
<p>damn if it was hundreds place and not hundredth. yes i got 720x^3</p>
<p>I got all those answers that were posted.</p>

<p>And the 720x^-3</p>
<p>I’d say, seriously, the only tough question was the proof. Last Math B Regents and they HAD to put a proof… Hopefully I got 4/6 points.</p>
<p>Combination one:
[5C0 (1/4)^0 (3/4)^5] + [5C1 (1/4)^1 (3/4)^4] + <a href=“243/1024”>5C2 (1/4)^2 (3/4)^3</a> + (405/1024) + (270/1024) = 918/1024</p>
<p>Rx-axis o Ry=x (triangle graph q)
do u do Ry=x first or Rxaxis first
i did R xaxis 
but others have said otherwise</p>

<p>Wow, I’m ****ed, I was rushing through the multiple choice and got the determinant question wrong. >.></p>
<p>Also got the simplifying the fraction wrong and proof (Probably 1-2 points off for both) So about 82 - 84 Raw, 94-96, not too bad.</p>

<p>was the determinent q real, irrational unequal?</p>
<p>Yeah, it was. In a rush, I put real, rational, unequal T_T</p>
<p>the thing u showed me has sum q wrong i htink.
it was 720x^3.</p>
<p>for Rx-axis o Ry=x
which do u do first :(</p>
<p>That was the only one incorrect
You do ry=x first, you go right to left.</p>
