<p>Please correct the range to 3-6.</p>
<p>Also, what was the line translated (-4,-3) question about?
All I remember was that P couldn’t be transformed to the point D position…unless that was a different question.</p>
<p>I had x^(1/2) not x^(-1/2). Does anyone remember the question?</p>
<p>I see you have 196 as a grid in answer, does anyone know what problem that was for? I can’t remember if I got that exactly.</p>
<p>
</p>
<p>something like</p>
<p>rad(1/x) ?</p>
<p>It was definitely x^(-1/2). </p>
<p>For negative exponents, you get the reciprocal of the number (in this case it’s 1/x) and then you remove the negative sign from the exponent. It would be (1/x)^1/2 which is the same as the square root of 1/x.</p>
<p>Um… the three circles. Made me rage. What was the answer?</p>
<p>um for the 666 one, why wouldnt it include 1000?? i dont think it said excluding 1000</p>
<p>Could you get 1 grid-in wrong, everything else correct, and still possibly get an 800?</p>
<p>the sum of the odd numbers up to that number. (box)100-(box)96</p>
<p>so it’s 99+97=196</p>
<p>it said less than 1000.</p>
<p>3 circles. i said 6/7. can anyone confirm?</p>
<p>possibly. depends on the curve.</p>
<p>did any1 get the square root of X+y for 1 of them</p>
<p>because it said less than 1000 and yes it was 6/7.
And no there is no curve, you get 1 wrong you don’t have an 800. Grid-ins don’t mean anything except for the fact that they don’t count towards the penalty which only makes a difference if we’re talking about -3/-4 in which it would mean an extra -1.</p>
<p>kmtt, I got 6/7 too.</p>
<p>Yup i got 6/7</p>
<p>of course there’s a curve. there’s always a curve.</p>
<p>Three circles:
R1, R2, R3</p>
<p>R2 = 1/2 * R1
R3 = 1/3 * R1</p>
<p>Pi * R1^2 + Pi * (R1/2) ^2 + Pi * (R1/3)^2 = Pi
R1^2 + (R1^2)/4 + (R1^2)/9 = 1
36<em>R1^2 + 9</em>R1^2 + 4<em>R1^2 = 36
49</em>R1^2 = 36
R1^2 = 36/49
R1 = 6/7</p>
<p>can any1 elaborate on wat this question was asking:
7.5 or 15/2 // two similar equilateral triangles with the same base and you had to find</p>
<p>I had math experimental, and would like to know which one:</p>
<p>Section 1: Essay
Section 2: CR
Section 3: Math
Section 4: Math (Grid-In)</p>
<p>I am hoping section 3 is the experimental. Can anyone confirm? I remember one of the questions, number 17 I think, said something about a function, and it listed numbers in two lines…something like this(these numbers are similar, but not correct, i made them up):</p>
<p>(0,1,3,4,6)
(1,2,4,6,7,9,10)</p>
<p>And then all of the answer choices started with f(n) = bla bla bla. One of them i think was f(n) = n^2…IS THIS SECTION THE EXPERIMENTAL?</p>
<p>There were two triangles, one inside the other. </p>
<p>The smaller triangle was a portion of the larger triangle’s base.</p>
<p>The base was <strong><em>2</em></strong><em>/</em><strong><em>6</em></strong><strong><em>/</em></strong><em>1</em>___</p>
<p>I THINK? So that comes out to 9</p>
<p>The left side of the triangle was 6.</p>
<p>So 6/9 = Some proportion</p>
<p>Sorry, I can’t remember more</p>
<p>Honestly, who cares if you don’t get an 800 on the math. I highly doubt that a school would care that you didn’t ace the math section.</p>
<p>Last time I took the SAT (first time) I didn’t do so hot in the math section (pretty good in CR and Writing though), so I was just hoping to get a “good” score. </p>
<p>I only left two math problems blank (the damn surface area one, because I didn’t realize it said surface area until the last minute and just erased what I had down (the volume) and also that uphill downhill one) and it seems from this thread that I got about 3 problems wrong. </p>
<p>All this talk of curves is scaring me, How many wrong would you have to have to get below a 700?</p>
