<p>The answer should be 0 real roots for the least possible distinct roots in the polynomial expression AX^5 + BX^4 + CX^3 + DX^2 + EX + K. If A=0, B=1, C=2, D=3, E=4, and K=5, the graph never crosses the x-axis. Since 0 is still rational and x^4… is still a polynomial expression, there can be a minimum of 0 roots.</p>
<p>some of that list is wrong</p>
<p>The answer is one.
0 positive roots.
5 or 3 or 1 negative root.</p>
<p>The midpoint question was (-4,-6)
the midpoint was (2,3) and the other point was (8,12)
(x+8)/2 = 2 (y+12)/2 = 3
x+8=4 y+12=6
x=-4 y=-6
(-4,-6)</p>
<p>@Niceboat</p>
<p>the coefficients can be 0</p>
<p>that would lead you to have a graph of y = a number, which is a horizontal line.</p>
<p>For the questions with the Ax^5+Bx^4… and so on, the least roots can equal 0. It said that the coefficients can be rational numbers and if the A in front of the fifth degree polynomial was 0, a rational number, it would make the graph a 4-th degree polynomial which need not intersect the x-axis at any point. All the roots can be complex with no real roots. Correct me if I am wrong, but i’m almost sure its right.</p>
<p>I remember a question that asked something like if tan=1 and the angle is positive what angle it would be? I know the answer is pi/4, but I’m just trying to help us remember all 50 of the questions.</p>
<p>There was an indeed a question asking for a value x where sin x = cos x or something like that. I put pi/4 for that one.</p>
<p>For this test, how many questions did you guys leave blank? Some of you seem like academic monsters, but for someone who its shooting for a 700+, how many could i theoretically leave blank (assuming that most of the questions answered were correct). I know a couple that i answered incorrectly, but for the most part, the test wasnt as horrible as expected.</p>
<p>@ Roseoak.</p>
<p>The tan=1 triangle question is #38</p>
<p>For the one about sin and tan, I got -.779. Does anyone else remember an answer like that on the test?</p>
<p>2 intersecting sphere is a point and circle, I think we can confirm that. </p>
<p>Cos x = cos (2pi -x)</p>
<p>@Eric335, scaled score of around 35 is a 700 on the dot. Depends how many you left blank / got wrong, but you should be fine!</p>
<p>I do!.</p>
<p>I shall add</p>
<p>@Eric335 If you missed 4, that would means you have 45 - #Qs-omitted for your raw score. That menas you could have missed ~9 or fewer questions to get a 700+.</p>
<p>the number N subtracted by 4 was 1, not -1</p>
<p>Why is the range question 13 not 8? What’s the box for then?</p>
<p>@johnstucky</p>
<p>Damn, i wish i had been motivated/known about the test and studied more. Any more opportunities to take SAT Subject Tests before Early Decision applications roll out? (specifically UPenns which closes 11/1 i believe)</p>
<p>wait what was the “log and expo problem”?</p>
<p>The first end of the box represents the 25th quartile. The second end of the box is the 75th quartile.</p>
<p>To find range you subtract min from max.</p>
<p>So you only look at the two endpoints not the end of the box.</p>
<p>I also remember a sinx=cosx problem. Can someone else confirm?</p>
<p>The expo problem: Not sure what the actual question was but x was raised and asked for x.</p>
<p>@aznboy1996 the box’s are the percentiles (25,50,75). The entire line segment (both top side and lower side) represent the entire range. It was 13</p>
