<p>i cant believe so many people put 16 for that 11.... LOL</p>
<p>^I can't believe it either Ren.</p>
<p>so whats ur prediction of ur scores shio?</p>
<p>For the graph asking for the points where f(x)=b, did the graph cross b at the y-axis?</p>
<p>hmm... yeah, 3 times.... at b</p>
<p>For some reason, I thought that the graph crossed the y-axis at b so I marked 4. At least, I'm sure that not counting the y-axis point, y(x)=b 3 times.</p>
<p>if u draw a line horizontally...u see it's 3 times~~</p>
<p>here's a list of correct answers so far (please do not post any more wrong answers)
9. 11 (teams with 2 or more ppl)
10. 120 (area of rectangle?)
11. 128
12. 3.2 (a+b)
13. 45 (one of the possible scores he could've gotten)
14. 1/25 (1/a^n)
15. 8
16. 3 (how many areas does f(x)=b)
17. 2200 (number set)
18. 34 (Weird symbol one)</p>
<p>In additon we have:</p>
<ol>
<li>(17/2),</li>
<li>abs value of x-32<2,</li>
<li>.5<x<.25</li>
<li>15</li>
<li>b=k (Someone posted this. I remembered there is one ak/b=1)</li>
<li>18sqrt3-6pi (this is definitely true)
( not in any particular order)</li>
<li>the dotted thingy was 10 pi</li>
<li>the roman numeral question was none</li>
<li>k=-3 (D some people said)</li>
<li>x^3+X (-f(x)=f(-x))</li>
<li>the y>x graph, it was D, the exponential graph in quad 2</li>
<li>10 pi ( 5 dotted semi circles)</li>
<li>elevator , 3 stops, 80 ft</li>
<li>3 circles , forming trapezoid is 20</li>
<li>trapezoid,asking for rectangular perimeter is 22.</li>
<li>the sequence was 2^n (n=1, 2^1=2)(n=2;2^2=4)(n=3;2^3=8)</li>
</ol>
<p>All of these are correct. Add to the list and pass it on! ! ! !</p>
<p>Please read why I think the trapezoid with three circles is wrong.</p>
<p>I get where you are coming by. I just can't recall where the third circle was nbafan135. 20 makes sense but it seems to be too obvious. </p>
<p>I drew a perpendicular bisector from the top of the trapezoid to the base of the trapezoid. This formed a right triangle. Next the two radii willl form an equilateral triangle, 60, 60, 60. Therefore the 30-60-90 forms due to the perpindicular bisector. 30-60-90 would make a 2, 2root3 and 4 triangle (leg, leg, and hypotenuse respectively). Ok with that said, the leg 2 root 3 is part of the rectangle (in between the two triangles). Rectangles form a 45-45-90 triangle when a diagnol is employed. Therefore the top portion would be 2 root 3 and the final answer would be 4+4+4+4+2 root 3 which equal 16+2root 3 (~19.46)</p>
<p>^ Where on the trapezoid did you draw the perpendicular bisector from? One of the top 2 vertices?</p>
<p>you can divide the trapezoid into three triangles. you know that the lower two triangles are equilateral because each side is equal to the radius of a circle. each inner angle = 60 degrees, trapezoid's on a straight line, so the lower angle of the middle triangle is 60. you can then figure out that it is equilateral because you also know that two sides of it are both equal to the radius of the circle (2x + 60 = 180). then, the top portion would equal the radius. 4*5 = 20.</p>
<p>for the one with the perimeter of the quadrilateral in the circles, for some reason remember putting 30 when I definitely know that makes no sense. Was that one of the choices and I made a completely ****ed up arithmetic mistake or am I just imagining things?</p>
<p>for 1/25, since it was a fill-in is .04 also acceptable?</p>
<p>yes, as long as it is equal to 1/25, its acceptable.
2/50 would be correct, even though I doubt anyone put that o_o</p>
<p>@ThisCouldBeHeavn - Yes, they accept both decimal and fraction answers.</p>
<p>Yes .04 would be acceptable.</p>
<p>^Are the questions 1-16 the entire 20 minute math section? Or spread out answers between the MC of the 18-Q, 20-Q and 16-Q sections?</p>
<p>Can someone please refresh me on the questions of the number 18 grid-in and the number 16 of the MC we have? I forget those problems, but the 34 looks familiar.</p>
<p>what was the 8 answer in the grid in section, please refresh my memory!!!!</p>
<p>Yes it was.</p>
<p>You guys are so lazy. scroll up, there is a consolidated answer post -_-</p>
