<p>Yeah… I skipped ten. But there were a couple of easy questions (as opposed to my practice tests - btw, math is my worst subject). I’m hoping for 650+, but I don’t need anything higher than that.</p>
<p>I think the general consensus is that it never said the numbers are replaced, but I don’t think it ever said that they are not replaced, so that’s an ambiguous one.</p>
<p>but it said that the second even number had to be different from the first even number</p>
<p>edit: ok posted too fast without reading previous posts…</p>
<p>The cos(x) problem was -3/5. All you had to use was inverse functions.</p>
<p>the last question was 1 second
cuz 2.5-1.5 = 1</p>
<p>was the last question choice B? thats what i remember putting</p>
<p>no cos(x) problem was -4/5
im 100% sure</p>
<p>Hoptkins, thats what i put, i think, -3/5… but i dont remember what the angle looked like anymore… </p>
<p>i might’ve put -4/5… was the 4 part on the x-axis?</p>
<p>For the question about the line and 2 unit thing, was it a cylinder that extends infinitely?</p>
<p>thats what i put immortalix</p>
<p>when to scores come out?</p>
<p>i don’t remember the -3/5, 4/5 one but i do remember putting 3/5. why would it be negative? i don’t remember it showing an axis at all…</p>
<p>i would assume for the probability one that if it didn’t say it was replaced it wasn’t…but that’s just me.</p>
<p>on the f(100) one it said f(10)=0 and if 100 is a multiple of 10 wouldn’t it just be 0 then?</p>
<p>i got an infinite cylinder yes.</p>
<p>does anyone remember the answer to the inverse function f(2e)? i think i put c but i don’t remember the actual answer.</p>
<p>are you sure the last question was 1s and not 2.5s? i thought it asked how long to hit the ground?</p>
<p>Awkturtle, it ran on a cycle of 7 though, not 10. So it came out to be 1.</p>
<p>scores come out on the 21st i think</p>
<p>It was how long 'til it hits 20m after it reaches the max I think.</p>
<p>Reached max at 1.5s and 20m at 2.5s.</p>
<p>the one with the parallelogram, with 2 sides and a angle, was the solution 6? I did that with measuring but i think it might not have been to scale</p>
<p>what score am i looking at with two wrong and four omit? 50-(6)-(2*.25)=43.5–>44 raw score…</p>
<p>uggghhhhhhhhhhhhhhh im so maaaaaaaaddddddd… i was aiming for an 800 and i already know of 3 i missed… plus i skipped one. then i probably missed like 5 more. -.-</p>
<p>for the f(100) one, f(10) == f(100) because it cycles every 7 units, not every 10 units. So, f(7) = f(14) = f(7k) = 0. </p>
<p>f(100) = f(7(14) + 2) which is equivalent to f(7k + 2). Thus, f(2, 9, 16, 23… 100) all have the same value, which is 1.</p>
<p>I put infinite cylinder.</p>
<p>For triangle, here’s the simple logic I did:</p>
<p>siny = 4/5
y = sin inverse 4/5 = 53 degrees. x is equal to 90 + 53 = 143. I’m sure cos(143) is indisputable.</p>
