<p>Yes, exactly. I remember there were just 2 answers where x=/=0 and the other one was absurd, so yeah.</p>
<p>i think the question with (2-i) as answer just gave 3 (or was it -3, not sure) and 2+i as roots, and since imaginary roots always come in pairs you know 2-i is root as well, but you don’t know that both ±3 are roots.</p>
<p>@Marie do you remember if you picked C for that question? I remember it being C?</p>
<p>Yeah, I think it was C.</p>
<p>and Extelleron: exactly! Same logic here.</p>
<p>^ omg, i had 2-i and decided and erase to ommit the question ■■■ lmao. ( I used the same logic as u guyz but thought my logic made no sense lol).</p>
<p>I’m screwed, I originally thought I did well and now know I missed 4 and omitted 2. ****ing perfect.</p>
<p>marie: i mean C for the lxl question right? lol sorry just getting a bit anxioius.</p>
<p>hahahah i feel great…all the ones that i skipped i shouldn’t have b/c apparently i had the right answers.
now for the ones that i guessed…hmmmm got em wrong!
okay that triangle prism one WAS weird. I used the pythagorean ttheorem and got square root of 33 for the height of the middle rectangle, but i STILL didn’t get an answer that matched teh choices!!:(</p>
<p>would -8 be a reasonable curve for this test?</p>
<p>marie: i mean C for the lxl question right? lol sorry just getting a bit anxioius.</p>
<p>Guys, is it just me or was this particular test insanely hard to finish in time? </p>
<p>I mean I finished the BB practice tests in ~55 minutes but I had to skip 7 questions today.</p>
<p>Yeah.</p>
<p>The prism one got me. I think I misunderstood the question or something, because the answer I kept getting was different from the answers given. So I skipped in the end.</p>
<p>Weren’t they asking surface area? there was…what…7x8+7x8+7x4+4x2 or something? Well, I remember getting 172 in the end. O.o</p>
<p>@MARIEM</p>
<p>No it is not 6a^ 6</p>
<p>if x^5y = 2a
x^ 30y = 2^6 a^6…
not 6a^6…</p>
<p>and scimmy boy it was ASKING FOR IS IT TRUE FOR SOME VALUES
IT WASNT ABSOULTE</p>
<p>ALSO
for the sin and cos x </p>
<p>it was true for II and III</p>
<p>and For imaginary number i think the root was 2-i?</p>
<p>then the other root has to be 2+i… the number in the front stays the same
u just need to flip flop the sign on the imaginary number</p>
<p>private message me if you need help
i think this test was easy because there was no tricy problem about probability</p>
<p>@lucky it was choice C for that y, 2a question. I plugged numbers etc.</p>
<p>For the sin(x)+cos(x) one, I chose II and III. I graphed it, and also used solve() on my calculator. I’m 100% sure I’m right.</p>
<p>For the 2+i question, I put that the only one you must have is 2-i because in complex conjugates (the coefficients are all real), they come in pairs.</p>
<p>For the “what is x^30y equal to when x^5y=2a”, here’s how it works:</p>
<p>x^(30y) = (x^(5y))^6 = (2a)^6 = 64a^6.</p>
<p>So far, I omitted 2 or 3 and got 0 or 1 wrong. This is my second time taking it, so I managed my time well and finished with 5 minutes to spare, as opposed to last time, which was horrible…</p>
<p>^ Presidont yeah I also had that do you rmember it being choice C? for the 64a6</p>
<p>I just plugged in values.</p>
<p>so ^ Presidont and shahdin we all agree on these three questions!</p>
<p>right?</p>
<p>I ommited the 2-i but yeah it was 2-i</p>
<p>I had 64a6 Choice C? you guys remember picking choice C?</p>
<p>I had II and III.</p>
<p>also had abs(x) greater than or equal 2 except 0 (Also choice remember picking choice C)</p>
<p>The quadrant one has been cofirmed to be quadrant 4downwards (It was Choice B.)</p>
<p>for the sinx+cosx one</p>
<p>doesn’t II and III means that whatever the equation is, it will ALWAYS equal 2?
Because you can’t just plug in one integer for x.</p>
<p>sin^2x+2cos^2x =2</p>
<p>When an equation is presented to you like that, you’re saying that both sides must be equal for any x at all.</p>
<p>I still think the answer is none because of that.</p>
