<p>Yah the answer was proved a few times on this thread.</p>
<p>for the vector one… was it a-b or b-a??</p>
<p>^ It was b-a, I’m positive</p>
<p>b-a for sureee</p>
<p>and its basic physics…flip a and put it tip to tail with b
resultant vector ends up in 4th quadrant</p>
<p>either way it would have been the same answer, lol</p>
<p>^ no it wouldnt, a-b would be in 2nd quad i think</p>
<p>ah, good point, my bad.</p>
<p>when i said that i was misremembering the question… at least i had the right answer</p>
<p>I’m loving this thread so far. Sooo many of the ones I guessed on I’m getting correct.</p>
<p>ok wait so wan to clarify two things. for the mean one it is 1 only right which states that mean=median. also what is the consensus on the one with the long equation and we have to talk about the discontinuities.?thanks</p>
<p>ahah im not =P</p>
<p>for the trough, did anyone get 1.125sin(theta)? (based on .5absinC)</p>
<p>for those of you who don’t want to read 13 pgs of posts…</p>
<p>-first one was like 31892
-total 4 three digit numbers was 24
-determinant was 0
-range was greater than .794?i think
-y-3=cos(2(x+5))
-the one with symmetry to origin had graphs resembling tan x
-for the one with the volume of the trough i think i put 18sintheta
-ax2+bx+c one was a i think
-the one with the 840 beach house vacation was $140
-#50 was 2log(cos(x))
-vector one was 4th quadrant
-the one with the rectangle and line x+c was -1
-the one with 1/a+1/3a+1/2aetc… was 11
-the one with like smallest angle of a triangle was 44 (all from sixhsense)
-for the m^90 one it was 34
-the limit was 2
-the SA of the prism was 156.7</p>
<p>that’s all i remember</p>
<p>is it rounded up or down? -2 2 omit -> -4 or -5?</p>
<p>it was 18sintheta</p>
<p>to upton,
no. its (0.5 absin(C))*16</p>
<p>oh, true, forgot about length.</p>
<p>was 2 log(cos(theta)) choice c? that’s what i put… i remember filling it in at the last second. i compared graphs on my calc.</p>
<p>So far I’m looking at 5 wrong 5 omit. Meh not bad for not studying at all.</p>
<p>so far i’m looking at 1 wrong and 2 omit. okay for not studying but i thought it would breeze thru this =[</p>
<p>ouch man…you forgot to multiply by 16 (the height)</p>
<p>and the matrix question…
you can put it in your calculator and use rref; this is show that the three planes intersect on a line so there are infinite solutions -> singular -> det=0</p>
<p>and i dont remember what this question was asking but…
f(x)= x(x+2)(x-2) / (x-2)
…if its the discontinuity question, its at x=2</p>
