<p>Omitting around 5-6 gets you an 800</p>
<p>also, the range of all real numbers was x+5, correct? </p>
<p>@coffee100 yes </p>
<p>@coffee100 which question was this?</p>
<p>@AkPenn it asked which functions had a range of all reals</p>
<p>and i’m super sure that y/x = n^2 i spent like 6/7 minutes on that question.
x is an integer squared and n is an integer. so say x=81 and n=5.</p>
<p>y/81=25 ----> y=2025 (which is 45^2)
try it with any number. it works</p>
<p>And there was a question Sin(2x) = a . And we had to find 2sinx. I got 2a as the answer</p>
<p>What was the question with 65 as an answer?
@phlips that’s what i put</p>
<p>@phlips That’s correct but you could’ve just realized that since y and x are both perfect sqaures (y/x)^2 = n^2, and so y/x = an interger. </p>
<p>@SameerHussain Sin(2x) = a is the same thing as 2sin(x)cos(x) = a so to find 2sin(x) divide both sides by cos(x). You get 2sin(x) = a/cos(x) which is the same thing as sec(x)a so the answer is sec(x)a - not 2a</p>
<p>did people get these answers:
for the question asking about the nature of x value the x value was imaginary
for the question with 8 and 3 only points, the only solution was “a score can be even or odd”
with the three trig functions and graph, the first two matched the picture (I and II only)
3^11 (i think this was wrong)
the range of the set of numbers was 7
f(x)= absf(x) for x^2
for the sin(2x) problem the answer was a?</p>
<p>@coffee100, for the sin(2x) question, I got the answer to be 2a.</p>
<p>what did you guys get for that one probability problem that was like 11 people and 3 different lineups? I don’t think I read the question carefully enough but I thought that the answer was supposed to be some form of 11<em>10</em>9 but I didn’t see that anywhere. maybe it wasn’t but I probably got it wrong anyways lol</p>
<p>@blueray47 it’s just a combination (11 choose 3), which is just 11!/(3!•8!).</p>
<p>what is the answer to the one that’s about mean to the deviation or something like that
and what’s the answer to the one with a very complex funciton "xy^5-something=xy…</p>
<p>What was the where n^box n=n(n-1)(n+1) what does 3^box/8^box equal. I think this is what the question was. I put 1 </p>
<p>@Ayeplshelp yep, that’s right.</p>
<p>@phlips it was x+5 bc the other options did not have the range of all real numbers. </p>
<p>Can someone explain the sin theta and sin phi one to me? Just hoping for a high 750+ </p>
<p>@auditi5, the answer was π - theta.</p>
<p>Frick I put Pi/2 plus theta oh well</p>
