<p>what was the answer to the question like if f(g)=f(x+2) then what is the x coordinate for f of g the answers were -4, -2, 0, 2, 4… guessed -2, really don’t know, neeed help</p>

<p>By the way I got two “not enough information” answers which struck me as really odd. I think one was experimental, but did anyone else get at least one</p>

<p>One of the ones I put not enough info for was the triangle one because the angles were all different (I think that I made the missing angle 80 instead of 70 which is actually a pretty common mistake for me).</p>

<p>It was 70… Isosceles</p>

<p>bumpppppppp</p>

<p>Can someone tell me which math is experimental? Is the ice cream cone one experimental</p>

<p>can someone post the ceaser salad question on here. i dont remember the numbers but want to see if i got it</p>

<p>the ceaser salad question is experimental though because some of us did not have it right?</p>

<p>If a and b are both negative, then ab is positive. Since the square root symbol refers to the positive square root, then, sqrt(ab) will not equal (a+b)/2. The only situation when both the negative and positive square root of a number is used is when the problem is asking a variable squared equals a number. Since (a+b)/2 is negative, and the sqrt(ab) refers to the positive square root, then a cannot be less than 0. For example, if we say a=-1, then b=-1. (-1)(-1)=1, and the sqrt(1)=1. However, (-1±1)/2=-1.</p>

<p>Did the caesar salad question provide a table that shows different dressings and salads? If so, then that was not experimental, because I received that question, and my experimental was writing.</p>

<p>ok. so, do you remember the numbers?</p>

<p>can anyone at least give me the answer choices for that one.
Weren’t some choices 77 and 79</p>

<p>I’m really hoping that the curve is generous… I’m pretty positive I got at least 4 wrong, maybe 5. I got a 690 last time with 5 wrong, so here’s hoping I can improve!</p>

<p>Anyone remember the answer choices for the stacked cup question? I know I put D, but I’m not sure if that was 48 or not. The consensus on these forums seems to be that 48 is the correct answer.</p>

<p>^@epicdude, I would imagine it would be more generous. I took it in January and got about the same score on math as you. If you got the same number of questions wrong as last time, you would only be gaining 20-30 points probably though. Hopefully you end up missing less!</p>

<p>Same Sumin, I put C but I’m not sure what the actual answer for C was…</p>

<p>I kept doing 10 + 20(2) instead of 10 + 19(2) and I realize how dumb I am for counting the first cup too… >_></p>

<p>Hopefully, to be honest 20-30 points would be fine with me! I also had a math experimental, but I’m not sure which one it was or how it will come into play with my score… I’ve got my fingers crossed!</p>

<p>There was this one question with an upward facing parabola with vertex (c,d). Then it asks something about a line or something, and I think they meant the horizontal line of y=d. So I chose the answer that looked like (-5,d) because the x-coordinate of that line could be any number. Is this what you got?</p>

<p>For the salad question, I believe the answer was 80.</p>

<p>To solve the “can’t divide by zero question.”</p>

<p>y=(x^2)/(x) is not the same as y=(x)</p>

<p>(y^2)=x is not the same as y=sqr(x)</p>

<p>If the original, unsimplified version is the true , then the equation holds true.</p>

<p>Ughhhhh. Did the cost with the greatest discrepancy between A and B also happen to be the greatest cost in A overall? I think I misread the airplane one and chose the greatest cost in A.</p>
