<p>Anyone get 18 for that 3(x-y) problem?</p>

782

<p>Wait so what exactly is the answer to the last problem about the 3 planes and 3 lines?</p>

783

<p>@h3x3h3x it was definately 6</p>

784

<p>@brazbloke. It’s f(2) becuase when you have f(x)=g(x)(x-2)+4, having f(2) makes (2-2)=0 so g(x) cancels and all you have is f(x)=r so r=f(2).</p>

785

<p>What was the question about tan(x)=k/2. What’s sin(x)?</p>

<p>Anyone remember the exact question?
The answer?</p>

786

<p>it was something like if tan(x)=k/2 then what is sinx.
so imagine a triangle is made by the x axis and the point (2,k). the width is 2 the height is k. hypotenuse is c^2=2^2+k^2 so c=root(k^2 + 4) and so sinx is k/root(k^2+4)</p>

787

<p>Lets post predicted score and raw answers right:</p>

<p>Predicted: 800
Raw: 48 or 49</p>

788

<p>for me its a max of 46.75 two omit 1 confirm wrong</p>

789

<p>Predicted: 800
Raw: 49 or 50 </p>

<p>Don’t remember if I put f(x)=f(-x) or the other way around for the graph reflected across the y-axis. I wish the lit subject test were this easy. Alas…</p>

790

<p>^ shouldn’t it be the same regardless?</p>

791

<p>were f(x)=f(-x) and f(-x)=f(x) both answer choices?</p>

792

<p>Predicted: 750
Raw Score: 41 (5 omit + 3 wrong)
****… That won’t look good in my application… U of Chicago, Georgetown, Stanford, Princeton, JHU and Harvard will laugh at my scores =P Hopefully UC Berkeley and Michigan U are a bit more lenient hahahaha</p>

793

<p>I don’t specifically remember if they were separate choices, but I’m pretty sure I put down f(-x)=f(x), which contradicts what everyone else has written so far in this thread.</p>

794

<p>No, they won’t. That is a perfectly good score.</p>

795

<p>what would 2 omit, 5 wrong be?</p>

796

<p>greywolf, I’m 100% sure it is the same thing, because that’s what I put. I’m pretty sure there weren’t two opposite answer choices.</p>

797

<p>@GreyWolf: I thought that was the right answer…? Even functions (those symmetrical around y axis) do that (take cos x for example)</p>

798

<p>so which one was the vertical shift thing?</p>

799

<p>squigglysquid: probably around 730-750</p>

800

<p>Predicting: 790-800
Raw: 53-54</p>
