<p>for the data table table with increases of millions
was the scatterplot just a line or a curve?</p>
<p>also what was the answer for the problem like which value of y makes the line perpendicular to the other line?</p>
<p>Graphs that are increasing at an increasing rate tend not to be linear.</p>
<p>I left 4 questions and got 5 wrong. Will that scale a score of about 750?</p>
<p>For the question that gave the graph of the terminal side of an angle and then asked for the secant. This is what I did:</p>
<p>y + 5x = 0</p>
<p>y/x = -5 = tan(x)</p>
<p>tan^2(x) = 25</p>
<p>sec^2(x) = tan^2(x )+ 1</p>
<p>sec^2(x) = 25 + 1 = 26</p>
<p>sec(x) = sqrt(26)</p>
<p>Answer = -sqrt(26) [secant is negative in the second quadrant]</p>
<p>Can anyone confirm this?</p>
<p>@doodlecat That’s what I did as well. This question was just annoying because the answer seemed too obvious and therefore made me nervous that I’m missing something.</p>
<p>This is what comes up when you enter the inequality into Wolfram: </p>
<p>Alternate Form: False
Difference: Zero</p>
<p>This should mean no real numbers (E), right…?</p>
<p><a href=“-y(abs(y)) < -y(abs(-y)) - Wolfram|Alpha”>-y(abs(y)) < -y(abs(-y)) - Wolfram|Alpha;
<p>@rafaelesf yep, i think so! i spent too much time looking at those too-simple ones and had to omit so many questions </3 </p>
<p>For people who want to know if they scored at or above a 750. In october I scored a 760 and did not answer 9 and probably got 1 or 2 wrong.</p>
<p>In order to score 750, at a curve of 44 = 800, you’d have to lose 11 points: 11 missed, 3 wrong : 7 missed … 7 wrong : 2 missed etc. But in the end it all depends on the curve.</p>
<p>sorry i meant -y|y| < y|-y| for the absolute value question …
shouldnt it be all real numbers??</p>
<p>I got no real numbers. But yeah, it seemed too obvious. </p>
<p>For the question about x+w=y+z or what ever the answer was, what was the question number for that question? </p>
<p>Someone please respond to this because i may have skipped a question and filled in the answer to another question into the space for the skipped question and so on. Then i’d be screwed haha</p>
<p>^it was #49</p>
<p>I don’t think it could have been 49. IIRC the last two questions were something about a secant of an angle in the second quadrant and a ship between radars respectively.</p>
<p>Definitely not 49</p>
<p>And I really don’t think anyone is going to remember something like that… Just move on and take another test if you need to. </p>
<p>im a senior and got 770 first time as a junior and then 770 again last october cuz i got really sick and now i need a 800
i think it was number 19. anyone agree?</p>
<p>Also, did anyone chose only 1/x as the answer to the qeustion about which inverse function is the same function as its original function.</p>
<p>@gkdld3131 the answer was 1/x and 1/(x-1) (±) 1 sorry dont remember what sign it was but ya it was I and
III i believe</p>
<p>I’m pretty sure it was 25 on the rows chairs question. And for period of 8 I got 15.</p>
