<p>@Cbatarseh yes it was r. and since it asked for the y intercept, the answer is 0. can some of you post on the CR forum please? I need help on CR more than Math…</p>
<p>Crap… I’ll post in a sec!</p>
<p>Is the math curve really that harsh???</p>
<p>The angle question definately said add up to less than 180 not can be less than 180</p>
<p>Correct me if I’m wrong but I’m pretty sure the a+b/2 = sqrt(ab) was I II and III. if a and b = -2, it comes out to -2=sqrt(4) and -2 is a sqrt of 4 so I is good. If a and b are both 0 it comes to 0 = 0 so II is good. And obviously is they are both 2, it comes to 2 = sqrt(4) and works again for III.</p>
<p>Yeah the math curve is harsh. For this one, -1, 750, -2 would be maybe 690 maybe 700.</p>
<p>@ hittce
-2^2 = 4
sqrt(4), however, is only +2</p>
<p>@ Hittce - Yes, -2 is a square root of 4, but it is not the principle root of 4. Anything under a radical means you take the principle (positive) root.</p>
<p>i got I II and III too</p>
<p>Ok well I’m pretty sure they didn’t specify principle roots in the directions, in my opinion if y’all are correct that question should be thrown out because how are you supposed to know you just “throw out” one of the answers.</p>
<p>@hittce, how can a<0? The square root of a negative number is imaginary, so ofc it cant be I.</p>
<p>dragooner: if a and b are both -1</p>
<p>dragoon read my description again, if a and b are -2, -2*-2 under the radical is 4 so it takes the square root of four, not a negative number</p>
<p>If a=0, then cant I be true?</p>
<p>that question is ****ing me off</p>
<p>me too. i never learned about principle roots or whatever</p>
<p>I was a<0, however, a=0 satisfied II</p>
<p>I’m pretty skeptical with the whole principle root thing, I’m still convinced I was right on it, the square root of x^2 is + or - x</p>
<p>i hope youre right Hittce. im so frustrated about that one</p>
<p>@Hittce except the thing is that ((-4)+(-4))/2 is -4 which does NOT equal 4 from sqr(-4*-4). So, it can’t be choice I.</p>
<p>For anyone else, what have the math curves been like from March and May for 1 wrong?</p>
