ACT June 2010 - Math

<p>For the rhombus question I remember the radius being 6? I did pythagorean and got that the length of the the rhombus side was six too.</p>

<p>Oh and for the f of g of x problem you need to do</p>

<p>(x-1)^2 -1 =0</p>

<p>Getting 0 and -2</p>

<p>The rhombus one was 4</p>

<p>For the absolute value one, the answer was b, but I’m not sure what it said. Also, fr the a and b one (a+b)^2=a^2+b^2, it’s either a or b is equal to zero. And for the x in terms of w and perimeter, x = P/2 - 2w.</p>

<p>never mind… i just saw that other post</p>

<p>Ivysaur, I got the same answers there. I dont’ recall the absolute value one, though.</p>

<p>Do you guys remember 14,000 as an answer? Maybe it was in science.</p>

<p>it was like… 1-x< B and x-1> B or something.</p>

<p>@New account, that was in math, and I remember getting that for the shaded graph. I actually used calc lol.</p>

<p>@NewAccount yes i do.</p>

<p>For the absolute value one, the answer was b, but I’m not sure what it said. Also, fr the a and b one (a+b)^2=a^2+b^2, it’s either a or b is equal to zero. And for the x in terms of w and perimeter, x = P/2 - 2w. </p>

<p>the letter choice to the “either a or b is equal to zero” was A, not B. And yes that was the answer. 14000 was also one of the ansewrs along with what IVYSAUR said in post #68.</p>

<p>when and how do we get scores back?</p>

<p>Exactly 2 weeks time. As long as you have an ACT account, they will come out at 12 central, and you can just check them online.</p>

<p>What about the one on standard deviation? </p>

<p>I got 115. </p>

<p>And the last three were F,A,F right?</p>

<p>Help! I forget the exact question, but I remember the answers…they were along the lines of (-a,-b,); (-a,b); (a,-b); (b,a); (-b,a)…</p>

<p>Does anybody remember the question/correct answer?</p>

<p>abs(x-1) < B</p>

<h2>x-1 < +/- B</h2>

<h2>x-1 < B</h2>

<p>x-1 < -B
-(x-1) > B
-x + 1 > B
1 - x > B</p>

<p>Answers: x-1 < B and 1 - x > B</p>

<p>I don’t know if I did that right…</p>

<p>@xavier110 I got (-a,b) for that one.</p>

<p>(-a,-b,); (-a,b); (a,-b); (b,a); (-b,a)…</p>

<p>point (a,b) symmetrical over the y-axis? I don’t really remember…</p>

<p>so it would be (-a,b)</p>

<p>i was confused about the one that talked about a curve symmetrical to the y axis and (a,b) being on that curve. was it (-a, b) ?</p>

<p>EDIT: okay nevermind, i didn’t see those posts. my b!</p>

<p>@rivaldestiny That’s right</p>
