<p>wait... for the question for the sqrx sqry = 10.... the answer coould be 50 right? like root of 25 + root of 25.... it didn't say they were distinct numbers right? or did it?</p>
<p>ah yes now i remember. thanks</p>
<p>Was 1/9 the answer to #20 on the first math section? (Dealt with the skidding of speeding cars when they brake)</p>
<p>Does anyone remember the answer for the parabola question with the positive constant p?</p>
<p>For the answers Fed04 gave, what was the questions to answers that were 12 and 8?</p>
<p>i think its -4 to the post by ryan</p>
<p>Ok guys, i think there were multiple tests. I mean, i have NO CLUE WHICH QUESTIONS YOU GUYS ARE TALKING ABOUT.</p>
<p>The 900 questions was </p>
<p>f(t) = 100t^2 + 50</p>
<p>Find differerence between f(5) and f(4).</p>
<p>K, guys, i took the SAT (jun 4) here in Canada and NONE of your questions appeared on my test ><....</p>
<p>ali thats ok, it seemed there were MANY versions. The CR thread had only one post about my sections.</p>
<p>.... can someone answer my question... </p>
<p>for the problem that was like (squareroot of x) + (squareroot of y) = 10</p>
<p>did x and y have to be distinct different numbers...?</p>
<p>It didn't say they had to be distinct.</p>
<p>yeah for fed04's grid in problems...which was the problem with answer 12...i think i remember putting 12 down but i jus wanna be sure...</p>
<p>also there was a question involving f(x) and g(x) and the answer i put was y = x/m - (b/m)</p>
<p>I'm gonna work #20 :P</p>
<p>The equation for the length of skidmark for a car braking at a certain speed (v) for the time t (or some other variable whose property I forgot) is v=2sqrt(100t). If one car braked for 5 seconds, and had a skidmark 3 times longer than a car that braked for 5k seconds, what is k?</p>
<p>2sqrt(500)=3(2sqrt500k)
(2sqrt(500))^2=(3<em>2sqrt500k))^2
(4</em>500)=(36*500k)
2000=18000k
(2000/18000)=k
1/9=k</p>
<p>um, right? :/</p>
<p>Yeah, I got the same thing for the g(x) problem, but I can't remember the one with 12.</p>
<p>Yes I got 1/9 for the skid mark.</p>
<p>And the open ended about pushing the button/flipping the switch to make a noise or whatever was 2 pushes of the button.</p>
<p>so that means that the answer could also have been 50 right?
...haha.. im juss making sure cuz i dont want any stupid mistakes
-_-</p>
<p>Yeah, 50, 58, or 82.</p>
<p>w00t.</p>
<p>thanks</p>
<p>everyone got the prob with the circles and a triangle in them?</p>
