<p>ya congruent and i thought it was -1</p>
<p>Was one of the answers (-a, b)?</p>
<p>^ Yeah i had that as an answer</p>
<p>wait it wasnt a rectangle thought it was a square. </p>
<p>x+0 is the only one that cuts through the origin. ??</p>
<p>Was the probability quetion 1/4? i think it was 50/200 which was 1/4?</p>
<p>Anyone know that one where it gave you the “net” of a figure and we needed to find the surface area? I put like 14 somthing.</p>
<p>“@shahdin, I believe it was abs(f(x)) >= 2”</p>
<p>What question was that?</p>
<p>Yeah I think i put E. for the surface area but I guessed.</p>
<p>Is the vector on B? Can someone cofirm??</p>
<p>No, it was a rectangle. The coordinates were (0,0), (4,0), (4, 6), and (0,6) I think.</p>
<p>I got 50/200, or 1/4, too.</p>
<p>ok but what did you get for the vector? I had B it was suppose to be in quadrant 4 right.</p>
<p>Damn, I got the rectangle question wrong… and on top of omitting 6, I doubt I’ll get an 800. 
And what exactly was the vector problem anyway? The one with b minus a?</p>
<p>when you take the limit of a function you have to factor out the top and cancel if u can. the denominator canceled, so the limit exists</p>
<p>what were some of the difficult ones from 1 to 30 for you guys?</p>
<p>argh…what are the chances of 7skip and 2wrong being 790-800 -_-
if not, does anyone know what it might possibly be?</p>
<p>not likely lol</p>
<p>does anyone think 42 could be an 800 or will it be the average curve?</p>
<p>The Vector one was b-a, the arrow in the 4th quadrant choice B?</p>
<p>Undefeated:
Are you sure that the ball one was 3?
I remember that it was dropped from a height of 10 feet and it asked for how many times it needs to bounce so that its rebound height is less than 6 INCHES. 6 inches is approx 0.5 (i just googled that, didn’t remember conversions in test)feet. The first bounce up was 0.4h, and height dropped was 10ft right?
bounce 1 (rh=10ft)
bounce 2 (rh=4ft)
bounce 3 (rh=1.6ft)
bounce 4 (rh=0.64ft)
bounce 5 (rh=0.256ft)
How did you get 3?</p>
<p>i also got 5</p>
<p>bounce one was 4, the result of the first bounce it ws 4 not 5.</p>
<p>I thought the ball started at 10 ft, not after the first bounce.
I got 4 bounces.</p>
<p>It was 4. The first bounce isn’t 10 feet high, it’s 4 feet high.</p>
<p>what do you think my score will be then? i’m soo mad about my stupid mistakes…lol</p>
<p>I’m not sure why you guys are finding the vector problem hard… All you had to do was come up with example coordinates for vectors a and b (I think I used A(1,8) and B(2,4)). Then just subtract those: (1,-4).</p>
