SAT May 2009 Math

<p>Just got back from the test!</p>

<p>Looks like I have all these correct, but on the way home I realized I make an incredibly stupid mistake on one of the easy questions x.x Still, I’ll be happy with -1 as long as it’s not 770 this time…</p>

<p>The girl took the test on tuesday, was physics.</p>

<p>Mode < mean <median</p>

<p>Quadratic- 12
Vertices- 1/5
Triangles with shaded part – 3pi
b-a = 9

101
3x=6- 17
f(x) > f(3)- 5
y^2 - 2y
mode < mean < median (70 < 75.5 < 80)
Sequence (100,2,100,4,100,6) - 0
Slope = -2/3</x<2></p>

<p>why does f(a)=f(b) have a slope of 0?</p>

<p>and would someone please
and could someone please explain how the are of the rectangle with the triangles on it can be solved?</p>

<p>There’s one of two triangles and 3x4 + 5 x 12 = 36 or something like this?</p>

<p>Lets see…The 100-2-100-4-100-6…etc problem was diff=0. </p>

<p>(They were both 100).</p>

<p>it is basically saying all y-values are equal; slope is change in y over change in x, no change = 0.</p>

<p>rectangle one: 10 x 30 = 300
each triangle had an area of 25; two triangles = 50
300 - 50 = 250.</p>

<p>if f of a = f b for all points that means they have the same values.</p>

<p>in fact ALL x values have the same y value. when that happens, slope=0. pm me for more clarification if u want.</p>

<p>Also there’s x delta Y = x^y + x, is it 2?</p>

<p>what is the 2x+by=3 and 2x+10y=5 problem? 5?</p>

<p>ok, I added everything… I think.</p>

<p>Does anyone know which section was the Math experimental?</p>

<p>Unanswered:
There’s one of two triangles and 3x4/2 + 5 x 12/2 = 36 or something like this?
Also there’s x delta Y = x^y + x, is it 2?
2x + by and 2x + 10y parallel, what’s b?</p>

<p>

</p>

<p>That’s the one I totally messed up… I was worrying about another problem and didn’t realize you had to solve for the base of the second triangle. x.x</p>

<p>It was Wednesday and Calculus not Physics on Tuesday.</p>

2x + by and 2x + 10y parallel b=10
Y = x^y + x (special function with delta sign) - 2
area of two triangles and 3x4/2 + 5 x 12/2 = 36</x<2></p>

<p>here’s what we have so far. DO NOT discuss anything already on that list. (unless you see a blaring error)</p>

<p>Ok the guy does not do calculus.</p>

<p>The other girl’s test was after physics</p>

<p>Therefore order should be.</p>

<p>Girl - Physics on tuesday
Other Girl - Calculus on Wednesday
Guy - English on thursday</p>

<p>Unless… I’m getting the names mixed up. Anyone else confirm that I mised that up?</p>

<p>I, too, had physics on tues but it’s probably wrong.</p>

<p>In addition to the confirmed answer list, please try to remember these:

<p>The answer is calculus on Wednesday. You are wrong. period.</p>

<p>@thequestionmark, you have the right procedure, just the wrong name.</p>
