<p>Yeah, they completely threw me off with the "inclusive" claim. Does it not include the limits of the range (100 and 110)?</p>

82

<p>no im talking about the problem with slope m and the shaded region. I put zero because slope of -1 includes that region and that sum equals 0</p>

83

<p>The slope is between 1 and 2.</p>

84

<p>i thought it said though that a-b^n = a+b^n for ALL values of (a+b)</p>

<p>then it would be 11. bu ti must have read it wrong. AT LEAST its only a grid-in so theres no extra penalty. im just hoping for above 700..</p>

85

<p>(a-b)^n=(b-a)^n </p>

<p>ok but isnt (a-b)=(b-a)? If they are raised to the same power doesnt a-b and b-a inherently have to be the same number?</p>

<p>so if they are...
a-b=b-a
2a=2b
a=b</p>

<p>So if they are the same, then a-b and b-a equal zero. Zero to any power is zero. so all of them work?</p>

86

<p>Hi guys - saw this asked I think but the one where x^5=sqrt(y), the answer was 1/4, I agree, but I'm wondering -- 1/4 was the first choice (A) right? They went in order</p>

<p>1/4</p>

<p>1/2</p>

<p>1</p>

<p>3/2</p>

<p>2</p>

<p>Correct...? :)</p>

87

<p>1/4 for sure..
i found this november math really easy</p>

88

<p>me 2 really ezmod</p>

89

<p>yea 1/9 ths wht i got</p>

90

<p>was this in the experimental section? </p>

<p>a figure of 2 right triangles that have bases on the same line and have the same height (8), but one's base is 8 and the other's base is a lot longer..they want you to find length JK (part of the height of the smaller triangle)....it was the last problem in one of the math sections (not grid-in)</p>

91

<p>can someone please explain why the shaded slop m question couldn't have a sum of 0. I realize the slope was 1 but the other line could have had a slope of -x. thus -1 + 1 = 0</p>

92

<p>jcy2009 is making a lot of sense...thats what i thought when i was reading it too. idk guys haha. it might be 11.</p>

93

<p>is it okalahoma?</p>

94

<p>u can basically put a = b to the ^n and try each number i had 10 mins left over so i did and i got 6 guys</p>

95

<p>Oklahoma was the answer.</p>

96

<p>yea oaklahoma</p>

97

<p>yes.........</p>

98

<p>my fr answers:</p>

<p>60
1000
1/9
130
7/16
4
94
10
1.5
6</p>

<p>agree...disagree?</p>

99

<p>So the last math question was x+3 (choice A)?
and rad 2. so the last two were A. thats what I got and I thought it was wrong haha.</p>

100

<p>uhm im pretty sure it was montana. maybe i read the question wrong.</p>
