<p>I used law of sines twice- first for the 39 angle and then the 27 angle, getting the distance of the cities to be about 5 or 6 something after subtracting</p>

11.8.... I actually had time to take the derivative and check lol

Crosscurrent, do you still remember how you solved this? I graphed it, and the max value looked like 10.4 .</p>

103

<p>bpatel, just subtract from 270, and the answer is 239...</p>

104

<p>anyone else with any question? this is tearing me apart ....</p>

105

<p>Indian: "no nervous, the cities one was 5.8 something, and the rectangles one was 21.02"
wat is the 'rectangles' question? refresh my memory</p>

106

<p>lol when are the scores coming out?</p>

107

<p>did anyone remember....</p>

<p>"prime number divides 469 = remainder 5, wat is the remainder when the prime number divides by 50"</p>

<p>number 50</p>

<p>the one where "2n/6 = interger"</p>

108

<p>What'd you get for the one that asked:</p>

<p>If these two lines are parallel, what would be the value of nm?</p>

<p>y = mx - 1
y = nx + 3</p>

<p>There was m² and n² as an answer. Aren't they both the same?</p>

109

<p>I think that question was asking about perpendicular lines, in which case the answer would be -1.</p>

110

<p>Yeah, that one was about perpendicular lines, m1*m2 = -1.</p>

<p>"the one where "2n/6 = interger""
I got 2n/3 would also be an integer.</p>

111

<p>^^ yea thats wat i got... but im doubting it</p>

112

<p>I chose a number and did that, and 2n/3 was the only one that worked.</p>

113

<p>or you could have plugged it in the calc and went to solver....</p>

114

<p>i think the prime number was 21, or choice D</p>

115

<p>the answer was 21 for the remainder cause the number being asked to divide was 29...</p>

116

<p>^^i got that as well...but i guess :-( i had no idea how to do that</p>

117

<p>How about the k log5(5) - k log5(25)?
I put 1/5 for that, but I wasn't sure if the k is just removed or not?</p>

118

<p>FYI: My friend skipped 8 on the Nov test and still got 800</p>

119

<p>did anyone eles get like a row of c's in the middle of the second column?</p>

120

<p>log5(5)=1, and log5(25)=2, so i got k-2k= -k</p>
