September ACT Math Discussion

<p>does anyone remember the wording of the problem involving the a+bi and the sqrt(a^2+b^2) ? If so, can you explain the solution? </p>

<p>P.S. i played roulette with this one and picked 2i I believe (which I know to be false now)</p>

<p>Its the only math I had trouble with, but it’s stumping me</p>

<p>so…what was the answer to the trapezoid problem?</p>

<p>Parallel lines allow you to draw congruent triangles of width 1.5 along the trapezoidal height.</p>

<p>Add the new length in both directions to the previous base’s measure to get 13</p>

<p>for the imaginary numbers one, you had to plug the answers into the absolute value formula and realize that none of them had an ‘A’ term.</p>

<p>sqrt(0^2 + (-3)^2) would yeild 3, which was the biggest answer if plugged into the formula.</p>

<p>

</p>

<p>The one where it asked you to find the length of the segment connecting the midpoints of the two sides? You just do 1/2(base 1 + base 2). I think the two bases were 7 and 19, so the answer is 13.</p>

<p>how many of the last like 10 were A/F</p>

<p>I totally messed up my timing :(</p>

<p>The Math test was hard. At the last part, it was mostly covered by word problems and Trig. For some reason, they upgrade the test every year. I thought it could be easy, but it wasn’t. =(</p>

<p>Hey,</p>

<p>Do any of you remember whether there was a sine law problem on the act sep. Math exam?if so, do you remember anything about it?</p>

<p>there was a law of sines… i cant remember the answer. it was something like sinD*F/sinF</p>

<p>What SAT score does Ivy schools looking for?</p>

<p>what was the trapezoid question?</p>

<p>and why is the answer to that one question with all the lines a circle?</p>

<p>Wrong thread… This is from a year ago.</p>

<p>oh my b
thanks</p>
