<p>Thanks Chris :D</p>
<p>Maximum value for quadratic function was B, sorry. It was -2 squared, which is larger than just +2</p>
<p>@confused, 20 sadly does not work.</p>
<p>WIll you explain the pen/pencil one?</p>
<p>@good scores
i still disagree with m = 2k</p>
<p>^thats what I put, idk if I’m right.
what about the g(-1)?</p>
<p>goodscores is right.</p>
<p>why was the pen question 1.6 and not 1.4?</p>
<p>@Skorpius7: No, it was… C?</p>
<p>@confused93: 20 doesn’t work.</p>
<p>Kevin, it says (a^2)^k = a^m. Unless you change the rules of mathematics, there is no way to disagree =P</p>
<p>The pen question is 1.6. You can solve it in two ways. The easiest is to realize that since each person holds 3 objects, if one avg is 1.4, the other has to be 3-1.4, or 1.6. The other way of doing it is through averages, which is a bit trickier to explain over the internet. </p>
<p>PS - sorry if I am sounding cocky, but I am sure my answers are right</p>
<p>I haven’t sen anyone ask this question, which makes me think it may have been an experimental.</p>
<p>It was something like:</p>
<p>If b (less than or equal to) 3 when a^2>9, what could be a value of b when a=3?</p>
<p>Also, the answer to the polynomial one that was graphed on and asked about it being reflected across the x axis? I think I put like (5,-6)</p>
<p>20 works fine…
it removes 20, 40, 80, 100</p>
<p>@kevinsupreme there should only be one x, not two, for the 6,8,10 triangle</p>
<p>with your answer, 2, if you plug it back in you get 10=2+(8-2)+(6-2) which is incorrect
for 4, you get 10=4+(8-4)+(6-4) which is right</p>
<p>so how do you go from a^2^k = a^m to m=2k
the “^” acts as an exponent and i don’t see how you bought the k down from the exponent</p>
<p>Wait… so 20 works or not? Can someone explain please? :o</p>
<p>The one with the between what months is the height of something 20 I think it was 6 - 8 months? IDR the answer.</p>
<p>The parabola was the one facing upwards 100%</p>
<p>@wannabe good call
damn it…</p>
<p>KevinSupreme, you end up getting a^2k=a^m which would mean 2k=m</p>
<p>Kevin, when you use “powers of powers” as teachers call it, you multiply the two exponents together. It is a rule of using exponents. [Exponents:</a> Basic Rules](<a href=“http://www.purplemath.com/modules/exponent.htm]Exponents:”>The Basic Ins and Outs of Exponents | Purplemath)</p>
<p>And actually, 20 does work. Very nice job confused. The answer had to wipe out 4 extra numbers under 100, and 20 does that because 60 is already a multiple of 3.</p>
<p>@ kevinsupreme
it is just simple exponent properties, (a^2)^k simplifies down to a^2k
so a^2k=a^m thus 2k=m</p>
<p>20 does work because 1, 3, 6, 9,…99 is a total of 33 numbers, which includes 60, so if going by 20, you add to the list, 20, 40, 80, and 100, which is a total of 37 numbers which is 63…so get tossed all you guys who said 20 doesn’t work</p>
