<p>I made this. Obviously I am not a math god, so some/many may be wrong.</p>
<p>Discuss.</p>
<p>I sucked the polar equation too, so don’t worry, you aren’t the only one! haha.</p>
<p>But for</p>
<p>4b. The absolute minimum value is -8. It’s asking you to find f(0), because it’s not asking for the x-coordinate.</p>
<p>5b. You made an arithmetic mistake in your Euler’s method. -1 + (.25)(2) = -.5, not -1.5 Yeah, that’s it though. Then follow through with Euler’s! haha.</p>
<p>All 6c is asking for is to plug in (2x) for every value of x and then take 2^nth power. After you do that, you must integrate the first 3 terms for the third power to find the “h”.</p>
<p>I still can’t do polar!</p>
<p>I disagree with 1D because you forgot to add in the initial 500 tons of unprocessed gravel. 135 is what I got at first too, but then if you read closely it says that initially there are 500 tons, so 135 is an illogical answer. I got 635 for that (135 + 500).</p>
<p>You guys are right with everything you said! I just rushed through this “key” so there should be mistakes that I did not make on the actual exam :)</p>
