<p>The vertical velocity though is not constant. At some points it would be moving more left to right than up and down I.E. near the very bottom and top</p>
<p>I think it was 2.3 because 74.4 was 2 standard deviations away from the norm.</p>
<p>shishdiddy the y axis is what matters the height, this isnt a velocity time graph</p>
<p>which of the set of triangles was obtuse? i put D</p>
<p>if it was a velocity time graph it would be a straight, horizontal line, which the graph im talking about wasnt. if the position time graph has straight lines that aren’t horizontal or curved, then that means the velocity time graph is a horizontal straight line…or velocity is constant</p>
<p>The obtuse one I think was 8 11 16</p>
<p>I thought the Statistics problem was extremely out of place. Don’t know why they included it.</p>
<p>for te obtuse triangles I got it down to d and e</p>
<p>I ultimately choose the 8,11, 16 one I think (if those are the numbers, wow it somehow just came to me) </p>
<p>b/c two short sides and a long side. Idk though, someone tell me what you get</p>
<p>CAN ANYONE CONFIRM THAT #54 was (K) mn???</p>
<p>I got 8,11, and 16 as well because it was the only one where a^2 + b^2< C^2</p>
<p>Yeah, I ultimately put 8, 11, 16. You could easily get rid of the two Pythagorean triples and the isosceles triangle, but then I kinda guessed. 8, 11, 16 seems reasonable, though.</p>
<p>It’s multiplied</p>
<p>the answer I think is mn</p>
<p>The maximum terms for the product is when like terms do not exist. The answer is mn because you distribute multiply the terms.</p>
<p>(a+b+c+d) * (e+f) = ae+af+be+bf+ce+cf+de+df</p>
<p>8 terms</p>
<p>Also put constant. If it was sinusoidal that would mean some heights were achieved quicker than others but speed was constant?</p>
<p>For the trigonometric graph one that asked for A what did you put?</p>
<p>1/2</p>
<p>it’s the amplitude of the graph of sin x</p>
<p>I’m not in AP physics, but everyone keeps saying the line for the ferris wheel should be straight because the velocity was constant. Wouldn’t the vertical vs horizontal velocities still differ, but just combine to get the same total velocity?</p>
<p>Ok I put 1/2 too.</p>
<p>The ferris wheel one is just understanding circles. </p>
<p>I know that put that way it sounds really simple, but think about a circle rolling</p>
<p>It’s sinusoidal because that is the shape the height of a particular point will make.</p>
<p>It’s definitely sin graph for circles.</p>
<p>The speed of the circle is divided to the x speed and y speed. At the bottom, there is no y speed and at farthest right, all the speed is y</p>
<p>What was the f(g(-4))? -16 or 16?</p>
