maybe this? or does this work better? if you increase your speed by 50% by what factor does the power requirement increase? Last edited by GIjoefan1976; November 14th, 2017 at 06:20 PM. Reason: more info

I see nothing after "maybe this" and "or does this work better" is not much better than what you had originally. But I can read the table of values. Notice that $\displaystyle \frac{2840}{355}= 8= 2^3$, $\displaystyle \frac{9585}{355}= 27= 3^3$, $\displaystyle \frac{22720}{355}= 64= 4^3$. Of course, the same fractions for the x values are 2, 3, and 4. That is, for each of those we can write the function as $\displaystyle P= 355\left(\frac{v}{10}\right)^3$. The 'integer exponent' here is '3'!

I then typed out the question I was stuck on.... If you increase your speed by 50% by what factor does the power requirement increase? so am I suppose to see it as being raised to 15 as wouldn't 20 be a 100 percent?...the answer they got was 3.375
