"Hint: Pay attention to the units of measure. You may have to convert from feet to miles several times in this assignment. You can use 1 mile = 5,280 feet for your conversions."
Please let me know if I did this correct for b... 100=C/(3,963)^2 100=C/15,705,369 100*C=(C/15,705,369)*C 100C=15,705,369 100C/100=15,705,369/100 C=157,053.69
So would my equation be C=100/(3963)^2 ...I'm confused
Ok, I went back and tried again. The equation I found when solving for r is r=sqrt(C/w) Is this correct? Then in b I would plug in the 100 for w, and the 3,963 for r to find the constant, C, correct?
Or, should I leave it as 10d/(10d-20), or do I factor out both of the 10d's to come up with -1/20? Please help me?
Thank you!
Ok, I gave it one more shot. PLEASE let me know if the answer is correct? 10d/[10(d-2)]
Thank you!!
Ok.. So, would it be 11/8a^6p^5?
