-5/13
Formula: Y2-Y1/X2-X1
D. f(x)= x*-9x^o+2x^2-4x+10
I believe A and B are the ones. As for explaining? hmm. I would honestly say that any number to the right of a number is a tenth of the place above it. But then again, it's optional to explain ;P
The answer too your question is 65 it is equal to the square root of 65
The answer for either field being harvested is 6.25 days (acres/(rate of harvest))
The answer is probably seven because, even though a day can be divided into parts, the fields are done the seventh not the sixth. (I'm assuming the problem calls for whole days)
