    cost of a cable is \[6\sqrt{2}\]. explain meaning of \[\int\limits_{25}^{30}6\sqrt{x}\] in context of this problem

    well ok: company makes cables for 120 bucks a meter. for a fixed length, the price to make the cable is 6 rad 2.

    then those numbers on top and beneath your integral sign would most likely be an interval of length of some sort...

    the "line" integral is a squareroot function... I know that much :)

    srry the 120 refers to the company SELLING price

    what is a line integral o.O

    the line integral is: \[\int\limits_{} \sqrt{[f'(x)]^2+[g'(x)]^2} dx\]

    or if y is a function of x...then f'(x) = 1 and you put in the functiuon for y on the other side

    yep, same concept, your trying to find the length of a curve by looking really close at it until it flattens out

    i think it has something to do with the length of a cable.... yeah, but to be sure id have to know the average rainfall in the amazon...you know the basics :)
