This is a bit of a stretch but do you know how the problem would differ if you had to dump out three cups per two seconds rather than one cup per one second.

Lake Erie holds 116 cubic miles of water. Suppose you start dumping out the entire volume of Lake Erie using a cone cup. A typical cone cup has a diameter of 2.75 inches and a height of 4 inches. About how long would it take you to empty the lake if you could dump out one cup per 2 seconds? Use...

Hello. I'm confused as to how you get from x^2-x+ix-x-ix+1-i^2 to x^2-2x+2 . Can you please elaborate? So far I've tried simplfying up to: =x^2-x+ix-x-ix+1-i^2 = x^2-(x-x)+(ix-ix)+(1- √ ̅-1 ) = ? Note: I substituted i^2 for √ ̅-1 . Is (1- √ ̅-1 ) =2 ? And how? Thank you again.

Simplify the function f(x)= (x-(1+i))(x-(1-i)) . Is the function you wrote in factored form [ f(x)= (x-(1+i))(x-(1-i)) ] , the same as the original function in standard form [ f(x) = x^2 - 2x +2) ] ?
