x^2=3136+4225-(0.2588) x^2=3136+4225+0.2588 x^2=7361.26 x=85.8

Try again-- x^2=3136+4225-7280(-0.2588) x^2=9245.06 x=96.2 cm

well, since water potential is pressure + solute concentration, that means that it would be the sum of the beaker AND the dialysis tubing. so. -4 + -1 is -5. Should be the answer. :P

To compare these decimals, line them up and down like this 0.205 0.210 (You can always add a zero to the end to make lining up more accurate, but be sure to drop it once you get your answer) Ok so lets start with the Zeros, they are equal. so next, the 2'...

oh the answer is k they said the integral of the function i said to find from 0 to 2 is equal to the integral from 0 to 8 WHYYY

15 years ago

Why would you say that? I understand you use u subsitution u= x^3 and then eventually you get an integral from 0 2 of the function but i dnt understand why the integral from 0 to 2 and the integral from 0 to 8 would be the same?

square A=S^2, P=p (side of the square must be S, p=4(S)) Regular Hexagon P=T and side=h (side is total perimeter divided by the sides of the hexagon (6)) therefore, h+p in terms of S and T. (P/6)+ 4S
