Answer 1

can you find the 1st derivative?

Answer 2

yeah the first is 10/2y

Answer 3

so \[y'=\frac{5}{y}\]


take the derivative again

Answer 4

I got \[-200/2y^3\] can you show me the work you did to get your answer

Answer 5

I don't get that as an aswer

Answer 6

\[y''=5\frac{-1}{y^2}y'=-5\frac{1}{y^2}\frac{5}{y}=-\frac{25}{y^3}\]

Answer 7

i got it now thanks a lot

Answer 8

no problem
