Question

can any help me with the deriv. of 16w+6((310/w))+3w???? and the critical ppoints/// i cant get a right answer

Answer 1

\[16w+6(310/w)+3w\] right?

Answer 2

yea

Answer 3

first add like terms
then find derivative of each term using the power rule

Answer 4

would i multiply 6by 310?

Answer 5

yes

Answer 6

remember 1/w = w^-1

Answer 7

so i got the function to be derived... (1860/w)+19w?,,

Answer 8

correct

Answer 9

isnt that the quotient rule then ?
i got (1860/w^2)+19

Answer 10

you could use the quotient rule, however be careful about the sign it should be -(1860/w^2) +19
(f/g)' = f'g - g'f/g^2

Answer 11

now set it equal to zero and solve for w

Answer 12

you should get w^2 = 1860/19

Answer 13

right igot that ...

Answer 14

Answer 15

ok good those are your critical points

Answer 16

ok thanks you lots...
