Can someone help me with this question please?

as below :  also Mrs. Billerman sounds like a tough teacher :P

Step-by-step explanation:

so they want to know.. what the answer is .. if x = 4 after you take the derivative ..  

so remember b/c there is a minus sign in there you can break this up into two separate derivatives.  which helps a lot

like this

d/dx 5 dx  -   d/dx 32 dx ... good so far? (point A )

the first one you can probably do

10x  -  32* d/dx (x) ^ (1/2) dx     see? move the 32 out front.. it's not needed  inside the derivative and the put a 1/2 in the exponent place on the x  good to here? ( point B)

10x -  32 * 1/2*x ^( -1/2)      good so far? ( point C)

put in the 4 into x now  :P yay we are almost done.. cookies? when we're done?  :P

10(4) -32*(1/2)(4)^(-1/2)   good to here?  (point D)

40 -16  * 1/√4      make sense?  (point E)

40-16*1/2     they make it easy form here. huh.. got it?

40-8

32  also  show your work  :D

15 batches are the most you can make
