Question

Find the derivative

Answer 1

\[\huge y=(15d)e^{\frac{ -d }{ 5 }}\]

Answer 2

6 penguins on board!

Answer 3

\[\huge y= (15d)'(e^{\frac{ -d }{ 5 }})+(15d)((e^{\frac{ -d }{ 5 }})'\]

Answer 4

y'= *

Answer 5

Are you differentiating with respect to d or x?

Answer 6

Or is d a constant?

Answer 7

"d"*

Answer 8

\[\huge y'= 15(e^{\frac{ -d }{ 5 }})-30d(e^{\frac{ -d }{ 5 }})\]

Answer 9

Ah sorry, my eyes went somewhere. Sorry about that.

Answer 10

d is a constant :P

Answer 11

d is the variable, not a constant.

Answer 12

and you are almost correct. The 30 is not right.

Answer 13

check your second part of your answer

Answer 14

(e^(-d/5)' = -(1/5)e*(-d/5)
