Question

the concentration of 100mg of a drug in the bloodstream can be modelled by the function C=te^-4t.

Find the rate of change of concentration of the drug at time t.

Answer 1

@marnie12345 Can you take derivative applying product rule?

Answer 2

I tried to but got confused.

Answer 3

C'=1*e^-4t(4)
?

Answer 4

d/dt e^(-4t) = -4e^(-4t)

Answer 5

so C'=4e^-4t
what do i do after that?

Answer 6

I'm not sure what you mean by that?

Answer 7

So you don't know what is product formula (u v)' is?

Answer 8

I guess not

Answer 9

Please check your note/ textbook for the formula, then I'll show you how to apply :)
