Suppose h = f○g. find h'(0) given that f(0) = 8, f '(3) = -4, g(0) = 3, and g '(0) = 9.

i understand that the derivative of h is as follows
h'(x)=f(g')+g(f')
therefore
h'(0)= 8(9)+3(f')
but i can not figure out how to find f'

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
