The answer is C. f(x) = 0.05
The answer is 3x-14 . . . . . . . . . . . .
Answer:

Step-by-step explanation:
we have given x'=(24-16)x=8x
x' denotes the differenation
differentiation is performed with respect to t
by variable separable method we can write

on integrating both side

(property of log )
so the solution for x will be 
4 Americans can arrange themselves in 4! ways.similarly ,3 Frenchmen can arrange themselves in 3! ways.3 Englishmen can arrange themselves in 3! ways.now these 3 groups of same nationality people can be arranged among themselves in 3! ways.so total number of ways = 3!4!3!3!
