Let's tell the scientific notation of this number and write as quickly as possible a) 571000000

5.71 x 10⁸

Step-by-step explanation:

571,000,000 = 5.71 x 10⁸

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
