How does the decimal point move when 0.45 is multiplied by 10 to the 4 power.

450,000.

Step-by-step explanation:

The decimal point moves to the right, because 10 to the power of 4 is 10,000.

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
