Abit is a 0 or a 1. a bit string of length 8 is a sequence of 8 digits, all of which are either 0 and 1. (a) how many bit strings of length 8 are there?

There are 256 bit strings of length 8.

Explanation:

Each bit is either 0 or 1, so the base is 2.

The length is 8, so the power is 8.

Therefore the calculation is 2^8 = 256.

Let me know if you have any questions.

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
