2-10
NEXT QUESTION​

Answer 1

Answer:

$2*10^{-1}$

Step-by-step explanation:

From 0 to 1, there are 5 units, so each of the lines are 1/5.

Hence, it is  0, 1/5, 2/5, 3/5, 4/5, 1

The point P is the first line, so that is 1/5, or in decimal, 0.2

Now we check all the options:

First Choice:  2 ^ -1 = 1/2^1 = 1/2  NO

Second Choice:  2 ^ 0 = 1  (anything to the power 0 is 1)  (NO)

Third Choice:  2 ^ 1 = 2 (NO)

Fourth Choice:  2 * 10 ^ -1 = 2 * 1/10 = 1/5 or 0.2 (RIGHT)

So, last choice is correct.
