Answer:
[tex]2*10^{-1}[/tex]
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.
