To determine where \( \sqrt{105} \) lies on a number line, we can calculate its approximate value.
Calculating \( \sqrt{105} \):
- We know that \( 10^2 = 100 \) and \( 11^2 = 121 \). So, \( \sqrt{105} \) must be between 10 and 11.
- To narrow it down, we can try some values:
- \( 10.2^2 = 104.04 \) (too low)
- \( 10.3^2 = 106.09 \) (too high)
This tells us that \( \sqrt{105} \) is between 10.2 and 10.3.
To find the nearest half (0.5), we note that:
- 10.2 rounds to 10.0
- 10.3 rounds to 10.5
Thus, \( \sqrt{105} \) is between approximately 10.2 and 10.3, so it is:
between 10 and 10.5.
So the correct response is: between 10 and 10.5.
