The problem asks to find the distance $d$ between two points $A(1, 0)$ and $B(5, 2)$ using the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Where:

• $A(x_1, y_1) = (1, 0)$
• $B(x_2, y_2) = (5, 2)$

Substituting these coordinates into the formula:

$d = \sqrt{(5 - 1)^2 + (2 - 0)^2}$

$d = \sqrt{(4)^2 + (2)^2}$

$d = \sqrt{16 + 4}$

$d = \sqrt{20}$

$d \approx 4.47$

Rounded to the nearest tenth, the distance $d$ is approximately $4.5$.
