See the entire solution process below:

The formula for calculating the distance between two points is:

$d = sqrt((color(red)(x_2) - color(blue)(x_1))^2 + (color(red)(y_2) - color(blue)(y_1))^2)$

Substituting the values from the points in the problem gives:

$d = sqrt((color(red)(5) - color(blue)(4))^2 + (color(red)(5) - color(blue)(2))^2)$

$d = sqrt(1^2 + 3^2)$

$d = sqrt(1 + 9)$

$d = sqrt(10) = 3.162$

The distance between the two points is $sqrt(10)$ or $3.162$ rounded to the nearest thousandth.
