6.4 rounded to the nearest tenth

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 numbers from the two points gives:

$d = sqrt((color(red)(6) - color(blue)(2))^2 + (color(red)(8) - color(blue)(3))^2)$

$d = sqrt((4)^2 + (5)^2)$

$d = sqrt(16 + 25)$

$d = sqrt(41)$

$d = 6.4$ rounded to the nearest tenth
