Question

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (0, 5) and point (3, -1) rounded to the nearest tenth?
a. 6.7 units


b. 11.2 units


c. 2.4 units


d. 5.5 units

Answer 1

$\sqrt{(3-0)^2+(-1-5)^2}=\sqrt{3^2+(-6)^2}=\sqrt{45}\approx 6.7$

answer (a)
