Find the distance between point A(0,4) and point B (-2,-7) rounded to the nearest tenth.

A.3.6
B. 11.1
C.11.2
D.3.7

Answer 1

C.11.2

Explanation:

The distance between 2 points is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

= sqrt( ( -2-0)^2 + (-7-4)^2)

= sqrt( (-2)^2 + (-11)^2)

= sqrt( 4 + 121)

= sqrt(125)

= 11.18033989

To the nearest tenth

11.2
