Question

Boat A is docked at (4.2, −2) and Boat B is docked at (−5.2, −2). The boats are ____ units apart.

Answer 1

9.4 units

Explanation:

Step one:

given data'

We are given the coordinates

x1=4.2

x2=-5.2

y1=-2

y2=-2

Required

The distance between the points

Step two:

The expression for the distance is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-5.2-4.2)²+(-2+2)²)

d=√((-9.4)²

d= √88.36

d= 9.4 units
