Question

To the nearest tenth, find the approximate distance between points B and D.

A. 9.8 units
B. 8.1 units
C. 5 units
D. 3.6 Units

(pic below)

Answer 1

The answer is A. 9.8

Answer 2

Distance = 9.8 units

Explanation:

Point B is (-2,5) and point D is (2,-4)

LEts find the distance between these points. USe distance formula

`D=√((x_2-x_1)^2 +(y_2-y_1)^2)`

(-2,5) is (x1,y1) and (2,-4) is (x2,y2)

Plug in the values and find out the distance

`D=√((x_2-x_1)^2 +(y_2-y_1)^2)`

`D=√((2+2)^2 +(-4-5)^2)`

`D=√((4)^2 +(-9)^2)`

`D=√(97)`

Distance = 9.8 units
