Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-5, -2) and point (8, -3) rounded to the nearest tenth?

10.3 units

12.6 units

1 unit

13 units

Respuesta :

Option D: 13 units is the distance between the two points

Explanation:

Given that the points are [tex](-5,-2)[/tex] and [tex](8,-3)[/tex]

We need to find the distance between the two points.

The distance between the two points can be determined using the distance formula,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Let us substitute the points [tex](-5,-2)[/tex] and [tex](8,-3)[/tex] in the above formula, we get,

[tex]d=\sqrt{(8-(-5))^2+(-3-(-2))^2}[/tex]

Simplifying the terms within the bracket, we have,

[tex]d=\sqrt{(8+5)^2+(-3+2)^2}[/tex]

Adding the terms within the bracket, we get,

[tex]d=\sqrt{(13)^2+(-1)^2}[/tex]

Squaring the terms, we have,

[tex]d=\sqrt{169+1}[/tex]

Adding, we get,

[tex]d=\sqrt{170}[/tex]

Simplifying, we have,

[tex]d=13.04[/tex]

Rounding off to the nearest tenth, we get,

[tex]d=13.0 \ units[/tex]

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.
