Question

Find the distance between the two points rounding to the nearest tenth (if necessary)

(8,7) and (1,-2)

Answer 1

You can easily look it up… so here is a pic

Answer 2

Answer:

≈ 11.4

Step-by-step explanation:

Calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)

d = $\sqrt{(1-8)^2+(-2-7)^2}$

   = $\sqrt{(-7)^2+(-9)^2}$

   = $\sqrt{49+81}$

   = $\sqrt{130}$

   ≈ 11.4 ( to the nearest tenth )
