Question

Find the distance between points C(-1, -1) and D(6, 2) to the nearest tenth.

Answer 1

Answer:

≈ 7.6

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (6, 2)

d = $\sqrt{(6+1)^2+(2+1)^2}$

  = $\sqrt{7^2+3^2}$

  = $\sqrt{49+9}$

  = $\sqrt{58}$ ≈ 7.6 ( to the nearest tenth )
