Question

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

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

Answer 1

≈ 11.4

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 =
`√((1-8)^2+(-2-7)^2)`

=
`√((-7)^2+(-9)^2)`

=
`√(49+81)`

=
`√(130)`

≈ 11.4 ( to the nearest tenth )
