Question

Find the distance between the two points rounding to the nearest tenth (if necessary). (3,3) and (6,6)

Answer 1

d ≈ 4.2

Explanation:

calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (3, 3 ) and (x₂, y₂ ) = (6, 6 )

d =
`√((6-3)^2+(6-3)^2)`

=
`√(3^2+3^2)`

=
`√(9+9)`

=
`√(18)`

≈ 4.2 ( to the nearest tenth )
