Question

Find the distance between each pair of points, to the nearest tenth. (-1,0),(4,12)

Answer 1

d = 13

Explanation:

calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (- 1, 0 ) and (x₂, y₂ ) = (4, 12 )

d =
`√((4-(-1))^2+(12-0)^2)`

=
`√((4+1)^2+12^2)`

=
`√(5^2+144)`

=
`√(25+144)`

=
`√(169)`

= 13
