Question

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

(-5,-5) and (0,7)

Answer 1

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 ) = (- 5, - 5) and (x₂, y₂ ) = (0, 7)

d =
`√(0+5)^2+(7+5)^2)`

=
`√(5^2+12^2)`

=
`√(25+144)`

=
`√(169)`

= 13
