Question

Find the distance between the pair of points and then round your answer to the nearest tenth.

(-4,5) and (4.0)
d=(22 – 21) + (92 – 41)?

Answer 1

`d = 9.4 units` (nearest tenth)

Explanation:

Given the distance formula,
`d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`, distance between (-4, 5) and (4, 0) is calculated as follows:

Let
`(-4, 5) = (x_1, y_1)`

`(4, 0) = (x_2, y_2)`

`d = √((4 - (-4))^2 + (0 - 5)^2)`

`d = √((8)^2 + (- 5)^2)`

`d = √(64 + 25)`

`d = √(89)`

`d = 9.4 units` (nearest tenth)
