Question

Find the distance between points P(6, 2) and Q(5, 9) to the nearest tenth.

Answer 1

`d = 10`

Explanation:

Distance formula

`d =\sqrt{(x_2-x_1)^(2) + (y_2-y_1)^(2) }` ------------ (1)

Here

`(x_1, y_1) = (6, 2) \ \ \ and \ \ \ (x_2, y_2) = (5, 9)`

Substituting values in equation (1)

`d =\sqrt{(5-6)^(2) + (9-2)^(2) }`

`d =\sqrt{(-1)^(2) + (7)^(2) }`

`d = \sqrt { 50 }`

`d=7.07`

the nearest tenth is 10
