Question

PLEASE HELP ME I WILL MARK!!

Answer 1

3.2

Explanation:

Distance formula = √ (x₂ - x₁ )² + (y₂ - y₁ )²

Distance =
`√((5-2))^(2)  + (1-2)^(2)`

Distance =
`\sqrt{ {3}^(2)  + ( - 1 )^(2)`

Distance = 3.16227766

Answer 2

3.2

Explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (A(2,2) and (x₂, y₂ ) = B(5, 1)

d =
`√((5-2)^2+(1-2)^2)`

=
`√(3^2+(-1)^2)`

=
`√(9+1)` =
`√(10)` ≈ 3.2 ( nearest tenth )
