Question

Find the distance d(p1,p2) between points p1 and p2. P1=(1,-2) p2=(2,5)

Answer 1

5
`√(2)`

Explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

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

d =
`√((2-1)^2+(5+2)^2)`

=
`√(1^2+7^2)` =
`√(50)` = 5
`√(2)`
