Answer:

≈ 6.08 units

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = P(3, - 2) and (x₂, y₂ ) = K(4, - 8)

PK = [tex]\sqrt{(4-3)^2+(-8+2)^2}[/tex]

     = [tex]\sqrt{1^2+(-6)^2}[/tex]

     = [tex]\sqrt{1+36}[/tex]

     = [tex]\sqrt{37}[/tex] ≈ 6.08 ( to 2 dec. places )
