Answer:
C
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = T(1, - 1) and (x₂, y₂ ) = U(2, - 4)
d = [tex]\sqrt{(2-1)^2+(-4+1)^2}[/tex]
= [tex]\sqrt{1^2+(-3)^2}[/tex]
= [tex]\sqrt{1+9}[/tex]
= [tex]\sqrt{10}[/tex] ≈ 3.16 units ( to the nearest hundredth ) → C
