Answer:
≈ 9.4
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = P (- 4, - 2 ) and (x₂, y₂ ) = Q (4, 3 )
PQ = [tex]\sqrt{(4-(-4))^2+(3-(-2))^2}[/tex]
= [tex]\sqrt{(4+4)^2+(3+2)^2}[/tex]
= [tex]\sqrt{8^2+5^2}[/tex]
= [tex]\sqrt{64+25}[/tex]
= [tex]\sqrt{89}[/tex]
≈ 9.4 ( to 1 dec. place )
