Answer:
D=3.60
Step-by-step explanation:
[tex]D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Where
[tex] (x_1,y_1) = (5,1) [/tex]
[tex] (x_2,y_2) = (3,4) [/tex]
Replacing these values in the distance formula
[tex]D =\sqrt{(5-3)^2+(1-4)^2}[/tex]
[tex]D =\sqrt{(2)^2+(-3)^2}[/tex]
[tex]D =\sqrt{4+9}[/tex]
[tex]D =\sqrt{13}[/tex]
[tex]D =\sqrt{13}[/tex]
[tex]D= 3.60[/tex]
