work out the length of ab, give your answer to 3 significant figures

Answer:
D = 9.85 units
Step-by-step explanation:
A (1,7) and B(10,3)
Using Distance Formula to find the length
=> Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
=> D = [tex]\sqrt{(10-1)^2+(3-7)^2}[/tex]
=> D = [tex]\sqrt{(9)^2+(-4)^2}[/tex]
=> D = [tex]\sqrt{81+16}[/tex]
=> D = [tex]\sqrt{97}[/tex]
=> D = 9.85 units (Upto 3 sfs)
