Question

Work out the length of AB. Give your answer to 3 significant figures

Answer 1

Answer:

D = 9.80

Step-by-step explanation:

To find AB, we'll use the distance formula:

Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

D = $\sqrt{(10-1)^2+(3-7)^2}$

D = $\sqrt{(9)^2+(-4)^2}$

D = $\sqrt{81+16}$

D = $\sqrt{96}$

D = 9.80 (Upto 3 sfs)
