Question

Find the distance between the points (0, 10) and (–9, 1).A. 14.21B. 12.73C. 16.23D. 20.22

Answer 1

We have the next formula to calculate the distance between 2 points

$d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}$

in our case

(0,10)=(x1,y1)

(-9,1)=(x2,y2)

we substitute the values

$d=\sqrt[]{(1-10)^2+(-9-0)^2}$

then we simplify

$d=9\sqrt[]{2}=12.7279$

Therefore the correct choice is B. 12.73
