Question

Find the distance between (2,0) and (8, -3) The distance d between the points (X1, Yı) and (x2, Y2) is
d = Vixy - x)2 + (y2 + y)2.

Answer 1

Answer:

d =3√5

Step-by-step explanation:

$(2,0) =(x_1,y_1)\\ (8, -3) =(x_2,y_2)\\\\d =\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d=\sqrt{\left(8-2\right)^2+\left(-3-0\right)^2}\\\\d = \sqrt{(6)^2+(-3)^2}\\ \\d = \sqrt{36+9}\\ \\d = \sqrt{45} \\\\d = 3\sqrt{5}$
