Question

Whatbis the ditance between (8,10) and (5,-10) units ​

Answer 1

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{8}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-10})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d = √((5-8)^2+(-10-10)^2)\implies d=√((-3)^2+(-20)^2) \\\\\\ d=√(409)\implies d\approx 20.22`
