Question

The distance between the points $(0,0)$ and $(x_1,y_1)$ is _____ units.

• A. $\sqrt{x_1^2+y_1^2}$
• B. $\sqrt{x_1+y_1}$
• C. $\sqrt{x_1^2+y_1}$
• D. $x_1+y_1$

Answer 1

The correct option is A $\sqrt{x_1^2+y_1^2}$

The given points are $(0,0)$ and $(x_1,y_1)$

Distance between given points is

$d=\sqrt{(x_1-0{)}^2+(y_1-0{)}^2}\Rightarrow d=\sqrt{x_1^2+y_1^2}$

Hence, $Op-A$ is correct.
