1.

The distance between the points (0,5) and (-5,0) isA. 5B. `5sqrt(2)`C. `2sqrt(5)`D. 10

Answer» Correct Answer - b
`:.` Distance between the points `(x_(1),y_(1))and (x_(2),y_(2)),`
d`=sqrt((x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2))`
Here, `x_(1)=0,y_(1)=5andx_(2)=0`
`:.` Distance between the points (0,5) and (-5,0)
`=sqrt((-5-0)^(2)+(0-5)^(2))`
`=sqrt(25+25)=sqrt(50)=5sqrt(2)`
