When represented on number line will be to- 5of zero. (4) |

Answer» Answer Draw number line as shown in the figure. Let the point O represent 0(zero) and point A represents 2. Draw PERPENDICULAR AX at A on the number line and cut-off arc AB=1unit. We have OA=2 units and AB=1unit Using pythagoras theorem, we have, OB 2 =OA 2 +AB 2
OB 2 =(2) 2 +1 2 =5 OB= 5
Taking O as the centre and OB= 5
as radius draw an arc cutting real line at C. Clearly, OC=OB= 5
. Hence, C represents 5
on the number line. |
