A girl walks 4 km towards west, then she walks 3 km in a direction `30^o` east of north and stops. Determine the girl’s displacement from her initial point of departure.

A girl walks 4 km towards west, then she walks 3 km in a direction 30^circ east of north and stops. Determine the girl's displacement from her initial point of departure.

Represent graphically a displacement of 40 km, 30^o east of north.

Rita goes 20 km towards east from a point A to the point B. From B, she moves 30 km towards west along the same road. If the distance towards east is represented by a positibe integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?

Satpal walks 2/3 km from a place P, towards east and then from there 1 5/7 km towards west. Where will he be now from P?

A car travels due east on a level road for 3 km. It then turns due north at an intersection and travels 4 km before stopping. The magnitude of the resultant displacement of car is

A man leaves his home early in the morning to have a walk. He arrives at a junction of roads A and B as shown in figure. He takes the following steps in later journies : (i) 1 km in North direction. (ii) Changes direction and moves in North-East direction for 2 sqrt(2) km. (iii) Changes direction and moves Southwards for distance of 2 km. (iv) Finally he changes the direction and moves in South-East direction to reach road A again. Now if roads A and B are taken as X-asix and Y-axis, then visible point representing the graph of y = f(x). Then the value of x at which function f(x) is discontionous
