Number 7is 64. 8 is 486 because 3 to the 5th is 243 then multiply by 2.
9 is 1003.092
10. Is 5
Answer:
12.97 km
Explanation:
In order to find the resultant displacement, we have to resolve each of the 3 displacements along the x and y direction.
Taking north as positive y direction and east as positive x-direction, we have:
- Displacement 1: 2.00 km to the north
So

- Displacement 2: 60.0° south of east for 7.00 km
So

- Displacement 3: 9.50 km 35.0° north of east
So

So the net displacement along the two directions is:

So, the distance between the initial and final position is equal to the magnitude of the net displacement:

On half life is 5370 years; 6 half lives have passed. You just multiply,
5370*6 = 32,220 years
