The answer is x=0 cause everything cancels out
1. 0.00262 or 131/50000
2. 0.436 or 109/250
3. 0.00773 or 773/100000
4. 0.0565 or 113/2000
Answer:1250 units
Step-by-step explanation:
circumference=7850
Radius=?
Radius=circumference ➗ (2xπ)
Radius=7850 ➗ (2 x 3.14)
Radius=7850 ➗ (6.28)
Radius=1250 units
This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence:

If a1=1.6 then:

The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
