Evaluate the geometric series. Help me!!
1 answer:
Answer:
255
Step-by-step explanation:
The n th term of a geometric series is
= a![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a is the first term and r the common ratio
1
← is the n th term
with a = 1 and r = 2
The sum to n terms of a geometric series is
=
, thus
= ![\frac{1(2^8-1)}{2-1}](https://tex.z-dn.net/?f=%5Cfrac%7B1%282%5E8-1%29%7D%7B2-1%7D)
=
- 1 = 256 - 1 = 255

{x : x ε Z where x<3 & x>4}
Answer:
j=k.m×1/p
j=k.m/p
32=k × 2/4.1
32=2k/4.1
2k=32×4.1
k=(32×4.1)÷2
k=65.6
therefore constant variation K=65.6
