Answer:
Step-by-step explanation:
The given expression describes the GP with
<u>The first term:</u>
- t = 80(1.23²⁻²) = 80(1.23⁰) = 80
<u>The common ratio: </u>
It is required to find the sum of the terms from 2 (the bottom number of sigma) through 29 (the top number of sigma)
The number of terms is
The sum of the first 28 terms is
- Sₙ = t(rⁿ - 1)/(r - 1)
- S₂₈ = 80(1.23²⁸ - 1)/(1.23 - 1) = 114125.75573 ≈ 114126 (rounded)
The distance of PQ is sqrt 40 or ≈ 6.32
Answer:2-4h
Step-by-step explanation:
3(2-0.9h)+(-1.3h-4)
6-2.7h-1.3h-4
6-4h-4
2-4h
