Answer:
y=-1/2x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-3=-1/2(x-(-2))
y-3=-1/2(x+2)
y=-1/2x-2/2+3
y=-1/2x-1+3
y=-1/2x+2

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)
