The three acute angles are 70 and the obtuse ones are 110.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30.
Divided 200000 in half to get 100000 and the same to 800 then
change to percentages 4%
4% is the answer
thank me
Answer:
Its A
Step-by-step explanation:
Answer:
a₈ = - 1 / 128
Step-by-step explanation:
Given:
First four terms of the sequence
a₁= 1, a₂= - 1/2, a₃= 1/4 and a₄= -1/8
First we recognize that this is a geometric series (sequence) and we must calculate quotient q.
q = a₂/a₁ = a₃/a₂ = (-1/2)/1 = (1/4)/(-1/2) = - 1/2
q = - 1/2
Formula for calculating n-th term is:
aₙ = a₁ · qⁿ⁻¹
According to this:
a₈ = 1 (-1/2)⁷ = - 1/ 128
God with you!!!
