Find a8 when a1 = 40,000, r = 0.1
2 answers:
Answer:
0.004
Step-by-step explanation:
The first term for this geometric series, a1, is 40,000
The common ratio for this geometric series, r, is 0.1
The eight term for this geometric series, a8, is given by the equation a1*r^7
a8=40000*0.1^7
=0.004
Answer:
a8 = 0.004
Step-by-step explanation:
Q is abt a geometric series given by the eqn: an = a1*r^(n-1)
given a1 = 40000, r = 0.1
an = 40000*(0.1)^(n-1)
a8 = 40000*(0.1)^(8-1)
= 40000*(0.1)^7
= 0.004

- (x - x₁)(x - x₂) = 0
- (x - (-3))(x - 5) = 0
- (x + 3)(x - 5) = 0
- x² + 3x - 5x - 15 = 0
- x² - 2x - 15 = 0
