Answer:
1 < a < 13/5
Step-by-step explanation:
2 < 2a - 3(1 -a) < 10
2 < 2a - 3 + 3a < 10
2 < 5a - 3 < 10
2 + 3 < 5a - 3 + 3 < 10 + 3
5 < 5a < 13
5/5 < 5a/5 < 13/5
1 < a < 13/5
I think it is 20 seconds because when you multiply six times x, you get twelve. And in this case, the x equals two. So, because you multiplied two to six, you do the same thing to the ten seconds, which is twenty. Sorry if this is the wrong answer.

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
