F(n) = 11
g(n) = (3/4)^(n - 1)
To create a geometric sequence. multiply f(x) and g(x)
an = f(x)g(x) = 11(3/4)^(n - 1)
9th term is 11(3/4)(9 - 1) = 11(3/4)^8 = 11(0.100) = 1.101
Everything that is not 4/9
Answer:
9,420.0 cubic feet
Step-by-step explanation:
D^2 - 4d = 3d
d^2 - 7d = 0
d(d - 7) = 0
d = 0 or d - 7 = 0
d = 0 or d = 7
3/8=9/24 and 1/6=4/24
9/24+4/24=13/24
