Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 9 terms and select the correct answer below.
zavuch27 [327]
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.

Sn=a[(1-r^n)/(1-r)]

In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9

S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563

Answer: A. -976563

A glass container can hold 216a^3 cubic cm of water. inside the glass container is a metallic cube with a volume of 64b^3 cubic
xz_007 [3.2K]

Answer:

16(3a-2b)(4a^2+3ab+2b)

Step-by-step explanation:

We will be able to fill the glass up to the amount of water possible to hold in the glass, minus the amount in the cube. This means it will be able to hold 216a^3-64b^3=(6a)^3-(4b)^3cubic cm of water.

Using the difference of cubes formula(you can prove this by expanding back out again), we get that (6a^3)-(4b)^3=(6a-4b)((6a)^2+(6a)(4b)+(4b)^2)=(6a-4b)(36a^2+24ab+16b)=8(6a-4b)(4a^2+3ab+2b)=16(3a-2b)(4a^2+3ab+2b)

Therefore, the answer is \boxed{16(3a-2b)(4a^2+3ab+2b)} cubic centimeters and we're done!
