81, 108, -144, 192,
which formula can be used to describe the sequence?
a. f(x)= -81 (4/3)^x-1
b. f(x)= -81 (-3/4)^x-1
c. f(x)= -81 (-4/3)^x-1
d. f(x)= -81 (3/4)^x-1

C

Step-by-step explanation:

The terms form a geometric sequence with common ratio r

r = = = ......

r = = = -

The n th term formula of a geometric sequence is

= a ← a is the first term

here a = - 81, hence

f(x) = - 81 → C

is this a multiple choice question?

if so it's a and c

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
