Answer:
f(x+1) = -3/4 × f(x)
Step-by-step explanation:
first of all, the sign of the numbers in the sequence is alternating. so, there must be a "-" involved.
that eliminates the first and third answer options.
and the absolute values of the numbers in the sequence are going down. |f(x+1)| < |f(x)|
that eliminates the fourth answer option, as this says that
|f(x)| < |f(x+1)|. and that is the opposite of how the actual sequence behaves.
Answer:
B would be the answer:))
Step-by-step explanation:
Divide 2 by 9
Answer:
B
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = 
area of base × perpendicular height (h)
area of square base = 12 × 12 = 144 units² and h = 8, hence
V = × 144 × 8 = 
= 384 units³ → B
Answer:
C) 7.54
Step-by-step explanation:
first, line up the decimal point, which has been done properly. now, add as though the decimal point doesn't exist, just add normally. you get 754. now, you slide the decimal point down, there are 2 places after the decimal (we assume that 6.8 is 6.80, doesn't change anything), so that's how many will be there in the answer. therefore, 7.54.
