<u>ANSWER</u>
The common ratio is -3.
<u>EXPLANATION</u>
In general, the common ratio of a Geometric Sequence is given by:

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.
The given sequence is -2,6,-18,54
Using the first two terms the common ratio is

We could also used the second and third terms to get

and so on and so forth.
Therefore the common ratio is -3.
Answer:
hailey played the game longer (1/3 hour).
Step-by-step explanation:
You are deciding which is greater: 1/6 or 1/3.in this case, a smaller denominator (such as 3) produces a greater value.1/3 has a smaller denom. than does 1/6, so 1/3 is greater than 1/6.hailey played the game longer (1/3 hour).
(by 0 i mean the "theta" sign)
cot0 x sec0 = csc0
(cos0/sin0) x (1/cos0) = 1/sin0
1/sin0 = 1/sin
1.86 is your answer
1/3*4/5=4/15
4/14*7/1=28/15
28/15=1.86
Your answer is 1.86
Hope this helps.
