Answer:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
\begin{gathered}a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288\end{gathered}an=arn−1, where a=initial term, r=common ratio, n=term numberan=9(2n−1)a6=9(25)a6=288
Answer:
16.5
Step-by-step explanation:
So we have the function:
To find f(2.5), substitute 2.5 for x. Thus:
Multiply:
Add:
And we're done!

Step-by-step explanation:
seven days of decay to find how much is still there on the 8th day
1400 ( 1 - .12)^7 =
Possibility of getting a 2 or 6 is 70-75%
Answer:
B) m + 7
Step-by-step explanation:
We know that we have:
(m + 9)/2 = x
(2m + 15)/2 = y
(3m + 18)/2 = z
We need to find the average.
= (x + y + z)/3
= (m+9/2) + (2m+15/2) + (3m+18/2) / 3
= (m + 9) + (2m + 15) + (3m + 18) / 6
= (6m + 42) / 6
= (m + 7)
Best of Luck!
