Answer:
The sequence is geometric.
![\texttt{Recursive formula, }t_n=10t_{n-1}](https://tex.z-dn.net/?f=%5Ctexttt%7BRecursive%20formula%2C%20%7Dt_n%3D10t_%7Bn-1%7D)
Step-by-step explanation:
If the sequence is arithmetic common difference will be same, if the sequence is arithmetic common ratio will be same.
Here the sequence is 4, 40, 400, 4000, …
Difference between terms
40 -4 = 36
400 - 40 = 360
They are not same , so the sequence is not arithmetic.
Ratio between terms
40/4 = 10
400/40 = 10
4000/400 = 10
They are same , so the sequence is geometric.
Now we need to find recursive formula for the sequence.
Recursive formula for GP
![t_n=rt_{n-1}](https://tex.z-dn.net/?f=t_n%3Drt_%7Bn-1%7D)
1. 23v + 10v
2. 8v + 120 < 23v + 10v
3.
120 < 15v + 10v
120 < 25v
v > 4.8
Hope this helps!
Answer:
C. n=4 or n=-4
Step-by-step explanation:
10lnl-3=37 original problem
+3=+3 add 3 to both sides
10lnl=40 solve that portion
<u>10lnl=40</u>
10 divide both sides by 10 to isolate the variable
lnl=4 since n is an absolute value, it is the distance from zero making the solution 4 or -4.
Answer:
5 friends
Step-by-step explanation:
To find out how many friends she gave cany, you must divide the number of candy total by how many pieces each friend got.
Therefore-
30 divided by 6 = 5
The answer is 5
