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)
Fill in 33 boxes and the do the math on a calculator witch would be 11. then out line the 11 shaded boxes all 3 times... does this make sense?
Answer:
(-1, -7)
Step-by-step explanation:
Used desmos, also, in these situations I believe you can take the number inside the brackets and make it negative and keep the number outside the same to find the vertex.
1.00-0.06 = 0.94
7.95 x 0.94 = 7.473, round to 7.47 without the tax
Answer:
Step-by-step explanation:
+ 3 = -z
= -z - 3
Square both sides , we have
2z = ![(-z-3)^{2}](https://tex.z-dn.net/?f=%28-z-3%29%5E%7B2%7D)
2z =
+ 6z + 9
re arranging the equation , we have
+ 6z - 2z + 9 = 0
+ 4z + 9 = 0
This will give a complex roots , solving by quadratic formula
z = -2 +
i , -2 -
i
