Answer:
See below
Step-by-step explanation:
So, on the complex plane, we see that
Therefore,
Since we added the complex numbers, we can see that the real part of is 8 and the imaginary part of is -2. Remember that complex numbers are written in the form of , so either the real or imaginary part can both be negative.
Answer:
The sequence is geometric.
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
Where is the picture of the shape?
Answer is C. because you flip the fraction upside down to find its reciprocal
