The answer is 6 I use Photomath just type the questions in and it gives you the answer
a. Recall that
For , we have
By integrating both sides, we get
If , then
so that
We can shift the index to simplify the sum slightly.
b. The power series for can be obtained simply by multiplying both sides of the series above by .
c. We have
Vocab:
Parallel = same slope
Perpendicular = opposite sign and reciprocal slope
-5/2 opposite and reciprocal = 2/5
Solution: they are perpendicular
Answer:
The answer should be 1/12 because a a cube has 6 sides rolling it twice would make it 12.
Hope This Helps!
