Step-by-step explanation:
These are all examples of p-series:
∑(1 / nᵖ), where p>0.
If p > 1, the series converges. If 0 < p ≤ 1, the series diverges.
First option:
∑(1/n⁵)
Here, p = 5. Since 5 > 1, the series converges.
Second option:
∑((√n+3)/n³)
∑((√n)/n³) + ∑(3/n³)
∑(1/n^2.5) + 3 ∑(1/n³)
In the first sum, p = 2.5. In the second sum, p = 3. Both are greater than 1, so the series converges.
Third option:
∑((n−4)/(n⁴√n))
∑(1/(n³√n)) − ∑(4/(n⁴√n))
∑(1/n^3.5) − 4 ∑(1/n^4.5)
In the first sum, p = 3.5. In the second sum, p = 4.5. Both are greater than 1, so the series converges.
Fourth option:
∑(1/∛n)
∑(1/n^⅓)
Here, p = ⅓. This is less than 1, so the series diverges.
Note: if a series is converging, then the limit is 0.
However, if the limit of a series is 0, it does not necessarily mean that series is converging.
Here, the limit of all 4 options is 0. However, the fourth option is a diverging series.

Answer:
The are 21 roses in the bouquet
Step-by-step explanation:
Since the 49 roses are distributed evenly amongst the 7, then what each of the seven will get would be 49/7 = 7 roses
So 3 of the friends combine every of theirs to make a bouquet
The number of roses in the bouquet will be 7 + 7 + 7 = 21 roses
∠ XYT
∠ XTY
∠ TXY
Solution:
Given: △ RST ≅ △ TXY
We are given ΔRST and ΔTXY are congruent to each other.
If two triangles are congruent to each other then their corresponding parts are equal.
Please see the attachment of two triangles.
∵ ∠R=∠T By CPCT
∵ ∠XYT=∠STR By CPCT
∵ ∠XTY=∠SRT By CPCT
∵ ∠TXY=∠RST By CPCT
CPCT: Congruent part of congruence triangle.
