Is this correct? The answer I picked was the only one that had no limit. If I did it correctly the other choices limit was zero.

andriy [413]

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.

Use the fundamental identities to simplify the expression.<br> 9tantheta9cottheta/9sectheta

Mnenie [13.5K]

[9tan(θ) * 9cot(θ)] / 9sec(θ)

First cancel out the 9's:

tan(θ)cot(θ)/sec(θ)

Recall the following trig identities:

tan = sin/cos

cot = cos/sin

sec = 1/cos

Thus, we can rewrite the expression as:

[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))

In the numerator, the sine's and cosine's cancel each other out:

1 / (1/cos(θ))

which we can rewrite as cos(θ).

Round 462093 to the nearest 10 000

Georgia [21]

462,093 round to the nearest ten thousand is 60,000 because 2 is less and 6 is greater so 6 stay the same
