Use the WeierstrassM-test to show that each of the following series converges uniformly on the given domain:

ryzh [129]

Answer:

Step-by-step explanation:

Given a series $\sum_{k=1}^\infty f(z)$ , the Weierstrass M-test tell us that if we find a sequence of positive numbers $M_n$ such that $|f(z)|\leq M_n$ in a certain domain D, and the series $\sum_{n=1}^\infty M_k$ converges, then the series $\sum_{k=1}^\infty f_k(z)$ converges uniformly in the domain D.

So, our objective is to find the so called sequence $M_k$ . The main idea is to bound the sequence of functions $\frac{z^k}{z^k + 1}$ .

Now, notice that the values of z are always positive, so $z^k$ is always positive, so $z^k+1\geq 1$ for all values of z in $\overline{D}$ . Then,

$\Big| \frac{z^k}{z^k + 1}\Big| \leq z^k,$

because if we make the values of the denominator smaller, the whole fraction becomes larger.

Moreover, as z is in the interval [0,r], we have that $z\leq r$ and as consequence $|z^k|\leq r^k$ . With this in addition to the previous bound we obtain

$\Big| \frac{z^k}{z^k + 1}\Big| \leq |z^k|\leq r^k.$

With this, our sequence is $M_k = r^k$ and the corresponding series is $\sum_{k=1}^\infty r^k$ , which is a geometric series with ratio less than 1, hence it is convergent.

Then, as consequence of Weierstrass M-test we have the uniform convergence of the series in the given domain.

Round to the nearest cent when necessary. Which of the following is the best price?

Eva8 [605]

Answer: The Answer Is C.

Step-by-step explanation:

When you divide each of them you will notice that C costs the least.

For choice A when you 5 by 3.25 you will get 0.65.

For choice B when you divide 8 by 6.10 you will get 0.7625

For choice C when you divide 12 by 7 you will get 0.5833.....

For choice D when you divide 10 by 6.44 you will get 0.644.

So when you look at the results you will see that choice C is the best deal.
