Determine the radius of convergence of the following power series. Then test the endpoints to determine the interval of converge
tresset_1 [31]

Answer:

Radius of the convergence is R = \frac{1}{21}

and,

The Interval of convergence is -\frac{1}{21}

Step-by-step explanation:

Given function : Σ(21x)^k

Now,

Using the ratio test, we have

R = \lim_{n \to \infty} |\frac{21x^{k+1}}{21x^{k}}|

or

R = \lim_{n \to \infty} |\frac{21x^{k}\times21x^{1}}{21x^{k}}|

or

R = \lim_{n \to \infty} |21x^{1}|

now,

for convergence R|x| < 1

Therefore,

\lim_{n \to \infty} |21x^{1}| < 1

or

-\frac{1}{21}

and,

Radius of the convergence is R = \frac{1}{21}

and,

The Interval of convergence is -\frac{1}{21}

A set has 62 proper subsets how many elements has it for?<br>​
MrRissso [65]

Answer:

6

Step-by-step explanation:

Total number of subsets is given as

{2}^{n}

But the subset of a set consists of the proper subsets, an empty set and the set itself.

Total number of subsets are 64

Therefore,

{2}^{n}  = 64

{2}^{n}  =  {2}^{6}

Comparing both sides

n = 6

(4, -3), (x, 1); slope -4
Alexandra [31]

Answer:

x = 3

Step-by-step explanation:

m =  \frac{y \frac{}{2}  - y \frac{}{1} }{x \frac{}{2}  - x \frac{}{1} }

m = slope

x, y = coordinates

- 4 =  \frac{1 - ( - 3)}{x - 4} \\  - 4(x - 4)   = 1 + 3 \\  - 4x  + 16 = 4 \\  - 4 x = 4 - 16 \\  - 4x =  - 12 \\  x=  \frac{ - 12}{ - 4}  \\ x = 3
