If x^2=20 what is the value of x will give brainliest for answer
Schach [20]

Answer:

x² - 20 = 0

Using the quadratic formula

x =  \frac{ - b± \sqrt{( {b})^{2} - 4ac } }{2a}

a = 1 b = 0 c = -20

So we have

x =  \frac{ - 0 ±  \sqrt{ {0}^{2}  - 4(1)( -20)} }{2(1)}  \\  \\ x =  \frac{± \sqrt{80} }{2}  \\  \\ x =  \frac{±4 \sqrt{5} }{2}  \\  \\  \\ x = ±2 \sqrt{5}  \\  \\  \\ x = 2 \sqrt{5}  \:  \:  \: or \:  \:  \: x =  - 2 \sqrt{5}

Hope this helps you.

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}
