Find all values of x for which the series converges. (enter your answer using interval notation. ) [infinity] (4x)n n = 1
andreyandreev [35.5K]

The series converges to  1/(1-9x) for -1/9<x<1/9                  

Given the series is  ∑ 9x^{n} x^{n}

We have to find the values of x for which the series converges.

We know,                

∑ ar^{n-1}    converges to  (a) / (1-r) if r < 1

Otherwise the series will diverge.

Here, ∑ (9x)^{n} is a geometric series with |r| = | 9x |

And it converges for |9x| < 1

Hence, the given series gets converge for -1/9<x<1/9

And geometric series converges to a/(1-r)

Here, a = 1 and r = 9x

Therefore, a/(1-r) = 1/(1-9x)

Hence, the given series converges to   1/1-9x  for  -1/9<x<1/9

Convert 1/15 into a decimal correct to 2 decimal places ​
Citrus2011 [14]

Answer:

\frac{1}{15} = 0.\overline{66}

Step-by-step explanation:

We proceed to show the procedure to calculate the given fraction into a decimal form:

1) Since numerator is less than denominator, the integer component of the decimal number is zero:

\frac{1}{15} = 0.xx

2) We multiply the numerator by 10 and find the tenth digit:

\frac{10}{15} = 0

Then,

\frac{1}{15} = 0.0xx

3) We multiply the fraction in 2) by 10 and find the hundredth digit:

\frac{100}{15} = 6

Then,

\frac{1}{15} = 0.66x

And the remainder is:

r = 100-15\times 6

r = 10

4) We multiply the remainder by 10 and divide this result by the denominator to determine the thousandth digit:

\frac{100}{15} = 6

Then,

\frac{1}{15} = 0.666

This question asks us to write a decimal correct to 2 decimal places, which has the characteristic that is infinite periodical decimal. Then, the result correct to 2 decimal places is:

\frac{1}{15} = 0.\overline{66}

Simplify C^5 x c<br> Plz can someone figure it out cuz I don’t get it
Fofino [41]

Answer:

c^6

Step-by-step explanation:

So, c is the same as c^ 1 ... therefore

c^5 x c

= c^5 x c^1

When we multiply two numbers with same base and different exponent, we add the exponents which in this case as 5 and 1

So c^5 x c^1

= c^(5+1)

= c^6

This is the simplest form
