The sum of 30 times (1/3)^(n-1) from 1 to infinity

sergeinik [125]

Let

$S_n=\displaystyle1+\frac13+\frac1{3^2}+\cdots+\frac1{3^n}$

Then

$\dfrac13S_n=\displaystyle\frac13+\frac1{3^2}+\frac1{3^3}+\cdots+\frac1{3^{n+1}}$

and

$S_n-\dfrac13S_n=\dfrac23S_n=1-\dfrac1{3^{n+1}}\implies S_n=\dfrac32-\dfrac1{2\cdot3^n}$

and as $n\to\infty$ , we end up with

$\displaystyle\lim_{n\to\infty}S_n=\lim_{n\to\infty}\sum_{i=1}^{n+1}\frac1{3^{i-1}}=\lim_{n\to\infty}\left(\frac32-\frac1{2\cdot3^n}\right)=\frac32$

So we have

$\displaystyle\sum_{n=1}^\infty30\left(\frac13\right)^{n-1}=30\cdot\frac32=45$

2.) Find the length of the unknown side. Round your answer to the nearest tenth.

Juli2301 [7.4K]

Answer:

14.1

Step-by-step explanation:

Hey There!

This is a right triangle so we have to use the Pythagorean Theorem to solve for the missing side

given the hypotenuse and a leg we do

$hypotenuse^2-given.leg^2$

$15^2-5^2=?^2\\15^2=225\\5^2=25\\225-25=200\\\sqrt{200} =14.1421356$

then we just round to the nearest tenth and get that

?=14.1
