The infinite geometric series S=1+( 2/3 )+( 2/3 )^ 2 +( 2/3 )^ 3 .... equal to:

weqwewe [10]

SOLUTION

The question simply means that we should find the sum to infinity of the geometric series.

The formula of sum to infinity of a geometric serie is given by

$S_{\infty}=\frac{a}{1-r}$

Where

$\begin{gathered} S_{\infty}\text{ is the sum to infinity} \\ \\ a\text{ is the first term = 1} \\ \\ r\text{ is the common ratio = }\frac{2}{3} \end{gathered}$

So, this becomes

$\begin{gathered} S_{\infty}=\frac{a}{1-r} \\ \\ S_{\infty}=\frac{1}{1-\frac{2}{3}} \\ \\ S_{\infty}=\frac{1}{\frac{3-2}{3}} \\ \\ S_{\infty}=\frac{1}{\frac{1}{3}} \\ \\ S_{\infty}=3 \end{gathered}$

Therefore, option b is the correct answer

Determine the integer value of n that satisfies the the equation. 4^n=16 3^n=1/81

tresset_1 [31]

Answer:

Step-by-step explanation:

$4^{n} = 16 \\\\4^{n} = 4^2\\\\$

n = 2

$3^{n} =\frac{1}{81}\\\\ = \frac{1}{3^{4}}\\\\3^{n} = 3^{-4}$

n = -4

A stereo is marked down $105. if this is a 25% decrease, find the cost price?

Aneli [31]

Answer:420$
Solution: 105•4= 420$
25%= 1/4 therefore we can find the original price by multiplying the decrease with 4
