What is the value of r of the geometric series n=11.3(0.8)n-1

jeyben [28]

the value of r of the geometric series n=11.3(0.8)n-1

$an=11.3(0.8)^{n-1}$

General formula for nth term of any geometric series is $a_n=a_1(r)^{n-1}$

Here 'r' is the common ratio

a_1 is the first term of the series

Now we compare the given formula with general formula

Compare $an=11.3(0.8)^{n-1}$ with $a_n=a_1(r)^{n-1}$

The value of r= 0.8

victus00 [196]

Answer:

75% of the votes were in favor.

Step-by-step explanation:

To find the percent(rate), we use the formula r=p/b

The question is "What percent(rate) of 56 is 42?"

So fill in the formula and it will show as r=42/56, which is the rate will be equal to 42 divided by 56.

Perform the calculations and the result will show 0.75

Convert the decimal to a percent by moving the decimal point two places to the right and you will have 75% as your answer.

If 10-10ˣ=9.9, find x

madam [21]

we are given

$10-10^x=9.9$

we can move 10 on right side

$-10^x=9.9-10$

$-10^x=-0.1$

we cancel -1

$10^x=0.1$

we can rewrite right side

$10^x=10^{-1}$

we can compare exponents

and we get

$x=-1$ .............Answer
