n! is called a factorial.

It would look something like this: n! = 1·2·3·...·n

An example:

5! = 1·2·3·4·5 = 120

Which formula can be used to find the nth term of a geometric sequence where the fifth term is 1/6 and the common ratio is 1/4?

OlgaM077 [116]

Answer:

$a_n = 16(\frac{1}{4})^{n - 1}$

Step-by-step explanation:

Given:

Fifth term of a geometric sequence = $\frac{1}{16}$

Common ratio (r) = ¼

Required:

Formula for the nth term of the geometric sequence

Solution:

Step 1: find the first term of the sequence

Formula for nth term of a geometric sequence = $ar^{n - 1}$ , where:

a = first term

r = common ratio = ¼

Thus, we are given the 5th term to be ¹/16, so n here = 5.

Input all these values into the formula to find a, the first term.

$\frac{1}{16} = a*\frac{1}{4}^{5 - 1}$

$\frac{1}{16} = a*\frac{1}{4}^{4}$

$\frac{1}{16} = a*\frac{1}{256}$

$\frac{1}{16} = \frac{a}{256}$

Cross multiply

$1*256 = a*16$

Divide both sides by 16

$\frac{256}{16} = \frac{16a}{16}$

$16 = a$

$a = 16$

Step 2: input the value of a and r to find the nth term formula of the sequence

nth term = $ar^{n - 1}$

nth term = $16*\frac{1}{4}^{n - 1}$

$a_n = 16(\frac{1}{4})^{n - 1}$

The distance Max's bike moves is directly proportional to how many rotations his bike's crank shaft has

Gemiola [76]

Answer:

187.5 feet

Step-by-step explanation:

we know that

Max's bike moves 25 feet after two rotations

using proportion

Find out how many feet will the bike move after 15 rotations

Let

x ----> the distance in feet

$\frac{25}{2}\frac{ft}{rev}=\frac{x}{15}\frac{ft}{rev}\\\\x=15(25)/2\\\\x=187.5\ ft$

como puedes saber con anticipacion el numero de cifras decimales que lleva el resultado de multiplicar un numero natural por un

Oduvanchick [21]

Answer:

The same number as in the multiplier

Step-by-step explanation:

The number of decimal places in the product is the sum of the decimal places in the factors.

A natural number is an integer. It has no decimal places.

So, the product has the product has the same number of decimal places as the multiplier.

For example, 2 × 3.45 = 6.90

The number 3.45 has two decimal places, so the product has two decimal places.
