Answer:

Recursive formula for geometric sequence

$a_{n}=a_{n-1}\times r$

is $a_{n}=a_{n-1}\times 6$

and explicit formula for geometric sequence $a_{n}=a_{1}^{r-1}$ is

$a_{n}=(\frac{1}{2})^{6-1}$

Step-by-step explanation:

Given sequence is $\frac{1}{2},3,18,108,648,...$

To find the recursive and explicit formula for this sequence:

Let $a_{1}=\frac{1}{2},a_{2}=3,a_{3}=18,a_{4}=108,a_{5}=648,...$

To find the common ratio r:

$r=\frac{a_{2}}{a_{1}}$

$=\frac{3}{\frac{1}{2}}$

$=3\times 2$

$=6$

Therefore r=6

$r=\frac{a_{3}}{a_{2}}$

$=\frac{18}{3}$

$=6$

Therefore r=6

Therefore the common ration r=6

Therefore the given sequence is geometric sequence

Recursive formula for geometric sequence is $a_{n}=a_{n-1}\times r$

$a_{n}=a_{n-1}\times 6$

and explicit formula is $a_{n}=a_{1}^{r-1}$

$a_{n}=(\frac{1}{2})^{6-1}$

$=(\frac{1}{2})^{5}$

$=\frac{1}{32}$

Therefore $a_{n}=\frac{1}{32}$

The six Grade is holding a fundraiser were students will make and sell peace necklaces for $1.50 each each student is responsibl

kap26 [50]

Answer:

$ 584.89

Step-by-step explanation:

so each student is responsible for selling 12 necklaces...and there are 130 students....so thats (130 * 12) = 1560 necklaces

each necklace is 1.50....so thats (1560 * 1.50) = 2340

profit = revenue earned - expenses

profit = 2340 - 0.45 = 2339.55

1/4 of the profit goes to Puerto Rico

1/4 * 2339.55 = 2339.55/4 = 584.887 rounds to $ 584.89 <==
