Answer:

$a_8=38$

Step-by-step explanation:

<u>Recursive sequence </u>

In a recursive sequence formula, each term $a_n$ is computed as a function of one or more previous terms. In the formula

$a_n=a_{n-1}+5$

n is the number of the term we want to calculate. If n=8, then the formula becomes

$a_8=a_{7}+5$

We can see $a_{n-1}$ is the previous term. It means we need $a_7$ to be able to compute $a_8$ . But we also need $a_6$ to compute $a_7$ and so on until some known data is reached. The question provides five terms, $a_5=23.$

$a_6=a_5+5=28$

$a_7=a_6+5=33$

$a_8=a_7+5=38$

$a_8=38$

Answer:

After 9 years the account will be worth 13709.60$

Step-by-step explanation:

We are given the following in the question:

We are given the following in the question:

P = $8000

r = 6% = 0.046

n = 12

The compound interest is given by:

$A = p\bigg(1+\dfrac{r}{n}\bigg)^{nt}$

where A is the amount, p is the principal, r is the interest rate, t is the time in years.

Putting the values, we get,

$13709.60 = 8000\bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\dfrac{13709.60}{8000} = \bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\Rightarrow 1.7137 = (1.005)^{12t}\\\Rightarrow t \approx 9$

Thus, after 9 years the account will be worth 13709.60$

2 (3x+1)=17-3 (x-17)

elena-14-01-66 [18.8K]

<h2>Answer:</h2>

$x = \frac{22}{3}$

<h3>alternative form:</h3>

$x = 7 \frac{1}{3} \: or \: x = 7.33333333333$

<h2>Step-by-step explanation:</h2>

$2(3x + 1) = 17 - 3( x - 17) \\ distribute \\ \\ 6x + 2 = 17 - 3x + 51 \\ add \: 3x \: from \: both \: sides \\ \\ 9x + 2 = 17 + 51 \\ add \: 17 \: to \: 51 \\ \\ 9x + 2 = 68 \\ subtract \: 2 \: from \: both \: sides \\ \\ 9x = 66 \\ divide \: both \: sides \: by \: 9 \\ \\ x = \frac{22}{3}$
