Answer:

1. 23

2. 8

Step-by-step explanation:

☆Cross multiply.

$\frac{2}{10} = \frac{4}{a - 3} \\ \\ 40 = 2(a - 3) \\ 40 = 2a - 6 \\ \frac{ + 6 = \: \: \: \: \: \: \: \: + 6}{ \frac{46}{2} = \frac{2a}{2} } \\ \\ 23 = a$

--------

$\frac{k}{6} = \frac{4}{3} \\ \\ \frac{24}{ 3} = \frac{3k}{3} \\ \\ 8 = k$

PLEASE HELP PLEASE WILL GIVE BRAINLIEST!!!!!!! A retain arithmetic sequence has the following explicit formula for the nth term:

SashulF [63]

In the given question,the given explicit formula is

$a_{n) = 4+(n-1)(7)$

Which is of the form

$a_{n} = a +(n-1)(d)$

So the constant difference is 7 here.

Now for the recursive formula

To find the next term, we need to add 7 to the current term, that is

$a_{n} = a_{n-1} +7$

So the correct option is B

Give the exact form and decimal form of the equation

Svet_ta [14]

Answer:

Exact form: $\sin{(6x)} = \frac{8}{9}$

Decimal form: $\sin{(6x)} = 0.8889$

The solution for x is: The solution for x is of 10.455º

Step-by-step explanation:

We are given the following equation:

$8 = 9\sin{(6x)}$

Placing into the desired format, the exact format is:

$\sin{(6x)} = \frac{8}{9}$

In the decimal part, we divide 8 by 9. So

$\sin{(6x)} = 0.8889$

Solving for x:

We apply the inverse sine. So

$\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}$

$6x = 62.73$

$x = \frac{62.73}{6}$

$x = 10.455$

The solution for x is of 10.455º
