Answer:

$z = \frac{47}{7} = 6 \frac{5}{7}$

Step-by-step explanation:

$7 = \frac{40}{z - 1} \\ 7(z - 1) = 40 \\ 7z - 7 = 40 \\ 7z = 40 + 7 \\ 7z = 47 \\$

$\boxed{\bold{Answer:{\boxed{\green{\bold{z = \frac{47}{7} = 6 \frac{5}{7}}}}}}}$

Answer:

z = 5

Step-by-step explanation:

7=40/z-1

- Add 1 to both sides.

8 = 40/z

- Multiply z to both sides.

8(z) = 40/z (z)

8z = 40

z = 5

Given a geometric sequence in the table below, create the explicit formula and list any restrictions to the domain.

weeeeeb [17]

Answer:

Step-by-step explanation:

given the first 3 terms of the geometric sequence - 4, 20, - 100

with r = $\frac{-100}{20}$ = $\frac{20}{-4}$ = - 5

the n th term formula ( explicit formula ) is

$a_{n}$ = $a_{1}$ $r^{n-1}$

here r = - 5 and $a_{1}$ = - 4, hence

$a_{n}$ = - 4 $(-5)^{n-1}$ with n ≥ 1
