Answer:
= - 4![(4)^{n-1}](https://tex.z-dn.net/?f=%284%29%5E%7Bn-1%7D)
Step-by-step explanation:
Note the common ratio r between consecutive terms in the sequence, that is
- 16 ÷ - 4 = - 64 ÷ - 16 = - 256 ÷ - 64 = 4
This indicates the sequence is geometric with n th term ( explicit formula )
= a![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Here a = - 4 and r = 4, thus
= - 4
← explicit formula
The area will be
2500(1-5.25/100)^15
=1113km2 (nearest square kilometer)
Answer:
Step-by-step explanation:
Sales revenue x (100%+sales tax rate) = total sales including tax
sales revenue x 1.085 (100% + 8.5%) = 78120
sales revenue = 78120/1.085
sales revenue = 72000
total sales including tax - sales revenue = sales tax
78120 = 72000 = 6120
Journal entry:
cash. 78120
Sales revenue. 72000
Sales tax payable. 6120
I believe c is the correct answer correct me if I'm wrong
