Answer:
The formula which can be used to describe the sequence is:
⇒ 3rd answer
Step-by-step explanation:
The terms of the sequence are -81, 108, -144, 192, ...
∵ 108 ÷ -81 =
∵ -144 ÷ 108 =
∵ 192 ÷ -144 =
- There is a constant ratio between each two consecutive terms
∴ The sequence is a geometric sequence
The formula of the nth term of the geometric sequence is , where a is the first term and r is the constant ratio between each two consecutive terms
∵ The first term is -81
∴ a = -81
∵ The constant ratio =
∴ r =
- Substitute then in the formula above
∴
Assume that = f(x)
∴ n = x
∴
The formula which can be used to describe the sequence is:

Answer:
the answer to your question is x>-20 , I hope this helps :)
If there are 4 quarts in every gallon, 56 x 4 = 224
So there are 224 quarts in 56 gallons
I hope that helps!
Answer:
so when looking at the tax minus the cost
100%/x%=80500/1932
(100/x)*x=(80500/1932)*x
100=41.666666666667*x
100/41.666666666667 or 6 infinite will get us
2.4=x
x=2.4
so times 2.4% with every cost to see it it matches the tax given!
A is incorrect
it equals 1632
B is not correct as it equals 2208
C is incorrect as it equals 1800 dollars in tax
<em>D is CORRECT as it has the same number in Tax</em>
<em>2040</em>
