Answer:
a(8) = -0.0027
Step-by-step explanation:
The most general formula for a geometric sequence is a(n) = a(1)*r^(n-1), where a(1) is the first term and r is the common ratio.
Here, the formula becomes a(n) = 6*(-1/3)^(n-1).
Substitute 8 for n to find the eighth term:
a(8) = 6*(-1/3)^(8-1), or a(8) = 6(-1/3)^7, or a(8) = -0.0027

Answer:
<em>A stack of 4 trillion one dollar bills will be   meters.</em>
 meters.</em>
Step-by-step explanation:
The annual expenditure of the US federal government is approximately 4 trillion dollars.
We know,  1 trillion dollars = 10¹² dollars.
So,  4 trillion dollars  dollars.
 dollars. 
Each one dollar bill is 0.0001 meters thick. 
So, the total height of the stack of 4 trillion one dollar bills will be.....
![[0.0001\times(4\times 10^1^2)]meters\\ \\ =[10^-^4\times(4\times 10^1^2)]meters\\ \\ =(4\times 10^8) meters](https://tex.z-dn.net/?f=%5B0.0001%5Ctimes%284%5Ctimes%2010%5E1%5E2%29%5Dmeters%5C%5C%20%5C%5C%20%3D%5B10%5E-%5E4%5Ctimes%284%5Ctimes%2010%5E1%5E2%29%5Dmeters%5C%5C%20%5C%5C%20%3D%284%5Ctimes%2010%5E8%29%20meters)
 
        
             
        
        
        
Answer:
y = 6/5x - 2
Step-by-step explanation:
y = mx + b
plug in values
4 = (6/5)(5) + b
simplify
4 = 6 + b
subtract 6 from both sides
-2 = b
y = 6/5x - 2
