It is a geometric mean sequence.
the 2nd term is 20, the 5th term is 0.16
so the next 3 terms are found by multiplying successive terms by the constant x.  20x^3 = 0.16 which is derived by multiplying 20 by x, three times to get 0.16
So x^3 =.008
x=0.2
The first term is found by saying a1^.2 = 20, so a1 = 100
When n =  1     2   3   4    5
     t(n) = 100 , 20, 4, .8, .16
        
             
        
        
        
Based on your plot points, the best answer seems to be B) $5.00 
        
                    
             
        
        
        
Answer:
1. x = 7
2. x = -5
Step-by-step explanation:
1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 2*x+5*(6*x-9)-(179)=0 
Pull out like factors  6x - 9  =   3 • (2x - 3) 
  (2x +  15 • (2x - 3)) -  179  = 0 
Pull out like factors: 32x - 224  =   32 • (x - 7) 
Solve: x-7 = 0 
Add  7  to both sides of the equation  = 7
2. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -40-(6*x-5*(-4*x-18))=0 
Pull out like factors: -4x - 18  =   -2 • (2x + 9) 
  -40 -  (6x -  -10 • (2x + 9))  = 0 
Pull out like factors:  -26x - 130  =   -26 • (x + 5) 
-26 • (x + 5)  = 0 
 Solve: x+5 = 0 
Subtract  5  from both sides of the equation: x = -5

Answer:
slope = -3
y-intercept = -2
Step-by-step explanation:
y = mx + <em>b</em>
m = slope; <em>b</em> = y-intercept
y= -3x <em>- 2</em>
m = -3 = slope
<em>b = -2 = y-intercept</em>
 
        
                    
             
        
        
        
Answer:
C=100.5 inches
Step-by-step explanation:
Circumference=2πr where r=16 inches
C=2(3.14)(16)
C=100.5 inches
