A = L * W
A = 80
L = 5W
80 = W(5W)
80 = 5W^2
80/5 = W^2
16 = W^2
sqrt 16 = W
4 = W <=== width is 4 ft
L = 5W
L = 5(4)
L = 20 <=== length is 20 ft
        
             
        
        
        
Answer:
$13087.92
Step-by-step explanation:
formula: ab^x
a= starting  amount
a= 5072
b= 1+r
r=rate
r=9%=0.09
b=1+0.09 =1.09
x= 11 (years)
account after 11 years:
= 5072(1.09)^11
=13087.9227277
= 13087.92
 
        
             
        
        
        
As the symmetry of axis is x=6, the mirror point of (2,8) will be (10,8)
        
             
        
        
        
Answer:
x ≥-1
Step-by-step explanation:
 -1/2x -3 ≤ -2.5
Add 3 to each side
 -1/2x -3+3 ≤ -2.5+3
-1/2x ≤ .5
Multiply each side by -2, remembering to flip the inequality
-2 * -1/2x ≥ 1/2 * -2
x ≥-1
