Answer:
Option C
Step-by-step explanation:
Given inequality is,
5x + 38 ≤ 4(2 - 5x)
5x + 38 ≤ 8 - 20x [Distributive property]
5x + 20x + 38 ≤ 8 - 20x + 20x [By adding 20x on both the sides of the inequality]
25x + 38 ≤ 8
(25x + 38) - 38 ≤ 8 - 38 [By subtracting 38 on both the sides of the inequality]
25x ≤ -30
 [Dividing by 25 on both the sides of the inequality]
 [Dividing by 25 on both the sides of the inequality]
x ≤ 1.2
Therefore, Option (C) will be the correct graph.
 
        
             
        
        
        
Answer:
1 to 1 
Step-by-step explanation:
function f in more than one point, then the function is 1 to 1
 
        
             
        
        
        
 is the algebraic representation for an exponential function
 is the algebraic representation for an exponential function
Step-by-step explanation: 
Given:
f(x + 1) = 4.f(x)
f(3) = 16
To Find:
Algebraic representation for an exponential function=?
Solution:
From the formula f(x+n) =  f(x)
 f(x)
when n= 1, x= 3
f(3+1)= 4(1)f(3)
f(4)= 4f(3)
Substituting the value of f(3)
f(4)= 4f(3)
f(4)= 4 x 16  
f(4)= 64
f(4)=
f (5) =  x 16
 x 16
f (5) =  x
 x   
 
f(5)= 
Similarly,
F(6) = 
Hence, 
 
        
             
        
        
        
The volume is 508.94 cm^3
