Answer:
a = -86.
Step-by-step explanation:
By the Factor Theorem, if x + 4 is a factor then P(-4) = 0, so:
P(-4) = 2(-4)^3 - 11(-4)^2 + a(-4)- 40 = 0
-128 - 176 - 4a - 40 = 0
-4a = 128 +176 + 40
-4a = 344
a = -86.
 
        
             
        
        
        
It is exponential growth because it says 18.36% "more than" and it can be linear because it does not stay at a constant rate of change. Answer: Exponential growth

Answer:
 
Step-by-step explanation:
we have that
The scale drawing is 

we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm 

For x=80 cm 

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
  A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or
 or  
For x=40 cm, y=900
substitute
 ----->
 ----->  
 
The equation is 
 
 
        
             
        
        
        
89 would be the correct answer
