Answer:
d forms a proportion
Step-by-step explanation:
3x5=15,4×5=20
so they both increase protionally 
therefore they are protional
 
        
                    
             
        
        
        
Answer:  The change represents  growth with 89% of growth rate.
Step-by-step explanation:
The exponential function is given by :-
 ... (i)
... (i)
Where , A = initial value , b= multiplicative factor and  x= time period
- We call 'b' growth factor when b>1, we can write b= 1+r , where r is the rate of growth.
- We call 'b' decay factor when b<1 , we can write b= 1-r , where r is the rate of decay.
The given function :  .
.
By comparing this to (i) , we get
b= 1.89 > 1 , thus it represent the growth.
Also,
 
i.e. Percentage rate of growth = 0.89 x 100 = 89%.
 
        
             
        
        
        
Answer:
your answer is A. 92.4
Step-by-step explanation:
Diagonal Length = v(92.4² + 50²)
V(8537.76 + 2500)
V(1037:76)
Diagonal Length 105
 
        
                    
             
        
        
        
The would get a 60%. To find this you need to divide 18/30.
