Answer: f(x)=567(1/3)^x
Step-by-step explanation:  
At x = 0   y = 567
at x = 1   y = 567 - 567(1/3)
at x = 2   y = 567 - 567(1/3)(1/3)
at x = 3   y = 567 - 567(1/3)(1/3)(1/3
 
        
             
        
        
        
y = 25x + 50
$50 is a constant, whereas $25 is the daily rate and will vary
let x be the number of days rented, then
y = 25x + 50 ← in slope-intercept form
 
        
                    
             
        
        
        
It represents the amount you'll spend all together on one pound of oranges and one pound of apples.
 
        
                    
             
        
        
        
Answer:
√2 + x
Step-by-step explanation:
To obtain the hypotenus, h:
Using Pythagoras rule :
h² = opposite² + Adjacent²
Opposite = √2
Adjacent= x
h² = (√2)² + x²
Take the square root of both sides
h = √2 + x
Hence, the hypotenus is √2 + x
