Answer: the rectangle of maximum area is a square of side length 1= 4 cm let x and y be the lengths of the sides of the rectangle measured in cm 
Step-by-step explanation:
then the perimeter is 
2x+2y=16
so that:
y=8- x
 
        
             
        
        
        
The answer is 3 days. My work is in the pic in case you need it
 
        
             
        
        
        
Y intercept is (0,3)
Slope is 3/2
        
             
        
        
        
Answer:
k = 
Step-by-step explanation:
Fisherman noticed a stretch in the spring = 'b' centimetres
Weight of the fish = a kilograms
If force applied on a spring scale makes a stretch in the spring then Hook's law for the force applied is,
F = kΔx
Where k = spring constant
Δx = stretch in the spring
F = weight applied
F = mg
Here 'm' = mass of the fish
g = gravitational constant
F = a(9.8)
   = 9.8a
Δx = b centimetres = 0.01b meters
Therefore, 9.8a = k(0.01b)
k =  
 
k = 
Therefore, spring constant of the spring will be determined by the expression, k =
