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 =

at x=-3 and y=-1
2(-3+4)^2 - ((3*-1)+5)^3
2 (1)^2 - (2)^3
2 - 8

The answer is 14137.17 because to find the volume of the sphere, the equation is 4/3 times pi times the radius cubed.
