Final answer:
The von Bertalanffy's equation for the growth of a fish can be solved by separating variables and integrating both sides. The specific solution can be found using the initial condition.
Step-by-step explanation:
The von Bertalanffy's equation for the growth of a fish is given by dL/dt = k(24 - L(t)). To solve this differential equation, we can separate variables and integrate both sides.
Starting with dL = k(24 - L(t))dt, we can rearrange and divide both sides by (24 - L(t)) to get 1/(24 - L(t)) dL = kdt.
Integrating both sides gives us the equation ln|24 - L(t)| = kt + C, where C is the constant of integration. Using the initial condition L(0) = 6, we can solve for C and find the specific solution.
