Neco Model Questions Vol1 2025 Agricultural Science Question 1
Practice objective / multiple choice question 1 from the 2025 Neco Model Questions Vol1 Agricultural Science examination.
A forest stand of a fast‑growing species has its timber volume (in m³) modelled by \(V(t)=V_0 e^{kt}\), where \(V_0=2000\) m³ is the initial volume and the annual growth rate \(k=0.04\). Each year a constant volume \(C\) (in m³) is harvested. To preserve ecological function the remaining volume after 20 years must be at least 2500 m³. What is the greatest constant annual cut \(C\) that satisfies this condition? Give your answer to one decimal place.
