Neco Model Questions Vol1 2022 Agricultural Science Question 23
Practice objective / multiple choice question 23 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
A grain store can be kept at any integer temperature between 5 °C and 25 °C. The monthly loss of grain due to respiration is modelled by \(R(T)=200\,e^{-0.05T}\) kg, and the monthly loss due to insect infestation is \(I(T)=\begin{cases}0,& T\le10\\150\bigl(1-e^{-0.1(T-10)}\bigr),& T>10\end{cases}\) kg. The grain will be stored for six months. Determine the integer temperature that minimises the total loss over the storage period and state the minimum total loss (rounded to the nearest kilogram).
