Giant pandas are a vulnerable species famous for their consumption of large amounts of bamboo. Suppose we track the female population of a group of pandas year-to-year, and classify the pandas into three categories: cubs, subadults and adults. Say that u1 (t) denotes the amount of cubs in year t, ug(t) denotes the amount of subadults in year t and uz(t) denotes the amount of adults in year t. Assume the following about the population of pandas: • Cubs remain cubs for only one year - they have a mortality rate of 15% and the rest become subadults; • Approximately 25% of subadults mature to adults each year, approximately 20% of subadults die year year, and the rest remain in this classification; • On average, adults give birth to 0.5 new cubs each year; • 95% of adults survive from one year to the next. We can model the change in class structure each year using the model, u(t + 1) = Aü(t) where u(t) u2 (t) | and A is u3 (t) Number Number Number Number Number Number Number Number Number

Can someone please help with question 12a. Will give thumbs up 

Giant pandas are a vulnerable species famous for their consumption of large amounts of bamboo. Suppose we track the female population of a group of
pandas year-to-year, and classify the pandas into three categories: cubs, subadults and adults. Say that u1 (t) denotes the amount of cubs in year t, u2 (t)
denotes the amount of subadults in year t and uz (t) denotes the amount of adults in year t. Assume the following about the population of pandas:
• Cubs remain cubs for only one year - they have a mortality rate of 15% and the rest become subadults%3;
Approximately 25% of subadults mature to adults each year, approximately 20% of subadults die year year, and the rest remain in this classification;
• On average, adults give birth to 0.5 new cubs each year;
• 95% of adults survive from one year to the next.
We can model the change in class structure each year using the model,
ú(t + 1) = Aú(t)
[u1(t)
u2 (t) | and A is
u3 (t) ]
where u(t)
