A is a 3x3 matrix with det(A) = 4. Find det(adj(A)).
1 answer:
Answer:
The value of det(adj(A)) is 16.
Step-by-step explanation:
It is given that A is a 3x3 matrix with det(A) = 4.
We need to find the value of det(adj(A)).
We have a formula
where, n is order of the square matrix.
Substitute det(A) = 4 and n=3 in the above formula.
Therefore, the value of det(adj(A)) is 16.

Answer: The required function is,
Step-by-step explanation:
Since, the population which is increasing with the constant factor is,
Where, a is the initial population,
b is the growth factor per period,
x is the number of periods.
Here, the given function that represents the mosquito population after x years,
Where, 7 is the growth factor per year,
Since, 12 months = 1 year,
2 month = 1/6 year.
Also, we can write,
Which is the required equivalent function that shows the population of mosquito is increasing in every 2 month by the growth factor .
