Compute the product using (a) the definition where Ax is the linear combination of the columns of A using the corresponding entries in x as weights, and (b) the row-vector rule for computing Ax. If a product is undefined, explain why. Set up the linear combination of the columns of A using the corresponding entries in x as weights. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (Type the factors and terms of your expression with the column matrices in the same order as they appear in the original matrix. In each term, type first the coefficient and then the column matrix.) The matrix-vector Ax is not defined because the number of columns in matrix A does not match the number of entries in the vector x. The matrix-vector Ax is not defined because the number of rows in matrix A does not match the number of entries in the vector x.

the solution is h=10 because you add 9 to each side of the equation.

the answer to this question is yes

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
