If possible, find a matrix b such that ab = a2 + 2a.

Matrices is an array of numbers, usually 2 dimensional, but can be single dimensional too.

A matrix B such that is given as

(Assuming A is left invertible and  )

Suppose that there is an equation

We cannot always say that

If we assume that A is left invertible, then only we can surely say that we have got

Similarly, for to imply  , we need A to be right invertible.

Assuming that we have A as a left invertible matrix, say

and be its left inverse, then ( is identity matrix)

Then,

Thus, i

A matrix B such that is given as

(Assuming A is left invertible and  )

Step-by-step explanation:

It's possible if dimensions of a matrix A and matrix B are n × n

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
