The image is the set of all points in $\mathbb{R}^4$ that you get by multiplying this matrix to points in $\mathbb{R}^5$, you can find these by checking the matrix on the standard basis. The kernel is the set of all points in $\mathbb{R}^5$ such that, multiplying this matrix with them gives the zero vector.
These seven companies alone have produced almost one-fifth (18.7 percent) of all industrial carbon released into the atmosphere since the dawn of the Industrial Revolution.
Activated carbons are different because of the starting material and manufacturing methods. These raw. materials establish the general characterizes, and differences will exist in the finished product. Domestically most carbons are manufactured from coals. The base raw material and pretreatment steps. prior to activation can affect many of the physical and activity characteristics of activated carbon.
