Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
The technique of matrix isolation involves condensing the substance to be studied with a large excess of inert gas (usually argon or nitrogen) at low temperature to form a rigid solid (the matrix). The early development of matrix isolation spectroscopy was directed primarily to the study of unstable molecules and free radicals. The ability to stabilise reactive species by trapping them in a rigid cage, thus inhibiting intermolecular interaction, is an important feature of matrix isolation. The low temperatures (typically 4-20K) also prevent the occurrence of any process with an activation energy of more than a few kJ mol-1. Apart from the stabilisation of reactive species, matrix isolation affords a number of advantages over more conventional spectroscopic techniques. The isolation of monomelic solute molecules in an inert environment reduces intermolecular interactions, resulting in a sharpening of the solute absorption compared with other condensed phases. The effect is, of course, particularly dramatic for substances that engage in hydrogen bonding. Although the technique was developed to inhibit intermolecular interactions, it has also proved of great value in studying these interactions in molecular complexes formed in matrices at higher concentrations than those required for true isolation.
B, Rate because the percent is basically the rate they mark up the quantity or whatever it is applied to. :)
Step-by-step explanation:
If you recall SOH CAH TOA, you know that
cosine ∠T = adjacent / hypotenuse
You can write this with adjacent = OT and hypotenuse = BT.
And you can also write this with adjacent = AT and hypotenuse = CT.
So cosine ∠T = OT/BT = AT/CT.
But this is not exactly what has to be proven. If we multiply left and right by BT/AT we do get what we want:
OT/AT = BT/CT
which IS what had to be proven.

Im sure the 252 means the days.
