Mathematics

statuscvo [17]2 years ago
7 0

The first quantum number describes the electron shell, or energy level, of an atom. The value of n ranges from 1 to the shell containing the outermost electron of that atom. For example, in cesium (Cs), the outermost valence electron is in the shell with energy level 6, so an electron in cesium can have an n value from 1 to 6.

Ilya [14]

Answer:

  • Given and explained below.

question 4

using sine rule:

\sf sinx = \frac{opp}{hyp}

\sf sinx = \frac{11}{13}

\sf x = sin^{-1}(\frac{11}{13} )

\sf x = 57.8

question 5

using cosine rule:

\sf cosx =\frac{adj}{hyp}

\sf cos(31) =\frac{x}{17}

\sf cos(31)*17 =x

\sf x = 14.6

Determine whether or not the relation is a function. Please help asap
OLga [1]

Answer:

A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function
