Is choosing 5 players to represent the team at a fundraiser a permutation or a combination?

1 answer:

3 0

A permutation, since once you choose one member to be in the team, that same person cannot be chosen again. A combination requires us to be able to freely choose the same item in a set as many times as we may wish. A permutation restricts the amount of times we can choose an item in a set.

What are the domain and range of the algebraic function you found by graphing the equation y = 36 – 3x? Please hurry I'm being t

Answer:

Domain $=(-\infty,\ \infty)$

Range $=(-\infty,\ \infty)$

Step-by-step explanation:

Domain : Domain of a function $f(x)$ is the set of all possible values of $x$ for which $f(x)$ exists.

Range : range of a function $f(x)$ is the set of all possible values of $f(x)$ .

Here $f(x)=36-3x$

$x$ can be any value from $-\infty$ to $\infty$ .

$\forall\ x=a\ there\ exists\ f(x)\ such\ that\ f(a)=36-3a$

hence possible value of $x$ can be any value between $-\infty$ and $\infty$

$domain =(-\infty,\ \infty)$

let $y=-f(x)$

$y=36-3x\\3x=36-y\\\\\\x=\frac{36-y}{3}\\$

so $\forall\ f(x)=y\ there\ exist\ x\ \in(-\infty,\ \infty)$ .

hence $f(x)$ can have any value between $-\infty\ to\ \infty.$ .

Range $=(-\infty,\ \infty)$

The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.
