Step-by-step explanation:

#1) $\arcsin \left(0.64958\right)=0.70703\dots \quad \begin{pmatrix}\mathrm{Degrees:}&40.51^{\circ \:}\end{pmatrix}$

∡C =62.49

$\frac{\left(\sin \left(27^{\circ \:}\right)\right)}{3}=\frac{\sin \left(54^{\circ \:}\right)}{x}\quad :\quad x=\frac{3\left(\sqrt{5}+1\right)}{\sin \left(27^{\circ \:}\right)\cdot \:4}\quad \left(\mathrm{Decimal}:\quad x=5.34603\dots \right)$

Please check the explanation.

Step-by-step explanation:

Given the relation

{(0,4), (-4,-4), (-2,3), (4,0)}

Determining the table:

x y

0 4

-4 -4

-2 3

4 0

Mapping

X Y

0 → 4

-4 → -4

-2 → 3

4 → 0

It is clear from the table and mapping that the given relation is a function because each input has exactly one output.

In other words, the given relation is a function because there is no duplicated or repeated x-value.

The graph is also attached below.

Determining the domain

We also know that the domain is the set of all the first elements or members of ordered-pairs.

First elements are also termed as x-coordinates.

Thus, the domain of the function in ascending order.

Domain: {-4, -4, 0, 4}

Determining the range

We also know that the domain is the set of all the second-elements or members of ordered-pairs.

The second-elements are also termed as y-coordinates.

Thus, the range of the function in ascending order.

Domain: {-4, 0, 3, 4}

Express each relation is a table, a graph, and mapping. Then determine the domain and range. 2. {(0,
