Answer:

Step-by-step explanation:
<u><em>Using Pythagorean Theorem:</em></u>
=> 
Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)
=> 
=> 
=> 
Taking sqrt on both sides
=> c = 5.7 units
A function can be represented on a table and on a graph.
The models of the linear relationship between f(x) and x are:

The given parameters are:


So, the function that models the linear relationship is:

Substitute known values

Evaluate all products

Rewrite as:

By comparing the above function to the list of options, we have the true options to be:
