The potential roots of the function are, 
And the accurate root is 3 it can be determined by using rules of the rational root equation.
<h2>Given that,</h2>
Function; 
<h3>We have to
determine,</h3>
Which of the values shown are potential roots of the given equation?
<h3>
According to the
question,</h3>
Potential roots of the polynomial are all possible roots of f(x).

Using rational root theorem test. We will find all the possible or potential roots of the polynomial.


The factor of the term 45 are,

And The factor of 3 are,

All the possible roots are,

Now check for all the rational roots which are possible for the given function,

Therefore, x = 3 is the potential root of the given function.
Hence, The potential roots of the function are,
.

Answer:
1.9 years
Step-by-step explanation:
There are 365 days in a year
694.44 / 365 = 1.9
Hope this helps!
You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get

Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1

<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1

Thus you must travel at 42 mph for 4 hours
