So what will it be a percentage of? it will be the percentage of the original recruits, of the original 150.
for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%:

so the number of trainees decreased by 20 %
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
By looking at the degree of the polynomials, we conclude that the option that is not linear is option C.
<h3>Which of the following functions is not a linear function?</h3>
A polynomial is an expression of the form:

Where all the exponents are natural numbers.
We define the degree of a polynomial as the largest exponent, and we define a linear function as a polynomial of degree 1.
So a linear function is of the form:

Now, if you look at option C, you can see that the degree of that polynomial is 2. So that is not a linear function.
Then the correct option is C.
