Two or zero expresses the possible number of positive real solutions for the given polynomial equation.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equation:

$x^{3}-4 x^{2}-7 x+28=0$

First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero. We can also write the above expression as

$(x-4) \times\left(x^{2}-7\right)=0$

We know the formula, $a^{2}-b^{2}=(a+b)(a-b)$ , make use of this, we get

$(x-4) \times(x-\sqrt{7}) \times(x+\sqrt{7})=0$

So, $x=4, \sqrt{7},-\sqrt{7}$

Hence, from the above expression, we have three values of x as x= 4, 2.64 and -2.64

Simora [160]

Answer:

241 clients

Step-by-step explanation:

His problem can be solved using the principle of proportionality or rule three.

We can take advantage of the proportion between respondents who tell us the number of respondents and how many expect to go on vacation and the total number of workers, therefore:

Respondents /// Whole company

Vacations 21 x

Total 45 516

then x equals:

x = (516 * 21) / (45)

x = 240.8

x = 241 clients

This means that approximately 241 clients expect to go on vacation throughout the company.
