If n is an integer, then cos(n(2<span>π))=1.

Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...

If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>

As a recruiter, you are asked to recruit 65 new sales associates for an organization. Traditionally, for the organization, 25% o
Lorico [155]

Answer: 1733.33 ≈ 1734 applicants

Step-by-step explanation:

Let x be the number of job applicants being looked at.

If 25% of applicants become job candidates, then number of job candidates = 0.25x

If 20% of job candidates receive job offers, then the number of job offers = 0.20 × 0.25x = 0.05x

If 75% of job offers are accepted, then number of accepted recruits = 0.75 × 0.05x = 0.0375x

This 0.0375x shows the number of new recruits which is equivalent to the 65 that is needed by the client if the recruiter.

By equating this 0.0375x to 65,we have:

0.0375x = 65

x = 65/0.0375

x= 1733.33 applicants, for whole number sake because we're dealing with humans, we approximate to 1734

The fourth root? There is no simplifying to be done.

The only way to continue work on this is converting to decimal. To four places the answer is 3.3437.

If you meant to ask for the cube root, the answer is 5.
