serious [3.7K]

Answer:

Step-by-step explanation:

The surface area of a sphere (which the earth is considered to be) = 4 pi r^2

pi = 3.14

r = 6340

Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.

The best recruitment source, that is, one which tends to result in attracting employees who experience greater loyalty, tenure,
Anna11 [10]

Answer:

The best recruitment source, that is, one which tends to result in attracting employees who experience greater loyalty, tenure, and job satisfaction than other recruiting sources,is **referrals from current employees**

Step-by-step explanation:

This is an HR question.

Referrals given to potential employees by current employees refer to the glowing references about the firm provided by those current employees to the potential employees.

The best set of people to talk about work conditions, pay, etc., at a workplace are the actual workers of that workplace.

Whenever they provide such privy information to a potential employee, it leaves no massive room for unpleasant surprises when the potential employee takes the job. The referrals basically groin the employee for the the best and the worst of such a workplace, that even qualified personnel, before taking up jobs, like to speak to current employees of that firm.

In HR, there's the popular saying that a firm is as good as the way they treat their employees.

So, such total information before taking a job leads to gaining employees that know all about what to expect and which realistic job satisfaction to target. Their realities after starting the job is often already calculated.

Hence, anyone that interacts with current employees of a firm and still takes up job with the firm, has a huge tendency to stay longer, be more loyal and have a bigger job satisfaction.

Hope this Helps!!!

How much smaller is the sum of the first 1000 natural numbers than the sum of the first 1001 natural numbers?
aleksandr82 [10.1K]

ANSWER

1001

EXPLANATION

The sum of the first n - natural numbers is

S_n=  \frac{n}{2} (2a + d(n - 1))

The sum of the first 1000 terms is

S_{1000}=  \frac{1000}{2} (2(1) + 1(1000 - 1))

S_{1000}=500 (1001)

S_{1000}=500500

The sum of the first 1001 terms is

S_{1001}=  \frac{1001}{2} (2(1) + 1(1001 - 1))

S_{1001}= 1001 \times (501)

= 501501

The difference is

501501 - 500500= 1001
