A nonzero polynomial with rational coefficients has all of the numbers [1 sqrt{2}, ; 2 sqrt{3}, ;3 sqrt{4},; dots, ;1000 sqrt{10
Colt1911 [192]

Answer:

Its degree can be at least 1970

Step-by-step explanation:

for each root of the form √q, where q is not a square, we have a root -√q. Therefore, we need to find, among the numbers below to 1000, how many sqaures there are.

Since √1000 = 31.6, we have a total of 30 squares:

2², 3², 4², ...., 30², 31²

Each square gives one root and the non squares (there are 1000-30 = 970 of them) gives 2 roots (one for them and one for the opposite). Hence the smallest degree a rational polynomial can have is

970*2 + 30 = 1970

How to factor 5m2-29m+20?
ser-zykov [4K]

Question :

5m^2 - 29m + 20

Steps:

What can u factor to get 20?

you can make 5 and 4 to make 20 so,..

1. Break it into groups

(5m^2 - 4m) + (-25m + 20)

*Factor out m from (5m^2 - 4m) : m(5m - 4)

*Factor out -5 from (-25m + 20) : -5(5m - 4)

2. Then, you can factor out the common term : (5m - 4) because they both have it. And then u would move the m by the -5 so,...

= (5m - 4)(m - 5) <======= <em>Answer</em>


Hope this helped!!!

An employer with 500 employees gives out gives out 120 surveys but receives only 90 surveys completed by the employees. What are
leva [86]

Answer:

Population 120 given the survey, sample 90 who answered the survey.

Step-by-step explanation:

The entire amount of employees who even received the surveys at all was 120. Because the total number was 120, 120 is the population.

Only 90 out of 120 surveys were received, so 90 is the sample because it is part of 120.

Hope this helps :)
