Mathematics
1 answer:
Nataly_w [17]3 years ago
8 0

Answer:

  a. −x2

  c. −5x^6+10x^5−3x^2+9

Step-by-step explanation:

The signs of the end values of f(x) are the same, so the polynomial is of even degree. (Eliminates choice E.) The signs are both negative, so the leading coefficient of the polynomial is negative. (Eliminates choices B and D.)

The appropriate choices are ...

  A: 2nd degree with negative leading coefficient

  C: 6th degree with negative leading coefficient

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 2y = x + 2 x - 3y= -5 O A. (2, 2)
Darya [45]

Answer:

(4,3)

Step-by-step explanation:

2y = x + 2

x - 3y = -5

Rearrange the second equation to equal y.

x - 3y = -5

x + 5 = 3y

(x+5)/3 = y

Substitute into the first equation.

2y = x +2

2[(x+5)/3] = x + 2

(2x + 10)/3 = x + 2

2x + 10 = 3(x + 2)

2x + 10 = 3x + 6

10 - 6 = 3x - 2x

4 = x

Therefore, the correct ordered pair is (4,3) since x is equal to 4.

Determine between which consecutive integers the real zeros of f(x) = 2x - 5x+1 are located.
LuckyWell [14K]

Answer:

between 0&1 and 2&3

Step-by-step explanation:

(Assuming that f(x) = 2x^2 - 5x + 1)

To solve this question we just need to find the zeros of the function f(x), and we do that by making f(x) = 0 and finding the values of x:

2x^2 - 5x + 1 = 0

Now we can use Bhaskara's formula:

Delta = b^2 - 4ac = 25 - 4*2 = 17

sqrt(Delta) = 4.12

x1 = (5 + 4.12) / 4 = 2.28

x2 = (5 - 4.12) / 4 = 0.22

the zero x1 = 2.28 is between 2 and 3, and the zero x2 = 0.22 is between 0 and 1, so the answer is 'between 0&1 and 2&3'

As the options A, B, C and D are not clear in the question text, you can just mark the option that has this result.

sergij07 [2.7K]

Answer:

1368 dollars.

Step-by-step explanation:

given that Jack s purchasing a stock that pays an annual dividend of $3.42 per share

No of shares Jack purchased = 400

Price per share = 53.18$

Amount invested by Jack in shares = 400*53.18 =21272 dollars

Annual dividend = 3.42 per share

Total dividend = 400*3.42 = 1368

Annual income from dividends = 1368 $
