Answer:
28/9
Step-by-step explanation:
If the roots are J and K, then:
3 (x − J) (x − K) = 0
3 (x² − (J+K)x + JK) = 0
So if we factor out the leading coefficient:
3x² − 2x − 4 = 0
3(x² − 2/3x − 4/3) = 0
The coefficient of the second term is the sum of the roots:
J + K = 2/3
And the constant is the product of the roots:
JK = -4/3
If we take the sum of the roots and square it:
(J + K)² = (2/3)²
J² + 2JK + K² = 4/9
And subtract twice the product:
J² + K² = 4/9 − 2JK
J² + K² = 4/9 − 2(-4/3)
J² + K² = 4/9 + 8/3
J² + k² = 28/9
Answer:
50 i think but i'm not 100 % sure i'm sorry
Step-by-step explanation:
Yo yo yo so first u simplify everything as 4^2= 16 and 25 squared is 5 so order of operations make 5*2 and that equals 10 so finally
16-10=6 so the answer is 6
You will need to convert them into improper fractions, subtract them, and convert them back to mixed numbers.
5 1/8 - 2 4/8
41/8 - 20/8
21/8
2 5/8
Your answer is 2 5/8.
<u><em>Answer:</em></u>
A. $4397.9
<u><em>Explanation:</em></u>
We are given that Kendra sold 200 shares and that the price per share was $22.1
<u>This means that:</u>
Total value = 200 * 22.1 = $4420
Now, we know that the broker charged 0.5% commission on the total value
<u>This means that:</u>
Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1
<u>Therefore,</u>
Kendra's return = Total value - broker's charge
Kendra's return = 4420 - 22.1 = $4397.9
Hope this helps :)
