If sum of the zeros of a quadratic polynomial 5 x^2 - (3 k + 2)x + 1 is 4 find k

Answer»

Answer:

6

Step-by-step explanation:

The GIVEN polynomial is 5x²-(3k+2)x+1

SUM of the zeroes=-b/a=(3k+2)/5

But it is given that sum of the zeroes is 4.

So (3k+2)/5=4

=> 3k+2=4×5=20

=> 3k=20-2

=> 3k=18

=> k=18/3

=> k=6.

Thus the value of k is 18.(answer)

Formula of (a+b)^3. can anybody answer please?

Answer»

ANSWER:

a² + b³ + a³b^4

Step-by-step explanation:

(a + B)³

like this : (a + b)(a + b)(a + b)

Then group: : (a + b)(a + b) and split the first two bracket

=a(a+b) +b(a+b) MULTIPLY

= a² +AB + ab + b²-(after that, introduce the third bracket)

=a² +ab + ab + b²(a + b)- open bracket

= a² + ab + ab +ab² + b³

∴ you COLLECT like terms = a² + b³ +ab +ab + ab²

Then, final answer = a² + b³ + a³b^4

24.	Solve this question (fast)
Answer» Answer: We KNOW that (a + b)² = (a - b)² + 4ab Here • a + b = 2 • a - b = 10 By substituting the values ⇒ (2)² = (10)² + 4ab ⇒ 4 = 100 + 4ab ⇒ 4 - 100 = 4ab ⇒ - 96 = 4ab ⇒ - 96/4 = AB ⇒ - 24 = ab ⇒ ab = - 24 We know that (a + b)² = a² + b² + 2ab Here • a + b = 2 • ab = - 24 By substituting the values ⇒ (2)² = a² + b² + 2(-24) ⇒ 4 = a² + b² - 48 ⇒ 4 + 48 = a² + b² ⇒ 52 = a² + b² ⇒ a² + b² = 52 Therefore the VALUE of a² + b² is 52 and the value of ab is - 24

24.

Solve this question (fast)

Answer»

Answer:

We KNOW that

(a + b)² = (a - b)² + 4ab

Here

• a + b = 2

• a - b = 10

By substituting the values

⇒ (2)² = (10)² + 4ab

⇒ 4 = 100 + 4ab

⇒ 4 - 100 = 4ab

⇒ - 96 = 4ab

⇒ - 96/4 = AB

⇒ - 24 = ab

⇒ ab = - 24

We know that

(a + b)² = a² + b² + 2ab

Here

• a + b = 2

• ab = - 24

By substituting the values

⇒ (2)² = a² + b² + 2(-24)

⇒ 4 = a² + b² - 48

⇒ 4 + 48 = a² + b²

⇒ 52 = a² + b²

⇒ a² + b² = 52

Therefore the VALUE of a² + b² is 52 and the value of ab is - 24

Answer» Answer: 54%< CONCENTRATION of milk in other vessel < 88.89% Step-by-step EXPLANATION: Ratio of milk = 4 X : 5x Ratio of water = 8 y : 9 vessel A milk to water ratio = 4x /8y = x/2y vessel B milk to water ratio = 5x /9y vessel A milk concentration in percentage $vessel \: a \: = \frac{x}{2y} \times 100$ vessel B milk concentration in percentage $vessel \: b \: = \frac{5x}{9y} \times 100$ In any of the one vessel milk concentration is between 60 % and 80 % from vessel A to B $60 < \frac{x}{2y} \times 100 < 80$ Multiply by 10/9 {x/2y 10/9 = 5x /9y}* Concentration In Vessel B $66.67 < \frac{5x}{9y} \times 100 < 88.89$ from vessel B to A $60 < \frac{5x}{9y} \times 100 < 80$ Multiply by 9/10 {5x/9y 9/10 = x/2y}* Concentration in vessel A $54 < \frac{x}{2y} \times 100 < 72$ Since we don't know given concentration percentage of milk for whether vessel A or B , we write what could be the possible range satisfying both condition. 54%< concentration of milk in other vessel < 88.89%

Two solution of milk and water are kept in two vessels A and B.the ratio of quantity of milk in vessels A and B is 4:5 while the ratio of quantity of water in vessels A and B is 8:9. it is known that the concentration of milk in one of these vessels between 60%and 80%.what could be the concentration of milk in other vessels.

Answer»

Answer:

54%< CONCENTRATION of milk in other vessel < 88.89%

Step-by-step EXPLANATION:

Ratio of milk = 4 X : 5x

Ratio of water = 8 y : 9

vessel A milk to water ratio = 4x /8y = x/2y

vessel B milk to water ratio = 5x /9y

vessel A milk concentration in percentage

$vessel \: a \: = \frac{x}{2y} \times 100$

vessel B milk concentration in percentage

$vessel \: b \: = \frac{5x}{9y} \times 100$

In any of the one vessel milk concentration is between 60 % and 80 %

from vessel A to B

$60 < \frac{x}{2y} \times 100 < 80$

Multiply by 10/9 {x/2y * 10/9 = 5x /9y}

Concentration In Vessel B

$66.67 < \frac{5x}{9y} \times 100 < 88.89$

from vessel B to A

$60 < \frac{5x}{9y} \times 100 < 80$

Multiply by 9/10 {5x/9y *9/10 = x/2y}

Concentration in vessel A

$54 < \frac{x}{2y} \times 100 < 72$

Since we don't know given concentration percentage of milk for whether vessel A or B , we write what could be the possible range satisfying both condition.

54%< concentration of milk in other vessel < 88.89%

Answer» Step-by-step explanation: Given A BAG contains 25 balls numbered 1 through 25. Suppose an odd number is considered a ‘Success’. Two balls are drawn from the bag with REPLACEMENT. Find the probability of getting a. Two successes b. exactly one success C. at least one success d. no successes We have odd numbers from 1 to 25 will be 1,3,5,7,9,11,13,15,17,19,21,23,25 Now from 1 to 25 there are 13 odd and 12 even numbers. So P (two successes) = 13/25 x 13/25 = 169 / 625 So P(exactly one success) = 13/25 x 12/25 + 12/25 x 13/25 = 156 /625 + 156/625 = 312 / 625 So P (at least one success) = 1 – P (no success) = 1 – 12/25 x 12/25 = 1 - 144/625 = 481 / 625 So P (No success) = 12/25 x 12/25 = 144 / 625 Reference link will be brainly.in/question/21369591

A bag contains 25 balls numbered 1 through 25. Suppose an odd number is considered a ‘Success’. Two balls are drawn from the bag with replacement. Find the probability of getting a. Two successes b. exactly one success c. at least one success d. no successes

Answer»

Step-by-step explanation:

Given A BAG contains 25 balls numbered 1 through 25. Suppose an odd number is considered a ‘Success’. Two balls are drawn from the bag with REPLACEMENT. Find the probability of getting a. Two successes b. exactly one success C. at least one success d. no successes

We have odd numbers from 1 to 25 will be 1,3,5,7,9,11,13,15,17,19,21,23,25
Now from 1 to 25 there are 13 odd and 12 even numbers.
So P (two successes) = 13/25 x 13/25
= 169 / 625
So P(exactly one success) = 13/25 x 12/25 + 12/25 x 13/25
= 156 /625 + 156/625
= 312 / 625
So P (at least one success) = 1 – P (no success)
= 1 – 12/25 x 12/25
= 1 - 144/625
= 481 / 625
So P (No success) = 12/25 x 12/25
= 144 / 625

LET the ONE number be X and the other number be ( x + 2 ) .

Product of these numbers = 168

$\sf\Longrightarrow x(x+2) = 168 \\\\\Longrightarrow x^2+2x = 168 \\\\\Longrightarrow x^2+2x+1^2= 168 + 1^2 \ \ \ \ \ \ ( Square \ completion \ method )\\\\\Longrightarrow (x+1)^2 = 169 \\\\\Longrightarrow x+1 = \pm 13 \\\\If \ x+1 = +13 \ ,\bf { \ x = 12} \\\\\sf If \ x+1 = -13 \ , \bf \ x = -14$

The numbers are 12 and 14 or -12 and -14 .

Expand (3x+5)^3 whats the answer

Answer»

Answer:

27x^3 + 135x^2 + 225x + 125

Step-by-step explanation:

(3x+5)^3 = (3x)^3 + (5)^3 + 3*3x*5(3x+5)

(3x+5)^3 = 27x^3 + 125 + 45X(3x+5)

(3x+5)^3 = 27x^3 + 125 + 135x^2 + 225x

(3x+5)^3 = 27x^3 + 135x^2 + 225x + 125
