9.

Formula for alpha four plus beta four

Answer»

Answer:

1) α^4 + β^4

=> (α²)² + (β²)²

=> (α² + β²)² - 2α²β² by USING a² + b² = (a + B)² - 2ab

=> ((α + β)² - 2αβ)² - 2(αβ)² using the same identity again

We will now substitute the values of α + β and αβ we found in the beginning of the SOLUTION

=> ((-b/a)² - 2c/a)² - 2(c/a)²

=> (b²/a² - 2c/a)² - 2c²/a²

=> ((b² - 2ac)/a²)² - 2c²/a²

=> (b² - 2ac)²/a⁴ - 2c²/a²

=> ((b² - 2ac)² - 2a²c²) / a⁴

=> (b⁴ - 4ab²c + 4a²c² - 2a²c²) / a⁴

13.	Please refer to attachment below — having a hard time answering this one.
Answer» Answer:- Given: a + b + c = 5 -- equation (1) ab + bc + CA = 10 -- equation (2) We KNOW that, a³ + b³ + c³ - 3ABC = (a² + b² + c² - ab - bc - ca)(a + b + c) => (5)[a² + b² + c² -(ab + bc + ca)] Again , a² + b² + c² = (a + b + c)² - 2(ab + bc + ca) Substitute the values, => a² + b² + c² = (5)² - 2(10) = 25 - 10 => a² + b² + c² = 5 => a³ + b³ + c³ - 3abc = 5(5 - 10) => a³ + b³ + c³ - 3abc = - 25 Hence, proved.

13.

Please refer to attachment below — having a hard time answering this one.

Answer»

Answer:-

Given:

a + b + c = 5 -- equation (1)

ab + bc + CA = 10 -- equation (2)

We KNOW that,

a³ + b³ + c³ - 3ABC = (a² + b² + c² - ab - bc - ca)(a + b + c)

=> (5)[a² + b² + c² -(ab + bc + ca)]

Again , a² + b² + c² = (a + b + c)² - 2(ab +

bc + ca)

Substitute the values,

=> a² + b² + c² = (5)² - 2(10) = 25 - 10

=> a² + b² + c² = 5

=> a³ + b³ + c³ - 3abc = 5(5 - 10)

=> a³ + b³ + c³ - 3abc = - 25

Hence, proved.

17.	If zeros of the puadratic polynomial x2+(a+1)x+b are 2 and -3 find the value of a and b
Answer» Answer: $\large\boxed{\sf{a=0,\;\;b=-6}}$ Step-by-step explanation: Given a quadratic POLYNOMIAL such that, ${x}^{2}+(a+1)x+b$ Also, the roots of the polynomial are 2 and -3. Now, we know that, General form of a quadratic polynomial is , $A{x}^{2}+Bx+C$ On Comparing the coefficients, we have, A = 1 B = a + 1 C = b Now, we know that, SUM of roots = -B/A => -(a+1)/1 = 2 +(-3) => -(a+1) = 2 -3 => a + 1 = -(-1) => a = 1-1 => a = 0 And, also, we know that, Product of roots = C/A => b/1 = 2(-3) => b = -6 Hence, the VALUES of a = 0 and b = -6.

17.

If zeros of the puadratic polynomial x2+(a+1)x+b are 2 and -3 find the value of a and b

Answer»

Answer:

$\large\boxed{\sf{a=0,\;\;b=-6}}$

Step-by-step explanation:

Given a quadratic POLYNOMIAL such that,

${x}^{2}+(a+1)x+b$

Also, the roots of the polynomial are 2 and -3.

Now, we know that, General form of a quadratic polynomial is ,

$A{x}^{2}+Bx+C$

On Comparing the coefficients, we have,

A = 1
B = a + 1
C = b

Now, we know that,

SUM of roots = -B/A

=> -(a+1)/1 = 2 +(-3)

=> -(a+1) = 2 -3

=> a + 1 = -(-1)

=> a = 1-1

=> a = 0

And, also, we know that,

Product of roots = C/A

=> b/1 = 2(-3)

=> b = -6

Hence, the VALUES of a = 0 and b = -6.

Amit owns 1500, rs 25 shares of a company which declares a dividend of 14% . He sells the shares at rs 40 each and invests the proceeds in 8%, rs 100 shares at rs 80. What is the change in his annual dividend income ?

Answer»

Given : Amit owns 1500, rs 25 shares of a COMPANY which declares a dividend of 14% . He sells the shares at rs 40 each and invests the proceeds in 8%, rs 100 shares at rs 80

To FIND : change in his annual dividend income

Solution:

Shares 1500

Share FV = Rs 25

Dividend = 14%

annual Dividend = number of shares * ( dividend % /100) * FV

= 1500 * (14/100) * 25

= Rs 5250

Shares SOLD for = 1500 * 40 = Rs 60000

Shares Bought = 60000/80 = 750

Dividend per share = (8/100) 100 = Rs 8

Annual Dividend = 750 * 8 = Rs 6000

Change in his annual Dividend income = 6000 - 5250 = Rs 750

Rs 750 increase in annual Dividend income

Answer» Step-by-step explanation: First in the part of the QUADRILATERAL, we can see their are 2 RESISTORS 14 ohm and 6 ohm. Now we can see they are in series, adding them we get the summation as 20 ohm. Now , we can see ANOTHER resistor in the diagonal as 20 ohm. We can see that the resultant and the diagonal are in parallel resistance. So, we apply parallel combination and get it as 1/20+1/20 = 2/20=10 ohm. Now this result is in series of the other 10 ohm. We get our next result as 20 ohm. Now again we have 20 ohm in parallel combination, so our result is 10 ohm and it is the equivalent resistance of the quadrilateral. Next we have 25 ohm in series . So adding it up our total resistance is 25+10=35ohm. Now to find current. We can find by the formula $voltage = current \times resistance$ Now we have voltage as 70 volts. 70= current×35 current= 2 AMPERES is the ANSWER

Plz plz ans it..... I will surely mark as brainliest.

Answer»

Step-by-step explanation:

First in the part of the QUADRILATERAL, we can see their are 2 RESISTORS 14 ohm and 6 ohm.

Now we can see they are in series, adding them we get the summation as 20 ohm.

Now , we can see ANOTHER resistor in the diagonal as 20 ohm.

We can see that the resultant and the diagonal are in parallel resistance.

So, we apply parallel combination and get it as

1/20+1/20 = 2/20=10 ohm.

Now this result is in series of the other 10 ohm. We get our next result as 20 ohm.

Now again we have 20 ohm in parallel combination, so our result is 10 ohm and it is the equivalent resistance of the quadrilateral.

Next we have 25 ohm in series .

So adding it up our total resistance is

25+10=35ohm.

Now to find current.

We can find by the formula

$voltage = current \times resistance$

Now we have voltage as 70 volts.

70= current×35

current= 2 AMPERES is the ANSWER

1. A rectangle has dimensions (3x + 1)cm by (2x+1)cm. Given that the area of the rectangle is 117 cm2, find the value of x, the perimeter of the rectangle.

Answer»

Step-by-step EXPLANATION:

Given:

dimensions of rectangle are (3x+1) CM by (2x+1)cm

area of rectangle = 117cm2

let l=3x+1, b = 2x+1

sol:

area of rectangle =l*b

= (3x+1)(2x+1)

= 6x2+3x+2x+1

=6x2+5x+1

=6x2-3x-2x+1

= -3x(-2x+1) +1(-2x+1)

=(-2x+1)(-3x+1)

= -2x+1 =0 (or) -3x+1 =0

-2x = -1 -3x = -1

x = -1/-2. x = -1/-3

x = 1/2. x = 1/3

২০১১ সংখ্যাটিতে শূন্য এর স্থানীয় মান কত?

Answer»

নির্ণয় করতে হবে:- ২০১১ সংখ্যাটিতে শূন্য এর স্থানীয় মান কত

সমাধান:- প্রশ্ন অনুসারে আমাদের নির্ণয় করতে হবে ২০১১ সংখ্যাটিতে 0 এর মান কত,

আমরা জানি,প্রতিটি সংখ্যার দুটি মান থাকে , প্রকৃত মান এবং স্থানীয় মান, এবং এ ক্ষেত্রে শূন্য এর প্রকৃত মান 0,

দুই বা ততােধিক অঙ্ক পাশাপাশি বসিয়ে একটি সংখ্যা লেখা হলে সংখ্যাটির সবথেকে ডান দিকে অবস্থিত অঙ্কটি তার নিজের স্থানীয় মান প্রকাশ করে । এবং ক্রমান্বয়ে এর বামে অবস্থিত দ্বিতীয় অঙ্কটি এর স্থানীয় মানের দশগুণ এবং তৃতীয় অঙ্কটি স্থানীয় মানের শতগুণ । অর্থাৎ কোনাে অঙ্ক এক এক স্থান করে বামদিকে সরে গেলে তার মান উত্তরােত্তর দশগুণ করে বৃদ্ধি পায় । তাই বলা যায় কোন সমীক্ষা অবস্থিত কোন অঙ্কের স্থানীয় মান তার অবস্থানের উপর নির্ভর করে। অর্থাৎ অনেকগুলো অঙ্ক নিয়ে গঠিত সংখ্যা এবং সংখ্যায় ব্যবহৃত কোনাে অঙ্ক অবস্থানের উপর নির্ভর করে যে মান প্রকাশ করে তাকে ঐ অঙ্কের স্থানীয় মান বলা হয় ।

আমরা জানি কোন সংখ্যার স্থানীয় মান নির্ণয়ের ক্ষেত্রে নির্দিষ্ট নিয়মটি হল

কোন সংখ্যার স্থানীয় মান= সেই সংখ্যা× উক্ত সংখ্যাটির মান

তাই এক্ষেত্রে 2011 সংখ্যাটির 0 এর স্থানীয় মান = 0×100=000=0
