Answer» ★ Answer : given : (x - 2) is a factor of x³ + ax² + bx + 6 and leaves 3 as remainder when divided by (x - 3) Solution : if x - 2 is a factor then, F(2) should be 0 f(x) = x³ + ax² + bx + 6 f(2) = (2)³ + a(2)² + 2b + 6 = 8 + 4a + 2b + 6 14 + 4a + 2b = 0 4a + 2b = -14 2(2a + b) = -14 2a + b = -7 ..... (1) given : f(3) = 3 f(3) = (3)³ + a(3)² + 3b + 6 = 27 + 9a + 3b + 6 = 33 + 9a + 3b = 3 9a + 3b = 3-33 9a + 3b = -30 3(3a + b) = -30 3a + b = -10 ..... (2) (1) - (2) (2a + b) - (3a + b) = -7-(-10) 2a + b - 3a -b = -7 +10 - a = 3 → a = -3 by putting VALUE of a in equation 1... 2a + b = -7 2(-3) + b = -7 -6 + b = -7 b = -7+6 → b = -1 therefore, a = -3 and b= -1.. equation = x³ + (-3)x² + (-1)x + 6 = x³ - 3x² - x + 6

14761.

(x-2) is a factor of (x^3+ax^2+bx+6) leaves remainder 3 on divided by (x-3)

Answer»

★ Answer :

given :

(x - 2) is a factor of x³ + ax² + bx + 6 and leaves 3 as remainder when divided by (x - 3)

Solution :

if x - 2 is a factor then, F(2) should be 0

f(x) = x³ + ax² + bx + 6

f(2) = (2)³ + a(2)² + 2b + 6

= 8 + 4a + 2b + 6

14 + 4a + 2b = 0

4a + 2b = -14

2(2a + b) = -14

2a + b = -7 ..... (1)

given : f(3) = 3

f(3) = (3)³ + a(3)² + 3b + 6

= 27 + 9a + 3b + 6

= 33 + 9a + 3b = 3

9a + 3b = 3-33

9a + 3b = -30

3(3a + b) = -30

3a + b = -10 ..... (2)

(1) - (2)

(2a + b) - (3a + b) = -7-(-10)

2a + b - 3a -b = -7 +10

- a = 3

→ a = -3

by putting VALUE of a in equation 1...

2a + b = -7

2(-3) + b = -7

-6 + b = -7

b = -7+6

→ b = -1

therefore,

a = -3 and b= -1..

equation =

x³ + (-3)x² + (-1)x + 6

= x³ - 3x² - x + 6

Answer» ANSWER: Step-by-step EXPLANATION: Given quadratic equation is= (p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0. On comparing with standard form of quadratic equation i.e ax² + bx + C =0, a≠ 0 Here, a = p+1 , b= -6(p+1) , c= 3(p+9) D(discriminant)= b²-4ac =-6 (p+1)² - 4× (p+1)× 3(p+9) = 36(p+1)² - 12(p+1)(p+9) = 36(p² + 1 + 2p) - 12 (p²+9p+p+9) = 36p² + 36 + 72p - 12p²- 108p-12p- 108 = 36p²-12p² +72p - 108p-12p +36- 108 = 24p² - 48p - 72 = 24(p² - 2p - 3) Since, roots of given equation are EQUAL. D= 0 0 = 24(p² - 2p - 3) (p² - 2p - 3)= 0 p² - 3p +p - 3 = 0 p(p -3) +1(p-3)= 0 (p + 1) (p +3)= 0 (p + 1) (p +3)= 0 p ≠ 0 or p = 3 Hence, required value of p is 3 Put the value of p = 3 in given equation (p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0. (3+1)x² -6(3+1)x + 3(3+9)= 0 4x² -24x +36= 0 4(x² -6x +9)=0 x² -6x +9 = 0 x² -3x -3x +9= 0 x(x -3) -3(x -3)= 0 (x-3)(x-3)= 0 (x-3)= 0 or (x-3)= 0 x = 3 or x= 3 Hence , the roots are x =3, 3.

14765.

Find the value of p for which the quadratic equation (p-1)x²-6(p+1)x+3(p+9)=0 has equal roots. Find the roots.

Answer»

ANSWER:

Step-by-step EXPLANATION:

Given quadratic equation is= (p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0.

On comparing with standard form of quadratic equation i.e ax² + bx + C =0, a≠ 0

Here, a = p+1 , b= -6(p+1) , c= 3(p+9)

D(discriminant)= b²-4ac

=-6 (p+1)² - 4× (p+1)× 3(p+9)

= 36(p+1)² - 12(p+1)(p+9)

= 36(p² + 1 + 2p) - 12 (p²+9p+p+9)

= 36p² + 36 + 72p - 12p²- 108p-12p- 108

= 36p²-12p² +72p - 108p-12p +36- 108

= 24p² - 48p - 72

= 24(p² - 2p - 3)

Since, roots of given equation are EQUAL. D= 0

0 = 24(p² - 2p - 3)

(p² - 2p - 3)= 0

p² - 3p +p - 3 = 0

p(p -3) +1(p-3)= 0

(p + 1) (p +3)= 0

p ≠ 0 or p = 3

Hence, required value of p is 3

Put the value of p = 3 in given equation

(p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0.

(3+1)x² -6(3+1)x + 3(3+9)= 0

4x² -24x +36= 0

4(x² -6x +9)=0

x² -6x +9 = 0

x² -3x -3x +9= 0

x(x -3) -3(x -3)= 0

(x-3)(x-3)= 0

(x-3)= 0 or (x-3)= 0

x = 3 or x= 3

Hence , the roots are x =3, 3.

14774.	If a numerator of a fraction is 4 less than its denominator, if the numerator is decreased by 2 and the denominator is increased by 1 the denominator is twice the numerator. Find the fraction?
Answer» Answer: The fraction is 9 / 13 Step-by-step explanation: LET , denominator of fraction = x then, as given that numerator is 4 less than denominator so , numerator = x - 4 Now, numerator on decreasing by 2 will become ( x - 4 ) - 2 = x - 6 Also, denominator on INCREASING by 2 will become ( x ) + 1 = x + 1 so, As given that on decreasing numerator by 2 and increasing denominator by 1 , the denominator will become TWICE the numerator therefore, → x + 1 = 2 ( x - 6 ) → x + 1 = 2 x - 12 → 1 + 12 = 2 x - x → x = 13 so, we get Denominator = x = 13 now, Numerator = x - 4 = 13 - 4 = 9 Therefore, The fraction will be 9 / 13 .

14774.

If a numerator of a fraction is 4 less than its denominator, if the numerator is decreased by 2 and the denominator is increased by 1 the denominator is twice the numerator. Find the fraction?

Answer»

Answer:

The fraction is 9 / 13

Step-by-step explanation:

LET , denominator of fraction = x

then, as given that numerator is 4 less than denominator

so , numerator = x - 4

Now,

numerator on decreasing by 2 will become

( x - 4 ) - 2 = x - 6

Also, denominator on INCREASING by 2 will become

( x ) + 1 = x + 1

so, As given that on decreasing numerator by 2 and increasing denominator by 1 , the denominator will become TWICE the numerator

therefore,

→ x + 1 = 2 ( x - 6 )

→ x + 1 = 2 x - 12

→ 1 + 12 = 2 x - x

→ x = 13

so, we get Denominator = x = 13

now,

Numerator = x - 4 = 13 - 4 = 9

Therefore,

The fraction will be 9 / 13 .

Find the surface area and the volume of a sphere with radius 1.4 cm.

Answer»

TO FIND :

Find the surface area and the VOLUME of a sphere.

SOLUTION :

★ Surface area = 4πr²

➨Surface area = 4 × 22/7 × (1.4)²

➨ Surface area = 24.64 cm²

Hence, the surface area of sphere is 24.64 cm².

★ Volume of the sphere = 4/3 πr³

➨ Volume of the sphere = 4/3 × 22/7 × (1.4)³

➨ Volume of sphere = 11.5 cm³

Hence, the Volume of sphere is 11.5 cm³.

Now, a = 5 × 3 = 15 cm b = 5 × 4 = 20 cm c = 5 × 5 = 25 cm Perimeter = 15 + 20 + 25 = 60 cm. *hope* it *helps* *you* *mate* . *PLEASE* *thank* *and* ♏*ark* my *answer* as *brainliest. @ ANUSHA* ❤✌

14792.

The area of a triangle is 150 cm2 and its sides are in the ratio 3 : 4 : 5. What is its perimeter?

Answer»

Let coefficient of ratios be X

a = 3x

b = 4x

c = 5x

Using Heron's FORMULA,

s = ( 3 + 4 + 5 ) x / 2

= 12X / 2

= 6x .

√ [ s ( s - a ) ( s - b ) ( s - c ) ]

√ 6x ( 6x - 3x ) ( 6x - 4x ) ( 6x - 5x )

√ 6x × 3x × 2x × 1x

√ 36X ^ 4

√ 6x ^ 2

Area = 150 ^ 2

6x ^ 2 = 150

x ^ 2 = 150 / 6

x ^ 2 = 25

x = 5 ^ 2 .

Now,

a = 5 × 3 = 15 cm

b = 5 × 4 = 20 cm

c = 5 × 5 = 25 cm

Perimeter = 15 + 20 + 25 = 60 cm.

hope it helps you mate .

Find the value of p for which the quadratic equation (p-1)x²-6(p+1)x+3(p+9)=0 has equal roots. Find the roots.

Given quadratic equation is= (p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0.

On comparing with standard form of quadratic equation i.e ax² + bx + C =0, a≠ 0

Here, a = p+1 , b= -6(p+1) , c= 3(p+9)

D(discriminant)= b²-4ac

=-6 (p+1)² - 4× (p+1)× 3(p+9)

= 36(p+1)² - 12(p+1)(p+9)

= 36(p² + 1 + 2p) - 12 (p²+9p+p+9)

= 36p² + 36 + 72p - 12p²- 108p-12p- 108

= 36p²-12p² +72p - 108p-12p +36- 108

= 24p² - 48p - 72

= 24(p² - 2p - 3)

Since, roots of given equation are EQUAL. D= 0

0 = 24(p² - 2p - 3)

(p² - 2p - 3)= 0

p² - 3p +p - 3 = 0

p(p -3) +1(p-3)= 0

(p + 1) (p +3)= 0

(p + 1) (p +3)= 0

p ≠ 0 or p = 3

Hence, required value of p is 3

Put the value of p = 3 in given equation

(p + 1)x² - 6(p + 1) x + 3 (p + 9) = 0.

(3+1)x² -6(3+1)x + 3(3+9)= 0

4x² -24x +36= 0

4(x² -6x +9)=0

x² -6x +9 = 0

x² -3x -3x +9= 0

x(x -3) -3(x -3)= 0

(x-3)(x-3)= 0

(x-3)= 0 or (x-3)= 0

x = 3 or x= 3

Hence , the roots are x =3, 3.
