Answer» Answer: Step-by-step EXPLANATION: When x+1 is a factor, p(-1) = 0 p(x) = x⁴ + 2x³ + 2x² +x +1 p(-1) = (-1)⁴ + 2(-1)³ + 2(-1)² +(-1) + 1 = 1 + 2(-1) + 2(1) + (-1) + 1 = 1 -2 +2 -1 +1 =1 ∵ (x+1) is not a factor of p(x) as p(x) ≠0

4.

Determine which of the following polynomial has (X+1) factor x^4+2x^3+2x^2+X+1

Answer»

Answer:

Step-by-step EXPLANATION:

When x+1 is a factor, p(-1) = 0

p(x) = x⁴ + 2x³ + 2x² +x +1

p(-1) = (-1)⁴ + 2(-1)³ + 2(-1)² +(-1) + 1

= 1 + 2(-1) + 2(1) + (-1) + 1

= 1 -2 +2 -1 +1

=1

∵ (x+1) is not a factor of p(x) as p(x) ≠0

Answer»

Step-by-step explanation:

ANSWER

2log3+3log5+5log2

We know that, logxy=ylogx,

Using the above PROPERTY we can reduce the GIVEN equation as,

=log32+log53+log25

=log9+log125+log32

also, logx+logy+logz=logxyz, HENCE we can write the above as,

=log(9×125×32)

=log(36000)

∴ 2log3+3log5+5log2 can be WRITTEN as a single logarithm as log36000.

Answer» Let 2 digit NUMBER be X and y According to the Question, The sum of 2 digit number is 12 ⇒ x + y = 12 ⟶ ⟶ ⟶ [Equation 1] Original Number: 10x + y On interchanging the digits; 10y + x Now, (10y + x) = 18 + (10x + y) ⇒ 10y + x = 18 + 10x + y ⇒ 10y - y = 18 + 10x - x ⇒ 9y = 18 + 9x ⇒ 9y - 9x = 18 ⇒ 9(y - x) = 18 ⇒ (y - x) = 18 ÷ 9 ⇒ (y - x) = 2 ⟶ ⟶ ⟶ [Equation 2] Adding Equation 1 and 2, x + y = 12 {+} -x + y = 2 2y = 14 → 2y = 14 → y = 14 ÷ 2 ∴ y = 7 Substitute value of y in Equation 1 to find the value of x x + y = 12 ⇒ x + 7 = 12 ⇒ x = 12 - 7 ∴ x = 5 Now, let's find the number. Original Number = 10x + y → Original Number = 10(5) + 7 → Original Number = 50 + 7 ∴ Original Number = 57

11. The sum of the digits of a two-digit number is 12. The number obtainedby interchanging its digits exceeds the given number by 18. Find thenumber.[CBSE 2006)

Answer»

Let 2 digit NUMBER be X and y

According to the Question,

The sum of 2 digit number is 12

⇒ x + y = 12 ⟶ ⟶ ⟶ [Equation 1]

Original Number: 10x + y

On interchanging the digits; 10y + x

Now,

(10y + x) = 18 + (10x + y)

⇒ 10y + x = 18 + 10x + y

⇒ 10y - y = 18 + 10x - x

⇒ 9y = 18 + 9x

⇒ 9y - 9x = 18

⇒ 9(y - x) = 18

⇒ (y - x) = 18 ÷ 9

⇒ (y - x) = 2 ⟶ ⟶ ⟶ [Equation 2]

Adding Equation 1 and 2,

x + y = 12

{+} -x + y = 2

2y = 14

→ 2y = 14

→ y = 14 ÷ 2

∴ y = 7

Substitute value of y in Equation 1 to find the value of x

x + y = 12

⇒ x + 7 = 12

⇒ x = 12 - 7

∴ x = 5

Now, let's find the number.

Original Number = 10x + y

→ Original Number = 10(5) + 7

→ Original Number = 50 + 7

∴ Original Number = 57
