4.	When p(x) x^4+2x^3-3x+2-1 is divided by (x-2) what will the remainder???
Answer» Answer: Remainder = 21 Step-by-step explanation: I guess you have some mistake in the question. Here is the corrected statement We have been given the the EXPRESSION:- $x^{4} + 2x^{3} - 3x^{2} + x - 1$ We are REQUIRED to FIND the remainder when it is DIVIDED by:- $x - 2$ Let $x - 2 = 0$ $x = 2$ Substitute the value of 'x' in the expression:- $p(2) = (2)^{4} + 2(2)^{3} - 3(2)^{2} + (2) - 1$ $p(2) = 16 + 2(8) - 3(4) + (2) - 1$ $p(2) = 16 + 16 - 12 + 2 - 1$ $p(2) = 21$ $x^{4} + 2x^{3} - 3x^{2} + x - 1$ $x - 2$ Therefore, when is divided by then the remainder is 21 !

4.

When p(x) x^4+2x^3-3x+2-1 is divided by (x-2) what will the remainder???

Answer»

Answer:

Remainder = 21

Step-by-step explanation:

I guess you have some mistake in the question. Here is the corrected statement

We have been given the the EXPRESSION:-

$x^{4} + 2x^{3} - 3x^{2} + x - 1$

We are REQUIRED to FIND the remainder when it is DIVIDED by:-

$x - 2$

Let $x - 2 = 0$

$x = 2$

Substitute the value of 'x' in the expression:-

$p(2) = (2)^{4} + 2(2)^{3} - 3(2)^{2} + (2) - 1$

$p(2) = 16 + 2(8) - 3(4) + (2) - 1$

$p(2) = 16 + 16 - 12 + 2 - 1$

$p(2) = 21$

$x^{4} + 2x^{3} - 3x^{2} + x - 1$ $x - 2$ Therefore, when is divided by then the remainder is 21 !

Need help fr Dis ques.

Answer»

Answer:

ANS: 0

Step-by-step explanation:

Let x/b+c-a=y/c+a-b=Z/a+b-c=k

then

x=(b+c-a)k

y=(c+a-b)k

z=(a+b-c)k

Then

(b-c)x+(c-a)y+(a-b)z

=(b-c)(b+c-a)k +(c-a) (c+a-b)k + (a-b)(a+b-c)k

=k[ b²-c²-a(b-c) +c²-a²-b(c-a)+a²-b²-c(a-b) ]

=k( b²-c²+c²-a²+a²-b²-ab+ca-bc+ab-ca+bc)

7.	Prove that ✓2 is irrational
Answer» Step-by-step explanation: Given √2 is irrational number. Let √2 = a / b where a,b are integers and b ≠ 0 Now √2 = a / b ⇒ 2 = a2 / b2 ⇒ 2B2 = a2 ∴ 2b2 is divisible by 2 ⇒ a2 is divisible by 2 ⇒ a is divisible by 2 ∴ let a = 2C a2 = 4c2 ⇒ 2b2 = 4c2 ⇒ b2 = 2c2 ∴ 2c2 is divisible by 2 ∴ b2 is divisible by 2 so b is divisible by 2 As a are b are divisible by 2 . this CONTRADICTS our supposition that a/b is written in the simplest FORM Hence our supposition is wrong ∴ √2 is irrational number. Hope it helps.. Please mark it BRAINLIEST.. Follow me!

7.

Prove that ✓2 is irrational

Answer»

Step-by-step explanation:

Given √2 is irrational number.

Let √2 = a / b where a,b are integers and b ≠ 0

Now √2 = a / b

⇒ 2 = a2 / b2

⇒ 2B2 = a2 ∴ 2b2 is divisible by 2

⇒ a2 is divisible by 2

⇒ a is divisible by 2 ∴ let a = 2C a2 = 4c2

⇒ 2b2 = 4c2

⇒ b2 = 2c2 ∴ 2c2 is divisible by 2 ∴ b2 is divisible by 2 so b is divisible by 2

As a are b are divisible by 2 . this CONTRADICTS our supposition that a/b is written in the simplest FORM

Hence our supposition is wrong ∴ √2 is irrational number.

A bus moves from station a to station B with a speed of 40 km per hour travelling a distance of 100 KM it then travels from station a to station C covering a distance of 200 km with a speed of 60 km per hour find the average speed of the bus for the entire journey

Answer»

Answer:

51.42 Km/hr

Step-by-step explanation:

time TAKEN from A to B = 100/40 = 5/2 hr

from B to C = 200/60 = 10/3 hr

average SPEED = total distance / total time taken

= 300 /( ( 5/2) + ( 10/3 ) )

= ( 300 x 6 ) / 35

Answer:

14

Step-by-step EXPLANATION:

if x/y = 5/3 ,

let's assume x = 5a , y = 3a

since x + y = 56

5a + 3a = 56

8A = 56

a = 7

implies,

x = 5(7 ) = 35

y = 3(7) = 21

Answer» When the area is 120 CM And the formula for area is 1/2 X BASE x height. So when we do half of 120 we get 60. The only numbers where the differences is 14 of the sides in the triangle are 5 and 12. Even their difference is seven and their product is 60. So we have sides 5 and 12. Now we need the length of the other side (the REMAINING one). To find that length we have to find the hypotenuse whose formula is Square of a side + Square of b side = Square of c side = Square of 5+ square of 12 =the remaining side = 25+144=169( Square of 13) The length of the remaining side is 13.

Product of two number is 15338148. If one number is 483, what is the other number

Answer»

<P>Answer:

31756

Step-by-step explanation:

Product of TWO numbers = 15338148

Hence, we can GIVE it as a variable

v X y = 15338148(p)

v = 483

p/v =y

15338148/483 = 31756

43.

Find the value of:(1+cot^2) (1+cos) (1-cos)

Answer»

Answer:(1 + cot2∅)(1 - cos∅)(1 + cos∅) = 1

{USE , (a + B)(a - b) = a² - b² }

(1 + cot2∅)( 1 - cos²∅) = 1

[ use, 1 - cos²x = sin²x]

(1 + cot2∅)(sin²∅) = 1

( 1 + tan2∅)(sin²∅) = tan2∅

use, FORMULA,

tan2∅ = 2tan∅/(1 - tan²∅)

( 1 - tan²∅ +2tan∅)sin²∅/(1 - tan²∅) = 2tan∅/( 1 - tan²∅)

(1 -tan²∅+ 2tan∅)sin²∅ = 2tan∅

( 1 - tan²∅+2tan∅)/cosec²∅ = 2tan∅

( 1 - tan²∅ + 2tan∅)/(1 + cot²∅) = 2tan∅

( 1 - tan²∅ + 2tan∅)tan∅/(1 +tan²∅) = 2

tan∅ - tan³∅ +2tan²∅ = 2 + 2 tan²∅

tan³∅ - tan∅ +2 = 0
