3.	Prove that 6-3√15 is a rational number
Answer» Let us assume that 6-3√15 is rational. THEREFORE, we can write it in the FORM of p/q. Here, p & q are co- prime and q ≠ 0. ⟹ 6 -3√15 = p/q ⟹ -3√15 = p/q - 6 ⟹ √15 = (p-6q)/-3Q ⟹ √15 = (6q-p)/3q As p & q both are INTEGER..... Therefore, (6q-p)/3q is a rational number. But √15 is a irrational number. ✰We KNOW that, a rational number can never be equal to irrational number. ☞ Hence, √15 ≠ (6q-p)/3q ✰So, our contradiction is wrong & 6 -3√15 is not a rational number. $\text{[math]}$ ☞ It’s an irrational number. Hence, ( proved)

Prove that 6-3√15 is a rational number

Answer»

Let us assume that 6-3√15 is rational.

THEREFORE, we can write it in the FORM of p/q.

Here, p & q are co- prime and q ≠ 0.

⟹ 6 -3√15 = p/q

⟹ -3√15 = p/q - 6

⟹ √15 = (p-6q)/-3Q

⟹ √15 = (6q-p)/3q

As p & q both are INTEGER.....

Therefore, (6q-p)/3q is a rational number.

But √15 is a irrational number.

✰We KNOW that, a rational number can never be equal to irrational number.

☞ Hence, √15 ≠ (6q-p)/3q

✰So, our contradiction is wrong &

6 -3√15 is not a rational number.

$\text{[math]}$

☞ It’s an irrational number.

Hence, ( proved)

Here, f(x)=x⁴+1 Divisor=x+1 Comparing with x- $\alpha$ we will get, $\alpha=-1$ $\sf{\therefore{Remainder=f(\alpha)=f(-1)}}$ $\sf{\therefore{Remainder=(-1)^{4}+1}}$ $\sf{\therefore{Remainder=1+1=2}}$ The remainder is 2. _______________________________ Verification: ⠀⠀⠀⠀⠀x-1 ) x⁴+0x³+0x²+1 ) x³+x²+1 ⠀⠀⠀⠀⠀ x⁴- x³ ⠀⠀⠀⠀-⠀⠀+ ⠀⠀⠀__________ ⠀⠀⠀⠀⠀x³+0x² ⠀⠀⠀⠀⠀x³- x² ⠀⠀⠀⠀-⠀⠀+ ⠀⠀⠀__________ ⠀⠀⠀⠀⠀x²+1 ⠀⠀⠀⠀⠀x²-1 ⠀⠀⠀⠀-⠀⠀+ ⠀⠀⠀__________ ⠀⠀⠀⠀⠀⠀⠀2 Hence verified, since remainder is 2.

how to use remainder theorem for x^4 +1 divided by x+1 with division steps please... really urgent ...

Answer»

Remainder theorem

When a polynomial F(x) is DIVIDED by x- $\alpha$ and the DIVISION is continued until the remainder is not SMALLER than divisor, then the remainder is f( $\alpha$ ).

Here,

f(x)=x⁴+1

Divisor=x+1

Comparing with x- $\alpha$

we will get, $\alpha=-1$

$\sf{\therefore{Remainder=f(\alpha)=f(-1)}}$

$\sf{\therefore{Remainder=(-1)^{4}+1}}$

$\sf{\therefore{Remainder=1+1=2}}$

The remainder is 2.

Answer» Step-by-step explanation: DRAW the x and y axes. Mark the units along the x and y axes with a suitable scale. (i) To plot the point A (3 , 5) Here, the x-coordinate of A is 3 and the y-coordinate of A is 5. Both are positive. HENCE the point A (3 , 5) lies in the QUADRANT I. Start at the Origin. Move three units to the right along the x-axis. Then TURN and move 5 units up parallel to Y-axis and mark the point A (3 , 5). (ii) To plot the point B (2 , 7) Here, the x-coordinate of B is -2 which is negative and the y-coordinate of B is 7 which is positive. Hence the point B (-2 , 7) lies in the quadrant II. Start at the Origin. Move 2 units to the left along the x-axis. Then turn and move 7 units up parallel to y-axis and mark the point B (-2 , 7). (iii) To plot the point C (-3 , -5) Here, the x-coordinate of C is -3 and the y-coordinate of C is -5. Both are negative. Hence the point C (-3 , -5) lies in the quadrant III. Start at the Origin. Move 3 units to the left along the x-axis. Then turn and move 5 units down parallel to y-axis. and mark the point C (-3, -5). (iv) To plot the point D (2 , 7) Here, the x-coordinate of the point D is 2 which is positive and the y-coordinate of D is -7 which is negative. Hence the point D (2 , -7) lies in the quadrant IV. Start at the Origin. Move 2 units to the right along the x-axis. Then turn and move 7 units down parallel to y-axis and mark the point D (2 , -7). (v) To plot the point O (0, 0) This is the origin. Both the x and y coordinates are zeros. It is the point of intersection of the axes x and y. Mark the point O (0,0). solution

Answer»

Step-by-step explanation:

distance between sun and venus=1.08*10^11 m

distance between venus and earth=

(distance b/w sun and earth) - (distance

b/w sun and venus)

=1.49*10^11 m - 1.08*10^11 m

The another side of the triangle

Perimeter of triangle = sum of all AIDES

30 = 12 + 12 + another side

30 = 24 + another side

30-24 = another side

6 = another side

Area of triangle = 1/2 * 12 *8

Answer» AREA of CIRCLE = πr^2 1386 = πr^2 r^2 = 1386/π r = √1386/π so CIRCUMFERENCE is 2πr = 2 * π √1386/π = 23.14√1386/3.14 = 6.28. 21 = 131.9

44.

The area of circle is 1386msq find circumference

Answer»

AREA of CIRCLE = πr^2

1386 = πr^2

r^2 = 1386/π

r = √1386/π

so CIRCUMFERENCE is

2πr = 2 * π *√1386/π

= 2*3.14*√1386/3.14

= 6.28. * 21

= 131.9
