SOLUTION

GIVEN

In an art & craft class Sameer learnt how to paint walls of a room. He PRACTICED a lot and tried it on small models. Finally, he decided to paint his room at HOME. The room was cuboidal in SHAPE, with length being the longest and height the shortest.

The volume of the room can be written in a polynomial is x³ + 6x² + 3x - 10

TO DETERMINE

i) The length of cuboid in polynomial

ii) If x = 2 then the area of floor

iii) If x = 8, then its height is

IV) What type of polynomial the volume

EVALUATION

Here it is given that the volume of the room can be written in a polynomial is x³ + 6x² + 3x - 10

Now

$\sf{ {x}^{3} + 6 {x}^{2} + 3x - 10 }$

$\sf{ = {x}^{3} - {x}^{2} + 7 {x}^{2} - 7x+ 10x - 10 }$

$\sf{ = {x}^{2}(x - 1) + 7x(x - 1) + 10(x - 1)}$

$\sf{ = (x - 1)({x}^{2} + 7x + 10)}$

$\sf{ = (x - 1)({x}^{2} + 5x + 2x+ 10)}$

$\sf{ = (x - 1)(x + 2)(x + 5)}$

Thus we have

Length = x + 5

Breadth = x + 2

Height = x - 1

(i) Length of the cuboid in polynomial

= ( x + 5 ) unit

(ii) Area of the floor

$\sf{ = (x + 2)(x + 5)}$

$\sf{ = {x}^{2} + 5x + 2x + 10 }$

$\sf{ = {x}^{2} +7x + 10 }$

For x = 2 the area of the floor

$\sf{ = {2}^{2} +(7 \times 2) + 10 }$

$\sf{ = 4 + 14 + 10 }$

$\sf{ =28}$

(iii) If x = 8 we have

Height

= 8 - 1 unit

= 7 unit

(iv) In the polynomial the highest power of its variable that appears with NONZERO coefficient is 3

Hence the polynomial is a cubic polynomial

Answer» Answer: Re(z)=0 Given: Z is a COMPLEX number. And the equation is ,\|z-1\|=\|z+1\| Solution: As we know that, z = x + iyz=x+iy Substitute z in the equation, \|x + iy - 1\| = \|x + iy + 1\|∣x+iy−1∣=∣x+iy+1∣ (x + iy - 1) = ± (x + iy + 1)(x+iy−1)=±(x+iy+1) (Here,'+' doesn't satisfy the equation.) (x + iy - 1) = - (x + iy + 1)(x+iy−1)=−(x+iy+1) x + iy - 1 = - x - iy + 1x+iy−1=−x−iy+1 2x + 2iy = 02x+2iy=0 x + iy = 0x+iy=0 So, Re(z)=0 And ALSO, IMAGINARY PART of z=0.

For any complex number z if |z+1| = |z-1| then show that Re(z) = 0 do it fast please

Answer»

Answer:

Re(z)=0

Given:

Z is a COMPLEX number.

And the equation is ,|z-1|=|z+1|

Solution:

As we know that,

z = x + iyz=x+iy

Substitute z in the equation,

|x + iy - 1| = |x + iy + 1|∣x+iy−1∣=∣x+iy+1∣

(x + iy - 1) = ± (x + iy + 1)(x+iy−1)=±(x+iy+1)

(Here,'+' doesn't satisfy the equation.)

(x + iy - 1) = - (x + iy + 1)(x+iy−1)=−(x+iy+1)

x + iy - 1 = - x - iy + 1x+iy−1=−x−iy+1

2x + 2iy = 02x+2iy=0

x + iy = 0x+iy=0

So,

Re(z)=0

And ALSO, IMAGINARY PART of z=0.

does INDEED lie on the circle. A straight line passing between that point and the centre of the circle

Solve: this question please anyone BUT CORRECT

Answer»

Answer

$\sf \dashrightarrow \dfrac{3}{2x - y} + \dfrac{8}{<klux>X</klux> + 2y} = 3 \: \: --- (i)$

$\sf \dashrightarrow \dfrac{12}{x + 2y} - \dfrac{6}{2x - y} = 1 \: \: --- (ii)$

Let $\sf \dfrac{1}{2x - y}$ be u.

Let $\sf \dfrac{1}{x + 2y}$ be V.

So, the equations become

$\sf \dashrightarrow 3u + 8v = 3$

$\sf \dashrightarrow 12v - 6u = 1$

By FIRST equation,

$\sf \dashrightarrow 3u + 8v = 3$

$\sf \dashrightarrow 3u = 3 - 8v$

$\sf \dashrightarrow u = \dfrac{3 - 8v}{3}$

Now, let's find the value of v by SECOND equation.

$\sf \dashrightarrow 12v - 6u = 1$

$\sf \dashrightarrow 12v - 6 \bigg( \dfrac{3 - 8v}{3} \bigg) = 1$

$\sf \dashrightarrow 12v - \dfrac{18 - 48v}{3} = 1$

$\sf \dashrightarrow \dfrac{36v - 18 - 48v}{3} = 1$

$\sf \dashrightarrow \dfrac{-12v - 18}{3} = 1$

$\sf \dashrightarrow -12v - 18 = 3$

$\sf \dashrightarrow -12v = 3 + 18$

$\sf \dashrightarrow -12v = 21$

$\sf \dashrightarrow v = \dfrac{21}{-12}$

$\sf \dashrightarrow v = \dfrac{-7}{4}$

Now, let's find the value of u by first equation.

$\sf \dashrightarrow 3u + 8v = 3$

$\sf \dashrightarrow 3u + 8 \bigg( \dfrac{-7}{4} \bigg) = 3$

$\sf \dashrightarrow 3u + \dfrac{-56}{4} = 3$

$\sf \dashrightarrow 3u + (-14) = 3$

$\sf \dashrightarrow 3u - 14 = 3$

$\sf \dashrightarrow 3u = 3 + 14$

$\sf \dashrightarrow 3u = 17$

$\sf \dashrightarrow u = \dfrac{17}{3}$

We know that,

$\sf \dashrightarrow \dfrac{1}{2x - y} = u$

$\sf \dashrightarrow \dfrac{1}{2x - y} = \dfrac{17}{3}$

$\sf \dashrightarrow 3 = 17(2x - y)$

$\sf \dashrightarrow 34x - 17y = 3 \: \: --- (iii)$

We also know that,

$\sf \dashrightarrow \dfrac{1}{x + 2y} = v$

$\sf \dashrightarrow \dfrac{1}{x + 2y} = \dfrac{-7}{4}$

$\sf \dashrightarrow 4 = -7(x + 2y)$

$\sf \dashrightarrow -7x -14y = 4 \: \: --- (iv)$

Now, by third equation,

$\sf \dashrightarrow 34x - 17y = 3$

$\sf \dashrightarrow 34x = 3 + 17y$

$\sf \dashrightarrow x = \dfrac{3 + 17y}{34}$

Now, let's find the value of y by fourth equation.

$\sf \dashrightarrow -7x - 14y = 4$

$\sf \dashrightarrow -7 \bigg( \dfrac{3 + 17y}{34} \bigg) - 14y = 4$

$\sf \dashrightarrow \dfrac{-21 - 119y}{34} - 14y = 4$

$\sf \dashrightarrow \dfrac{-21 - 119y - 476y}{34} = 4$

$\sf \dashrightarrow \dfrac{-21 - 595y}{34} = 4$

$\sf \dashrightarrow -21 - 595y = 4 \times 34$

$\sf \dashrightarrow -21 - 595y = 136$

$\sf \dashrightarrow -595y = 136 + 21$

$\sf \dashrightarrow -595y = 157$

$\sf \dashrightarrow y = \dfrac{157}{-595}$

$\sf \dashrightarrow y = \dfrac{-157}{595}$

Now, we can find the value of x by third equation.

$\sf \dashrightarrow 34x - 17y = 3$

$\sf \dashrightarrow 34x - 17 \bigg( \dfrac{-157}{595} \bigg) = 3$

$\sf \dashrightarrow 34x - \dfrac{-2669}{595} = 3$

$\sf \dashrightarrow \dfrac{20230x + 2669}{595} = 3$

$\sf \dashrightarrow 20230x + 2669 = 595 \times 3$

$\sf \dashrightarrow 20230x + 2669 = 1785$

$\sf \dashrightarrow 20230x = 1785 - 2669$

$\sf \dashrightarrow 20230x = -884$

$\sf \dashrightarrow x = \dfrac{-884}{20230}$

$\sf \dashrightarrow x = \dfrac{-442}{10115}$

Hence, the VALUES of x and y are -442/10115 and -157/595 respectively.

Answer»

Given : Shanta WANTS to make a rectangular park for children to PLAY.

The area of the park is increased by 75 square units if its length is decreased by 5 units and breadth is increased by 5 units.

area will be increased by 164 units if its length is increased by 2 units and breadth is increased by 2 units.

To Find : the dimensions of the park.

Solution:

the dimensions of the park.

Length = L and Breadth = B

Area = LB

The area of the park is increased by 75 square units if its length is decreased by 5 units and breadth is increased by 5 units.

=> LB + 75 = (L - 5) (B + 5)

=> LB + 75 = LB + 5L - 5B - 25

=> 5L - 5B = 100

=> L - B = 20

area will be increased by 164 units if its length is increased by 2 units and breadth is increased by 2 unit

=> LB + 164 = ( L + 2)(B + 2)

=> LB + 164 = LB + 2L + 2B + 4

=> L + B = 80

L + B = 80

L - B = 20

=> L = 50

B = 30

Area = 50 * 30 = 1500 sq units

the dimensions of the park. = Length 50 unit and Breadth = 30 units

For any complex number z if |z+1| = |z-1| then show that Re(z) = 0 do it fast please​

Answer:

Re(z)=0

Given:

Z is a COMPLEX number.

And the equation is ,|z-1|=|z+1|

Solution:

As we know that,

z = x + iyz=x+iy

Substitute z in the equation,

|x + iy - 1| = |x + iy + 1|∣x+iy−1∣=∣x+iy+1∣

(x + iy - 1) = ± (x + iy + 1)(x+iy−1)=±(x+iy+1)

(Here,'+' doesn't satisfy the equation.)

(x + iy - 1) = - (x + iy + 1)(x+iy−1)=−(x+iy+1)

x + iy - 1 = - x - iy + 1x+iy−1=−x−iy+1

2x + 2iy = 02x+2iy=0

x + iy = 0x+iy=0

So,

Re(z)=0

And ALSO, IMAGINARY PART of z=0.
