We have been given a Quadratic equation, where we have to find the real values of x ~

So, let's proceed with middle term splitting method :

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} + 5x - 6 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: x {}^{2} + 6x - x - 6 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x(}^{} x + 6) - 1(x + 6) = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: (x + 6)(x - 1) = 0[/tex]

Now, we have two conditions here~

Either (x + 6) = 0

answer:-1

reason :

Once the numbers add up, once they decrease

what does it mean?

it mean that:

The first and second numbers we add are one, they become two

The second and third numbers are one and two. We subtract the second number from the third number, it becomes negative one and ...

1+1=2

1-2=-1

2+(-1)=1

-1-(+1)=-2

1+(-2)=-1

so we should - them

-2-(-1)=-1

The next number in the given sequence will be negative 1.

What is a sequence?

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.

The first and second numbers we add are one, they become two.

The second and third numbers are one and two. We subtract the second number from the third number, it becomes a negative one, and ...

1 + 1 = 2

1 - 2 = - 1

2 + (-1) = 1

-1 - (+1) = -2

1 + (-2) = -1

Then the next number in the sequence will be given as,

-2 - (-1) = -1

The next number in the given sequence will be negative 1.

The circumference of the circle is  [tex]C =\dfrac{20\pi}{4+\pi}[/tex]  when A is a minimum.

The circumference of the circle is the length of the curve traced out from the fixed point which is equidistant from the locus of the curve.

Let the side of the square be s

and the radius of the circle be r

The perimeter of the square is = 4s

The circumference of the circle is =2πr

Given that the length of the wire is 20 cm.

According to the problem,

4s + 2πr =20

⇒2s+πr =10

[tex]s=\dfrac{10-\pi r}{2}[/tex]

The area of the circle is = πr²

The area of the square is = s²

A represents the total area of the square and circle.

A=πr²+s²

Putting the value of s

[tex]A =\pi r^2 +(\dfrac{10-\pi r}{2})^2[/tex]

[tex]A =\pi r^2 +(\dfrac{10}{2})^2-2\times \dfrac{10}{2}\times \dfrac{\pi r}{2}+(\dfrac{\pi r}{2})^2[/tex]

[tex]A = { \pi r^2}(\dfrac{4+\pi}{4})-5\pi r+25[/tex]

For maximum or minimum [tex]\dfrac{dA}{dr}=0[/tex]

Differentiating with respect to r

[tex]\dfrac{dA}{dr}=\dfrac{2\pi r(4+\pi )}{4}-5 \pi[/tex]

Again differentiating with respect to r

[tex]\dfrac{d^2A}{dr^2}=\dfrac{2\pi (4+\pi )}{4}[/tex]    > 0

For maximum or minimum

[tex]\dfrac{dA}{dr}=0[/tex]

[tex]\dfrac{2\pi r(4+\pi )}{4}-5 \pi=0[/tex]

[tex]r = \dfrac{10\pi}{\pi (4+\pi)}[/tex]

[tex]r=\dfrac{10}{4+\pi}[/tex]

Therefore the circumference of the circle is

Step-by-step explanation:

Step-by-step explanation:

you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.

if yes, it was a solution, and if just only one is false, then it was not a solution.

(3, -2) in

y + 4x = 10

5x - y = 13

so,

-2 + 4×3 = 10

-2 + 12 = 10

10 = 10 true

5×3 - (-2) = 13

15 + 2 = 13

17 = 13 false

so, it was NOT a solution.

which question

Step-by-step explanation:

give us clarity please

The required trigonometric identity is 1/2[sin(x + y) - sin(x - y)] = cosxsiny

To answer the question, we need to know what trigonometric identities are

Trigonometric identities are relationships between the trigonometic ratios.

Since we require cosxsiny

Given that

So, subtracting both expressions, we have

sin(x + y) - sin(x - y) = sinxcosy + cosxsiny - (sinxcosy - cosxsiny)

= sinxcosy + cosxsiny - sinxcosy + cosxsiny

= sinxcosy - sinxcosy + cosxsiny  + cosxsiny

= 0 + 2cosxsiny

= 2cosxsiny

sin(x + y) - sin(x - y) = 2cosxsiny

Dividing through by 2, we have

1/2[sin(x + y) - sin(x - y)] = cosxsiny

So, the required trigonometric identity is 1/2[sin(x + y) - sin(x - y)] = cosxsiny

x and 90 are supplementary.

x + 90 = 180

x = 90

Answer:

x=13

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    (2*x+14)-((3*x+1))=0

1.1      Solve  :    -x+13 = 0

Subtract  13  from both sides of the equation :

                     -x = -13

Multiply both sides of the equation by (-1) :  x = 13

radius(R) = 12 units

arc = 134°

Find: area of sector

Plan: if you think about it, a sector area is a fractional part of the full area of the circle. It’s a pie piece.

A(circle) = π R^2

134° is 134°/360° = 67/180 That is 67/180 th of the full circle

area (S) = 67/180 (π R^2)

S = 67/180 (π )(12^2) = 67/180(144 π) = 54 π units^2 or

The arc YOR of the circle is the major arc

In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.

The formula for Area of a sector is given as;

θ/360 * πr²

where;

θ is the central angle of the sector

r is radius

Now, looking at the given options we can say that the only one that represents the area of the sector is;

A = n/360 * πr²

where n is the central angle of the sector

Given data ,

Let the arc of the sector be represented as YOR

Now , the center of the circle is Q

The angle subtended by the minor arc of the circle = 150°

So , the remaining angle = 360° - 150° = 210°

And , the angle subtended by the major arc = 210°

So , the arc YOR is the major arc of the circle

Hence , the major arc is YOR
