The solution of the given equation /x + x/2 = x+ 4/2x for x is i√2.

According to the given question.

We have an equation 1/x + x/2 = x+ 4/2x.

Since, we have to solve th egiven equation 1/x + x/2 = x+ 4/2x, for x.

Therefore, the solution of the given equation 1/x + x/2 = x+ 4/2x for x is given by

1/x + x/2 = x+ 4/2x

⇒ 1/x - 4/2x = x - x/2

⇒ 1/x -2/x  = x - x/2

⇒ (1-2)/x    = (2x -x)/2

⇒ -1/x  = x/2

⇒ -2 = x^2

⇒ x = √(-2)

⇒ x = i√2   (√-1 = i)

Hence, the solution of the given equation /x + x/2 = x+ 4/2x for x is i√2.

By substitution, the solution of the system of equations, y = 2x - 1 and 3x - y = -1, is (-2 , -5).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

y = 2x - 1     (equation 1)

3x - y = -1     (equation 2)

Since the first equation is already expressed in y in terms of x, substitute the value of y to the second equation.

3x - y = -1     (equation 2)

3x - (2x - 1) = -1

3x - 2x + 1 = -1

Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.

3x - 2x + 1 = -1

3x - 2x = -1 - 1

x = -2

Substitute the value of x in the first equation.

y = 2x - 1     (equation 1)

y = 2(-2) - 1

y = -4 - 1

y = -5

Hence, the solution of the given system of equations is (-2 , -5).

The side of the square inscribed in a square be a units then the required ratio is π : 2.

A square is inscribed in a circle or a polygon if its four vertices are on the circle's circumference or the polygon's sides.

Inscribed in the circle is a square that fits snugly inside a circle. The square's corners will touch but not intersect the circle's boundary, and the diagonal of the square will equal the diameter of the circle. Furthermore, as with any square's diagonal, it equals the hypotenuse of a 45°-45°-90° triangle.

Let the side of the square inscribed in a square be a units.

Hence, the required ratio is 2 : 1.

Let ABCD be a square inscribed in a circle of radius 'r'.

Now, the diameter of the circle is the diagonal of the square.

Therefore, BD = 2r.

In △BDC, using Pythagoras theorem

[tex]BC^2+CD^2=BD^2[/tex]

⇒ [tex]a^2+a^2=(2r)^2[/tex]

⇒ [tex]2a^2=4r^2[/tex]

⇒ [tex]a^2=2r^2[/tex]

Area of square=[tex]2r^2[/tex]

Area of circle =[tex]$$\pi r^2[/tex]

The sequence 3/32, 3/16, 3/8, 3/4, 3/2, 3,6, ... is a geometric sequence with common ratio 2.

To determine whether the sequence is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.

If it is an arithmetic sequence, then:

  a(n) = a(n-1) + d

where d is the common difference.

If it is a geometric sequence, then:

  a(n) = a(n-1) . r

where r is the common ratio.

The given sequence is:

     3/32, 3/16, 3/8, 3/4, 3/2, 3,6, . . . .

Notice that

a(2) : a(1) = 3/16 : 3/32 = 2

Given statement 'The sum of two vectors is the resultant.' is True.

We know that in mathematics, a vector is a quantity that has both magnitude and direction but no position.

Examples : velocity, force and acceleration.

Also, the resultant vector is the vector sum of two or more vectors. We find the resultant vectors by  adding two or more vectors together. Any two vectors can be added if and only if they are the same vector quantity.

For vector P = [tex]a\vec i+b\vec j[/tex] and vector Q = [tex]m\vec i+n\vec j[/tex]

Answer:

X = √2 R , where X is the length of the legs as R is the length of the radius .

Step-by-step explanation:

The opposite sides of two same angled triangle is also same . So in this case we can say two legs are in same length as their opposite angles are same (45°)

Now , suppose the given radius is R (look at the diagram) then total diameter  is 2R ( DIAMETER = 2 × RADIUS )

Now , we will consider the length of the legs are X ( as the are same ).

Now, we will apply Pythagoras theorem ( The squares on the legs of a right triangle is equal to the square on the hypotenuse . )

∵  X² + X² = (2R)²

or , 2X² = 4R²

or, X² = 2R²

We will root both side

X = √2R

So , X is the length of the legs as R is the length of the radius .

Answer:

Common difference = x - 2.

Step-by-step explanation:

Differences:

-2x - 9 - (-3x - 7)

= -2x - 9 + 3x + 7

= x - 2

-x - 11 - (-2x - 9)

= - x - 11 +2x + 9

= x - 2

So, it is Arithmetic.

Answer:

Arithmetic sequence.

Common difference = -x - 11

Step-by-step explanation:

This is an arithmetic sequence.

-3x - 7, -2x - 9,  -x - 11, ...

Find the common difference.

Common difference =second term - first term.

                                 = -2x - 9 - (-3x - 7)

                                = -2x -  9 + 3x  +7

                                = -2x + 3x - 9 + 7      {Combine like terms}

                                = x - 2

If we add the common difference to the second term, we will get the third term.

Third term = second term + common difference

                  = -2x - 9 + x - 2

                  = -2x + x - 9 - 2

                  = -x - 11.

Hence this is an arithmetic sequence.

Step-by-step explanation:

Given that

          -8 ≥ -5x + 2 > -38

To find

So, according to the question

we have,

          -8 ≥ -5x + 2 > -38

For finding the solution of this function let's solve it on two part,

First part

          -8 ≥ -5x + 2,    and

Second part

          -5x + 2 > -38

For solution of first part ,

          -8 ≥ -5x + 2,

Add (-2) both side

We will get,

          -8 +(-2)  ≥ -5x + 2 +(-2)

          -8 -2  ≥ -5x + 2 -2

            -10  ≥ -5x

            10  ≥ 5x

Divide 5 both side,

We will get,

            [tex]\frac{5x}{5} \ge \frac{10}{5}[/tex]

             x ≥ 2

Now, for solution of second part,

          -5x + 2 > -38

Add (-2) both side

We will get,

          -5x + 2 +(-2) > -38+(-2)

          -5x + 2 -2 > -38 -2

                   -5x  > -40

                   40  > 5x

Divide 5 both side,

               5x/5  < 40/5

               x  < 8

32(-5) + 0 + 160 = 0 is the line in the general form of the line the passing through (−5,0) with the slope 32.

A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics. There is no obvious reason why the letter m is used to represent slope, although it first appears in English in O'Brien (1844), who wrote the equation for a straight line as "y = mx + b," and it may also be found in Todhunter (1888), who wrote it as "y = mx + c."

Let us write the given data in slope-intercept form that is

y = m(x) + b

where m = slope of the line

b = y-intercept

So substituting the values we get

0 = 32(-5) + b

-b = -160

b = 160

so we have the slope intercept form

0 = 32(-5) + 160

Converting this to General form

ax + by + c = 0

32(-5) + 0 + 160 = 0
