The division of given rational expression 3x²-9 x / x-2 ÷ x² - 9 / 4 x-8 is 12x / x + 3 provided x ≠ -3

In this question,

we have been given a complex rational expression [tex]\frac{3x^{2} -9x}{x-2}\div \frac{x^2-9}{4x-8}[/tex]

We need to find the division of given rational expression.

We rewrite given rational expression as,

3x²-9 x / x-2 ÷ x² - 9 / 4 x-8

= 3x²-9 x / x-2 / x² - 9 / 4 x-8

= (3x²-9 x / x-2) × (4 x-8 / x² - 9 )

= [tex]\frac{3x(x-3)}{x-2}\times \frac{4(x-2)} {(x+3)(x-3)}[/tex]

= 12x / x + 3     .........(provided x ≠ -3)

Therefore, the division of given rational expression 3x²-9 x / x-2 ÷ x² - 9 / 4 x-8 is 12x / x + 3 provided x ≠ -3

Answer:

< 5 gigabytes

Step-by-step explanation:

Let the number of gigabytes be represented as: g

Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.

Under $60 = less than (<) $60

Hence, our inequality equation is given as:

$35 + $5 × g < 60

35 + 5g < 60

Collect like terms

5g < 60 - 35

5g < 25

g < 25/5

g < 5 gigabytes

Therefore, the number of gigabytes she can use while staying within her budget less than 5 gigabytes

The surface area of earth is 514.4million [tex]Km^{2}[/tex] and the volume of the Earth is 1.1 ×[tex]10^{12}[/tex] [tex]Km^{3}[/tex].

Radius of Earth = 6400 (approximately).

Earth is a sphere. So by using the formula of Surface Area of sphere we can calculate the Surface area of earth as follows,

Surface Area of Earth = 4[tex]\pi r^{2}[/tex] = 4 × (3.14) × [tex](6400)^{2}[/tex]

                                    =  4 × 3.14 × 40960000

                                    = 514457600 [tex]Km^{2}[/tex]

                                    = 514.4million [tex]Km^{2}[/tex]

The surface area of earth is 514.4million [tex]Km^{2}[/tex] .

Similarly, by using the formula of volume of sphere we can calculate the volume area of earth as follows,

Volume of Earth = (4/3)[tex]\pi r^{3}[/tex]

                           = (4/3)×(3.14)×[tex](6400)^{3}[/tex]

                           =(1.3333)(3.14)(2.6214 × [tex]10^{11}[/tex])

                           = 1.0975 × [tex]10^{12}[/tex] [tex]Km^{3}[/tex]

                           = 1.1 ×[tex]10^{12}[/tex] [tex]Km^{3}[/tex]

The volume of the Earth is 1.1 ×[tex]10^{12}[/tex] [tex]Km^{3}[/tex].

Given the question, <11 and <14 are supplementary because they sum up to give 180 degrees. Detail below

These are angles that sum up to give 180 degrees. On the other hand, angles on a straight line sum up to give 180 degrees.

Considering the question given above, we can prove that <11 and <14 are supplementary as follow:

<11 + <12 = 180 (angle on straight line)

But

<12 = <14 (corresponding angles)

Thus,

<11 + <14 = 180

Recall

Angle that sum up to give 180 are called supplementary angles

Therefore,

<11 + <14 = 180 => supplementary

From the illustrations given above, we can see clearly that <11 and <14 are supplementary angles

Answer: If you have to fill in the chart I think you just add them together so aluminum would be +3, phosphide -3, iodide -1, and tin 0

Step-by-step explanation:

The missing term is 6.

Here the sequence is -1,__, 11...

An arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

Here the sequence is in an arithmetic sequence, as there is a common difference between the two numbers.

To find the nth term of the sequence we have a formula:

[tex]a_{n}[/tex] = a + (n-1)d

From this we can find a common difference, as we know the 3rd term of the sequence.

[tex]a_{3}[/tex] = -1 + (3-1) d

11 = -1 + 2d

2d = 12

d = 6

Now we have to the 2nd term of the series we have

[tex]a_{2}[/tex] = -1 + (2-1) 6

   = -1 + 6

   = 5

Therefore the 2nd i.e., the missing term of the sequence is 5

Step-by-step explanation:

Volume of a regular cylindrical container = л r ² h

л = 3.1416   (aprox,)

r = radius

h = height = 15cm (half filled) = 15/2 = 7.5cm

then:

Volume = 3.1416 * (4cm)² * 7.5cm

volume = 3.1416 * 16cm² * 7.5cm

volume =  377 cm³      (aproximadly)

1 cm³ = 0.001 liters

377 cm³ = 0.001*377 = 0.377 liters = 377 mililiters

Each function's vertex, axis of symmetry, maximum or lowest value, domain, and range are all described as follows: Vertex: (125,125); range: (125,125); minimum: at y=125;  x=125; maximum: no., axis of symmetry is x=125.

The domain of a function is the set of values that we are allowed to enter into our function.

The set of values that a function can accept as input is known as its range.

            y=(x-125)²-125

we know that;

y=(x-h)²+k

Vertex: In this form, the vertex (or, in other words, the "pointy bit") is given to us in the (h ,k);here we have (125,125).

Axis of symmetry : Two equal segments of the parabola. It moves straight up and down via the vertex.

Thus, we may formulate an equation for the vertical line that passes through the vertex. It is x=125 in this query..

Maximum and lowest values: Here, we're concerned in examining the vertex to determine whether it is at the maximum or lowest of the parabola's range (i.e., when a negative sign is placed in front of the (x-h) = 0 term, respectively).

We need to position the right triangle Δ MNO in the first quadrant with coordinates , M(0,0) , N (0,a) & O (2a,0).

It is given that Δ MNO with right angle at point M has legs of lengths a and 2a .

We have to position the triangle on coordinate plane.

What is a right angled triangle ?

A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees.

As per the question ;

The triangle is a right angle triangle, so it's two sides can be located

on axis.

Place the right angle of the triangle Δ MNO at M.

i.e., M will have coordinates (0,0)

The origin will allow the two legs to be along the x and y-axes , so position the triangle in the first quadrant.

As N is on the y-axis ;

Its x-coordinate will be 0 and the y-coordinate will be a , because the leg is a units long.

i.e., N will have coordinates (0,a)

As O is on the x-axis,

its y-coordinate will be 0 and the x-coordinate will be 2a , because the leg is 2a units long.

i.e.,

O will have coordinate (2a,0)

We can put these coordinates after placing the triangle in the first quadrant i.e., M (0,0) , N (0,a) & O (2a,0).

In this question,

We have been given a rational equation.

x-1 / x+2 = x² + 2 x-3/x+2

We need to find the solution of given rational equation.

Here, the denominator is same on the both sides.

x-1 / x+2 = x² + 2 x-3/x+2

⇒ x - 1 = x² + 2 x-3

⇒ x² + 2x - 3 - x + 1 = 0

⇒ x² + x -2 = 0

We solve above quadratic equation.

⇒ x² + 2x - x - 2 = 0

⇒ x(x + 2) - (x + 2) = 0

⇒ (x + 2)(x - 1) = 0

⇒ x + 2 = 0                or          x - 1 = 0

⇒ x = -2        or         x = 1
