which inequality best represents the graph?

Answer:

C. [tex]9\pi[/tex]

Step-by-step explanation:

We proceed to solve for [tex]x[/tex] by the Pythagorean Theorem:

[tex](x+1)^{2} = (x-1)^{2} + (2\cdot x - 4)^{2}[/tex] (1)

[tex]x^{2} + 2\cdot x + 1 = (x^{2}-2\cdot x + 1) + (4\cdot x^{2}-16\cdot x + 16)[/tex]

[tex]x^{2} + 2\cdot x + 1 = 5\cdot x^{2}-18\cdot x + 17[/tex]

[tex]4\cdot x^{2} -20\cdot x + 16 = 0[/tex]

[tex](2\cdot x)^{2} -10\cdot (2\cdot x) + 16 = 0[/tex]

[tex](2\cdot x -8)\cdot (2\cdot x -2) = 0[/tex]

There are two different solutions:

[tex]x_{1} = 4[/tex], [tex]x_{2} = 1[/tex]

A solution of [tex]x[/tex] is considered realistic when the length of every side of the triangle is a not negative number.

[tex]x_{1} = 4[/tex]

[tex]UV = 2\cdot (4) - 4[/tex]

[tex]UV = 4[/tex]

[tex]WU = 4 - 1[/tex]

[tex]WU = 3[/tex]

[tex]WV = 4 + 1[/tex]

[tex]WV = 5[/tex]

[tex]x_{2} = 1[/tex]

[tex]UV = 2\cdot (1) - 4[/tex]

[tex]UV = -2[/tex]

[tex]WU = 1 - 1[/tex]

[tex]WU = 0[/tex]

[tex]WV = 1 + 1[/tex]

[tex]WV = 2[/tex]

The only realistic set of solutions is for [tex]x = 4[/tex], and the radius of the circle is represented by the line segment [tex]WU[/tex]: [tex]r = 3[/tex]

And the area of the circle ([tex]A[/tex]) is calculated from the following formula:

[tex]A = \pi\cdot r^{2}[/tex]

[tex]A = \pi\cdot (9)[/tex]

[tex]A = 9\pi[/tex]

The correct answer is C.

Answer:

The cost of the car is $ RS 308,000.

Step-by-step explanation:

Given that the value of a car is deprecting at the rate of 12%, to find the correct value of car when cost of car was $ RS350,000 last year, the following mathematical calculation must be performed:

100 - 12 = 88

88/100 = 0.88

350,000 x 0.88 = X

308,000 = X

Therefore, the cost of the car is $ RS 308,000.

Answer:

Distance cover by Jodie = 1 kilometer

Step-by-step explanation:

Given;

Speed of Jodie = 6 kilometer/ hour

Total time Jodie ran = 10 minutes

Find:

Distance cover by Jodie

Computation:

Total time Jodie ran = 10 minutes = 10 / 60 = 0.1667 hour

Distance = Speed x time

Distance cover by Jodie = Speed of Jodie x Total time Jodie ran

Distance cover by Jodie = 6 x 0.1667

Distance cover by Jodie = 1.002

Distance cover by Jodie = 1 kilometer

Answer:

x=13.84

Step-by-step explanation:

3x + 5x + 5x = 180 degree (sum of interior angles of a triangle is always 180 degeree)

13x = 180

x=180/13

x=13.84

therefore value of x is 13.84  degree

Answer:

x²+4² =8²

x²+16 =64

x² =64-16.

x² =48

x. =√48

answer is option D

Answer:

D

Step-by-step explanation:

The segment x is a perpendicular bisector and divides the triangle into 2 right triangles.

Using Pythagoras' identity in either of the 2 right triangles, then

x² + 4² = 8²

x² + 16 = 64 ( subtract 16 from both sides )

x² = 48 ( take the square root of both sides )

x = [tex]\sqrt{48}[/tex] → D

Answer:

A

Step-by-step explanation:

Given that f(x) is 2x-6, and g(x) is 3x+9, all we have to do is subtract in order to find (f(x)-g(x)):

[tex](f(x)-g(x))=\\\2x-6-(3x+9)=\\2x-6-3x-9=\\-x-15[/tex]

Answer:

Step-by-step explanation:

cuando sumamos la medida de un ángulo en el par con el otro ángulo en el par, el total será 180 grados.

No, the student is not correct. Because sum of a pair of adjacent angles not always sum up to 180°.

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

The sum of the measures of a pair of adjacent angles can be any number, including 180 degrees, but it does not have to be 180 degrees.

No, the student is not correct. Because sum of a pair of adjacent angles not always sum up to 180°.

Answer:

8

Step-by-step explanation:

First we need to figure out what g equals

Since 6 x 8 = 48 your answer would be 8

6 x 8 = 48

~ LadyBrain

The value of g that satisfies the equation is 8.

To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:

6g / 6 = 48 / 6

This simplifies to:

g = 8

Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

======================================================

Explanation:

If you have exactly one right angle, then it is possible to have no parallel lines.   See the diagram below. Refer to the upper figure.

If you had exactly 2 right angles, then that would form a trapezoid. A trapezoid has exactly one pair of parallel lines.

If you had 4 right angles, then it would form a rectangle. Any rectangle is a parallelogram, so we have 2 pairs of parallel lines by this point.

It's not possible to have a quadrilateral with exactly 3 right angles (and the fourth angle is some non-right angle). This is because all four angles of any quadrilateral must add to 360 degrees.

The correct answer is (2 x)/(x - 1).

To simplify.

(4 x²+ 4 x)/(2 x²-2) = 4 x(x + 1)/2(x² - 1)

By this formula

(x² - 1²) = (x + 1)(x - 1).

4 x(x + 1)/2(x + 1)(x - 1) = (2 x)/(x - 1).

Therefore, simplification of (4 x²+ 4 x)/(2 x²-2) is  (2 x)/(x - 1).
