The value of x from the figure shown is 2.19

According to the Pythagoras theorem, the square of the hypotenuse is equivalent to the sum of the square of other two sides.

From the given diagram, the expression below is true;

6^2 = 3^2 + (3+x)^2

Determine the value of x

36 = 9 + (9+6x + x^2)

36 = 18 +6x+x^2

x^2 + 6x - 18 = 0

On factorizing, the value of x is expressed as;

x = -3 + 3√3
x = -3 + 3(1.732)

x = 2.19

Hence the value of x from the figure shown is 2.19

The inequality to represent the temperatures at which the propane is safe to use is -40 < x < 120.

It is said that it is safe to use Propane between the temperatures of -40°C and 120°C.

We already know the use of an equality. It makes the values on both sides of it equivalent.

An inequality compares the values on both sides of it. It informs us which one is greater than or less than the other or if they are equal. That is, inequality has a possibility for equality too.

Here the minimum temperature at which propane is safe to use = -40°C

The maximum temperature at which Propane is safe to use = 120°C

We take a variable 'x' to denote the safe temperature of Propane.

Then according to the information, the inequality to represent the temperatures at which the propane is safe to use is,

            -40 < x < 120

The coordinate of the midpoint of line JK is; (3, 1)

We want to find the midpoint of the line stack JK with bar on top.

The coordinates of the line are;

J(-1,3), K(7,-1)

Now, the formula to find the midpoint is; (x, y) = (x1 + x2)/2, (y1 + y2)/2

Thus, the coordinates of the midpoint of the line are;

(x, y) = (-1 + 7)/2, (3 - 1)/2

(x, y) = 6/2, 2/2

(x, y) = (3, 1)

To find

So, according to the question

We have,

Now, for finding the six times of the cube of x, first we have to find the cube of x

     ∵ The powers will be added when

                 [tex]a^{m}\times a^{n} = a^{m+n}[/tex]

     ∴                        = x⁽¹⁺¹⁺¹⁾

∴ 4th option is correct.

the points ( 0,0) satisfies x = my

the point ( 0, 0 ) is on the graph of y in terms of x .

Tthe difference of depths between them is 1 foot, and the trench which is deeper is the Japan Trench

The depths of the trenches are given as

Japan Trench = 9 km below sea level

Peru-Chile Trench = 8 km below sea level

Both trenches are below the sea level

This means that the deeper trench will have the higher absolute value

The trench with the higher absolute value is the Japan Trench

This is so because 9 is greater than 8

The difference of depths between the trenches is

Difference = 9 - 8

Answer:

Step-by-step explanation:

The value of x is 8.366, y is 4.582 and z is 5.477.

Using Pythagoras theorem in both Triangle as

Triangle 1:

H² = P² + B²

z²= y² + 3²

z² = y² + 9

Triangle 2:

x² = y² + 7²

x² = y² + 49

and, x² = z² - 9 + 49

x² = z² + 40.............(1)

Now, In big Triangle

x² + z² = 10²

x² + z² = 100

Now, from equation (1) we get

z² + 40 + z² = 100

2z² = 60

z² = 30

z = 5.477

and, x²= 30+40 = 70

x= 8.366

and, y²= z² - 9

y² = 21

y= 4.582

The true statements are: (A), (D), (E) and (F).

Statement A is true. A triangle is said to be isosceles if its two sides are of equal length. Considering the triangle STU, the sides ST and TU are the radius of the same circle centered at T and hence of same length. So triangle STU is isosceles.

Statement B is false. In triangle STU, ST and TU being radii of circle T, are equal. But the third side SU is not a radius of any circle in the diagram and so not equal to ST and TU. Since three sides are not of same length, triangle STU is not an equilateral triangle.

Statement C is false. In Triangle STU two sides are composed of a single radii and not of two radii. The third side is not composed of radii.

Statement D is true. In triangle STU, two sides are radii of circle T but the third side, segment SU, is not a radius of any circle shown in the diagram.

Statement E is true. In triangle VWZ, each side is composed of 2 radii which are of same length. Hence three sides are equal and so it is an equilateral triangle.

Statement F is true. Each side of triangle VWZ is composed of two radii that have the same length.
