The commutative property apply to compositions of f(x) and g(x) when f(g(x)) and g(f(x)) are equal for all values of x.

The commutative property says that  [tex]a*b=b*a[/tex] , for any binary operation [tex]'*'[/tex]. These binary operations can be addition, multiplication, function composition, etc. But subtraction and division does not follow commutative property.

Here the operation is composition of two functions defined as,

               [tex](fog) (x)= f(g(x))[/tex]  ,where f and g are two functions.

Then the function composition has commutative property when

                      [tex]fog = gof[/tex].

That is, when f(g(x)) = g(f(x))

This means that the commutative property apply to the composition of functions, f(x) and g(x) when f(g(x)) and g(f(x) are equal for all values of x.

The measure of the angle x is 22.5 degrees

Circle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs.

A circle is the locus of all points in a plane which are equidistant from a fixed point

From the given diagram

arc AC = 180 - 135

arcAC = 45 degrees

Since the angle at the vertex is half the intercepted arc, hence;

x = 1/2(arc AC)

x = 1/2(45)

x = 22.5 degrees

Hence the measure of the angle x is 22.5 degrees

gradient = slope. or similar names.

it expresses the "steepness" of the line. how strongly is it going up or down or ... at all ?

it is represented by the ratio

(y coordinate difference / x coordinate difference)

when going from one point on the line to another.

for these 2 points we see (when going from the first to the second)

x changes by +1 (from -1 to 0).

y changes by -6 (from 2 to -4).

so the slope or gradient is

-6/+1 = -6

Coordinate plane is the answer of this problem.

A Coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis

We have been given real numbers A number is real that has no imaginary part the set of all real numbers comprises the rational and the irrationals.

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

So therefore an ordered pair of real numbers can be represented in a plane called the rectangular coordinate system or the Coordinate plane.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The value of the given numbers in the decimal form can be written as,

-√15 = -3.873

√15 = 3.873

15/2 = 7.5

-15/2 = -7.5

-2 3/8 = -2.375

Now, let's check in which options are the numbers arranged correctly.

A.) -√15 < -2 3/8 < -2.75 < 15/2

Since -2 3/8 > -2.75. Therefore, this is wrong.

Angle A = 120°

Since ABCD is a parallelogram, therefore, the angle that is opposite to angle A would also be 120°. Therefore:

Angle C = 120°

Angle D = 180 - 120 = 60°.

Angle DCO = 1/2(angle C) = 1/2(120) = 60°

Angle CDO = 1/2(angle D) = 1/2(60) = 30°

Answer:

-21x-13

Step-by-step explanation:

That is all you need

This density in kilograms per pint is 0.946.

Important conversions:

1 gram = 0.001 kilogram

1 ml = 0.001 litres

1 pint = 0.473 litres

1 litre = 2.113 pints

Step 1 : Convert 2 grams per millilitre of volume (2 g/ml) into kilograms per litre (kg/l)

=> (2  x 1000)/ (0.001) = 2 kg / l

Therefore, we get the density in kilograms per litre (kg/l) as 2 kg/l.

Step 2 : Convert the density in kilogram per litre (kg/l) into kilograms per pint (kg/pint)

=> 2 x 0.473 = 0.946 kg/l

Therefore, by converting 2 grams per millilitre of volume into kilograms per pint, we get the density as 0.946 kg/pint.
