What is a fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction consists of a numerator, displayed above a line, and a non-zero denominator, displayed below that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.

The indefinite integral, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]

We have to find the indefinite integral,

    [tex]\int {sin(9x)} \, dx[/tex]

using the substitution 9x = u.

So we need to change the variable of integration from x to u using this substitution.

9x = u ⇒ 9 dx = du

So   [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{1}{9} \int{sin(u) \ du[/tex]

                          = 1/9 (- cos(u)) + C,   [ Since integral of sin(u) = -cos(u) ]

where C is the integration constant which is often put when evaluating indefinite integrals.

Now replacing u with x to get the final answer,

1/9 (- cos(u)) + C = -1/9 cos(9x) + C

Therefore,   [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]

Answer:

I'm pretty sure it's -1 but correct me if I'm wrong

Answer: x=-1

Step-by-step explanation:

x=-1

because

2x - 10

over = 3x

4

we can put everything in parentheses and multiply by 4

2x - 10

4( over )= (3x) 4

4

The 4's on the left side will cancel out around and leave

2x - 10

on the right we multiply 3x x 4 which equals 12x

rewrite the equation

2x - 10 = 12x

subtract 2x on each side with the variable.

2x - 10 = 12x

-2x -2x

the 2x's on the left will cancel out.

on the right 12x - 2x equals 10x

now the equation is

-10=10x

but we are not done

divide 10 on each side

on the left -10/ 10 equals -1 because one number is negative and that does not give a postive result.

on the right 10x/ 10 the 10's cancel out leaving the varible x

we are left with

x=-1

According to the illustration below The figure becomes convex if vertex C is reflected over the BD line.

A reflex angle is any angle larger than 180 degrees but less than 360 degrees. For example, a reflex angle is 270 degrees. There are several sorts of angles in geometry, including acute, obtuse, and right angles that are less than 180 degrees. There is a reflex angle for every acute as well as an obtuse angle.

The reflex angle can be measured in one of two ways: either measure its inner angle and subtract it from 360° (to get the reflex angle) and measure the reflex angle itself.

The sine for the right triangle  A is 3/5.

The ratio between the side opposite the angle and the triangle's hypotenuse is known as the sine (sin) of an acute angle in a right-angled triangle. A right angle in geometry and trigonometry is an angle that is exactly 90 degrees, or 2 radians, which is equivalent to a quarter turn. If a ray is positioned so that its terminal is on a line and they are equal, the neighbouring angles are right angles.

Sin(A) = opposite/hypotenuse

           =BC/AB

           =3/AB

9 + 16 = AB2

25 = AB2

AB = 5

Hence,

The first five terms of a sequence with explicit formula a(n) = 2n - 1 are 1,3,5,7,9  (G)

An arrangement of numbers with particular pattern is called a sequence. In general, there are four types of sequence: arithmetic sequence, geometric sequence, quadratic sequence, and special sequence.  

Suppose we are given an explicit formula for the nth term of a sequence, then its terms can be evaluated by substituting n = 1, 2, ...

The explicit formula of the given sequence:

a(n) = 2n - 1

Take n = 1, then

a(1) = 2.(1) - 1 = 1

Take n = 2, then

a(2) = 2.(2) - 1 = 3

Take n = 3, then

a(3) = 2.(3) - 1 = 5

Take n = 4, then

What is utility function and perfect complements?

A utility function is a standard rule which is assigned to all consumption bundles. And it is represented as two good models which are known as domain and codomain. It is also used to represent the individual items for the goods or services beyond their monetary value. Similarly, when two goods are consumed perfectly then they are called perfect complements.

Answer: (-4,7)

Step-by-step explanation:

Answer: only the first one

Step-by-step explanation:

The given function is f(x) = 2x-4,

We have to find the equation where the reflection of this function is over the x-axis.

There are two types of reflections in general when we talk about functions;

Now we take an example that we are provided with a point with coordinates (x, y). If we want to reflect it over the x-axis, then the coordinates of this point will become (x, -y). This is because the values of y are negative when we move above the x-axis and positive when we move below the x-axis and vice versa.

The equation to show this is: y = -f(x).

We multiply the entire function, f(x), to find it by a negative. Since f(x) = 2x-4, the transformed function is f(x) = -2x+4.

Therefore, the function rule for the function shown is -f(x).

The formulae for finding the new coordinates are given by

x' = x cosθ - y sinθ

y' = x sinθ + y cosθ

Substituting θ = 270

x' = x cos270° - ysin270°  = x(0) - y( -1) = y

y' = x sin270° + y cos270° = x(-1) + y( 0) = x

If two of the three numbers are 24 and 42, then the GCF of these two numbers is 6 and the third number is possibly 48.

Factor is a number which when a number is divided will result to another number(whole). For two or more numbers, the largest common factor that they have is called the Greatest Common Factor (GCF).

To find the GCF of 24 and 42, list all the factors of both numbers.

24 : 1, 2, 3, 4, 6, 8, 12, 24

Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is obtuse.

By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.

4.2 + 6.4 > 7.6

6.4 + 7.6 > 4.2

7.6 + 4.2 > 2.6

Hence, these set of numbers can be the measures of the sides of a triangle.

According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:

acute if [tex]a^{2} + b^{2} < c^{2}[/tex]

obtuse if  [tex]a^{2} + b^{2} > c^{2}[/tex]

right if  [tex]a^{2} + b^{2} = c^{2}[/tex]

∴The longest side is 7.6.

Hence, a = 4.2, b = 6.4 and c = 7.6;

Consider [tex]a^{2} + b^{2}[/tex] :

= [tex]4.2^{2} + 6.4^{2}[/tex]

= 58.6.

Now consider [tex]c^{2}[/tex] :

= [tex]7.6^{2}[/tex]

=57.76.

Thus,  [tex]a^{2} + b^{2} > c^{2}[/tex]

Hence, the triangle is obtuse.
