The solution to the inequality p + 3.6 > −5.8 is p ∈ (-9.4, ∞) the number line (B) represents the solution set to the inequality.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is:

p + 3.6 > −5.8

After simplification:

p > -5.8 - 3.6

p > -9.4

The number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.

After plotting on the number line:

p ∈ (-9.4, ∞)

Thus, the solution to the inequality p + 3.6 > −5.8 is p ∈ (-9.4, ∞) the number line (B) represents the solution set to the inequality.

Answer:

54°

Step-by-step explanation:

Given BD bisects ∠ABC, which means it divided the angle into two equal parts, we can write the following equation to find the value of x, then the measure of ∠ABC:

9x = 8x + 3 subtract 8x from both sides

x = 3

The measure of ∠ABC = ∠ABD + ∠DBC

∠ABC = 9x + 8x + 3 add like terms

∠ABC = 17x + 3 replace x with 3

∠ABC = 17*3 + 3 and

∠ABC = 54°

Answer:

[tex]1+\cos x[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{4cm}\underline{Trigonometric Identities}\\\\$\csc \theta=\dfrac{1}{\sin \theta}\\\\\\\cot \theta=\dfrac{\cos \theta}{\sin\theta}\\\\\\\cos^2 \theta + \sin^2 \theta = 1$\\\end{minipage}}[/tex]

[tex]\begin{aligned}\implies \dfrac{ \sin x}{ \csc x - \cot x} & = \dfrac{ \sin x}{\dfrac{1}{\sin x} - \dfrac{\cos x}{ \sin x}}\\\\& = \dfrac{ \sin x}{\dfrac{1 - \cos x}{\sin x}}\\\\& = \sin x \times \dfrac{\sin x}{1 - \cos x}\\\\& = \dfrac{\sin^2 x}{1-\cos x}\\\\& = \dfrac{1-\cos^2x}{1-\cos x}\\\\& = \dfrac{(1-\cos x)(1+ \cos x)}{1-\cos x}\\\\& = 1 + \cos x\end{aligned}[/tex]

that is the solution and just writing so you can have the answer

What are permutation and combination?

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

The length of pipes are 235 inch and 47 inch.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

length of pipe = 282 inch

as, One piece is five times the length of the other.

then the pipe is in 6 parts

So, length of each = 282/6 = 47 inch

and, then the length of pieces

=47 * 5

= 235 inches

Answer:

620

Step-by-step explanation:

617 rounded to the nearest ten = 620.

The number 617 when rounded to the nearest ten will be 620.

We examine the digit in the position of the one and decide whether it is closer to the previous ten or the next ten to round a number to the closest ten.

The digit in the ones place for the number 617 is 7. We round up to the next ten since 7 is bigger than or equal to 5, so we do.

The tens digit is raised by one and all the digits to its right are set to zero in order to round up to the following ten.

So, when we round 617 to the nearest tenth, we get 620.

Answer: Quadrant I

Step-by-step explanation:

By using the Pythagorean theorem, both the distance from A to M and the distance from B to M are approximately equal to 8.25 units.

Diameters are line segments whose endpoints lie on the same circumference and whose midpoint is the center of the circle associated to that circumference. In this problem we know the locations of the endpoints (points A and B) and a third point (point M) inside the diameter, and based on all this information we must determine the distances between points A and M and points B and M.

Each case can be found by using the Pythagorean theorem in the following form:

Points A and M

AM = √[[- 5 - (- 3)]² + [- 4 - (- 12)]²]

AM = 2√17

AM ≈  8.25

Points B and M

BM = √[[- 7 - (- 5)]² + [4 - (- 4)]²]

BM = 2√17

BM ≈ 8.25
