hello could someone explain the law of sines to me?

Answer:

x < 5

Step-by-step explanation:

the dot is empty so we don’t consider 5

The coloured arrow continues to the left so we use this symbol : < (minor)

x<5

The inequality for the number line show is x<5.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We can see that the inequality starts from 5 moves towards 2.

As, the starting of number line have open dot which shows we cannot include 5.

So, the inequality will have sign '<'.

Now, the inequality of the number line is

x < 5.

The equation that the speed of an object is speed = distance/time

From the question, we have the following parameters that can be used in our computation:

Parameter = Object

Argument = Speed

By definition, the speed of an object is the ratio of the distance moved by the object and the time travelled by the object

Mathematically, this can be represented as

Speed = Distance : Time

Express as fraction

Speed = Distance/Time

Answer: 180cm^2

Step-by-step explanation:

The equation is  a^2 + b^2 = c^2

a^2 = area of square 3 = 80cm^2

b^2 = area of square 2 = 100cm^2

c^2 = a^2 + b^2 = 80 + 100 = 180cm^2

What in mathematics is a quadratic equation?

x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Given that:

A = x^(2) - 3x - 18

By solving this equation we can get the values of length and breath of rectangle

A = x^(2) - 6x + 3x - 18

A = x(x-6)+3(x-6)

A = (x-6)(x+3)

Hence the area of rectangle is equal to L * W

Step-by-step explanation:

Multiply 42 by 1/3 which is 14.

Then subtract 42-14 because your subtracting the discount from the original price which gives you 28.

The function operation h(8) - f(-7) of the functions f(x) = -4x+1, and h(x) = 19-3x is -34.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, solve for the output value of h(8) by replacing x with 8 and simplify.

h(x) = 19 - 3x

h(8) = 19 - 3(8)

h(8) = 19 - 24

h(8) = -5

Next, solve for the output value of f(-7) by replacing x with -7 and simplify.

f(x) = -4x + 1

f( -7 ) = -4( -7 ) + 1

f( -7 ) = 28 + 1

f( -7 ) = 29

Now, replace the function designators with the actual output values.

h(8) - f(-7) =  -5 - ( 29 )

h(8) - f(-7) =  -5 - 29

h(8) - f(-7) =  -34

Therefore, the output of the function operation h(8) - f(-7) is -34.

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circular functions) that make up trigonometry.

A branch of mathematics called trigonometry examines connections between triangles' sides and angles. Due to the fact that every straight-sided shape can be decomposed into a group of triangles, trigonometry can be found throughout all of geometry.

The equation of the line passing through the given points and having slope -2/7 is obtained as y = -2/7m - 2.

A straight line can be written in the slope-intercept form as, y = mx + c.

In order to obtain the slope, the ratio of the difference of the coordinates are taken and c is the y-intercept which can be found by substituting x = 0 in the equation.

The given point and the slope for line are as (14,-6) and -2/7 respectively.

The general form of slope-intercept equation is as below,

y = mx + c

Substitute the value of x = 14, y = -6 and m = -2/7 to get,

-6 = -2/7 × 14 + c

⇒ c = -6 + 4 = -2

Thus, the equation can be written as follows,

y = mx + c

Substitute m = -2/7 and c = -2 to obtain,

y = -2/7x + (-2)

⇒ y = -2/7m - 2

Hence, the equation of the line is given as y = -2/7m - 2.

A set comprises of a collection of members or elements which are objects in the set that together are taken as one object by itself.

The specified sets are;

D = {2, 5, 7}

E = {2, 4, 5, 6}

For the provided points (-7,-8) and (-5,-6) on the line, the slope is 1.

The slope of a line is a measure of its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). Determine the coordinates of two points along the line that you choose. Find the difference between these two points' y-coordinates (rise). Find the difference between these two points' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.

Here,

Slope=(y2-y1)/(x2-x1)

=(-6-(-8))/(-5-(-7))

From this definition, we can get the h-intercept giving the starting point of the firework, as follows:

h(0) = -4(0)² + 16(0) + 20 = 20 feet.

The height after 3 seconds is calculated with the numeric value as follows:

h(3) = -4(3)² + 16(3) + 20 = 32 feet.

The coefficients of the quadratic function are given as follows:

a = -4, b = 16, c = 20.

Due to the negative coefficient a, this is a concave down function, meaning that the vertex is a maximum point.

The t-coordinate of the vertex is given as follows:

We can infer from the data set provided that more women than men are interested in basketball.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

From table given in question

Number of males that like basketball = 21

Number of females that like basketball = 29

Percentage of males that like basketball =  (21/50)*100 = 42%

Percentage of females that like basketball =  (29/50)*100 = 58%

Measure of angle I greater than angle K and J. Therefore, option D is the correct answer.

Given that, in triangle IJK, JK=18, KI=11, and IJ=14.

If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side.

Here, JK is the longest side and KI is the shortest side

So, opposite to side JK, angle I is the biggest and opposite to the side KI angle J is the smallest

Here, the measure of IJ is greater than the side KI, then the angle K opposite to side IJ is greater than the angle J

Thus, m∠I>m∠K>m∠J

Measure of angle I greater than angle K and J. Therefore, option D is the correct answer.
