13/4 is the value of x in function .

What exactly are function and example?

A function is a type of rule that produces one output from one input.   This is illustrated by the equation y=x2. You only get one output for y if you enter anything for x.

                        Considering that x is the input value, we would state that y is a function of x.

f(x) = {  5;  x< 1 }

        { -1/2x + 4 ; x≥ 1 }

 f(4) =  { -1/2  * 4 + 4 }

         =  { -2 + 4 }

         = { 2 }

f( -10) =  { -1/2 * -10 + 4 }

         =  { 5 + 4 }

          = 9

f(0) = { -1/2 * 0 + 4 }

       = { 0 + 4}

The arc length of the arc is (11/5)π inches, or approximately 6.926 inches (rounded to three decimal places).

We may use the following formula to determine the arc length of an arc having a radius of 18 inches and a centre angle of 22°:

(Central angle / 360°) x (2r) Equals arc length

where r denotes the arc's radius.

Inputting the values provided yields:

arc length is equal to (22°/360°) x (2x18 inches).

arc length is equal to 11/180 times 36 inches.

11.5 inches is the length of an arc.

Step-by-step explanation:

No such step-by-step explanation, but we can reason with theorems.

The Vertical Angle theorem states: the opposing angles of two intersecting lines must be congruent, or identical in value.

The Linear Pair theorem states: If two angles form a linear pair, then the measures of the angles add up to 180°.

<1 and <2

Therefore , the solution of the given problem of equation comes out to be  y = 6x + 11.

Mathematical formulas frequently use the same letter to try to impose uniformity between two claims. Many variable academic numbers are shown to be equal using mathematical equations, also known as assertions. The normalise divides 12 and b + 6 into two parts using the result y + 6 = 12 as an illustration. It is possible to determine the connection between each sign component and the number of lines. The significance of a symbol usually contradicts itself.

Here,

In slope-intercept form, the provided equation y = -1/6x - 2 has a slope of -1/6. Consequently, this line's perpendicular inclination is as follows:

=> m2 = -(1/-1/6) = 6

Now that we know the desired line's slope and the spot through which it passes (-2, -1). To determine the solution of a linear equation, we can use its point-slope form:

=> y - y1 = m(x - x1) (x - x1)

where m is the slope 6 and (x1, y1) is the position (-2, -1). By replacing these numbers, we obtain:

=> y + 1 = 6(x + 2) y + 1

=> 6x + 12 y + 1

=> 6x + 11 y - (-1)

=> 6(x - (-2))

As a result, the equation for the line passing through the position (-2, -1) and perpendicular to y = -1/6x - 2 is y = 6x + 11.

Slope is a mathematical term that describes how steep a path is. The ratio of the vertical shift (rise) to the horizontal transition (run) between any two points on a line is more precisely known as the slope of a line. A line's inclination can be zero, positive, negative, or undefinable. A line that has a positive slope is rising as it travels from left to right, whereas a line that has a negative slope is falling as it moves in the opposite direction. A line has a slope of zero if it is straight, and a slope of infinity if it is vertical.

given

The linear equation's point-slope form is:

y - y1 = m(x - x1) (x - x1)

where (x1, y1) is a spot on the line and m denotes the angle of the line's slope. The equation of the line can be expressed as follows using the provided point (-3, -1) and slope of -1/3:

y - (-1) = (-1/3)(x - (-3))

Streamlining the right side:

y + 1 = (-1/3)(x + 3)

What is Function?

Function is the relationship between inputs where each input is related to exactly one output. It is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output, and the output can be traced back to its input.

"y is a function of x" (denoted y = f(x)) means that y varies according to whatever value x takes on.

How to determine

Where F(x) = 2x^4 + x^2 - 10x + 1

So, to calculate f(-10)

f(x) = y

Where x = -10

f(-10) = 2(-10)^4 + (-10)^2 -10(-10) + 1

f(-10) = 2(10000) + 100 + 100 + 1

f(-10) = 20000 + 100 + 100 + 1

f(-10) = 20201

For f(2),

f(x) = y

Where x = 2

f(2) = 2(2)^4 +2^2 -10(2) + 1

f(2) = 2(16) + 4 -20 + 1

f(2) = 32 + 4 -20 + 1

f(2) = 17

For f(3)

f(x) = y

Where x = 3

f(3) = 2(3)^4 + 3^2 -10(3) + 1

The coordinates of the receiver are (x, y) = (10, 5), and the standard form of the hyperbola is x² - 20x + 212.5 = 0.

A hyperbola is the location of all the points on a plane whose distances from two fixed points in the plane differ by an amount that is always constant. The centre, represented by O in the above diagram as the centre of an ellipse, is where two foci are connected by a line segment when they are united by a line segment. The transverse axis of the hyperbola is the line segment that passes across both foci.

From the given situation we have,

The length of the transverse axis is 180/2 = 90 miles.

Using the distance formula between the two transmitters we have:

d1 = √((x - 5)² + y²)

d2 = √((x + 5)² + y²)

Now, the equation of d is:

|d1 - d2| = 90

Simplifying and squaring both sides, we get:

(d1 - d2)² = 8100

Substituting the expressions for d1 and d2 and expanding, we get:

[(x - 5)² + y² - (x + 5)² - y²]² = 8100

-40x² + 800x - 400 = 8100

-40x² + 800x - 8500 = 0

Dividing by -40, we get:

x² - 20x + 212.5 = 0

d1 = √((x - 5)² + y²) = √((7.5)² + y²)

d2 = √((x + 5)² + y²) = √((2.5)² + y²)

Substituting d1 - d2 = 90/2 = 45 and simplifying, we get:

y² - 50y + 450 = 0

Solving for y:

We get y = 5 or y = 45.

Since the receiver is in the first quadrant, we take y = 5.

Therefore, the coordinates of the receiver are (x, y) = (10, 5), and the standard form of the hyperbola is x² - 20x + 212.5 = 0.

If a is the length of one of the legs then the hypotenuse, h,  which is the longest side is given by the equation

The simplified form of the given expression is 1. Using the trigonometric functions sin b = 7/25.

The Pythagorean identity is a trigonometric identity that relates the values of sine and cosine of an angle in a right triangle.

a)Given cos(b) = 24/25, we can use the Pythagorean identity to find sin(b):

sin(b) = √(1 - cos²(b))

         = √(1 - (24/25)²)

         = √(1 - 576/625)

         = √(49/625)

         = 7/25

Now we can use the definitions of the trigonometric functions to find the remaining values:

cos(b) = 24/25

sin(b) = 7/25

tan(b) = sin(b)/cos(b) = (7/25)/(24/25) = 7/24

csc(b) = 1/sin(b) = 25/7

sec(b) = 1/cos(b) = 25/24

cot(b) = 1/tan(b) = (24/7)

b) By simplifying the given expression using the identity:

[tex]tan x = sin x / cos x[/tex]

[tex]cos x+sinxtanx=cosx+sinx(sinx/cosx)[/tex]

By multiplying through by cos x,

cos² x + sin x sin x = cos² x + sin²x

Using the identity sin² x + cos² x = 1,

cos² x + sin² x = 1

cos x + sin x tan x = 1

Combine like terms.

136 + 4x = 180
