The range of possible values of X are X>12.5

In mathematics, the range of a function can refer to one of two closely related concepts:

1. The function's codomain

2. The function's image

In mathematics, a function is an expression, rule, or law that explains a relationship between one variable (the independent variable) and another variable (the dependent variable).

A function is a sort of rule that generates a single output for a single input. In mathematics, a function is an expression, rule, or law that explains a relationship between one variable and another variable.  A good example is Y=X². You will only get one output for y if you enter anything for x. We can say that y is a function of X because X represents the input value.

By using Hin-ges theorem,

(4X-10) > 40

4X > 50

X > 12.5

The equation of the line passes through (-2, -1) and parallel to y = -1/3x - 5 is y = - 1 / 3 x - 5 / 3

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

The equation of the line passes through (-2, -1) and parallel to y = -1/3x - 5

Therefore, the slope of the line is - 1 / 3.

Parallel lines have the same slopes.

Therefore, let's find the y-intercept using (-2, -1)

y = - 1 / 3 x + b

-1  = - 1 / 3 (-2) + b

b = -1 - 2 / 3

b =  -3 - 2/ 3

b = - 5 / 3

The vertex of y=|2x+4|+5 is (-2, 5) and Range of the y=|2x+4|+5 is 5≤y<∞

A relation is a function if it has only one y-value for each x-value.

We need to find the vertex and range of y=|2x+4|+5

f(x)=2x+4

f of x is equal to zero

2x+4=0

Subtract 4 from both sides

2x=-4

Divide both sides by 2

x=-2

y=|2x+4|+5

=|2(-2)+4|+5=|-4+4|+5=5

Hence vertex is (-2, 5)

The range of the y=|2x+4|+5 is 5≤y<∞

Hence vertex is (-2, 5) and Range of the y=|2x+4|+5 is 5≤y<∞

The cubic polynomial for the given function in question can be written as:  x³ -2x² - 16x+ 32 = 0.

What is polynomial?

All the exponents of an algebraic expression called a polynomial must be whole numbers. Any polynomial must have non-negative integer variable exponents. We cannot divide a polynomial by a variable even though it contains variables and constants.

From the table given, we can see the function f(x) = 0 when, x = -4, 2, 4

It means, x+4 = 0, x-4 = 0, x-2 = 0

Multiplying these equations,

(x+4)(x-4)(x-2) = 0

(x²-4x+4x-16)(x-2) = 0

x³- 16x -2x² + 32 = 0

Therefore the cubic polynomial for the given function is:

x³ -2x² - 16x+ 32 = 0

Answer:

38

Step-by-step explanation:

the sum of the interior angles of a triangle is 180

2c + 3c -48 +2c -38 = 180  Combine like terms

7c + -86 = 180  Add 86 to both sides

7x = 266  Divide both sides by 7

x = 38

Answer: c = 38

Step-by-step explanation:

      We know that a triangle's angles add up to 180 degrees. We will write an equation and solve it by combining like terms and then using inverse operations.

   Given:

(2c)° + (2c - 38)° + (3c - 48)° = 180°

   Distribute it out:

2c° + 2c° - 38° + 3c° - 48° = 180°

   Combine like terms:

7c° - 86° = 180°

   Add 86 to both sides:

7c° = 266°

   Divide both sides by 7:

c = 38

Answer:   m∡Ɪ  = 41.8 °

___

Step-by-step explanation:

Use the following mnemonic for right triangles:
 SOH  CAH  TOA ;

in which:
sin   =  opposite/ hypotenuse ;

cos  =  adjacent/ hypotenuse ;

tan =  opposite/adjacent ;

___
We shall solve for the unknown " m∡Ɪ " ;
 that is:  "the measure of Angle Ɪ ".

From looking at the image attached:
 Let's take at  ∡Ɪ .

  We see that the opposite side = 6 ; and that the hypotenuse = 9 ;
So, from the mnemonic mentioned ^above.

We use the SOH component:
    sin Ɪ = opposite /adjacent ;

             = 6/9 ;

      which can be reduced:
             " 6/9 =  (6÷3)/(9÷3) = (2/3) ."

So:  sin Ɪ = (2/3) ;

To solve for  Ɪ ;  

  We use a calculator; to take the (arcsin) of Each Side of the equation:

     [(arcsin) sin Ɪ ]  = (arcsin) ( [tex]\frac{2}{3}[/tex] ) ;

 to get:  Ɪ = 41.810314895779 ;
      [Source used:  Web2.0 Online Scientific Calculator].

Now, we shall round this calculated decimal number to the nearest tenth;  that is;  to the nearest single decimal point that appears after the non-decimal value.
    We have: 41.81... ;

So:  41.8 ? Or: 41.9 ?  If the digit in the hundredth place [that is, the next occurring decimal] is "4 or lesser" [i.e. "0, 1, 2, 3, or 4"] ; then we round down.  

  If the digit in the hundredth place [that is, the next occurring decimal] is "5 or greater" [i.e. "5, 6, 7, 8, or 9"] ; then we round down.

   In our case, we have:  "41.81..." ;
 →  As such, we round down to "41.8" .

  The correct answer is  " m∡Ɪ  = 41.8 °

The value of x = 6 cm

The hypotenuse of a right triangle is its longest side. In other words, the hypotenuse is the side opposite the right angle.

Given that

Adjacent side = 12cm

Angle = 26

We must determine the value of x.

Here we have to use the tan ratio to find the value of x.

tan θ = opposite side/adjacent side

tan 26 = x / 12

Now Multiplying both sides by 12, we get

x = 12 tan 26               [tan 35 = 0.7]

x = 12 x 0.5

x = 6

Therefore, the value of x = 6 cm

Here, d-1 is the largest possible value of N.

Given info,

For an arbitrary Markov chain on a state space consisting of exactly d states, find (with proof) the largest possible positive integer n such that for some states i,j, we have p(n) ij > 0 but p(n) ij.

We will prove that N ≤ d - 1

In light of this, there are states I and j such that the path from I to j has at least N edges, which implies that the path from I to j has at least d edges.

However, since there are only d states, the distance between any two states can be no greater than d-1. N can't thus be bigger than d-1.

Now, d-1 is the largest possible N because if we take a look at a Markov chain, if I is between 1 and d, we can only move to state 2 and if I is already at state d, we can only move to state d-1. However, if I am already at state 1, we can only move to state 1 and if I am already at state 2, we can only move to state i+1.

This sample contains d-1 edges on the way from state 1 to d. N = d-1 hence holds in this situation.

Therefore, N can have a value as large as d-1.

Persons                             Cost

    2                                     148

    4                                     296

    5                                     370

So, the rate of change is,

rate of change = change in cost / change in persons

Rate of change = (222 - 148)/(3 - 2)

= 74/1
