The reasonable domain for this function is [tex](x > 0)[/tex] .

The collection of all feasible values for the independent variable is referred to as a function's domain.

When we substitute different values for the independent variable from the domain, the dependent variable's range refers to the set of all conceivable values for that variable.

Let the width of the rectangle be x units.

Thus as per given information length becomes x+4 units.

It is given, the area of rectangle can be expressed by the equation

[tex]y=x^{2} +4x[/tex]

Now let's find domain of this function.

clearly x cannot be zero and x cannot be negative because x represents the width of the rectangle and the width of a rectangle cannot be zero or negative.

Therefore the domain of the function is

[tex](0,\infty)[/tex] or x>0 .

Answer: $1.18 per item

Step-by-step explanation:

9.44/8=$1.18 per item

the correct option is the first one (counting from the top).

The true statement is:

"The leading coefficients of f(x) and g(x) are opposites"

We know that f(x) and g(x) are quadratic functions, and the sum of these two functions is shown in the graph.

We can see that the sum gives a linear graph, so the terms with the exponents of 2 are cancelled by the sum.

This only can happen if f(x) and g(x) have opposite (same absolute value but different sign) leading coefficients, so the quadratic terms are cancelled when we add the functions.

For example in f(x) = 2*x^2 + 3x + 4

                         g(x) = -2x + x + 13

If we add these two functions, we would end with a line.

With that in mind we can conclude that the correct option is the first one (counting from the top).

(in Math)

Interval Notation:

Set Builder Notation:

{x | x < -3 or x > -3}

Step-by-step explanation:

Since this function is a rational function (like a fraction) we have to watch out for what is going on in the denominator. The denominator cannot be zero.

So, 2x + 6 cannot be zero. Let's figure out what makes 2x+6 actually equal to 0.

2x + 6 = 0

Subtract 6.

2x = -6

Divide by 2.

x = -3

Answer:

Step-by-step explanation:

You want to use differences to find the pattern and the next term in the sequence 3, 8, 15, 28, 51, 88, 143.

Subtracting each term from the next, we find the sequence of first differences to be ...

  5, 7, 13, 23, 37, 55

The first differences are not constant, so we know the sequence is not linear. They are not in an arithmetic progression, so we know the sequence is not quadratic. They do not have a common ratio, so we know the sequence is not exponential.

The second differences are the differences of the sequence of first differences. They are ...

  2, 6, 10, 14, 18

The differences of the terms of the 2nd-difference sequence are constant: 4.

  4, 4, 4, 4, 4

Constant 3rd differences mean the original sequence can be described by a 3rd degree polynomial. The coefficients found by a calculator are shown in the attachment.

Since we know the third differences are constant, we can work our way back up the chain of differences to find the next term of the original sequence.

  next 2nd difference = 18 +4 = 22

  next 1st difference = 55 +22 = 77

  next sequence term = 143 +77 = 220

The eighth term should be 220.

a. The value of r = 3, -1/2.

b. The 4th term of each progression;

As, per the given question;

Let the first three terms of GP be a, ar, and ar².

The 1st, 2nd and 3rd terms of a GP equals 1st, 9th and 21st terms of an AP respectively.

where, 'r' is the common ratio in GP and 'd' is the common difference in AP.

Part 1: Multiply equation 1 by 5 and 2 by 2 and subtract 1 from 2.

2ar² - 5ar - 3a = 0

Put a = 8 and solving.

16r² - 40r - 24 = 0.

Factorising the above equation;

(r - 3)(2r + 1) = 0

Thus, r  = 3 and r = -1/2

Part 2:

Case 1: For r = 3; a =8;

ar = a + 8d

d = 2.

Thus, 4th term = a + 3d

                        = 8 + 3×2

4th term = 14.

For GP;

4th term = ar³

              = 8(3)³

4th term = 216.

Case 2: For r = -1/2; a =8;

ar = a + 8d

d = -3/2

Thus, 4th term = a + 3d

                        = 8 + 3×(-3/2)

4th term = 7/2

For GP;

4th term = ar³

              = 8(-1/2)³

4th term = -1.

Therefore, the values for the r and 4th term is estimated.

A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points. The rules that maps the other vertices of the figure to their images is T<-2, -7> (x,y).

What are coordinates?

A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Given that Sanjay determined that one vertex of a figure was mapped to its image by translating the point 2 units left and 7 units down.

In order to translate coordinates, 2 units left we need to subtract 2 units from the x-coordinate of the point, while to translate the point 7 units down we need to subtract 7 from the y-coordinate of the point.

Therefore, the rule that maps the other vertices of the figure to their images is, (x¹,y¹)=(x-2,y-7), or it can bse written as T<-2,-7> (x, y),

where x¹ and y¹ are the coordinates of the points after transliteration.

Hence, the rule that maps the other vertices of the figure to their images is T<-2,-7> (x, y,).

The equation of the given situation for total cost C is C = 3m + 40 where m is the number of miles.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

Given the graph,

Let's say the equation which is representing the situation is

C = (Slope)m + d

Where d is y-intercept = 40

Slope = difference in y's coordinate / difference in x's coordinate

Slope = (70 - 55)/(10 - 5)

Slope = 15/5 = 3

So the equation would be ;

C = 3m + 40

Hence "The equation of the given situation for total cost C is C = 3m + 40 where m is the number of miles".
