I need the x|x domain and the asymptotic
The domain of the function R(x) is (-∞, -4) U (-4, 3) U (3, ∞).
The vertical asymptote is x = -4 and x = 3
The horizontal asymptote is y = 1.
What is a domain?In Mathematics, a domain refers to the set of all real numbers (x-values) for which a particular function is defined.
In Mathematics, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.
By critically observing the graph shown in the image attached below, we can logically deduce the following domain:
Domain = {0, ∞}.
In conclusion, an asymptote is a line which the graph of any given function approaches but would never cross or touch;
Vertical asymptote is x = -4 and x = 3
Horizontal asymptote is y = 1.

If you were to buy a $1,000 computer in tennessee, how much would it cost in williamson county?.
A $1,000 computer in Williamson County, Tennessee would cost $1,092.50 after including the sales tax.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
The sales tax rate in Tennessee is 7%, but the rate in Williamson County is 2.25% higher, making it 9.25%.
To calculate the cost of a $1,000 computer in Williamson County, you would need to add the sales tax to the base price:
Sales Tax = Base Price x Sales Tax Rate
Sales Tax = $1,000 x 0.0925
Sales Tax = $92.50
Therefore, the total cost of the computer in Williamson County would be:
Total Cost = Base Price + Sales Tax
Total Cost = $1,000 + $92.50
Total Cost = $1,092.50
Therefore, a $1,000 computer in Williamson County, Tennessee would cost $1,092.50 after including the sales tax.

total loan = $28 million + $23 million
= $51 million.
2. Liabilities:
a. Checkable Deposits:
The bank received $92 million in checkable deposits.
b. Required Reserves:
As mentioned above, the required reserves amount to $4.968 million.

Answer: 18% of youth used the internet elsewhere.
Step-by-step explanation:
At first, this problem might seem confusing since there could be places other than home with different percentages, and it feels as if you don't know enough to solve the problem.
But in reality, it breaks down to home or any other place in the world! If you're not at home, you need to exist somewhere.
So, it's actually as simple as 100% (you cannot have a total greater than 100% in the real world) - 82% = 18%
So, 18% of youth used internet in a place other than home.

Which is the graph of the function f/x )= x 2 2x 3?; Which graph represents the function f/x )= 4 x?; How do you find a function on a graph?; Which is one of the transformations applied to the graph of f/x )= x2 to change it into the graph?
The graph of the function f(x) = x² + 2x + 3 is a parabola with vertex (-1, 2).
You can use the vertical line test on a graph to determine whether a relation is a function. If it is impossible to draw a vertical line that intersects the graph more than once, then each x-value is paired with exactly one y-value. So, the relation is a function.
Given, the function is f(x) = x² + 2x + 3
We have to find the graph of the function.
Let y = x² + 2x + 3
Put x = -3
y = (-3)² + 2(-3) + 3
= 9 - 6 + 3
= 9 - 3
y = 6
Put x = -2
y = (-2)² + 2(-2) + 3
= 4 - 4 + 3
y = 3
Put x = -1
y = (-1)² + 2(-1) + 3
= 1 - 2 + 3
= 4 - 2
y = 2
Put x = 0
y = (0)² + 2(0) + 3
= 0 + 0 + 3
y = 3
Put x = 1
y = (1)² + 2(1) + 3
= 1 + 2 + 3
= 3 + 3
y = 6
We can plot the graph using the points.
The graph of the function f(x) = x² + 2x + 3 is a parabola with vertex (-1, 2).

A triangle has a base of 16 inches and a height of 1/8 inches. What is its area?
Answer:
1 in²
Step-by-step explanation:
The area of the triangle calculated using the area formula is 1 in²
Given the Parameters :
Base of triangle = 16 inches
Height of triangle = 1/8 inches
Area of a triangle can be obtained using the relation :
Area = 1/2 × base × height
Substituting the Parameters into the equation :
Area of triangle = 1/2 × 16 × 1/8 = 1 in²
Therefore, the area of the triangle is 1 in²
write a question in y=a x b^x whose graph passes through the Coordinate points (2,12) and (3,24)
The graph of y = 3 x 2^x passes through the coordinate points (2,12) and (3,24).
To write a question in the form of y=a x b^x that passes through the coordinate points (2,12) and (3,24), we need to solve for the values of a and b.
First, let's substitute the coordinates (2,12) into the equation:
12 = a x b^2
Next, let's substitute the coordinates (3,24) into the equation:
24 = a x b^3
We now have two equations with two unknowns (a and b), which we can solve using algebra.
From the first equation, we can solve for a:
a = 12 / b^2
We can then substitute this value of a into the second equation:
24 = (12 / b^2) x b^3
Simplifying this equation, we get:
2 = b
We can then substitute this value of b back into the equation for a:
a = 12 / 2^2
a = 3
Therefore, the equation of the graph that passes through the coordinate points (2,12) and (3,24) is:
y = 3 x 2^x
We can check that this equation is correct by plugging in the coordinates:
When x = 2: y = 3 x 2^2 = 12
When x = 3: y = 3 x 2^3 = 24

Part of the graph of the function f(x) = (x – 1)(x + 7) is shown below.
Which statements about the function are true? Select three options.
The vertex of the function is at (–4,–15).
The vertex of the function is at (–3,–16).
The graph is increasing on the interval x > –3.
The graph is positive only on the intervals where x < –7 and where
x > 1.
The graph is negative on the interval x < –4.
Answer:
The vertex of the function is at (–3,–16)
The graph is increasing on the interval x > –3
The graph is positive only on the intervals where x < –7 and where
x > 1.
Step-by-step explanation:
The graph of \(f(x)=(x-1)(x+7)\) has clear zeroes at \(x=1\) and \(x=-7\), showing that \(f(x) > 0\) when \(x < -7\) and \(x > 1\). To determine where the vertex is, we can complete the square:
\(f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16\)
So, we can see the vertex is (-3,-16), meaning that where \(x > -3\), the function will be increasing on that interval

according to the given information we can say that the fraction of the area of the circle that is shaded is 1/4 or 0.25.
What is circle?Every point in a horizontal surface that is a certain distance above another point forms a circle (centre). It is a circle made out of point that are separated from each other in a horizontal direction as a result. At all angles, it is rotating symmetric about the centre. In the closed, two-dimensional plane of a circle, each pair of points is evenly separated from the "centre." A line that pierces the circle creates a specular symmetrical line. At all angles, it rotates symmetrically about the centre.
given,
If the circle is divided into two equal parts and one of them is shaded, then the shaded area is half of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/2 or 0.5.
If the circle is divided into four equal parts and one of them is shaded, then the shaded area is one-fourth of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/4 or 0.25.
Therefore, the answer depends on how many equal parts the circle is divided into and the number of shaded parts.

Systolic blood pressure readings are normally distributed with a mean of 121 and a standard deviation of 15. (A reading above 140 is considered to be high blood pressure). Find the percentage of people with blood pressure below 133.
The percentage of people with blood pressure below 133 is 78.81%.
First, we need to calculate the Z-score for the value 133 using the formula:
Z = (X - μ) / σ
where X is the value (133), μ is the mean (121), and σ is the standard deviation (15).
Z = (133 - 121) / 15
Z = 12 / 15
Z = 0.8
Next, we can use a standard normal distribution table or a calculator to find the area under the curve to the left of the Z-score 0.8.
Looking up the Z-score of 0.8 in the standard normal distribution table, we find that the area to the left of 0.8 is 0.7881.
Therefore, the percentage of people with blood pressure below 133 is 78.81%.
