Where are the asymptotes for the following function located?
f (x) = startfraction 7 over x squared minus 2 x minus 24 endfraction
The asymptotes for the given function f(x) = 7/(x^2-2x-24) are located at
x = -3 and x = 8.
The asymptotes of a function are the lines that the graph approaches, but never touches as it continues to infinity. In the given function, f(x) = 7/(x^2-2x-24), the asymptotes are located at x = -3 and x = 8.
To find the asymptotes of a function, you first need to factor the denominator of the function. In this case, the denominator is[tex]x^2-2x-24,[/tex]which can be factored into (x+3)(x-8). This means that there are two potential zeroes in the denominator, x=-3 and x=8. These two points are the two asymptotes of the graph of the given function.
To explain further, the two asymptotes divide the x-axis into three intervals. On the interval (-infinity, -3), the graph of the function will approach negative infinity as x approaches -3 from the left. On the interval (-3, 8), the graph of the function will approach positive infinity as x approaches 8 from the right. On the interval (8, infinity), the graph of the function will approach negative infinity as x approaches 8 from the right.
In summary, the asymptotes for the given function f(x) = 7/(x^2-2x-24) are located at x = -3 and x = 8.

1. Find the length of arc PRQ: Show your work.
Answer:
The length of arc PRQ is 16.7 in.
Step-by-step explanation:
Given;r = 8 inθ = 120°So,
arc length = 2πr × (θ/360)
arc length = 2(3.14)(8) × (120/360)
arc length = 2(3.14)(8) × (120/360)
arc length = 50.24 × (1/3)
arc length = 16.7 inches
Thus, The length of arc PRQ is 16.7 in.

Step 1
To demonstrate how to solve a radical equation, let's use the following equation as an example:
Determine the domain and range for the function below.
Answer:
Domain: (-∞, ∞); Range: [1, ∞)
Step-by-step explanation:
Domain is the set/interval of x-values that the function spans while the range is the set or interval of y-values that the function spans.
Domain
We can see that the arrows point towards negative and positive infinity for x and also see there are no holes or asymptotes for this graph. Therefore, the domain is (-∞, ∞) or {x | x is any real number}
Range
We can see that the arrows both point towards infinity for y-values and that the lowest y-value this graph touches is y = 1 (inclusive, meaning this y-value is included in the range). Thus, the range is [1, ∞) or {y | y ≥ 1}
How do you determine the relationship between the volume of a rectangular prism and pyramid?
The relationship between the volume of a rectangular prism and pyramid is defined as that the pyramid takes up 1/3 of the volume of a prism.
Here we need to identify the relationship between the volume of a rectangular prism and pyramid.
As we all know that the volume of rectangle prism is written as,
=> Volume of a prism = (area of base) * height
Now, let us consider the volume of a pyramid that the pyramid takes up 1/3 of the volume of a prism when their bases and height are equal.
So, here the volume of a pyramid is 1/3 multiplied by the volume of a prism.
Then we get the volume of pyramid is written as,
Volume of a pyramid = 1/3 (area of the base) * height

Graph the line through the given point with the given slope.
(0, 5), m = - 5
(basically what coordinate points would there be?)
Answer:
The equation would be
y =-5x + 5
Step-by-step explanation:
Use the x of 0 from the point given (0,5)
Use the y of 5 from the point given (0,5)
Use the slope that is given: -5
Use all of the above to solve for the y-intercept (b).
y = mx + b
5 = -5(0) + b
5 = 0 + b
5 = b
y =mx + b
y = -5x + 5
In the graph, the line crosses the y axis at (0,5) . The is the y -intercept or the "b" of the equation.
From that points move down 5 and one to the right. This is the slope. Once we have two points we can draw a line.
Clark's rule is a formula used to determine pediatric doses of over the counter medicine.
The formula says
The weight of a child divided by 150 multiplied by the adult dose is the same as the child dose
if an adult dose of acetaminophen is 1,000 mg and a child weighs less than 90 pounds, what is
the recommended range of doses?
A. x≤ 600
B. x ≥ 600
C. 500
D. 500 ≤x≤ 600
500 ≤x≤ 600 is the recommended range of doses. Typically, a phase I or early phase II clinical trial involves dose range.
How to calculate doses ?To solve this problem using Clark's rule, we need to determine the range of pediatric doses for a child who weighs less than 90 pounds and for whom the adult dose is 1,000 mg.
A mathematical formula known as Clark's rule is used in medicine to determine the right dosage of medication for patients aged 2 to 17 depending on their weight and the recommended adult dose.
First, we can use the formula provided to calculate the child dose:
Child dose = (Weight of child / 150) * Adult dose
Since the weight of the child is less than 90 pounds, we can set the weight of the child to the minimum value in the range, which is 50 pounds. This gives us:
Child dose = (50 / 150) * 1000 mg
= 333.33 mg
Next, we can set the weight of the child to the maximum value in the range, which is 89 pounds. This gives us:
Child dose = (89 / 150) * 1000 mg
= 593.33 mg
Therefore, the recommended range of doses for a child who weighs less than 90 pounds and for whom the adult dose is 1,000 mg is 500 mg ≤ x ≤ 600 mg.
So, the correct answer is D. 500 ≤x≤ 600.

What does Squaring mean ?
In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.
When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

Evaluation:
We are required to find the equivalent fraction here. When simplifying 16/64, we divide both sides by 16:
16 ÷ 16 = 1
64 ÷ 16 = 4
16/64 in its simplest form is 1/4. When we multiply both the numerator and denominator by 2, we will find that:
1/4 = 2/8

Answer:
Brand A Forks $0.08, Brand B Forks $0.06, Better Buy is Brand B
Step-by-step explanation:
Unit price is price per unit (in this case, forks)
You need to find the $ for 1 fork for Brand A and B, since they have different unit prices.
total price/units = price/unit
Brand A: $1.97/25 forks = $0.0788 (rounded up is $0.08)
Brand B: $2.98/48 forks = $0.06208 (rounded up is $0.06)
