The difference between depths in January and July is equal to: D. 16 feet.
What is an absolute value function?An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols
How to determine the difference between depths?In order to determine the difference between depths, we would calculate the magnitude of the depth for each of the month.
For January, we have:
January depth = 20 - 6
January depth = 14 feet.
For July, we have:
July depth = 20 - 22
July depth = -2 feet.
Now, we can calculate the difference between depths in January and July:
Difference = 14 - (-2)
Difference = 14 + 2
Difference = 16 feet.

Is there any value(s) of the domain of 2 2=8 that passes the vertical line test?
The value of domain that will pass the vertical line test is ±2√2.
What is a domain?The collection of inputs a function can accept is referred to as the domain of the function in mathematics. [tex]dom(f)[/tex] is a common way to refer to it, with f standing for the function.
To be more specific, the domain of f is X when the function [tex]f:X--Y[/tex] is specified. The domain of a function is not a characteristic of it, but rather an element of the definition in contemporary mathematical terminology.
The function f can be represented as a graph in the Cartesian coordinate system in the particular case where X and Y are both subsets of. A projection of the function's graph onto the graph's x-axis in this instance serves as the domain's representation.
Explanation:
Finding the domain,
[tex]x^2+ y^2[/tex] = 8
[tex]\sqrt{x^2} + \sqrt{y^2}[/tex] = √8
x + y = ±2√2
So, the domain is ±2√2.

yolanda spends 8 2⁄3 hours per month playing soccer. approximately how many hours does she play soccer in a year? (there are twelve months in a year.)
The total time she spends playing soccer in a year is 104 hours, which is calculated using the concept of fraction and arithmetic operations.
What is a fraction?
Any numerical number which does not represent the entire quantity is called a fraction. It depicts a part or portion of something. It is generally written in the form of numerator by denominator.
Calculation of the total time Yolanda spends playing soccer
Given that Yolanda plays soccer for 8 ⅔ hours in a month
Firstly, convert the hours in mixed fraction to improper fraction i.e. 8 ⅔ = (8 × 3 + 2) / 3
= 26 / 3
Now, we need to calculate the no. of hours she played in a year, which is done by multiplying the obtained improper fraction with 12
i.e. (26 / 3) × 12
= 104 hours
Hence, Yolanda spends 104 hours a year playing soccer.

To enter an arcade, Linus has to pay a $5 fee. In addition, every arcade game costs an additional $0.25 to play one round. The relationship between the amount of Linus' money spent, or C, and the number of rounds of arcade games played, or r, can be modeled by the equation C=0.25r+5.
The amount of Linus's money spent on 200 rounds of arcade game is $55.
The given question is incomplete, so
Lets suppose that Linus has played 200 round of arcade game and now we will need to determine the amount of Linus's money spent on 200 rounds of arcade game.
Entrance fee of an arcade = $5
Additional cost to play one round = $0.25
With the help of given equation ( C=0.25r+5 ) we will determine the amount of Linus's money spent on 200 rounds of arcade game.
'C' = The relationship between the amount of Linus' money spent
'r' = The number of rounds of arcade games played
Let's solve the equation now,
As we know that r is number of rounds Linus has played which is 200 rounds.
So, C = 0.25r+5
C = 0.25 × 200 + 5
C = 50 + 5
C = $55
Hence, we got that Linus has spent total $55 on 200 rounds of arcade game.

Harry buys 3 granola bars for $5. Sidney buys 9 granola bars for $15 what is the constant of proportionality
The constant of proportionality is 5/3.
What is the constant of proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. The constant of proportionality may also be referred to by the terms constant ratio, constant rate, unit rate, constant variation, or even change rate.
Let the constant of proportionality is k.
Harry buys 3 granola bars for $ 5. So, we can write it as
3 × k = 5
k = 5/3
To Check:
Sidney buys 9 granola bars for $ 15, we can write it as
9 × k = 15
Put k= 5/3 in the equation
9 × 5/3 = 15

the length of a rectangle is twice as long as he width. the perimetter of the rectangle is 72 in. what tare thte length and width of this rectangle
For the given rectangle, having perimeter = 72, the length of the rectangle will be 12 cm and breadth will be 24 cm
What is the perimeter of rectangle?The overall length of the outline determines a shape's perimeter in two dimensions. We sum the lengths of all four corners of a rectangle to determine its perimeter.
Since the opposing sides of a rectangle are always equal, we must determine the length and breadth of the rectangle in order to determine its perimeter. The rectangle's perimeter may be expressed as the product of its length and breadth times two. As a linear measurement, the perimeter can be expressed in meters, centimeters, inches, feet, etc.
Given,
perimeter = 72
let us assume length = x
The breadth will thus be = 2x.
Now that these numbers have been plugged in, we may solve the equation for x.
perimeter of rectangle = 2 (L + B)
72 = 2 (x + 2x)
72 = 2 (3x)
72 = 6x
x = 72/6
x = 12

an equilateral triangle has sides of equal length. determine whether the triangle with vertices 1-1, -12, 12, 32, 1-4, 32 is equilateral.
The triangle with the given vertices (-1, -1), (2, 3), and (-4, 3) is not an equilateral triangle.
What is an equilateral triangle?An equilateral triangle can be defined as a special type of triangle that has equal side lengths and all of its three (3) interior angles are equal.
In order to determine whether the triangle with the given vertices is an equilateral triangle, we would apply the distance formula to calculate the length of each side of this triangle as follows:
Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
For the vertices (-1, -1) and (2, 3), we have;
A = √[(2 - (-1))² + (3 - (-1))²]
A = √[(2 + 1)² + (3 + 1)²]
A = √[3² + 4²]
A = √[9 + 16]
A = √25
A = 5 units.
For the vertices (2, 3) and (-4, 3), we have;
B = √[(-4 - 2)² + (3 - 3)²]
B = √[-6² + 0²]
B = √[36 + 0]
B = √36
B = 6 units.
For the vertices (-1, -1) and (-4, 3), we have;
C = √[(-4 - (-1))² + (3 - (-1))²]
C = √[(-4 + 1)² + (3 + 1)²]
C = √[-3² + 4²]
C = √[9 + 16]
C = √25
C = 5 units.
Therefore, the triangle with the given vertices is not an equilateral triangle because C = A ≠ B.
