By using coordinates in rectangular form and Pythagorean theorem, we conclude that the point (x, y) = (√11 / 6, 5 / 6) is on the unit circle as its norm is equal to 1.
Is a given point on Cartesian plane lying on the unit circle?
We find a point in rectangular form, that is, a point of the form (x, y). Unit circles are circles with a radius 1 that are commonly used to represent graphically angles. The given point is in the units if and only if its norm is equal to 1. The norm of the point is determined by using the Pythagorean theorem:
r = √[(√11 / 6)² + (5 / 6)²]
r = √[(11 / 36) + (25 / 36)]
r = √(36 / 36)
r = √1
r = 1

The area of an animal pen is 30 square feet. what are the legnths of the pen's sides if the pen has each given shape?
L = 1.3245 is the legnths of the pen's sides .
What is area and perimeter?
Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
The equation for perimeter is 2L + W = 30 ( I'm assuming that the shed takes up one of the Widths, but you can use the Length if you want, it doesn't matter.)
So W = 30 - 2L.
Area = L x W = L (30 - 2L) = 30L - 2L^2.
This is a quadratic equation, easily graphed as a parabola, with a maximum point at L = 1.3245 .

2. Use what you know about the properties of operations to rewrite the expression 7.4.1.5 = commutative
Natural number multiplication is commutative.
What are the properties of operations?Whole numbers can be multiplied together commutatively.Whole number multiplication is associative.Whole number division distributes over addition.The identity for multiplying whole numbers is 1, or 1.According to the commutative property, altering the order of the elements has no impact on the final result. Commutative's fundamental term is commute or exchange.According to the associative property, altering how the elements are grouped has no impact on the final output. Because humans frequently rearrange the groupings of elements while multiplying numbers to simplify issues, this characteristic strongly relates to the commutative property.We can basically spread out the elements thanks to the distributive principle, making it simpler to work with the numbers. When multiplying mentally, this is a common technique.Although multiplication properties might appear difficult, our students can surely master them with scaffolded help.The given number is commutative as -

Durante un entrenamiento, un ciclista da una vuelta a una pista circular en 105 segundos, mientras que otro tarda 60 segundos. Si ambos inician sus recorridos juntos, ¿en cuántos segundos será la próxima vez que coincidan en el punto de inicio?
Los ciclistas se encuentran aproximadamente 140 segundos después de partir.
¿En cuanto tiempo se encuentran dos ciclistas que se mueve a distintas rapideces constantes por primera vez?
En este problema asumimos que cada ciclista se mueve a rapidez constante, de modo que la rapidez angular de cada uno se define como sigue:
ω = 2π / T (1)
Donde:
ω - Rapidez angular, en radianes por segundo.T - Período, en segundos.A su vez, la posición de cada ciclista es descrita por las siguientes dos ecuaciones paramétricas:
x / R = cos ωt (2)
y / R = sin ωt (3)
Donde:
x, y - Coordenadas del ciclista.R - Radio de la pista circular.Primero, determinar la rapidez angular de cada ciclista:
ω₁ = 2π / 105 s
ω₁ ≈ 0.060 rad / s
ω₂ = 2π / 60 s
ω₂ ≈ 0.105 rad / s
Segundo, procedemos a graficar cada función paramétrica y determinamos el primer punto de intersección. Los resultados se encuentran en las imágenes adjuntas. Nótese que las curvas verde y púrpura se basan en la ecuación (2), mientras las curvas azul y rojo lo son de la ecuación (3).
Los dos ciclistas se encuentran por primera vez si las cuatro ecuaciones tienen el mismo valor t. En consecuencia, los ciclistas se encuentran aproximadamente 140 segundos después de partir.

The grade level is treated as categorical when a principal wants to know the number of students from each grade will be participating in a performance.
Variables can be classified into quantitative and categorical. Quantitative variables are those which carry numerical values. Even though a person's grade in school is generally identified by a number, it is a categorical variable. Categorical variables classify data into different groups as the grade level. The grade level categorizes students into different grades and each grade level represents a particular grade only.
Any variable which is partly qualitative and represents groups of data are called categorical variables. Also grade level is ordinal. An example of a situation in which grade level is treated as categorical is when a principal wants to know how many students from each grade will be participating in a performance.

The sum of three consecutive even integers is 72 let ex represent the first integer X plus to represent the second integer and X +4 represent the third furniture which equation can be used to find the first energy
Answer:
see explanation
Step-by-step explanation:
the 3 consecutive even integers are x , x + 2 and x + 4 , then their sum is
x + x + 2 + x + 4 = 72 , that is
3x + 6 = 72 ( subtract 6 from both sides )
3x = 66 ( divide both sides by 3 )
x = 22
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the 3 consecutive even integers are 22, 24 , 26

An internet service provider is implementing a new program based on the number of connected devices in each household. Currently, customers are charged a flat rate of $175 per month. The new plan would charge a flat rate of $94 plus an additional $4.50 per device connected to the network. Find the number of devices, x, for which the cost of the new plan is less than the cost of the current plan
The device numbers should be less than 18.
Given, internet service provider is charging a rate of $175 per month.
The new plan would charge $94 plus an additional $4.50 per device connected to the network.
we need to find the number of devices for which the cost of the new plan is less than the cost of the current plan.
old plan = $175
New plan = $94 plus $4.50 per device
let us suppose 'x' devices can be connected.
so, 94 ₊ 4.5x < 175
4.5x < 175 ₋ 94
4.5x < 81
x < 81/4.5
x < 18
less than 18.
Hence there should be less than 18 devices connected for the new plan.

What is a function?In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.
This ultimately implies that, a function typically shows the relationship between input values and output values of a data set, as well as showing how the elements in a table are paired (mapped).
When x = 1, the function f(x) is given by:
f(x) = 2x − 3
f(1) = 2(1) − 3
f(1) = 2 - 3
f(1) = -1.
Therefore, the function g(x) = f(3x) = 3 × -1 = -3.
When x = 2, the function f(x) is given by:
f(x) = 2x − 3
f(2) = 2(2) − 3
f(2) = 4 - 3
f(2) = 1.
Therefore, the function g(x) = f(3x) = 3 × 1 = 3.
When x = 3, the function f(x) is given by:
f(x) = 2x − 3
f(3) = 2(3) − 3
f(3) = 6 - 3
f(3) = 3.
Therefore, the function g(x) = f(3x) = 3 × 3 = 9.
In conclusion, the table which represents the function g(x) is as follows:

Step-by-step explanation:
Slope-intercept form :
y=mx+c
[tex]x - 3y = 9 \\ - 3y = - x + 9 \\ \frac{ - 3y}{ - 3} = \frac{ - x}{ - 3} + \frac{9}{ - 3} [/tex]

Write the equation of the line in slope-intercept form.
It has a coefficient of m = -1 and passes through the point (9, 4).
Answer:
y=-x+13
Step-by-step explanation:
m=-1
m is slope
point is (9, 4)
first use point slope equation
y-y1=m(x-x1)
y-9=-1(x-4)
distribute
y-9=-x+4
isolate the y variable
y=-x+13
What is the slope of the line that passes through the points(−4,2) and (−5,0)?
Step-by-step explanation:
the slope is (y coordinate change / x coordinate change) when going from one point on the line to another.
the direction does not matter, but it is essential that once a direction is picked for one coordinate, we use the same one then also for the other.
I prefer to go from left to right, so (-5, 0) to (-4, 2) :
x changes by +1 (from -5 to -4).
y changes by +2 (from 0 to 2).
so, the slope is +2/+1 = 2/1 = 2.

twice the larger of two consecutive integers is equal to fifteen less than three times the smaller
The larger of the two integers is 18 and the smaller integer is 17.
Integers are collection of whole numbers and negative numbers. Integers are not fractional numbers or decimal. Some examples of integers are -5,-25,0,13,9 .
Let us consider the smaller integer be x.
As the integers are consecutive, the larger integer is (x+1).
Now according to the given condition:
Twice the large integer=2(x+1)
15 less than the 3 times the smaller integer=3x-15
Now the value of these two expressions is equal.
Therefore: [tex]2(x+1)=3x+-15[/tex]
Solving the above equation to find the value of x:
[tex]or,2(x+1)=3x-15\\or,2x+2=3x-15\\or,2x-3x=-15-2\\or,-x=-17\\or,x=17[/tex]
Therefore the smaller integer is 17.
Larger integer(x+1) : 17+1=18
Therefore the integers are 17 and 18.

What is the Volume of a Rectangular Prism?The volume of a rectangular prism = (length)(width)(height).
1. Part A:
Length of the rectangular prism crate = 2.5 ft
Width = 1.7 ft
Height = 2 ft
Volume of the rectangular prism crate = (2.5)(1.7)(2)
Volume of the rectangular prism crate = 8.5 ft³
2/3 of the volume of the rectangular prism crate = 2/3(8.5) = 5.7 ft³
Part B:
Amount of space the dog will occupy = volume = (length)(width)(height).
Length = 2 ft
Height = 1 2/3 = 1.7 ft
Width = 3/4 = 0.75 ft
Amount of space the dog will occupy = volume = (2)(0.75)(1.7)
Amount of space the dog will occupy = volume = 2.55 ft³
The space the dog will occupy is less than 2/3 of the space of the crate, therefore, Josiah should buy the medium crate.
