In mathematics, self-contained state actions are known as k-adic. Monadic, dyadic, and triadic are specific cases of k-adic functions.
Explanation:In mathematics, self-contained state actions are known as k-adic. The term 'k-adic' refers to functions that take k inputs and produce a single output. Monadic, dyadic, and triadic are specific cases of k-adic functions, where k is 1, 2, and 3, respectively. Thus, it typically refers to a numeral or number system that is based on the value of k, which can be any positive integer.
In such systems, numbers are represented using a base of k, and each digit holds its own place value. K-adic expansions are useful in number theory and algebraic number theory, providing insights into number properties and relationships in various mathematical contexts.

A new machine can make 10,000 aluminum cans three times faster than an older machine. with both machines working, 10,000 cans can be made in 9 hours. how long would it take the new machine, working alone, to make the 10,000 cans?
Since the new machine is three times faster, it takes (12 hours) / 3 = 4 hours for the new machine to make 10,000 cans alone.
Let's denote the time it takes the older machine to make 10,000 cans as "t" hours.
The new machine can make 10,000 cans three times faster than the older machine, which means it takes "t/3" hours for the new machine to make 10,000 cans.
When both machines are working together, they can make 10,000 cans in 9 hours.
Now, we can set up an equation based on the work rates of the two machines:
Work rate of the older machine + Work rate of the new machine = Combined work rate
The work rate is the amount of work (number of cans made) per unit of time (hours).
For the older machine:
Work rate of the older machine = 10,000 cans / t hours
For the new machine:
Work rate of the new machine = 10,000 cans / (t/3) hours
Combined work rate when both machines work together:
Combined work rate = 10,000 cans / 9 hours
Now, the equation becomes:
10,000 cans / t hours + 10,000 cans / (t/3) hours = 10,000 cans / 9 hours
To solve for "t," we can start by finding a common denominator for the fractions on the left side of the equation:
t/3 is the same as (1/3)t. So the equation becomes:
10,000 cans / t hours + 10,000 cans / (1/3)t hours = 10,000 cans / 9 hours
Now, to combine the fractions, we find the common denominator, which is 3t:
(3t * 10,000 cans) / (3t * t hours) + (t * 10,000 cans) / (3t * t hours) = 10,000 cans / 9 hours
(30,000t + 10,000t) / (3t^2 hours) = 10,000 cans / 9 hours
Combine the terms on the left side of the equation:
40,000t / (3t^2 hours) = 10,000 cans / 9 hours
Now, cross-multiply to solve for "t":
40,000t * 9 hours = 10,000 cans * 3t^2 hours
360,000t hours = 30,000t^2 hours
Now, rearrange the equation:
30,000t^2 - 360,000t hours = 0
Divide by 30,000t to simplify the equation:
t - 12 = 0
Now, solve for "t":
t = 12 hours
Therefore, it takes the older machine 12 hours to make 10,000 cans.

Identify a semicircle that contains C.
A.ABC
B.AC
C.CB
D. ACB
Answer: The correct option is (D). ACB.
Step-by-step explanation: We are given to identify a semi-circle that contains the point 'C'.
As shown in the figure, AB is the diameter of the circle with center 'O'.
So, there are two congruent semi-circles made by the diameter AB.
The point 'C' lies on the upper semi-circle made by the diameter AB.
Since the upper semi-circle contains the point 'C', so it is named as the semi-circle ACB.
Thus, the semi-circle ACB contains the point 'C'.
Option (D) is correct.

For a fixed amount of a gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. At a pressure of 30 pounds per square inch (psi), a gas has a volume of 600 in.3. Which function can be used to model the volume of the gas y, in cubic inches, when the pressure is x psi?
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]
Let
x-------> the pressure in PSI
y------> the volume of the gas in cubic inches
In this problem we have the point [tex](30,600)[/tex]
so
[tex]x=30\ psi\\y=600\ in^{3}[/tex]
Find the constant k
[tex]y*x=k[/tex]
substitute the values of x and y
[tex]600*30=k[/tex]
[tex]k=18,000\ lb*in[/tex]
the equation is
[tex]y=18,000/x[/tex]
therefore
the answer is
[tex]y=18,000/x[/tex]
Answer:
[tex]y=\frac{18000}{x}[/tex]
Step-by-step explanation:
Let the volume of gas be y
Let the pressure be x
Since we are given that the volume of the gas is inversely proportional to its pressure.
⇒[tex]y \propto \frac{1}{x}[/tex]
Let the proportionality be k
So, [tex]y=\frac{k}{x}[/tex] ---A
Now we are given that At a pressure of 30 pounds per square inch (psi), a gas has a volume of 600 cubic inches
So, substitute x = 30
y = 600
[tex]600=\frac{k}{30}[/tex]
[tex]600 \times 30=k[/tex]
[tex]18000 =k[/tex]
Substitute the value of k in A
So, [tex]y=\frac{18000}{x}[/tex]
Hence function can be used to model the volume of the gas y, in cubic inches, when the pressure is x psi is [tex]y=\frac{18000}{x}[/tex]

Three times the difference of a number x and seven is twenty-three minus the sum of three times a number x and two. what is the value of x?
The required value of x is 7.
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now the given statement is,
Three times the difference of a number x and seven is twenty-three minus the sum of three times a number x and two.
So converting them into numerical form,
the difference of a number x and seven = x - 7
∴ Three times the difference of a number x and seven = 3(x - 7)
Similarly,
the sum of three times a number x and two = 3x + 2
∴ Twenty-three minus the sum of three times a number x = 23 - (3x + 2)
Therefore, the required equation is,
3(x - 7) = 23 - (3x + 2)
Expanding the brackets we get,
3x - 21 = 23 - 3x - 2
or, 3x - 21 = 21 - 3x
Taking alike terms together,
3x + 3x = 21 + 21
or, 6x = 42
Dividing both side by 6 we get,
x = 7
which is the required value of x.
Thus, The required value of x is 7.

An isosceles triangle with equal sides of 5 inches and a base of 6 inches is inscribed in a circle. What is the radius, in inches, of the circle? Express your answer as a mixed number.
To find the radius of the circle inscribed in the isosceles triangle, we can use the formula for the inradius of a triangle. The inradius is given by the formula: inradius = (area of the triangle) / (semiperimeter of the triangle). First, we need to find the area and semiperimeter of the triangle. Then, we can calculate the inradius and find the radius of the circle.
Explanation:To find the radius of the circle inscribed in the isosceles triangle, we can use the formula for the inradius of a triangle. The inradius is given by the formula:
inradius = (area of the triangle) / (semiperimeter of the triangle)
First, we need to find the area of the triangle. Since it is an isosceles triangle with equal sides of 5 inches, we can split it into two congruent right triangles. The height of each right triangle can be found using the Pythagorean theorem:
height = sqrt(5^2 - (6/2)^2) = sqrt(25 - 9) = sqrt(16) = 4 inches
Now, we can find the area of the triangle:
area = (1/2) * base * height = (1/2) * 6 * 4 = 12 square inches
Next, we need to find the semiperimeter of the triangle:
semiperimeter = (5 + 5 + 6) / 2 = 16 inches
Finally, we can calculate the inradius:
inradius = 12 / 16 = 3/4 inches
Therefore, the radius of the circle is 3/4 inches.
