5.424 ≈ 5.420
Step-by-step explanation:5.424
↓4 = Tenth
↓2 = Hundredth
↓4 = Thousandth
The value of number after rounded to the nearest hundredth is, 5.42
In rounding a number into the nearest hundredth,
We look at the tenths place digit, If tenths place digit is 0, 1, 2, 3 or 4,
Then the number rounded to previous hundredth,
While, if the tenths place digit is 5, 6, 7, 8 or 9,
Then the number is rounded to next hundredth,
Here, the given number is,
⇒ 5.424
Here, Tenths place digit = 2,
Hence, it would be rounded to previous hundred,
Which is, 5.424 ≈ 5.42

¿De que manera las propiedades de las operaciones de los números racionales las podemos emplear en la estimación de presupuesto?
Answer:
La pregunta no está completa. Explicaré las propiedades de funcionamiento de los números racionales.
Explanation:
Las principales propiedades de los números racionales son:
- Propiedad de cierre
- Propiedad de conmutatividad
- Propiedad asociativa
- Propiedad distributiva
La propiedad de cierre establece que para dos números racionales cualesquiera xey, x + y, x-y, x * y, y x / y también será un número racional.
La propiedad de conmutatividad establece que para dos números racionales cualesquiera xey, x + y = x + y; x - y ≠ y - x; x * y = y * x; x / y ≠ y / x.
La propiedad asociativa establece que para cualesquiera tres números racionales dados x, y y z, (x + y) + zyx + (y + z) son iguales.
La propiedad distributiva establece que para tres números cualesquiera x, y y z, x × (y + z) = (x × y) + (x × z).

Answer:
The answer is: Integers, and Rational Numbers.
Step-by-step explanation:
the number -4 belongs to the subsets of real numbers: Integers and Rational numbers.
The number -4 belongs to the following subsets of real numbers:
1. Integers: Integers include all positive and negative whole numbers, as well as zero. Since -4 is a negative whole number, it is an integer.
2. Whole numbers: Whole numbers include all non-negative integers. Since -4 is negative, it is not a whole number.
3. Natural numbers: Natural numbers include all positive integers. Since -4 is negative, it is not a natural number.
4. Rational numbers: Rational numbers include all numbers that can be expressed as a ratio of two integers, where the denominator is not zero. -4 can be expressed as -4/1, where -4 is an integer and 1 is also an integer. Therefore, -4 is a rational number.
In conclusion, the number -4 belongs to the subsets of real numbers: Integers and Rational numbers.

solve the equation below
for the indicated variable
1/3ab^2=6 (solve for a)
Answer:
a=18/b2
Step-by-step explanation:
The required equation for the indicated variable is a = 18/b² which is solved for a.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given the equation for the indicated variable as
⇒ 1/3ab² = 6
Multiply by 3 both sides of the above equation,
⇒ ab² = 6×3
⇒ ab² = 18
Divide by b² into both sides of the equation, and we get
⇒ a = 18/b²
Therefore, the required equation for the indicated variable is a = 18/b².

Make t the subject of the formula 2(d – t) = 4t + 7
Step-by-step explanation:
2(d-t)=4t +7
open the bracket
2d - 2t =4t +7
collect like terms
2d-7=4t +2t
2d-7=6t
divide both sides by 6
2d-t/6=6t/6
T=2d-t/6
Answer:
t = (2d-7)/6
Step-by-step explanation:
2(d – t) = 4t + 7
Distribute
2d-2t=4t+7
Add 2t to each side
2d-2t+2t=4t+2t+7
2d = 6t+7
Subtract 7 from each side
2d-7 = 6t
Divide by 6
(2d-7)/6 = t

For the constant function v(x) = 1, which statement describes the additive and multiplicative inverses? Both inverses are equal to v(x). Neither inverse is equal to v(x). The additive inverse is equal to v(x), but the multiplicative inverse is not. The multiplicative inverse is equal to v(x), but the additive inverse is not.
Answer:
The multiplicative inverse is equal to v(x), but the additive inverse is not.
Step-by-step explanation:
The multiplicative inverse is equals to v(x) but the additive inverse is not.
What is additive inverse?Additive inverse is a number which on getting added to the original number results in zero.
For example, 5 - 5 = 0
⇒ -5 is the additive inverse of 5.
What is multiplicative inverse?Multiplicative inverse of a number is a value which when multiplied by the original number results in 1.
For example
[tex]5 (\frac{1}{5} )= 1[/tex]
⇒ [tex]\frac{1}{5}[/tex] is the multiplicative inverse of 5.
According to the given question.
We have a function
v(x) = 1
Let the additive inverse of 1 is x.
⇒ 1 + x = 0
⇒ x = -1.
Hence, the additive inverse of 1 is -1.
Let the multiplicative inverse of 1 is y.
⇒ 1 × y = 1
⇒ y = 1/1
⇒ y = 1
Hence, the multiplicative inverse of 1 is 1.
From the above calculation we can see that, the multiplicative inverse is equals to v(x) but the additive inverse is not.
Thus last option is correct.

find all values of c such that the domain of the following function is the set of all real numbers
f(x) = (x + 7) / (x^2 + 2cx + 14)
Answer:
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
Step-by-step explanation:
For the function to have a domain of all reals, the denominator cannot have a value of zero. x^2 + 2cx + 14 will not have zero as a root if it has no real solutions. A quadratic equation has no solutions when the discriminant is negative.
b^2 - 4ac < 0
(2c)^2 - 4(1)(14) < 0
4c^2 - 56 < 0
4c^2 < 56
c^2 < 14
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
The domain of the function, f(x) = (x + 7) / (x^2 + 2cx + 14) is the set of all real numbers for the value of c as [tex]-\sqrt{14} < c < \sqrt{14}[/tex] .
Domain of a function are the values that a function can take that is the set of all possible inputs.
Given the following function:
[tex]f(x)=\dfrac{x+7}{x^2+2cx+14}[/tex]
For the real number domain of the given function, the denominator must be a non-zero term. Because, if the denominator is zero then the function will result in an undefined number which does not lie in the real number domain.
For denominator to be non zero, we have to find the value of x which is not the solution of the equation of denominator.
x²+2cx+14≠0
Such value of x can be determined using discriminant.
d<0, then no real solution exists.
d=b²-4ac
Here a=1, b=2c, c=14
d=4c²-4x14
d=4c²-56
d<0
4c²-56<0
4c²<56
c²<14
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
Thus, [tex]-\sqrt{14} < c < \sqrt{14}[/tex] is such that the domain of the function is the set of all real numbers.
