Name the property the equation illustrates.
–2.1 • 1 = –2.1
Identity Property of Multiplication
Inverse Property of Multiplication
Multiplication Property of –1
Identity Property of Addition
Solution: The correct option is option first, i.e., [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.
Explanation:
The correct option is first option : Identity Property of Multiplication.
Reason for correct option:
According to the identity property of multiplication, the product of a number and the identity element is equal to that number. The identity element for multiplication is 1.
Let x be any real number, then by identity property of multiplication [tex]x\cdot1=x[/tex].
Therefore, [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.
Reason for incorrect option:
According to the inverse property of multiplication, the product of number and inverse is equal to 1. In the given equation the result is not 1.
In the given equation the number is multiplied by 1 instead of -1. So, multiplication property of -1 is not the correct answer.
In the given equation multiplication property is used and there is no need of any addition property.
Hence, only first option is correct and [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.

Write an algebraic expression to find the number of seconds in n minutes. Evaluate the expression for n = 20
Write an expression that represents "the product of 12 and n".
The expression 'the product of 12 and n' can be written as 12n in mathematics. The word 'product' refers to the result of multiplication, thus the phrase means 12 multiplied by n.
In mathematics, an expression that represents 'the product of 12 and n' would be written as 12n.
In this expression, 12 is a constant and n is a variable.
The expression is saying to multiply 12 by whatever value n has. For instance, if n is 2, the value of the expression 12n would be 24 because 12 times 2 equals 24.
The word 'product' in math usually refers to the result of multiplication.
Therefore, the phrase 'the product of 12 and n' means '12 multiplied by n'.

The graph of the equation of line y = - 14x + 74 is shown in figure.
What is Equation of line?
The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of line is,
y - 4 = - 14 (x - 5)
Now,
The simplify the equation of line as;
y - 4 = - 14 (x - 5)
y - 4 = - 14x + 70
Add 4 on both side, we get;
y - 4 + 4 = - 14x + 70 + 4
y = - 14x + 74
Thus, By comparing the slope form of the equation of line y = mx + b we get;
The slope of the line m = - 14
And, The y - intercept = 74
So, The graph of the equation of line y = - 14x + 74 is shown in figure.

need help with calculus...not just answer. worked out with explanation please
since the fence will be 3 sides, the length would be length minus 2 widths
so length = 1200 - 2x
area = length x width
width is x
area = (1200-2x)*x
= 1200x -2x^2
after doing the calculations x = 600 meters, width = 300 meters
How do you find square roots? Example: Square root of 441.
The basics ones, like 25 (5) are easy but is there a formula for higher numbers?
-_- please explain, not just answer the Example.
Final answer:
The square root is a value that produces a specified quantity when multiplied by itself. For perfect squares like 441, the square root is an integer like 21. For non-perfect squares or higher numbers, use a calculator or raise the number to the 0.5 power.
Explanation:
Finding Square Roots
Finding the square root of a number involves identifying a value that, when multiplied by itself, gives the original number. For perfect squares like 25, the square root is an integer (in this case, 5). However, for higher numbers, especially those that are not perfect squares, you may need to use a calculator or apply the long division method for finding square roots. Additionally, understanding the concept of exponents helps simplify square roots. For instance, raising a number to the power of 0.5 is the same as taking the square root:
x2 = √x
To find the square root of 441, recognize that it is a perfect square, as 21 multiplied by 21 results in 441. Therefore, √441 = 21. For more complex numbers, a calculator's square root function, or the y* button to raise the number to the 0.5 power can be used. If you're working with roots beyond square roots, such as fourth roots, you could raise the number to the power of 0.25 or take the square root twice sequentially.

The solution of the operations of the fractions are found as below.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
4. [tex]\frac{3}{4}[/tex] + [tex]\frac{1}{2}[/tex]
Make the denominator equal.
1/2 is equal to (1×2) / (2×2) = 2/4
[tex]\frac{3}{4}[/tex] + [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{4}[/tex] + [tex]\frac{2}{4}[/tex] = [tex]\frac{3+2}{4}[/tex] = [tex]\frac{5}{4}[/tex]
5. 2 [tex]\frac{3}{8}[/tex] + 1 [tex]\frac{1}{8}[/tex]
This in the form of mixed fraction.
Convert it into improper fraction first.
2 [tex]\frac{3}{8}[/tex] = (2 × 8 + 3) / 8 = 19/8
1 [tex]\frac{1}{8}[/tex] = (1 × 8 + 1) / 8 = 9/8
2 [tex]\frac{3}{8}[/tex] + 1 [tex]\frac{1}{8}[/tex] = 19/8 + 9/8 = 28/8 = 7/2
6. 5 [tex]\frac{2}{5}[/tex] - 3 [tex]\frac{7}{10}[/tex]
5 [tex]\frac{2}{5}[/tex] = (5 × 5 + 2) / 5 = 27/5
3 [tex]\frac{7}{10}[/tex] = (3 × 10 + 7) / 10 = 37/10
5 [tex]\frac{2}{5}[/tex] - 3 [tex]\frac{7}{10}[/tex] = 27/5 - 37/10
= 54/10 - 37/10
= 17/10
7. 5 [tex]\frac{1}{2}[/tex] × [tex]\frac{3}{11}[/tex]
5 [tex]\frac{1}{2}[/tex] = 11/2
5 [tex]\frac{1}{2}[/tex] × [tex]\frac{3}{11}[/tex] = [tex]\frac{11}{2}[/tex] × [tex]\frac{3}{11}[/tex]
= 3/2
8. [tex]\frac{5}{6}[/tex] ÷ [tex]\frac{1}{3}[/tex]
When dividing two fractions, the second term becomes reciprocal and the operation becomes multiplication.
[tex]\frac{5}{6}[/tex] ÷ [tex]\frac{1}{3}[/tex] = [tex]\frac{5}{6}[/tex] × [tex]\frac{3}{1}[/tex] = 5/2
Hence the solutions are found.
