The correct symbol that Ari should write between the two sets of numbers is C. =.
When Ari writes "2 + 4" on the left-hand side of his paper and then writes "6" to the right of the expression, he is indicating that the sum of 2 and 4 is 6. The symbol "=" is used to denote equality, meaning that the value on the left side of the equation is the same as the value on the right side. In this case, the sum of 2 and 4 indeed equals 6, so the complete equation should be written as:
[tex]\[ 2 + 4 = 6 \][/tex]
This shows that the operation of adding 2 and 4 results in the number 6, which is a true statement. Therefore, the correct answer to the question is option C, the equals sign "=".

The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
The given equation is
[tex]y=\frac{5}{2}x-10[/tex]
It means the slope of the line is 5/2 and y-intercept is -10.
The slope of two parallel lines is same. So, the slope of required line is 5/2.
The equation of required line is
[tex]y=\frac{5}{2}x+b[/tex]
It is given that the line passes through the point (-6,-29).
[tex](-29)=\frac{5}{2}(-6)+b[/tex]
[tex]-29=-15+b[/tex]
[tex]-29+15=+b[/tex]
[tex]-14=b[/tex]
The y-intercept of required line is -14. So the equation of required line is
[tex]y=\frac{5}{2}x-14[/tex]
Therefore the correct option is B.

How does finding the square root of a number compare to finidng the cubic root of a number?
Final answer:
Square rooting and cube rooting are processes to find a number that, when raised to the second or third power respectively, equals the original number. Square roots are related to squares, and cube roots are related to cubes; both functions are essential in solving various mathematical problems, including equilibrium and Pythagorean Theorem problems.
Explanation:
Finding the square root of a number is the process of determining a number which, when multiplied by itself, gives the original number. For example, the square root of 25 is 5, because 5 squared (5²) is 25. This can be expressed using exponents as x¹⁄₂ = √x.
On the other hand, finding the cube root of a number involves determining a number which, when multiplied by itself twice (or cubed), results in the original number. For instance, the cube root of 27 is 3, since 3 cubed (3³) equals 27. The formula for a simple equilibrium problem that involves cubic roots is a³ = M₁ × P², where you would then find the cube root of the result to solve for 'a'.
Both operations are inverse functions: square rooting is the inverse of squaring, and cube rooting is the inverse of cubing. When dealing with equilibrium problems or Pythagorean Theorem applications, it's important to know how to perform these operations, often requiring a calculator. Make sure you are comfortable with your calculator's functions for these operations, or seek assistance from your instructor if needed.
Write a function g in terms of f so that the statement is true.
The graph of g is a reflection in the y-axis of the graph of f
g(x)=
The function g(x) in terms of f(x) that represents a reflection in the y-axis is g(x) = -f(x).
Explanation:The function g(x) in terms of f(x) that represents a reflection in the y-axis is g(x) = -f(x).
To reflect a point across the y-axis, we change the sign of the x-coordinate. So, to reflect the graph of f(x) across the y-axis, we need to change the sign of f(x). This can be achieved by multiplying f(x) by -1, giving us g(x) = -f(x).
For example, if f(x) = 2x+3, then g(x) = -(2x+3) = -2x-3.

The function g(x) that represents a reflection in the y-axis is g(x) = -f(x).
Explanation:The function g(x) in terms of f(x) that represents a reflection in the y-axis is g(x) = -f(x).
To reflect a graph in the y-axis, we replace each x-coordinate with its opposite (negative value) while keeping the y-coordinate unchanged. In this case, since g is the reflection of f in the y-axis, the function g(x) will have the same y-values as f(x), but the x-values will be their negatives.
For example, if f(x) = 2x + 3, then g(x) = -f(x) would be g(x) = -2x - 3, where the graph of g(x) is the reflection of f(x) across the y-axis.

The dimensions of the carpet are 54 inches in length and 34 inches in width. This was determined by setting up and solving the perimeter equation for a rectangle, after which we calculated the length by adding 20 to the width.
To determine the dimensions of a rectangular Persian carpet with a perimeter of 176 inches where the length is 20 inches more than the width, first, let's let the width be represented by w inches. The length will then be w + 20 inches. The perimeter of a rectangle is calculated by adding together twice the width and twice the length (P = 2w + 2l).
The formula with the given values will look like this:
176 = 2w + 2(w + 20)
Simplifying this equation gives us the width and subsequently the length:
176 = 2w + 2w + 40
176 = 4w + 40
136 = 4w
w = 34
So, the width of the carpet is 34 inches. To find the length, we add 20 inches to the width:
Length = w + 20 = 34 + 20 = 54 inches
Therefore, the dimensions of the carpet are 54 inches in length and 34 inches in width.

A box has a rectangular base with a length of 3x + 2 and width of 2x - 2, and the base has a perimeter of 60 centimeters. If the height of the box is x, what is the volume of the box?
The volume of the box is determined by finding the value of x from the perimeter equation, substituting it back into the expressions for length and width, and finally multiplying the dimensions with the height. Calculating these steps, the volume of the box is 1200 cm³.
Explanation:To find the volume of a box, we multiply its length, width, and height. The student has provided the length as 3x + 2, the width as 2x - 2, and the height as x. We also know the perimeter of the base is 60 centimeters.
First, we calculate the perimeter of the base, which is 2(length + width). Hence, we set up the equation: 2(3x + 2 + 2x - 2) = 60. Simplifying this, we get 2(5x) = 60, therefore x = 6 cm.
Second, we substitute x into the expressions for length and width to get the actual dimensions of the box base: length 3(6) + 2 = 20 cm, and width 2(6) - 2 = 10 cm.
Finally, we calculate the volume of the box as length × width × height = 20 cm × 10 cm × 6 cm = 1200 cm³.
