The number of elements in set A is n = 12 elements of the set A is given by A = { -24 , -22 , -20 , -18 , -16 , -14 , -12 , -10 , -8 , -6 , -4 , -2 }

The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.

Given data ,

Let the set notation be represented as S

Now , the value of S is

S = {x|x is an even, negative integer and x > - 25}

Now , the value of the set A is given by all the numbers greater than -25 which are negative and even

So , A = { -24 , -22 , -20 , -18 , -16 , -14 , -12 , -10 , -8 , -6 , -4 , -2 }

The number of elements in set A = 12 elements

Therefore , the value of n = 12 elements

Hence , the set A = { -24 , -22 , -20 , -18 , -16 , -14 , -12 , -10 , -8 , -6 , -4 , -2 }

I wont give an explanation this time sorry I don't feel like it but just so you know I got this answer right so trust me.

The value of k will make V = x + k/x have a relative minimum at x = 3 is k = 9

A relative minimum of a function is the minimum value of the function in a particular interval.

Since we have the function  V = x + k/x. We desire to find the value of k that will make V = x + k/x have a relative minimum at x = 3

So, to find the relative minimum of V, we differentiate with respect to x and equate to zero.

So, V = x + k/x

dV/dx = d(x + k/x)/dx

= dx/dx + kd(1/x)/dx

= 1 - k/x²

Equating dV/dx to zero, we have that

dV/dx = 0

⇒ 1 - k/x² = 0

1 = k/x²

k = x²

For a relative minimum at x = 3, substitute x = 3 into the equation. So, we have that

k = x²

= 3²

= 9

So, k = 9

A variable is anything that may be altered in the context of an experiment or mathematical idea. A single symbol is frequently used to denote a variable. Generic symbols for variables are the letters x, y, and z. Variables are qualities with a wide range of values that may be investigated. These include characteristics like height, age, wealth, place of birth, academic standing, and kind of residence, to mention a few. The two primary groups of variables can be separated using numerical and categorical approaches.

The linear equation that gives the rule for the given table  x 0 1 2 3 y 0 2 4 6 is y = 2x.

A linear equation is an equation of a straight line in the form of y = mx + b, where m represents the slope of the line, and b represents the y-intercept.

The slope of the linear equation can be found by calculating the change in y over the change in x:

slope=(y2 - y1) / (x2 - x1)

Taking (x1,y1) = (0,0) and (x2,y2) = (3,6),

slope=(6 - 0) / (3 - 0)

        = 2

So slope of the linear equation is 2.

Next, we can use the point-slope form of the linear equation to find the equation of the line:

y - y1 = m(x - x1)

Taking (x1,y1) = (0,0) and m = 2,

y - 0 = 2(x - 0)

Out of the 15 children:

5 are only children, so they have 0 siblings each.

3 have 1 sibling each, so there are 3 * 1 = 3 siblings in total.

4 have 2 siblings each, so there are 4 * 2 = 8 siblings in total.

If Jenny has 50 square tiles and arranges them in a rectangular array with 4 rows, then she would have a total of 48 tiles, with 2 tiles left over.

If Jenny arranges the tiles in a rectangular array with 4 rows, this means each row will have 50/4 = 12.5 tiles. However, since we cannot have half a tile, we need to round down to the nearest whole number, which is 12.

Therefore, each row will have 12 tiles, and the total number of tiles used will be 4 x 12 = 48. To find out how many tiles are left over, we need to subtract the total number of tiles used from the original number of tiles: 50 - 48 = 2. So, there will be 2 tiles left over.

What are asymptotes ?

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.

An asymptote of the curve y = f(x) or in the implicit form: f(x,y) = 0 is a straight line such that the distance between the curve and the straight line lends to zero when the points on the curve approach infinity.

There are three types of asymptotes namely:

1) Vertical Asymptotes

2) Horizontal Asymptotes

3) Oblique Asymptotes

The point to note is that the distance between the curve and the asymptote tends to be zero as it moves to infinity or -infinity.

Answer:

x = 2 (True)

Step-by-step explanation:

This can be resolved with d = 25 miles by multiplying equation both sides by

If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:

15 = (3/5) * d

To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:

15 * (5/3) = d

Simplifying the expression on the left side, we get:

25 = d

Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.

In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:

15 = (3/5) * d

Which can be solved for d by multiplying both sides by 5/3, giving:

d = 25 miles

In conclusion, assuming that Jen has driven 15 miles, which is 3/5 of the entire trip, the equation that can be used to determine the whole distance d is:

15 = (3/5) * d

The solution to the system of equations is x = 6 and y = 2.

The system of equations can also be solved using the elimination method.

We are aware that a system of linear equations is a collection of two or more equations with at least two unknown variables. Finding the answers to the unknown variables in a system of equations is the process of solving a linear equation. There are numerous ways to identify the answers to the unknown variables. These include the cross-multiplication method, elimination method, substitution method, and graphic method.

from the question:

A system of equations can be solved in a variety of methods, including substitution, elimination, and matrices. I'll apply the substitution technique here:

x = 8 - y is the result of the first equation.

We can solve for y by substituting this expression for x in the second equation:

-x + 4y = 2

-(8 - y) + 4y = 2 (substituting x = 8 - y)

-8 + 5y = 2 (simplifying)

5y = 10 (adding 8 to both sides)

y = 2 (dividing by 5)

Knowing y, we can now use this quantity to solve one of the initial equations to determine x:

x + y = 8

x + 2 = 8 (substituting y = 2)

x = 6 (subtracting 2 from both sides)

Hence, x = 6 and y = 2 are the answers to the system of equations.

Answer:

$638.42

Step-by-step explanation:

First, we need to calculate the sale price of the tablet computer after the 14% discount is applied. To do this, we can multiply the original price by 0.86 (1 - 0.14), which gives:

Sale price = $707 x 0.86 = $608.02

Next, we need to add the sales tax to the sale price. To do this, we can multiply the sale price by 0.05 (5%), which gives:

Sales tax = $608.02 x 0.05 = $30.40

Finally, we can find the total cost of the tablet computer by adding the sale price and the sales tax, which gives:

Total cost = $608.02 + $30.40 = $638.42

Therefore, the total cost of the tablet computer with the discount and sales tax included is $638.42.

The constant of proportionality between the side length and the perimeter of the equilateral triangle would be = 3.

The constant of proportionality is defined as the constant value that exists between two variables that are in a direct proportional relationship to each other.

Therefore, the constant of proportionality which is the constant value existing between the two variables= 3.
