The coordinates of M, B, and D of a square with vertices A(-2,0) and C(6,4) where AC and BD diagonals intersect at M are M(2,2), B(6,-8), and D(-2,8), respectively.

To locate the coordinates of M, we will first find the midpoint of AC, which is also the middle of the square. The midpoint of AC is ((-2+6)/2, (0+4)/2), which simplifies to (2,2).

Hence, M is in the middle of the square. To locate the length of a side of the square, we are able to use the distance formula.

The distance between a and C is √((6-(-2))² + (4-0)²), which simplifies to √(64+16), that is 8. Accordingly, each side of the square has a length of 8. Given that M is in the middle of the square, we can use this truth to discover the coordinates of B and D.

Because B and D are on opposite sides of M, their x-coordinates and y-coordinates should differ via 8. Seeing that a is at (-2,0), B needs to be 8 units to the proper and 8 units down, so B is at (6, -8). Further, on the grounds that c is at (6,4), D should be 8 gadgets to the left and 8 units up, so d is at (-2, 8).

There are 1200 ways for the boy's mother to get 3 arcades and 2 sports games from his collection.

We can use the combination formula which is:

nCr = n! / (r! * (n-r)!)

where n is the total number of items, r is the number of items to choose, and ! denotes the factorial function.

In this case, we want to choose 3 arcade games and 2 sports games from a collection of 10 arcade games and 5 sports games. So, we have:

Number of ways to choose 3 arcade games from 10 arcade games = 10C3 = 120

Number of ways to choose 2 sports games from 5 sports games = 5C2 = 10

Part A: The equation to represent the problem is 259.99 + 3.75r = 436.24. The variable 'r' represents the number of times Derek used one of the racquetball courts.

Part B

Derek used a racquetball court 46.93 times

Part A: The equation to represent the problem is: 259.99 + 3.75r = 436.24. The “r” represents the number of times Derek used one of the racquetball courts. 259.99 is the yearly membership fee and the 3.75 is the cost of each time Derek used a racquetball court. 436.24 is the total amount Derek paid for the entire year at the health club.

Part B: To solve the equation, we need to isolate “r” on one side of the equation. To do this, we need to subtract 259.99 from both sides of the equation. We then get 3.75r = 176.25. We divide both sides by 3.75 to get r = 46.93. This means that Derek used a racquetball court 46.93 times.

Amanda can spend 9/48 of her budget on entertainment, which can be simplified to 3/16.

In mathematics, an expression is a combination of numbers, symbols, and/or operators that represents a mathematical quantity or relationship. Expressions can be composed of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, and division, as well as functions and other mathematical constructs.

The fractions of Amanda's budget allocated to each category are:

Venue: 5/24

Invitations: 1/16

Food: 1/4

Decorations: 3/16

The sum of these fractions is:

5/24 + 1/16 + 1/4 + 3/16 = 15/48 + 3/48 + 12/48 + 9/48 = 39/48

This means that Amanda has allocated 39/48 of her budget to these four categories. To find out what fraction of her budget she can spend on entertainment, we need to subtract this fraction from 1 (since the remaining fraction is what she can spend on entertainment):

1 - 39/48 = 9/48

Therefore, Amanda can spend 9/48 of her budget on entertainment, which can be simplified to 3/16.

The final charge of the spheres when they are touching after calculated using Coulomb's law , is 1.24 * 10^-6 C

According to the given information, two charged spheres with charges |q1| > |q2| attract each other with a force of magnitude 90.4 mn when separated by a distance of 4.64 m. When the spheres are brought together until they are touching, they attain the same final charge q.

We can use Coulomb's law to find the final charge q. Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's law is expressed as:

F = k * (q1 * q2) / r^2

Where F is the force between the charged particles, k is Coulomb's constant (8.99 * 10^9 N*m^2/C^2), q1 and q2 are the charges of the particles, and r is the distance between them.

We can rearrange the equation to solve for q:

q = sqrt(F * r^2 / k)

Plugging in the given values:

q = sqrt(90.4 * 10^-6 N * (4.64 m)^2 / (8.99 * 10^9 N*m^2/C^2))

q = 1.24 * 10^-6 C

Therefore, the final charge of the spheres when they are touching is 1.24 * 10^-6 C

ln(y) = -0.544x + 1.099

The logarithmic equation that relates x and y is given by ln(y) = -0.544x + 1.099. To get this equation, the given table of values is considered.Let's first find the value of "a" in the general logarithmic equation, which is y = a ln(x). We use the given table of values to get this value. When x = 1, y = 1, and so a ln(1) = 1, which implies that a = 1. Hence, the equation becomes y = ln(x).Now, we need to convert this to an equation in terms of y and x. That is, we need to find ln(y) in terms of x. To do this, we substitute y for x in the equation y = ln(x). That is, we get ln(y) = ln(x).Now, we substitute the given values of x and y in this equation to get the required logarithmic equation. That is, we have:ln(y) = -0.544x + 1.099 (rounded to three decimal places). Therefore, the logarithmic equation that relates x and y is ln(y) = -0.544x + 1.099.

The equation that models the relationship between the models to show Ethan's employee benefits is y = 14 + 3(x - 1).

The number of paid vacation days Ethan earned was 35 paid vacation days .

Ethan will reach the maximum number of paid vacation days in 7 years.

Let x represent the number of years he has worked for this employer and y represent the number of paid vacation days he has earned.

The equation that models the relationship between x (years worked) and y (paid vacation days earned) is:

y = 14 + 3(x - 1)

Using the equation from part a, we can find out how many paid vacation days Ethan has earned after eight years:

y = 14 + 3(8 - 1)

y = 14 + 3(7)

y = 14 + 21

y = 35

To determine when Ethan will reach the maximum number of paid vacation days, we can set y equal to 30 and solve for x:

30 = 14 + 3(x - 1)

16 = 3(x - 1)

16/3 = x - 1

x = 16/3 + 1

x = 16/3 + 3/3

Using Algebraic equations, the dimensions of the frame are 6in: 9 in.

The word "area" refers to a free space. A shape's length and width are used to compute its area. Unidimensional length is expressed in terms of feet (ft), yards (yd), inches (in), etc. But a shape's area is a two-dimensional measurement. Hence, it is expressed in square units such as square inches (in2), square feet (ft 2), square yards (yd2), etc.

Given, the area of the rectangular picture frame is 54 in².

length of the frame is 3 feet longer than the width,

Let us assume width = x

length of the frame will be = x + 3,

Area of rectangle = length × breadth

⇒ 54 = (x) (x + 3)

⇒ 54 = x² + 3x

Now, factorizing the given equation,

x² + 3x - 54

x² + 9x - 6x - 54

x(x + 9) -6 (x + 9)

(x + 9) (x - 6)

The value of x will be x = -9 and x = 6

As the negative length of the rectangle is not possible, we will consider, x = 6 and width = 9,

Answer:

To compare the slopes of Function A and Function B, we need to find the slope of each function.

Function A: y = 104x

The slope of a linear function in the form y = mx + b is equal to the coefficient of x, which is 104 in this case. Therefore, the slope of Function A is 104.

Function B: y = -x + 7

The slope of a linear function in the form y = mx + b is equal to the coefficient of x, which is -1 in this case. Therefore, the slope of Function B is -1.

Since 104 is greater than -1, the statement "The slope of Function A is greater than the slope of Function B" is true.

Therefore, the answer is: The slope of Function A is greater than the slope of Function B.

The mean of Y is -5/4 and the variance of Y is 144.

In statistics, the mean is a measure οf central tendency that represents the average οf a set οf data. It is alsο knοwn as the arithmetic mean. The mean is calculated by adding up all the values in the dataset and dividing the sum by the tοtal number οf values. It is οften used tο describe the typical οr average value in a set οf data.

Variance is a statistical measure that describes hοw much the values in a set οf data vary frοm the average value οr mean. It measures the spread οr dispersiοn οf the data pοints arοund the mean.

In the given questiοn,

Tο find the mean and variance οf the randοm variable Y, we need tο use the fοrmulas fοr the expected value and variance οf a functiοn οf a randοm variable:

The expected value (mean) of Y is given by:

E(Y) = E(3X - 2) = 3E(X) - 2

The variance of Y is given by:

Var(Y) = Var(3X - 2) = 9Var(X)

To find E(X), we need to integrate the density function f(x) over all possible values of X:

E(X) = ∫0∞ x f(x) dx

= ∫0∞ x (1/4)[tex]\rm e^{(-x/4)[/tex]dx

This integral can be solved using integration by parts, with u = x and dv/dx = (1/4)[tex]\rm e^{(-x/4)[/tex] dx.

Integrating by parts, we get:

E(X) = [-x/4 [tex]\rm e^{(-x/4)[/tex]]_0∞ + ∫0∞ (1/4)[tex]\rm e^{(-x/4)[/tex] dx

= [0 + (1/4)]/1 + [0]

= 1/4.

Therefore, the expected value of Y is:

E(Y) = 3E(X) - 2 = 3(1/4) - 2 = -5/4.

To find Var(X), we can use the formula for the variance of an exponential distribution, which is:

Var(X) = (1/λ²) = (4²) = 16.

Therefore, the variance of Y is:

Var(Y) = 9Var(X) = 9(16)

= 144.

Therefore, the mean of Y is -5/4 and the variance of Y is 144.

The mean of Y is 10 minutes, and the variance of Y is 144 minutes squared.

What is integration?

Integration is a mathematical operation that is the reverse of differentiation. Integration involves finding an antiderivative or indefinite integral of a function.

To find the mean and variance of Y, we will first need to find the mean and variance of X.

Mean of X:

The mean of X is given by:

E(X) = integral from 0 to infinity of xf(x) dx

E(X) = integral from 0 to infinity of x * 1/4 e^(-x/4) dx

Using integration by parts with u = x and dv = e^(-x/4) dx, we can evaluate this integral to get:

E(X) = 4

Variance of X:

The variance of X is given by:

Var(X) = E(X^2) - [E(X)]^2

We will first need to find E(X^2). Using integration by parts again, we can evaluate this integral as:

E(X^2) = integral from 0 to infinity of x^2 * 1/4 e^(-x/4) dx

E(X^2) = 32

Therefore, the variance of X is:

Var(X) = E(X^2) - [E(X)]^2

Var(X) = 32 - 16

Var(X) = 16

Now, we can use the formula for the mean and variance of a linear transformation of a random variable to find the mean and variance of Y.

Mean of Y:

The mean of Y is given by:

E(Y) = E(3X - 2)

E(Y) = 3E(X) - 2

E(Y) = 10

Variance of Y:

The variance of Y is given by:

Var(Y) = Var(3X - 2)

Var(Y) = 9Var(X)

Var(Y) = 144

Therefore, the mean of Y is 10 minutes, and the variance of Y is 144 minutes squared.

Assuming that David sold the stock at $10 per stock today, then, we will agree that he bought the Oracle stock yesterday at a price of approximately $9.89 per share.

A share, also known as a stock or equity, is a unit of ownership in a corporation. Stock investments provide investors with returns in the form of dividends and capital gains. The higher the expected returns, the more shares an investor owns.

Let the price at which David bought each share of Oracle stock yesterday be x. Then, his total cost for buying 200 shares would be: 200x

Similarly, his total revenue for selling 200 shares at $10 per share today would be:
