and |q1| > |q2| attract each other with a force of magnitude 90.4 mn when separated by a distance of 4.64 m . the spheres are then brought together until they are touching, enabling the spheres to attain the same final charge q.
Answers
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

Answers
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.

In his free time, Gary spends 9 hours per week on the Internet and 9 hours per week playing video games. If Gary has five hours of free time per day, approximately what percent of his free time is spent on the Internet and playing video games?
Answers
Gary has 5 hours of free time per day, which is equivalent to 35 hours of free time per week (since there are 7 days in a week).
The total time Gary spends on the Internet and playing video games per week is 9 + 9 = 18 hours.
To find the percentage of his free time spent on these activities, we divide the total time spent on them by the total free time available, then multiply by 100:
(18 / 35) x 100 = 51.43%
So approximately 51.43% of Gary's free time is spent on the Internet and playing video games.

The empirical rule, also known as the three-sigma rule or the 68-95-99.7 rule, provides a quick estimate of the spread of data in a normal distribution given the mean and standard deviation. Specifically, the empirical rule states that for a normal distribution:
68% of the data will fall within one standard deviation of the mean.
95% of the data will fall within two standard deviations of the mean.
Almost all (99.7%) of the data will fall within three standard deviations of the mean.
The empirical rule is used as a rough gauge of normality. When a number of data points fall outside the three standard deviation range, it can indicate non-normal distributions.

The area of a rectangular picture frame is 54 in2. The length of the frame is 3 feet
longer than the width. What are the dimensions of the frame?
O 3 in; 18 in
O 6 in; 9 in
O4 in; 7 in
O9 in; 12 in
Answers
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,
∴ The length of the rectangle = 6 inch,
Width of the rectangle will be = 6 + 3 = 9 inch.

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

Amanda can spend 9/48 of her budget on entertainment, which can be simplified to 3/16.
What is expression ?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.
According to the given information: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):

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.
How to find the paid vacation days ?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
x = 19/3
x = 7

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.

A quadratic function y=f(x) is plotted on a graph and the vertex of the resulting parabola
(−4,−5). What is the vertex of the function defined as g(x)= f(-x)−4?
Answers
Answer:
(-2,6)
Step-by-step explanation:
y=f(x) has vertex (-4,6)
g(x)=-f(x-2) shifts the graph 2 units to the right, not to the left, and the graph is reflected over the x-axis
therefore the vertex is (-2,6) and the reflection over the x-axis has no affect on the vertex

Answers
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.

David bought 200 shares of Oracle stock yesterday and sold it today. His profit was $22. 0. At what price did he buy the stock yesterday?
Answers
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.
How do we calculate the price he bought the stock yesterday?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:
= 200*($10)
= $2000
His profit was $22, so we can set up the equation which is $2000 - 200x = $22.
Simplifying and solving for x, we get:
$1978 = 200x
x = $1971/200
x = $9.89.

ABCD is a square. A is the point (-2,0)and C is the point (6,4). AC and BD are diagonals of the square which intersect at M.
Find the coordinates of M, B, and D
Answers
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).
