Hi Math do please I don’t want fail :(

When a point is rotated, it must be rotated over a line.

The coordinates of the image is (-13, 10)

The point is given as:

\((x,y) = (13,10)\)

The rule for reflection across the x-axis is:

\((x,y) \to (x,-y)\)

So, we have:

\((13,10) \to (13,-10)\)

Hence, the coordinates of the image is (-13, 10)

None of the options is correct

Let's calculate the total cost of all the items purchased by the computer club:

Cost of 14 portfolios = 14 * $24.59

Cost of 14 binders = 14 * $12.92

Cost of 14 school sweatshirts = 14 * $14.00

Cost of 14 music cases = 14 * $1.25

Cost of 14 phone cases = 14 * $1.99

Cost of 14 mouse pads = 14 * $2.14

Total cost of all items = Cost of 14 portfolios + Cost of 14 binders + Cost of 14 school sweatshirts + Cost of 14 music cases + Cost of 14 phone cases + Cost of 14 mouse pads

Plugging in the given values:

Total cost of all items = (14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14)

Now, the computer club will pay for 40% of the total cost. To calculate this, we can multiply the total cost by 40% (or 0.40):

Club's payment = 0.40 * Total cost of all items

The remaining cost will be divided equally among the 14 members:

Remaining cost per member = (Total cost of all items - Club's payment) / 14

Plugging in the values and calculating:

Club's payment = 0.40 * ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14))

Remaining cost per member = ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14) - Club's payment) / 14

So, each member of the computer club will owe the calculated value for "Remaining cost per member".

Hope this is good

Therefore, the radius of convergence, r, is 1.

To find the radius of convergence, we can use the ratio test. The series is given by:

\(∑ [n=1 to ∞] ((-1)^n * n^5 * x^n) / (7^n)\)

Applying the ratio test, we evaluate the limit:

\(lim (n→∞) |((-1)^(n+1) * (n+1)^5 * x^(n+1)) / (7^(n+1))| / |((-1)^n * n^5 * x^n) / (7^n)|\)

Simplifying the expression, we have:

\(lim (n→∞) |(-1)^(n+1) * (n+1)^5 * x^(n+1) * 7^n| / |((-1)^n * n^5 * x^n) * 7^(n+1)|\)

Taking the absolute values and canceling common terms, we get:

\(lim (n→∞) |(n+1)^5 * x^(n+1)| / |n^5 * x^n * 7|\)

Next, we can simplify the expression further:

\(lim (n→∞) |(n+1)^5 * x| / |n^5 * x^n * 7|\)

As n approaches infinity, the dominant term in the numerator and denominator is n^5, so we can disregard the other terms:

\(lim (n→∞) |(n+1)^5 * x| / |n^5|\)

The limit can be evaluated as:

\(lim (n→∞) |(1 + 1/n)^5 * x|\)

Since we want the limit to be less than 1 for convergence, we have:

\(|(1 + 1/n)^5 * x| < 1\)

Taking the absolute value, we get:

\((1 + 1/n)^5 * |x| < 1\)

As n approaches infinity, the term \((1 + 1/n)^5\) approaches 1, so we are left with:

|x| < 1

This means that the series converges for values of x within the interval (-1, 1).

The forecast value for time period 2 is 210, and the forecast error is -110 when the actual value is 100. Option B

To calculate the forecast value for time period 2, we substitute W = 2 into the regression equation:

y = 200 + W + 2W^2

= 200 + 2 + 2(2^2)

= 200 + 2 + 2(4)

= 200 + 2 + 8

= 210

Therefore, the forecast value for time period 2 is 210.

To calculate the forecast error, we compare the forecasted value with the actual value for time period 2. Given that the actual value is 100, the forecast error can be calculated as the difference between the actual value and the forecast value:

Forecast error = Actual value - Forecast value

= 100 - 210

= -110

Hence, the forecast error is -110.

Therefore, the correct answer is:

Forecast value = 210; forecast error is -110. So Option B is correct.

To provide a 95% confidence interval for the mean of a population, the confidence coefficient is the value that corresponds to the desired level of confidence in the standard normal distribution.

The correct answer is option a: 1.96. When constructing a confidence interval for the mean, we typically assume that the population follows a normal distribution or use the Central Limit Theorem if the sample size is large. A 95% confidence interval means that we want to be 95% confident that the true population mean falls within the interval. The confidence coefficient is the critical value corresponding to the desired level of confidence. In the case of a 95% confidence interval, we need to find the critical value that leaves 2.5% of the area in each tail of the standard normal distribution.

Using a standard normal distribution table or statistical software, we find that the critical value for a 95% confidence interval is approximately 1.96. This means that we can construct a confidence interval by taking the sample mean and adding/subtracting 1.96 times the standard error.

Therefore, the confidence coefficient for a 95% confidence interval is 1.96. This value is commonly used in practice to determine the range of values within which we can be 95% confident that the true population mean lies.

If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, then each missing measure fm=88 and ce=44.

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.

Step 1: Identify each vertex's coordinates.

Step 2: Add together and divide by three all the x values from the coordinates of the three vertices.

Step 3: Add together all the y values from the three vertices and divide the result by three.

Step 4: The centroid coordinate is determined from the values collected in stages 2 and 3.

the ratio of both segments is 2:1.

where;

am = 44 and dm = 23

the longer segment is double of shorter one:

2*23 = 46.

Therefore,

fm = 46-23

= <<23=23>>23

now finding ce:

= 2*44

The difference quotient of \(f(x) = x^2 - 6x + 5\) is is 2x - 6 + h.

To find the difference quotient for the function \(f(x) = x^2 - 6x + 5\), we need to evaluate

(f(x + h) - f(x)) / h, where h is not equal to 0.

First, let's find f(x + h):

\(f(x + h) = (x + h)^2 - 6(x + h) + 5\)

\(= x^2 + 2hx + h^2 - 6x - 6h + 5\)

\(= x^2 - 6x + 5 + 2hx - 6h + h^2\)

Now, we can substitute the values of f(x + h) and f(x) into the difference quotient:

\((f(x + h) - f(x)) / h = ((x^2 - 6x + 5 + 2hx - 6h + h^2) - (x^2 - 6x + 5)) / h\)

= (2hx - 6h + h^2) / h

= 2x - 6 + h

A person who placed a $5 bet on a horse with 11 to 2 odds and that horse won the Preakness race would win $27.50 in addition to having their $5 wager returned.

when odds are expressed in a ratio such as 11 to 2, it means that for every 11 chances the horse will lose, there are 2 chances it will win. This can also be expressed as a probability of 2/13 (2 chances out of a total of 13 possible outcomes).

To calculate the potential payout, you simply multiply the amount of the bet by the odds ratio and then add the original bet back in. In this case, $5 multiplied by 11/2 equals $27.50, which is the amount the person would win if the horse they bet on won the race.

To prove: angle BOC = 90°+1/2angle A

Proof: Using angle sum property in ∆BOC, we obtain

angle 1+ angle 2 + angle BOC = 180°...(I)

Using angle sum property in∆ABC, we obtain

angle A + angle B + angle C = 180°

or, angle A + 2(angle 1) + 2(angle 2) = 180° [Since BO and CO are the bisectors of angle ABC and angle ACB respectively, then, angle B = 2(angle 1) and angle C = 2(angle 2)]

or, angle A/2 + angle 1 + angle 2 = 90° [Dividing both sides by 2]

or, angle 1 + angle 2 = 90° - angle A/2 ...(ii)

Substituting this value of angle 1 + angle 2 in (i), we get

Adam Vinatieri made 14 field goals and 7 extra points.

Given that,

a field goal is 3 points and the field goal after a touchdown is only 1 point.

Adam Vinatieri made 21 field goals and extra point kicks for 49 points.

Let x be the number of field goals and y be the extra point kicks.

So we get,

x + y = 21 -------------(1)

3x + y = 49 -----------(2)

Subtracting equation (1) from equation (2),

2x = 28

 x = 14

putting the value of x in equation (1),

14 + y = 21

       y = 7

Therefore Adam Vinatieri made 14 field goals and 7 extra points.

If the log was 2 feet long, that is 2 * 12 = 24 inches, so the snake was longer than the log, at a total of 25 inches.

Height is a measurement of vertical extension (how "tall" something or someone is), vertical position, or both (how "high" a point is). For instance, "That building is 50 meters high," or "The height of an airplane while it is in flight is roughly 10,000 meters."

Height is defined in mathematics as the vertical distance separating an object's top from its base. On occasion, it is referred to as "height". In coordinate geometry, an object's height is calculated along the y-axis and is referred to as height. Following are a few mathematical examples of height.

If Emilee could see 15 inches of the snake and two-fifths of the snake was behind the log, then the total length of the snake must be 15 / (1 - 2/5) = 15 / (3/5) = 15 * (5/3) = 25 inches.

The given parameterization x(t) y(t) 3t 6 is equivalent to the one we found since 3t is the same as z(t) and 6 is the same as the starting value of z(t), which is 3.

To find the parameterization of the line l in r3 that passes through the points (0,1,3) and (8,7,9), we can use the following formula:

x(t) = x1 + (x2 - x1)t
y(t) = y1 + (y2 - y1)t
z(t) = z1 + (z2 - z1)t

where x1, y1, and z1 are the coordinates of the first point and x2, y2, and z2 are the coordinates of the second point.

Using this formula, we have:

x(t) = 0 + (8 - 0)t = 8t
y(t) = 1 + (7 - 1)t = 1 + 6t
z(t) = 3 + (9 - 3)t = 3 + 6t

Therefore, the parameterization of the line l in r3 is:

x(t) = 8t
y(t) = 1 + 6t
z(t) = 3 + 6t

Note that the given parameterization x(t) y(t) 3t 6 is equivalent to the one we found since 3t is the same as z(t) and 6 is the same as the starting value of z(t), which is 3.
