In the diagram below, (5, 2) is the midpoint of a segment with one endpoint (-1, 8). What is the other endpoint of the segment? Show your work or explain how you find your answer.

Answer:approximatly -1.63092975357148

Step-by-step explanation:To solve the equation (1/2)^7x+1 = -9, we first need to get all the terms on one side of the equation by subtracting 1 from both sides. This gives us (1/2)^7x = -10.

Next, we need to get x by itself, so we take the log base 2 of both sides.

This gives us log base 2 of (1/2)^7x = log base 2 of -10.

The log base 2 of (1/2)^7 is -7, so we have -7x = log base 2 of -10

Finally, we divide both sides by -7 and get x = log base 2 of -10/-7

Using a calculator we can calculate this value which is approximatly -1.63092975357148

x = log base 2 of -10/-7 = -1.63092975357148

The money that a organisation earns in return for their labour or products is referred to as income.She make from each source last year $6000.

The money that a person or organisation earns in return for their labour or products is referred to as income.

Salary, rent, capital gains, company revenue, and income from other sources are a few typical sources of income. Understanding how each type of income is taxed is not always simple, and you may require an income tax calculator to do so.

Let t=teaching income, p=painting income, and b=book sales income.

t=p+6000 b=(t+p)/7 b+t+p=48000 (t+p)/7 +p+6000+p=48000 substitute (2p+6000)/7 + p+6000 + p = 48000 (2p+6000) + 7(p+6000) + 7p = 7*48000 multiply each side by 7 to eliminate the fraction.

substitution (2p+6000)/7 + p+6000 + p = 48000 (2p+6000) + 7(p+6000) + 7p = 7*48000

2p+6000+7p+42000+7p=336000

16p+48000=336000

16p=336000-48000

16p=288000 \s16p/16=288000/16

p=$18,000.

t=18000+6000

t=$24,000.

b=(24000+18000)/7

=42000/7

=$6000.

The relationship between x and y can be described based on the value of the sample correlation coefficient.

Sample covariance measures the degree to which two variables are linearly related and the direction of their linear relationship. The formula for sample covariance is:

[tex]Cov(x,y) = (1/(n-1)) * \Sigma(x-\bar x)(y- \bar y)[/tex] where,

The sample correlation coefficient, also known as Pearson's correlation coefficient, measures the degree to which two variables are linearly related and the direction of their linear relationship. It is a normalized version of the sample covariance, with a value between -1 and 1. The formula for the sample correlation coefficient is:

r = Cov(x,y) / (s1 * s2) where,  

To calculate the sample covariance and sample correlation coefficient, we need to have a sample of data containing the variables x and y. Once we have the data, we can calculate the sample means, and sample standard deviations, and then use the formulas above to calculate the sample covariance and sample correlation coefficient.

The relationship between x and y can be described based on the value of the sample correlation coefficient.

What is a graph ?

Graph can be defined as the visual representation of the given data using ordered pairs.

Graph of f(x)

You can read the y-intercept on the graph. It is the value of y-coordinate when x = 0; so ti is y = 6.

The axis of simmetry is the vertical line that split the graph into two symmetrical forms. That is the same that the vertical line that passes through the vertex. You can see that it is x = 2

Answer:

Step-by-step explanation:

Answer: If you take 15% off of 84.75, the new amount would be 71.8875. This can be calculated by multiplying 84.75 by 0.15 (15% written as a decimal), and then subtracting that result from 84.75.

The coordinates of the final image are

A'' (3, 2)

B'' (0, 2)

C'' (2, 3)

The coordinates of the preimage are A(2,3), B(2,0), and C(3,2)

The transformation rule for a 90 degrees clockwise rotation is

(x, y) → (y,-x)

hence we have

A(2,3), → (3,-2)

B(2,0) → (0,-2)

C(3,2) → (2,-3)

The transformation rule for reflection in the y axis is

(x, y) → (x,-y)

Step-by-step explanation:

To find the line of best fit, we can use the equation for a linear regression: y = mx + b, where y is the price, x is the weight in ounces, m is the slope of the line, and b is the y-intercept.

To estimate the price when the weight is 48 ounces, we can plug in x = 48 into the equation: y = mx + b, and solve for y.

The correlation coefficient, denoted by r, is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, with -1 indicating a perfect negative correlation, 0 indicating no correlation, and 1 indicating a perfect positive correlation.

In this case, the correlation coefficient means that how strong and direction of the relationship between the price and weight of cereal. A correlation coefficient of 1 means that there is a perfect positive correlation between the two variables, which means that as the weight of the cereal increases, so does the price. A correlation coefficient of -1 means that there is a perfect negative correlation between the two variables, which means that as the weight of the cereal increases, the price decreases. A correlation coefficient of 0 means that there is no correlation between the two variables, which means that there is no relationship between the weight of the cereal and the price.

For the sum of ages of Adam, Barry, and Charlie is 53 , Barry is 14 years old.

Number of brothers are three.

Adam, Barry and Charlie.

Let us consider 'x' years be the age of Barry.

Adam age is equal to (2x) years.

And Charlie age is equal to ( x - 3 )years.

Sum of their ages = 53

Substitute the value of Adam, Barry and Charlie age we get,

⇒ x + 2x + x - 3 = 53

⇒ 4x = 53 + 3

⇒ 4x = 56

⇒ x = 56 / 4

⇒ x = 14 years

Barry is  14 years old.

Adam = 2(14 )

          = 28 years

Charlie = 14 - 3

            = 11 years

Therefore, as per the information about the ages of Adam, Barry and Charlie , the Barry is 14 years old.

The missing angle measures in triangle ABC are 35.5° and 54.5°.

We know that,

In the right triangle ABC

∠A +∠B =90°   ( by complementary angles)

We find the measure of angle B.

we know that

[tex]tanB = \frac{opposite side angle B}{adjacent side angle B}[/tex]

According to the question,

Opposite side angle B= 7 in

Adjacent side angle B = 5in

So, [tex]tanB = \frac{7}{5}[/tex]

      [tex]B = arc tan(\frac{7}{5})[/tex]

      B = 54.5°

Then, we find the measure of angle A

A + B = 90°

 A = 90°-B

A = 90° -  54.5° ( using subtraction)

A = 35.5°

Answer:

y = -3x + 3

Step-by-step explanation:

the equation of a line in point-slope form is.

y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex])
y - (-6) = -3 (x - 3)

y+6 = -3x+9

Answer:

y = -3x+3

Step-by-step explanation:

Remember that y = mx+c

The slope is m aka the gradient and we know that that's -3.

So just chuck it into the equation:

y = -3x + c

We still have to find c (which is the y intercept)

So substitute the point (3,-6) into the equation

We will have: -6 = -3(3) +c

Once you do algebra you'll get 3=c

So substitute that back into the equation (without the point (3,-6) since we only need the equation)

y = -3x + 3

To calculate the amount of money in Roberto's savings account after 5 years, you can use the formula for simple interest:

I = Prt

Where:

I = Interest earned

P = Principal (original amount of money in the account)

r = Annual interest rate (expressed as a decimal)

t = Number of years

In this case, the principal is $250, the annual interest rate is 5% (or 0.05 as a decimal), and the number of years is 5.

So, you can plug these values into the formula:

I = 250 * 0.05 * 5

To find out the total amount of money in the account after 5 years, you need to add the interest to the principal:

250 + I = 250 + (250 * 0.05 * 5) = 250 + 62.5 = $312.5

Roberto's account will have $312.5 after 5 years.
