Step-by-step explanation:

The equation of the circle with center at (3,-4) that passes through (-1,-4) is (x - 3)²+ (y + 4)² = 16

The equation of a circle with center (a, b) and radius r is given by:

(x - a)² + (y - b)² = r²

We are given that the center of the circle is (3, -4), so we can substitute a = 3 and b = -4 in the above equation to get:

(x - 3)² + (y + 4)² = r²

We also know that the circle passes through the point (-1, -4).

Substituting this point into the above equation, we get:

(-1 - 3)²+ (-4 + 4)² = r²

16 = r²

r = 4

Hence, the equation of the circle with center at (3,-4) that passes through (-1,-4) is (x - 3)²+ (y + 4)² = 16

Required error is the perimeter of the triangle is 60 cm, not 66 cm as Alfonso said.

What is perimeter of a triangle?

The perimeter of a triangle is the total length of the three sides of the triangle. It is a fundamental geometric concept that is important in many applications, including architecture, engineering, and construction.

To calculate the perimeter of a triangle, you simply add up the lengths of its three sides. This is expressed by the following formula,

Perimeter = side a + side b + side c

where "a," "b," and "c" are the lengths of the three sides of the triangle.

Here Alfonso's error is that he added the three side lengths incorrectly. The correct way to find the perimeter of a triangle is to add up all three sides.

In this case, the three side lengths are 22 cm, 11 cm, and 27 cm. Adding them up, we get,

22 cm + 11 cm + 27 cm = 60 cm

Therefore, the perimeter of the triangle is 60 cm, not 66 cm as Alfonso said.

Answer:

11x + 2y

Step-by-step explanation:

Expand the equation:

3(x + 2y) + 4(2x - y)

Multiply 3, by x & by 2y:

3(x + 2y) ===> 3x + 6y

Then, multiply 4, by 2x & by -y:

4(2x - y) ===> 8x - 4y

Finally, you add/subtract the two results from the parenthesis:

3x + 6y + 8x - 4y ===> 11x + 2y

Your final expanded result will be: 11x + 2y.

The price of each book must be either $38.53 or $10.8 to generate a total sales revenue of $1,24,875.

If the prices of a book is $16 then 10000 copies will be sold.

For every dollar that increase in price, 300 books will not be sold.

So if the price of a book increases $x then the total price of sold books is given by,

y = (16 + x)*(10000-300x)

Now total sales revenue of the books is $124875, that is, y = 124875.

So, (16+x)*(10000-300x) = 124875

160000 + 10000x - 4800x - 300x² = 124875

35125 + 5200x - 300x² = 0

25 (1405 + 208x - 12x²) = 0

12x² - 208x - 1405 = 0

Solving the above quadratic equation we get,

x = 22.53 or x = -5.20 (Rounding to two decimal places)

So the amount will be either (16+22.53) = $38.53 or (16-5.20) = $ 10.8.

Hence the price must be either $38.53 or $10.8.

The model have 4 degrees of freedom if a regression model has a sample of 30 observations using a dependent variable, 3 independent variables, and a constant.

In a linear regression model, the degrees of freedom for the model are calculated as the number of independent variables plus one (for the constant or intercept term). Therefore, in this case, since the model has 3 independent variables and a constant, the degrees of freedom for the model would be 3 + 1 = 4.

The degrees of freedom for the model represent the number of parameters estimated from the data to build the model. These parameters are the coefficients or weights of the independent variables and the constant term.

The degrees of freedom for the model are used to calculate the F-statistic, which is a measure of the overall significance of the regression model. The F-statistic is calculated as the ratio of the explained variance to the unexplained variance of the model, and it is compared to the F-distribution with degrees of freedom (k, n-k-1), where k is the number of independent variables and n is the sample size.

The probability that they run or bike for exercise is 0.91

The probability that a randomly selected executive runs or bikes for exercise can be calculated by adding the probability of running and biking for exercise, subtracting the probability of running and biking for exercise simultaneously (which would be double counted).

This can be expressed mathematically as:

A recent poll of 300 executives revealed how they exercise.

95 reported running, 127 reported biking and 49 reported that they both bike and run for exercise.

If one of these executives is randomly selected, the probability that they run or bike for exercise is 0.91.

This can be calculated by adding the probability of running and biking for exercise, subtracting the probability of running and biking for exercise simultaneously (which would be double counted).

This shows that the majority of executives prefer to exercise by running or biking.

P(Run or Bike for exercise) = P(Run) + P(Bike) - P(Run and Bike)

Plugging in our given values, we get:

P(Run or Bike for exercise) = P(Run) + P(Bike) - P(Run and Bike)

P(Run or Bike for exercise) = 95/300 + 127/300 - 49/300

P(Run or Bike for exercise) = 0.91

Answer:

x = 6 , y = 1.5

Step-by-step explanation:

4x = 3 × 8 = 24 ( divide both sides by 4 )

x = 6

2

[tex]\frac{5}{y}[/tex] = [tex]\frac{10}{3}[/tex] ( cross- multiply )

10y = 5 × 3 = 15 ( divide both sides by 10 )

y = 1.5

The distance from point A to point B is approximately 926.4 feet.

An angle is a measure of the amount of rotation between two lines, rays, or line segments that share a common endpoint, called the vertex. It is typically measured in degrees or radians.

Let's call the distance between point A and the lighthouse "x" and the distance between point B and the lighthouse "y". We want to find the value of "y".

From point A, the crew measures the angle of elevation to the lighthouse to be 6. This means that the angle formed between the horizontal line passing through point A and the line connecting point A to the top of the lighthouse is 6. We can draw a right triangle ABC where point A is the bottom left corner, point B is the bottom right corner, and point C is the top of the lighthouse. The line segment AC represents the height of the lighthouse (111 feet) and the line segment AB represents the distance between point A and the lighthouse (x).

Using trigonometry, we know that:

tan(6) = AC/AB

tan(6) = 111/x

x = 111/tan(6)

Now, from point B, the crew measures the angle of elevation to the lighthouse to be 13. This means that the angle formed between the horizontal line passing through point B and the line connecting point B to the top of the lighthouse is 13. We can draw a right triangle BCD where point B is the bottom left corner, point C is the top of the lighthouse (the same point as in the previous triangle), and point D is the bottom right corner. The line segment CD represents the height of the lighthouse (111 feet) and the line segment BD represents the distance between point B and the lighthouse (y).

Using trigonometry, we know that:

tan(13) = CD/BD

tan(13) = 111/y

y = 111/tan(13)

Therefore, the distance between point A and point B is:

y - x = 111/tan(13) - 111/tan(6)

Using a calculator, we get:

y - x ≈ 926.4 feet

Rounding to the nearest tenth of a foot, the distance from point A to point B is approximately 926.4 feet.

Solving the equations we get the average cost of movie tickets for Japan is $17.42 and Switzerland is $13.07.

What is equation?

An equation is a mathematical statement which is made by two expressions connected by an equal sign. For example, 3x – 8 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 8.

Let, the cost for 1 movie ticket in Japan = $x

the cost for 1 movie ticket in Switzerland = $y

It would cost $78.40 to buy three tickets in Japan plus two tickets in Switzerland.

So the first equation will be,

3x+2y= 78.40 ------------(1)

Three tickets in Switzerland plus two tickets in Japan would cost $74.05

From this the 2nd equation will be,

2x+3y= 74.05 --------------(2)

Multiplying equation (1) by 2 and multiplying equation (2) by 3 we get,

6x+4y= 156.8 --------------(3)

6x+9y= 222.15 ------------(4)

equation (4)- (3) gives,

5y= 65.35

y= 13.07

putting this value in equation (1) we get,

x= (78.40- 2× 13.07)/ 3

Step-by-step explanation:

f(x) = 12 × 4^x = 3×4 × 4^x = 3 × 4^(x + 1)

on day 0 (x = 0) the new participants are 3×4 = 12, as each of the 3 founders is sending the message out to 4 friends. so, 12 contacted friends as new participants.

on day 1 (x = 1), the new participants are 3×4×4 = 48, as each of the 12 new participants of day 0 are sending out 4 new messages.

on day 2 (x = 2), the new participants are 3×4×4×4 = 192, as each of the 48 new participants of day 1 are sending out 4 new messages.

and so on.

every new day the number of new participants of the previous day sends out 4 new messages, so, the number of the new participants of the new day is 4 times the number of new participants of the previous day.

so, the result of the previous day is multiplied by 4. and that is multiplied by 4. and that again. and so on.

but the starting value is 12. therefore, we need the 3×4 at the beginning, and we keep it, of course, as the foundation for all the future multiplications by 4.

On that particular day, approximately 272.32 BTUs of heat were transferred through the wall.

To calculate the amount of heat transferred through the walls on a particular day, we can use the formula:

Q = U × A × deltaT

where Q is the heat transferred (in BTUs), U is the overall heat transfer coefficient (in BTU/hr·ft^2·°F), A is the area of the wall (in ft^2), and deltaT is the temperature difference between the inside and outside of the wall (in °F).

First, let's calculate the area of the wall. The room has four walls, but we are only interested in the heat transferred through the wall with an R-value of 15. We can calculate the area of this wall as follows:

Area = Length × Height = 13 ft × 9 ft = 117 ft^2

Next, we need to calculate the overall heat transfer coefficient, U. The U-value is the reciprocal of the R-value, so:

U = 1 / R = 1 / 15 = 0.0667 BTU/hr·ft^2·°F

Now we need to calculate the temperature difference between the inside and outside of the wall. We are given that the outside temperature is 36 °F, but we don't know the inside temperature. Let's assume that the inside temperature is 70 °F, which is a typical room temperature. Then the temperature difference is:

deltaT = 70 °F - 36 °F = 34 °F

Finally, we can plug these values into the formula:

Q = U × A × deltaT

Q = 0.0667 BTU/hr·ft^2·°F × 117 ft^2 × 34 °F

Q ≈ 272.32 BTUs

Therefore, on that particular day, approximately 272.32 BTUs of heat were transferred through the wall.

The given set of side lengths 11, 24, and 26 does not form a right triangle.

To determine whether the set of side lengths form a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we have side lengths 11, 24, and 26. Let's check whether they satisfy the Pythagorean theorem.

Using the theorem, we have:

26^2 = 11^2 + 24^2

Simplifying the right-hand side, we get:

676 = 121 + 576

Therefore, the equation is false, and the set of side lengths satisfies the Pythagorean theorem.

To calculate the loan factor, we first need to calculate the monthly interest rate and the total number of monthly payments.

Monthly interest rate = Annual interest rate / 12

= 10.75% / 12

= 0.8958%

Monthly payments = Number of years * 12

Now, we can use loan factor formula, which is:

Loan factor = [monthly interest rate * (1 + monthly interest rate)^n] / [(1 + monthly interest rate)^n - 1]

Substituting the values, we get:

Loan factor = [0.008958 * (1 + 0.008958)^300] / [(1 + 0.008958)^300 - 1]

Let me briefly explain the key terms and reasoning:
Dependent variable:

This is the outcome variable that you are measuring in an experiment or study.

It depends on the independent variable(s), which are the factors you manipulate or observe to determine their effect on the dependent variable.
Continuous variable:

A continuous variable is a numerical variable that can take on an infinite number of values within a given range. Examples include weight, height, and temperature.
ANOVA:

ANOVA is a statistical method used to compare the means of two or more groups to determine if there are significant differences between them.

It evaluates the effect of one or more independent variables on a continuous dependent variable.
To conduct an ANOVA, the dependent variable must be continuous because the test relies on calculating the variance within and between groups.

The variance is a measure of dispersion or spread of the continuous data.

If the dependent variable were not continuous, it would be difficult to quantify the differences between group means, making it impossible to determine if the independent variable(s) had a significant effect.
