Answer:

it is probably 70° of the triangle

The value of x in the triangle is 75°

Triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC.

The sum of angles in a triangle is 180°. Also the sim of angles on a straight line is also 189°

One of the triangle theorem is that the exterior angle of a triangle is equal to the sum of the opposite angles.

x + 2 = -2y + 2

This is the symmetric equation of the line that passes through the point P and is parallel to the vector .

What is symmetric equation?

A line that passes through the point P and is parallel to the vector v can be represented by the parametric equation:

x = -2 + 0t

y = 1 + 2t

z = 0 - 3t

where t is a scalar parameter. To find the symmetric equation of this line, we need to convert the parametric equation to a normal form. We'll start by finding a point on the line other than P, then use those two points to find the direction vector of the line. Let's use t = 1, then the line passes through the point Q(-2 + 01, 1 + 21, 0 - 3*1) = (-2, 3, -3). The direction vector of the line is found by subtracting the position vectors of P and Q:

d = Q - P = (-2 - (-2), 3 - 1, -3 - 0) = (0, 2, -3) = v

So, the direction vector and the vector v are equal, which means the line is parallel to v. Now we have two points on the line, P and Q, which we can use to find the symmetric equation of the line:

(x + 2)/0 = (y - 1)/2 = (z + 3)/(-3) = t

x + 2 = -2t

y - 1 = 2t

z + 3 = 3t

Rearranging the above equations, we get:

x = -2 - 2t

y = 2t + 1

z = 3t - 3

Since t is a scalar parameter, it can be eliminated from the equations to obtain the symmetric equation of the line:

x + 2 = -2y + 2

y - 1 = 2z + 2

= 3/10 or 0.3

The slope of this line is m = 1.

An equation of this line is y = x.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Based on the information provided, we can logically deduce the following data points on the line:

Substituting the given data points into the slope formula, we have the following;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1 - 0)/(1 - 0)

Slope (m) = 1/1

Slope (m) = 1

At data point (1, 1), an equation of this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

There is no value of n such that both 3ⁿ⁻¹ and 5ⁿ⁻¹ are divisible by 7.

For d=7, we can see that:

3² - 1 = 8 is divisible by 7, but 5² - 1 = 24 is not divisible by 7.

For larger values of d such as 11, 13, 77, and 1001, we can use a similar approach to see if there are any values of n such that both 3ⁿ⁻¹ and 5ⁿ⁻¹ are divisible by d. However, finding an exact value of n for larger values of d may be difficult without using more advanced mathematical methods.

In general, the number of values of n such that both 3ⁿ⁻¹ and 5ⁿ⁻¹ are divisible by a given integer d will depend on the properties of the numbers 3, 5, and d. For example, if d is a prime number that is not a divisor of either 3 or 5, it is likely that there are only a few values of n such that both 3ⁿ⁻¹ and 5ⁿ⁻¹ are divisible by d.

However, if d is a composite number or a divisor of either 3 or 5, there may be more values of n such that both 3ⁿ⁻¹ and 5ⁿ⁻¹ are divisible by d. Whether there are finitely or infinitely many such n will depend on the specific values of 3, 5, and d.

Decreasing the sample size, while holding the confidence level the same, will make the width of your confidence interval bigger. So option a. is correct.

The width of a confidence interval is a measure of the degree of uncertainty in the estimate of the population parameter. It is determined by the sample size, the confidence level, and the standard deviation of the population.

When the sample size decreases, the standard deviation of the sample estimate increases, making the width of the confidence interval larger. This reflects the increased uncertainty in the estimate of the population parameter.

Therefore, decreasing the sample size while holding the confidence level the same will result in a wider confidence interval.

The function sin(x-y)/cosec(x+y)=sin²x-sin²y

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We have to prove that sin(x-y)/cosec(x+y)=sin²x-sin²y

Using the identity cosecx=1/sinx

We get sin(x-y)/cosec(x+y)=sin(x-y)sin(x+y)

We know sin(x+y)=sinxcosy+cosxsiny

sin(x-y)=sinxcosy-cosxsiny

Now sin(x-y)sin(x+y)=(sinxcosy-cosxsiny)(sinxcosy+cosxsiny)

=sin²xcos²y-cos²xsin²y

=sin²x(1-sin²y)-(1-sin²x)sin²y

The total surface area painted black is 12.6 sq. feet.

The surface area of a cone with height h and circumference of the base c can be calculated using the formula:

A = πr^2 + πrs,

where,

r = the radius of the base

s = the slant height.

We can find the radius of the base by dividing the circumference by 2π:

r = c / (2π)

  = 8π / (2π)

r = 4.

The slant height can be found using the Pythagorean theorem:

s = √(r² + h²)

  = √(4² + 12²)

  = √(16 + 144)

  = √(160)

s = 12.7279

So the surface area of each cone is:

A = πr² + πrs

= π * 4² + π * 4 * 12.7279

= 3.14 * 4² + 3.14 * 12.7279

= 50.265...

The base and 50% of the lateral surface are painted red, which is a total of 50% + 100% / 2 = 75% of the surface area.

So the total surface area painted black is:

(100% - 75%) * A

= 25% * A

= 25% * 50.265

Let's call the time it takes the fair maiden to sew the border of the tapestry "t". So, her sister can sew the border in t/2 hours.

Working together, they can sew the border in t + t/2 = 1.5t hours.

Since we know the fair maiden can sew the border in 6 hours, we can substitute this into the equation to find t:

6 + 6/2 = 1.5t

Simplifying the right side of the equation:

6 + 3 = 1.5t

9 = 1.5t

Dividing both sides of the equation by 1.5:

t = 6

So the fair maiden can sew the border in 6 hours and her sister can sew the border in 6/2 = 3 hours.

Working together, it would take them 6 + 3 = 9 hours to sew the border of the tapestry.

The equation does not hold true, indicating that point C does not lie on line AB.

The equation of line AB can be written in slope intercept form as y = mx + b. The slope of line AB can be found using the equation m = (y2-y1)/(x2-x1). Substituting the coordinates of points A and B into the equation, we get m = (2-4)/(-5-2) = -2/7. The slope-intercept form of this equation is y = -2/7x + b. We can find the value of b by substituting the coordinates of point A into the equation. We get b = 4 + 2/7 = 19/7.

Therefore, the equation of AB in slope-intercept form is y = -2/7x + 19/7. To check whether point C lies on line AB, we must substitute the coordinates of point C into the equation. We get y = -2/7(-1)+19/7 = -2/7 + 19/7 = 17/7. Since the y-coordinate of point C is 8, the equation does not hold true, indicating that point C does not lie on line AB.

Writing the function P = 35(1.3)^t in the form P(0)e^{kt}, the value of k = log(1.3) and P(0) = 35.

The function is P = 35(1.3)^t

At t = 0, P = 35, so P(0) = 35

P = 35e^{kt} .................Equation 1

P = 35(1.3)^t .................Equation 2

Step-by-step explanation:

No, you're incorrect. The tournament lasted from 12:15pm to 4:00pm, which is a duration of 3 hours and 45 minutes. So, the tournament lasted less than 4 hours.

To calculate the duration, you subtract the start time from the end time:

4:00pm - 12:15pm = 3 hours and 45 minutes

Therefore, the tournament lasted for 3 hours and 45 minutes, which is less than 4 hours.

Here's a step-by-step breakdown of the calculation:

Start by calculating the number of whole hours between the start and end time.

4:00pm - 12:15pm = 3 hours

Next, calculate the number of remaining minutes.
