if the diameter of a cone is 19 yd and the height is 13 yd . What is the volume?

Answers

If the diameter of a cone is 19 yd and the height is 13 yd, the volume of this cone is equal to 1,228 cubic yard.

How to calculate the volume of a cone?

Mathematically, the volume of a cone can be calculated by using this formula:

V = 1/3 × πr²h

Where:

V represents the volume of a cone.h represents the height.r represents the radius.

Radius = diameter/2 = 19/2 = 9.5 cm.

Substituting the given parameters into the volume of a cone formula, we have the following;

V = 1/3 × πr²h

V = 1/3 × 3.14 × 9.5² × 13

Determine the Equation of circle A

Answers

Answer:

Step-by-step explanation:

When writing the equation for a circle on a plane, we use the format:

[tex](x-x_{1})^2+(y-y_{1})^2=r^2[/tex]

x1 and y1 is the point of the center of the circle, which in this case is (1,-2)

r represents the radius, which is the distance from the center to the edge of the circle, which is (4,-2) - (1,-2) = 3

Our equation is now:

[tex](x-1)^2+(y+2)^2=9[/tex]

the reason why its y+2 is because (y-(-2) = (y+2)

r is squared, which is why it's 9 instead of 3. Hope this helps!

The scale factor of two similar hexagons is 3:7.

The area of the smaller hexagon is 18 m2.

What is the volume of the larger hexagon?

Question 7 options:

5832 m2


36 m2


42 m2


324 m2


98 m2

Answers

Since the two hexagons are similar, their corresponding sides are in the same ratio as the scale factor.

Let x be the length of a side of the smaller hexagon, then the corresponding length of a side of the larger hexagon can be expressed as (3/7)x.

The area of a hexagon can be calculated using the formula: A = (3√3/2)s², where s is the length of a side.

Since the area of the smaller hexagon is 18 m², we can solve for x as follows:

18 = (3√3/2)x²

x² = 12/√3

x = 2√3

Now we can calculate the area of the larger hexagon:

Area of the larger hexagon = (3√3/2)(3/7x)² = (3√3/2)(3/7(2√3))² = 54/49 m²

Finally, we can calculate the volume of the larger hexagon, assuming it is a regular hexagonal prism:

Volume of the larger hexagon = Area of hexagon x Height

The height of the hexagonal prism is the same as the length of the side of the larger hexagon, which is (3/7)x:

Volume of the larger hexagon = (54/49) x (3/7)x = 54/343 x² ≈ 0.212 x²

Substituting the value of x, we get:

Volume of the larger hexagon ≈ 0.212 x (2√3)² = 1.272 m³

Therefore, the volume of the larger hexagon is approximately 1.272 m³.

Well, I'm not sure if it's correct but I got 42.

I got this by doing something along the lines of:

1) 18/x = 3/7

2) Cross multiply

3) 3x = 126

4) Divide both sides by 3

5) x = 42

The graph of polygon FGHI is shown. Graph the image of FGHI after a reflection across the line y=-1. Include the line of reflection. Then write the coordinates of the image.​

Answers

The coordinates of the reflected polygon F'G'H'I' are as follows:

F'(-2, -1), G'(5, -4), H'(8, -5), and I'(6, -2).

What is the reflection?

In mathematics, reflection is defined as the mirror image of a figure crossing a line (drawn or imagined), known as the line of reflection.

The vertices of the polygon FGHI are as follows:

F(2, -1)

G(5, 2)

H(8, 3)

I(6, 0)

To reflect the polygon FGHI across the line y = -1, we need to flip the points over the line.

Now we can reflect each of the points of the polygon across the line y = -1 to get the image:

F(2, -1) stays in the same place because it lies on the line of reflection.

G(5, 2) is reflected to G'(5, -4) by flipping it vertically across the line y = -1.

H(8, 3) is reflected to H'(8, -5), and

I(6, 0) is reflected to I'(6, -2).

He will accept the shipment if the claim is found true and reject if the percentage of defective items is more. To verity this claim, he draws a sample of 200 items and finds that 10 items are defective. Use 5% level of significance to investigate the claim.

Answers

At a 5% level of significance, the claims that a shipment of goods contains at most 2% defective items is accepted.

To investigate the claim that the shipment contains at most 2% defective items, we can use the 5% level of significance. The claim is that the population proportion of defective items is at most 2%, or p0 ≤ 0.02. The sample size is n = 200, and the sample proportion of defective items is pobs = 10/200 = 0.05.

The test statistic is then:

z = (pobs - p0) / √(p0(1-p0) / n)

= (0.05 - 0.02) / √(0.02(1-0.02)/200)

= 1.02.

With a 5% level of significance, we can look up the critical value for a one-tailed z-test and find that it is zα/2 = 1.645. Because 1.02 < 1.645, the test statistic is not greater than the critical value, and thus we fail to reject the null hypothesis that the population proportion of defective items is at most 2%.

In conclusion, with a 5% level of significance, the claim that the shipment contains at most 2% defective items is accepted.

vIf the slope of a line is 32, how much vertical change will be present for a horizontal change of 96ft?

Answers

A horizontal change of 96ft, there will be a vertical change of 3072ft.

The slope of a line is the ratio of the vertical change to the horizontal change between two points on the line. In other words, the slope is the rise over the run.

If the slope of a line is 32, that means that for every 1 unit of horizontal change, there is a 32 unit vertical change.

So, if the horizontal change is 96ft, we can use the slope formula to find the vertical change:

Vertical change = slope × horizontal change

Vertical change = 32 × 96

Vertical change = 3072

Therefore, for a horizontal change of 96ft, there will be a vertical change of 3072ft.

Find angle A on a triangle when A(5x-1) B is unknown and C(2x)?

  ∠A = 64°

Step-by-step explanation:

You have a triangle inscribed in a semicircle with acute angles marked A=(5x-1)° and C=(2x)°.

Right triangle

A triangle inscribed in a semicircle is a right triangle. (You know that because angle B is half the measure of 180° arc AC.) That means the two marked angles total 90°:

  (5x -1) +(2x) = 90

  7x = 91

  x = 13

Then angle A is ...

  A = (5·13 -1)° = (65 -1)° = 64°

The measure of angle A is 64°.

__

Check:

  C = (2x)° = (2·13)° = 26°

Then A+C = 64° +26° = 90°, as required.

Answers

The system of equations shown models the total costs for taking 10 classes at each.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Given that Toe Tappers charges a rate for each class plus a one-time registration fee.

Dance World, y = 15x

Toe Tappers, y = 25 + 12.5x

Where x = number of classes

Now Equate the total cost at both dance studios;

15x = 25 + 12.5x

Collect like terms;

15x - 12.5x = 25

2.5x = 25

If Emma needs to travel a distance of 15 miles or less, she should choose the red cab company because it has a lower cost. If she needs to travel more than 15 miles, she should choose the yellow cab company  

Determining the company that minimizes cost

From the question, we are to determine which company Emma should use when she wants to minimize cost.

Let's assume that Emma needs to travel a distance of d miles to get to the airport.

The cost C of taking the red cab company can be represented by the function:

Cred(d) = 3.50 + 1.25d

Similarly, the cost C of taking the yellow cab company can be represented by the function:

Cyellow(d) = 5.00 + 1.15d

To determine which company Emma should use to minimize cost, we need to find the value of d that makes the cost of each company equal. In other words, we need to solve the equation:

Cred(d) = Cyellow(d)

Substituting the expressions for Cred(d) and Cyellow(d), we get:

3.50 + 1.25d = 5.00 + 1.15d

Simplifying and solving for d, we get:

0.10d = 1.50

d = 15

Hence, if Emma needs to travel a distance of 15 miles or less, she should choose the red cab company because it has a lower cost. If she needs to travel more than 15 miles, she should choose the yellow cab company.

The first step in solving 5sin(x)−2cos(x)=3 is to rearrange the equation to isolate the sin(x) term. We can do this by adding 2cos(x) to both sides of the equation:

5sin(x) = 3 + 2cos(x)

Next, we can divide both sides of the equation by 5 to isolate the sin(x) term:

sin(x) = (3 + 2cos(x))/5

Now, we can use the Pythagorean identity sin^2(x) + cos^2(x) = 1 to substitute for cos(x) and solve for sin(x):

sin^2(x) = (3 + 2√(1 - sin^2(x)))/5

Multiplying both sides of the equation by 5 and rearranging gives us:

5sin^2(x) - 2√(1 - sin^2(x)) - 3 = 0

We can use the quadratic formula to solve for sin(x):

sin(x) = (-(-2) ± √((-2)^2 - 4(5)(-3)))/(2(5))

Simplifying gives us:

sin(x) = (2 ± √(28))/10

Using a calculator, we can find the first 2 positive solutions for x:

x = sin^-1((2 + √(28))/10) ≈ 0.72, 2.42

Therefore, the first 2 positive solutions for x are 0.72 and 2.42, accurate to at least 2 decimal places.

To find the maximum and minimum values of f(x)=5.7sin(x)−3.9cos(x), we can use the formula:

max = √(a^2 + b^2)

where a and b are the coefficients of the sin(x) and cos(x) terms, respectively. Substituting in the values for a and b gives us:

max = √((5.7)^2 + (-3.9)^2) ≈ 6.9159

The minimum value of the function is the negative of the maximum value:

min = -6.9159

Therefore, the maximum value of the function is 6.9159 and the minimum value is -6.9159, accurate to 4 decimal places. The answers should be provided as a list separated by commas, so the final answer is:

max = 6.9159, min = -6.9159

What is the constant of proportionality between

yy and

xx in the graph?

Answers

The response to the given question would be that The slope of the line is the constant of proportionality if the graph is a straight line through the origin.

what is proportionality?

Partnerships that have the same ratio across time are said to be proportional. For instance, how many trees there are in an orchard and how many apples there are in a harvest of apples are determined by the average number of apples per tree. Proportional in mathematics refers to a linear connection between two numbers or variables. As the first quantity doubles, so does the other. When one of the variables drops to 1/100th of its previous value, the other also decreases. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two quantities stays the same at all levels. As an example, consider the diameter and circumference of a circle.  

It is difficult to estimate the constant of proportionality between two variables, y and x, without first viewing the graph.

Nevertheless, the constant of proportionality may be calculated by dividing any y-value by its corresponding x-value if the two variables are directly proportional, which means that when x rises, y rises as well at a consistent pace.

If y = kx, where k is the proportionality constant, then mathematically, k = y/x at every point on the graph.

The slope of the line is the constant of proportionality if the graph is a straight line through the origin.
