A Cone With A Height Of 50 Meters Has A Volume Of 5400pie What Is The Radius Of The Cone

Answers

Answer 1

Given:

Height of a cone = 50 m

Volume of cone = 5400π

To find:

The radius of the cone

Solution:

Volume of cone:

[tex]$V=\frac{1}{3}\pi r^2h[/tex]

[tex]$\frac{1}{3}\pi r^2h=5400\pi[/tex]

Cancel common factor π on both sides.

[tex]$\frac{1}{3} r^2h=5400[/tex]

Substitute h = 50.

[tex]$\frac{1}{3}\times r^2\times 50=5400[/tex]

Multiply by 3 on both sides.

[tex]$3 \times \frac{1}{3}\times r^2\times 50=5400\times 3[/tex]

[tex]$ r^2\times 50=16200[/tex]

Divide by 50 on both sides, we get

[tex]r^2=324[/tex]

Taking square root on both sides, we get

[tex]r=18[/tex]

The radius of the cone is 18 m.

The binomials that are a difference of squares are [tex]9x^2 - 16[/tex] and [tex]m^6 - 25[/tex], as both can be factored into the form (a + b)(a - b).

Explanation:

The question asks which binomials are a difference of squares. A difference of squares is a binomial in the form [tex]a^2 - b^2[/tex], which can be factored into (a + b)(a - b). Analyzing the given options:

[tex]y^4 + 9[/tex]: This is not a difference, it's a sum.

[tex]9x^2 - 16[/tex]: This is a difference of squares because [tex]9x^2 = (3x)^2[/tex] and 16 = [tex]4^2[/tex].

[tex]m^6 - 25[/tex]: This is a difference of squares because [tex]m^6 = (m3)^2[/tex] and [tex]25 = 5^2[/tex].

[tex]p^7 - 1[/tex]: This is not a difference of perfect squares; [tex]p^7[/tex] is not a perfect square.

Therefore, the binomials that are a difference of squares are [tex]9x^2 - 16[/tex] and [tex]m^6 - 25[/tex].

Answer:

y = 6/5x -5

Step-by-step explanation:

Using the slope formula,

you can find the slope

or just divide the amount of units up by

the amount of units right.

Then find the y intercept which is (0,5)

Answer:

y = [tex]\frac{6}{5}[/tex]x -5

Step-by-step explanation:

Whenever we have a line such as this one, (A linear or straight line) we can write an equation with the form y = mx + b

m is the slope

b is the y-intercept

To calculate slope or "m" we see how many times the point goes up, and how many times it goes to the right, and then put it in a fraction.

(Units it goes up) / (Units it goes to the right)

The y-intercept is what number the line intersects on the y-axis.

On this line it intersects at the -5 point.

So the equation when you put in the values is y = [tex]\frac{6}{5}[/tex]x -5

Answers

When we graph the function, it has a vertex of (3, 16).

The maximum of the graph is the highest "x" value on the graph which is 3.

Since the maximum is 3, it will take 3 seconds for the ball to reach its maximum height.

A graph will be shown below showing the function and vertex.

Best of Luck!

Answer:

3 seconds

Step-by-step explanation:

We need to find where the maximum i.  The maximum or minimum  is at the vertex.  We know where the zero are because the equation is written in the zero form

We know the vertex is 1/2 way between the zeros

h(x)=-(x+1)(x-7)

Using the zero product property

x+1 = 0  x-7 =0

The zeros are at -1 and 7

Adding the two together and dividing by 2

(-1+7)/2 = 6/2 =3

The maximum is at 3.  We know it is the maximum because the equation is pointing down because of the negative out front.

Final answer:

The solution to the system of linear equations x + y = 8 and 3x + 2y = 21 is found using the elimination method, resulting in x = 5 and y = 3.

Explanation:

To solve the given system of equations:
x + y = 8
3x + 2y = 21
we can use either substitution or elimination method. For this instance, let's use the elimination method.

Multiply the first equation by 2 to match the coefficient of y in the second equation:

2(x + y) = 2(8)
2x + 2y = 16

Now, we have:

2x + 2y = 16

3x + 2y = 21

Subtract the second equation from the first:

(2x + 2y) - (3x + 2y) = 16 - 21
-x = -5
x = 5

Now that we have x, we can plug it back into the first equation:

x + y = 8
5 + y = 8
y = 8 - 5
y = 3

The solution to the system of equations is x = 5 and y = 3.

April has a sheet of paper that is 2 feet long. She cuts the length of paper into halves and then cuts the length of each of these 1/2 pieces into thirds. How many pieces does she have? How many inches long is each piece?

Answers

April has a total of 6 pieces of paper, with each piece being 4 inches long after she cuts the 2-foot paper into halves and then into thirds.

To solve this problem, we need to perform two cuts. The initial length of the paper is 2 feet. When April cuts the length of paper into halves, she now has two pieces each of 1 foot in length. Then, she cuts each of these halves into thirds. To find out how many pieces she has in total, we multiply 2 halves by 3, resulting in 6 pieces of paper in total.

To determine the length of each piece in inches, we start with the original measurement in feet. Since 1 foot is equivalent to 12 inches, we convert the 1-foot pieces to inches by multiplying by 12. Then, we divide by 3 to represent the three cuts that April makes:

1 foot = 12 inches

Each cut piece = 12 inches / 3

Each piece is 4 inches long.

Points and their residual values are shown in the table. A 3-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled y with entries 2, 3.5, 5, 6.1, 8. The third column is labeled residual value with entries negative 0.4, 0.7, negative 0.2, negative 0.6. Which residual value is the farthest from the line of best fit?

Answers

Answer:

The residual value is the farthest from the line of best fit is 0.7.

Step-by-step explanation:

A simple linear regression line is given by,

[tex]\hat y = \alpha + \beta X + \hat e[/tex]

Here,

α = constant,

β = slope

e = residual.

The difference amid the observed value of the dependent variable (Y) and the predicted value (y) is known as the residual (e).  

The formula to compute the residual is,

[tex]\hat e=y-\hat y[/tex]

The information provided is:

x           y           e

1          2.0       -0.4

2         3.5         0.7

3         5.0        -0.2

4         6.1         -0.6

5         8.0         0.0

The residuals are the difference between the actual value and the predicted value.

They can also be defined as the distance between the line of best fit and the actual value of the dependent variable.

The data point that is the farthest from the line of best fit is, y = 3.5.

The residual value of y = 3.5 is 0.7.

In terms of units distance, this value of y is the farthest from the line of bet fit.

Thus, the residual value is the farthest from the line of best fit is 0.7.

To analyze a function's graph, identify the domain and range, find the intercepts, assess whether the function is increasing or decreasing, and locate the extrema points.

Explanation:

Without the graph, I can't provide a specific analysis. However, I can guide you on how to analyze a function graph. A function graph can give specific details such as the function's domain and range, its intercepts, whether it's increasing or decreasing, and any extrema points (maxima or minima).

To find the domain, you need to identify which 'x' values are included on the graph. The range refers to the 'y' values covered by the graph. The intercepts are points where the graph crosses the 'x' axis (x-intercepts) and 'y' axis (y-intercepts).

By checking if the function is rising (increasing) or falling (decreasing), and spotting the highest and lowest points (maxima and minima), you can explore the behavior of the function.

Answers

Final answer:

Number sense enhances a student's understanding of multiplication and helps them choose the most efficient written method. For example, 0.5 can be easily multiplied mentally, and this knowledge can be applied to written methods for multiplying decimals.

Explanation:

In mathematics, number sense refers to a person's understanding of numbers and their relationships. It involves the ability to perform mental calculations and estimate the magnitude of numbers. On the other hand, written methods such as partial products or area models are specific algorithms or procedures used to solve mathematical problems, including multiplying decimal numbers.

The relationship between number sense and written methods for multiplying decimal numbers is that number sense enhances a student's understanding of the concept of multiplication and helps them make connections between different strategies or methods. By developing number sense, students can choose the most efficient written method based on their understanding of the numbers involved and their relationships.

For example, if a student has a strong number sense, they may recognize the relationship between a decimal that can be easily multiplied mentally, such as 0.5, and other decimal numbers. They can then use this knowledge to apply a written method like area models or partial products to solve problems that involve multiplying decimals.

Step-by-step explanation:

W=15 L=5 H=4

A= 2((15*5)+(4*5)+(4*15))

A= 310

The surface area of a rectangular prism with dimensions 15in by 5in by 4in is calculated using the formula 2lw + 2lh + 2wh, resulting in a surface area of 310 square inches.

The question asks: What is the surface area of the rectangular prism with dimensions 15in, 5in, 4in?

To find the surface area of a rectangular prism, we use the formula: Surface Area = 2lw + 2lh + 2wh, where l represents length, w represents width, and h represents height.

Using the given dimensions:

Length (l) = 15in

Width (w) = 5in

Height (h) = 4in

We calculate the surface area as follows:

Surface Area = 2(15)(5) + 2(15)(4) + 2(5)(4)

Surface Area = 150 + 120 + 40

Surface Area = 310 square inches

Therefore, the surface area of the rectangular prism is 310 square inches.
