From given volume, length of each section is 18 inches.

In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Let's call the length, width, and height of each section l, w, and h, respectively.

Since both sections are the same size, we can set up the following equation for their combined volume:

2(lwh) = 2640

Simplifying this equation, we get:

lwh = 1320

Now we need to find the length of each section, which is represented by the variable l. We can solve for l by dividing both sides of the equation by wh:

l = 1320/wh

We don't have enough information to determine w and h individually, but we do know that the two sections are identical, which means they have the same proportions. This means that w and h must be equal.

Let's call this common value x. Then we can rewrite the equation for l as:

[tex]l = 1320/x^2[/tex]

We can simplify this equation by multiplying both sides by [tex]x^2[/tex]:

[tex]lx^2 = 1320[/tex]

Now we can solve for x:

[tex]x^2 = 1320/l\\\\x = \sqrt{(1320/l)}[/tex]

Since w = h = x, the length of each section is:

[tex]l = 2x = 2 \sqrt{(1320/l)}[/tex]

We can simplify this expression by multiplying both sides by l:

[tex]l^2 = 4*1320/l \\l^3 = 5280\\l = 18[/tex]

Therefore, the length of each section is 18 inches.

Answer:

(-1, 2)

Step-by-step explanation:

1.) The way to use elimination is to add or subtract both of the equations together to eliminate a variable. If we add the two equations together, the -6x and 6x cancel out. Since we added the equations together, -12y and 10y would add up to -2y, and -18 and 14 would add up to -4

2.) Now, we have the equation -2y = -4. By dividing by -2 on both sides, we get y=2.

3.) Next, we need to substitute y back in to get the x value. If you use the first equation, we get -6x - 12 * 2 = -18.

4.) By simplifying, you get that -6x - 24 = -18. If you add 24 on both sides, you get -6x = 6, and by dividing by -6 on both sides, you get x = -1.

5.) Finally, you have to put the answer in form of a point. -1 would be the x-coordinate and 2 would be the y-coordinate. Therefore, the point is (-1, 2)

The book that weighs 3/4 pounds is greater than 1/2 pounds.

To compare the weights of the two books with 1/2 pound, we need to convert 1/2 pound into a fraction with a common denominator as the given weights. The common denominator of 8 and 4 is 8. So, we can convert 1/2 pound to 4/8 pound.

Now we can compare the weights of the two books with 4/8 pounds. The weight of the first book is 3/8 pounds, which is less than 4/8 pounds. The weight of the second book is 3/4 pounds, which is greater than 4/8 pounds.

Therefore, the book that weighs 3/4 pounds is greater than 1/2 pound.

Answer:

  7467 ft 1 in = 89605 inches on a side

Step-by-step explanation:

You want the dimensions of a square with an area of 2 square miles, to the nearest inch.

The area of a square is given by ...

  A = s² . . . . . . where s is the side length

For an area of 2 mi², the side length is ...

  2 mi² = s²

  √(2 mi²) = s = √2 mi

You want the distance to the nearest inch, so we need to convert this to inches.

  √2 mi = (√2 mi) × (5280 ft/mi) × (12 in/ft) ≈ 89604.57 in

Rounded to the nearest inch, this is

  89605 inches

In feet and inches, this is

  89605/12 ft = 7467 1/12 ft = 7467 ft 1 in.

Vertex of h(x) is (-2, 0), and the axis of symmetry is the line x = -2, vertex of g(x) is (3, 0), and the axis of symmetry is the line x = 3, vertex of j(x) is (3, 2), and the axis of symmetry is the line x = 3.

What is axis of symmetry?

In mathematics, the axis of symmetry is a line that divides a given shape into two symmetrical parts, such that each part is a mirror image of the other.

We can use the standard form of a quadratic function, which is given by:

[tex]F(x) = a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola and the axis of symmetry is the line x = h.

For [tex]h(x) = (x + 2)^2[/tex], we have:

h = -2 (since x + 2 = 0 when x = -2)

k = 0 (since the square of any real number is non-negative)

Therefore, the vertex of h(x) is (-2, 0), and the axis of symmetry is the line x = -2.

For [tex]g(x) = (x - 3)^2[/tex], we have:

h = 3

k = 0

Therefore, the vertex of g(x) is (3, 0), and the axis of symmetry is the line x = 3.

For [tex]j(x) = (x - 3)^2 + 2[/tex], we have:

h = 3

k = 2

Therefore, the vertex of j(x) is (3, 2), and the axis of symmetry is the line x = 3.

To find the y-intercept of each function, we can simply plug in x = 0:

For h(x):

[tex]h(0) = (0 + 2)^2 = 4[/tex]

Therefore, the y-intercept of h(x) is 4.

For g(x):

[tex]g(0) = (0 - 3)^2 = 9[/tex]

Therefore, the y-intercept of g(x) is 9.

For j(x):

[tex]j(0) = (0 - 3)^2 + 2 = 11[/tex]

Therefore, the y-intercept of j(x) is 11.

Answer:

To solve this problem, we can use the equations of motion for a vertically launched object. First, we need to find the initial velocity of the snowball when it is kicked off the ground. We know that its speed is 24 feet per second, but we also need to take into account the angle at which it is kicked. Let's assume that Max kicks the snowball at a 45-degree angle. Using trigonometry, we can find that the horizontal velocity of the snowball is also 24 feet per second, and the vertical velocity is 24 feet per second times the sine of 45 degrees, which is approximately 16.97 feet per second. Now we can use the following equation to find the time it takes for the snowball to hit the ground: h = vi*t + 0.5*a*t^2 where h is the maximum height, vi

Hence inverse of the function h is

h⁻¹ :x→  2/(x-1)  -1

An inverse function is a function that "undoes" the action of another function. In other words, if a function f(x) takes an input x and produces an output y, then its inverse function, denoted as f⁻¹(y) or sometimes as g(y), takes the output y and produces the input x such that f(x) = y.

 A function is a rule that associates each element of a set (called the domain) with a unique element of another set (called the range or codomain).

Given function

f(x)=1+1/x for x>0

g(x)=(x+1)/2  for x>0

Given: h=fg

h=f(g(x))

h=1+1/(x+1)/2

Now, taking the inverse of the function h,

h=1+1/(x+1)/2

h-1=1/(x+1)/2

1/(h-1)=(x+1)/2

2/(h-1)=x+1

x=2/(h-1) -1

The set of number sentences contains exactly one equation. That is the number sentence that has exactly one solution:

k is equal to 2, and the function g(x) is obtained by shifting the graph of f(x) two units to the left.

A function in mathematics is a relationship between a set of inputs (also known as the domain) and a set of outputs (also known as the range), where each input is connected to each output inexactly.

It can be compared to a machine that processes inputs and outputs in accordance with predetermined rules or algorithms.

In order to model real-world scenarios, carry out calculations, and examine mathematical relationships, functions are used.

They are frequently depicted through graphs or algebraic equations.

Since g(x) = f(x + k), we need to find the value of k that will shift the graph of f(x) to the graph of g(x). To do this, we can use the fact that g(x) = f(x + k) and the values in the table to determine the value of k.

When x = -1, g(x) = 5 = f(-1 + k). Since f has a point at (-1, 3), we know that f(-1) = 3.

Therefore, we have:

5 = f(-1 + k) = f(-1) + k = 3 + k

Solving for k, we get:

k = 5 - 3 = 2

Answer: B: (7, -4)

Step-by-step explanation:

To solve for x and y, we can use either substitution or elimination method. Here, we'll use the elimination method to solve for x and y:

2x - 4y = 36 (Equation 1)

4x + 3y = -5 (Equation 2)

To eliminate y, we can multiply Equation 1 by 3 and Equation 2 by 2, and then add the two resulting equations:

6(2x - 4y) = 6(36) (Multiplying Equation 1 by 3)

2(4x + 3y) = 2(-5) (Multiplying Equation 2 by 2)

Simplifying, we get:

12x - 24y = 216

8x + 6y = -10

Adding the two equations, we get:

20x = 206

Dividing both sides by 20, we get:

x = 10.3

Now, substituting x = 10.3 into Equation 1 or Equation 2, we can solve for y. Let's use Equation 1:

2x - 4y = 36

2(10.3) - 4y = 36

20.6 - 4y = 36

-4y = 15.4

y = -3.85

Therefore, the solution to the system of equations is (x,y) = (10.3,-3.85).

Rounded to the nearest integer, the solution is approximately (x,y) = (10,-4).

So, the answer is option B: (7, -4).

Use circumcenter to draw a circle through three non-collinear points.

a) Draw diameter, construct equilateral triangle with one vertex at center and other two on circle.

b) Draw diameter, construct regular hexagon with one vertex at center and other vertices on circle.

Step 1: To construct a circle through three points not on a line, we can use the circumcenter of a triangle. We first construct the perpendicular bisectors of any two sides of the triangle. The point where these two lines intersect is the circumcenter of the triangle. We can then draw a circle with this point as the center, which passes through all three vertices of the triangle.

older than those found in shallower layers of sediment. This is because sedimentary rock layers form over time, with the oldest layers at the bottom and the newest layers at the top. As sedimentary rocks form, they often trap the remains of plants and animals, which then become fossils. The deeper layers have been buried for a longer period of time, so they contain older fossils. This principle is known as the law of superposition and is an important tool for dating fossils and determining the relative ages of different rock layers.

As the degrees of freedom increase, the Student's t distribution becomes more like the standard normal (z) distribution. Correct option is C.

The Student's t distribution is a probability distribution that is used to estimate the mean of a population when the sample size is small or when the population standard deviation is unknown. It is similar to the standard normal distribution, but it has heavier tails and more spread out.

As the degrees of freedom increase, the t-distribution approaches the normal distribution because the shape of the t-distribution becomes more and more similar to the normal distribution.

This is due to the central limit theorem, which states that as the sample size increases, the distribution of the sample mean approaches the normal distribution.

When the degrees of freedom is large, the t-distribution becomes less variable, and the tails become less heavy, approaching the normal distribution. Therefore, the standard normal (z) distribution is the limiting distribution of the Student's t distribution as the degrees of freedom increase.
