Step-by-step explanation:

The diameter of the hemisphere with a volume of 557 m³ is approximately 12.8 m, to the nearest tenth of a meter.

The volume of a hemisphere can be calculated using the formula V = (2/3)πr³, where V is the volume and r is the radius. Given that the volume of the hemisphere is 557 m³, we can find the radius by solving for r:

557 = (2/3)πr³

To find the radius, first, we need to isolate r³ by multiplying both sides by 3/(2π):

r³ = (3 * 557) / (2 * π)

r³ ≈ 265.18

Now, take the cube root of both sides to find the radius:

r ≈ 6.4 m

To find the diameter, simply multiply the radius by 2:

d ≈ 2 * 6.4
d ≈ 12.8 m

Answer:

120in

Step-by-step explanation:

Okay, this is going to be a long one so hang onto your hats let's go

So, we first have to find the length that each of the frogs jumped so:

We're going to start with froggy #1, the 2-inch frog:

2 x 20 = 40

So froggy #1 can jump up to 40 inches so we're going to assume that each time our froggies jump, they jump to their full extent:

40 x 3 = 120

So froggy #1 jumped 120 inches

Now, we do the same with froggy #2, the 4-inch frog:

4 x 20 = 80

80 x 3 = 240

So froggy #2 jumped 240 inches

Now, we have to figure out how far ahead froggy #2 is from froggy #1:

240 - 120 = 120

So, the two froggies will end up 120 inches apart

hope this helps:)

The characteristic equation is -λ(λ-4)(λ+3) = 0, and the corresponding eigenvalues and eigenvectors are:

λ1 = 0, v1 = [1, 3]

λ2 = 4, v2 = [5, -4, 3]

λ3 = -3, v3 = [1, 1, 0]

What is an identity matrix?

An identity matrix is a square matrix with ones (1) along the main diagonal (from the upper left to the lower right) and zeros (0) everywhere else. It is denoted by I, and its size is indicated by a subscript. For example, I2 represents a 2x2 identity matrix:

To find the characteristic equation and eigenvalues of the given matrix, we need to compute the determinant of the matrix A - λI, where λ is the eigenvalue and I is the identity matrix.

A = 0 -3 5

-4 4 -10

0 0 4

A - λI = -λ -3 5

-4 4-λ -10

0 0 4-λ

The determinant of A - λI is given by:

det(A - λI) = (-λ) [(4-λ)(-3) - (-10)(-4)] - (-4)[(-4)(-3) - (-10)(-λ)] + (0)[(-4)(5) - (4-λ)(-3)]

= -λ(λ-4)(λ+3)

Therefore, the characteristic equation is:

-λ(λ-4)(λ+3) = 0

The eigenvalues are the roots of this equation, which are:

λ = 0, 4, -3

To find the eigenvectors corresponding to each eigenvalue, we solve the system of linear equations (A - λI)x = 0.

For λ = 0, we have:

(A - λI)x = -3 5

-4 4

0 0

which leads to the equation -3x + 5y = 0 and -4x + 4y = 0. Solving this system of equations, we get:

x = y/3

So, the eigenvector corresponding to λ = 0 is:

v1 = [1, 3]

For λ = 4, we have:

(A - λI)x = -4 -3 5

-4 0 -10

0 0 0

which leads to the equation -4x - 3y + 5z = 0 and -4x - 10z = 0. Solving this system of equations, we get:

x = (5/3)z

y = (-4/3)z

So, the eigenvector corresponding to λ = 4 is:

v2 = [5, -4, 3]

For λ = -3, we have:

(A - λI)x = 3 -3 5

-4 7 -10

0 0 7

which leads to the equation 3x - 3y + 5z = 0, -4x + 7y - 10z = 0 and 7z = 0. Solving this system of equations, we get:

x = y

z = 0

So, the eigenvector corresponding to λ = -3 is:

v3 = [1, 1, 0]

Therefore, the characteristic equation is -λ(λ-4)(λ+3) = 0, and the corresponding eigenvalues and eigenvectors are:

λ1 = 0, v1 = [1, 3]

λ2 = 4, v2 = [5, -4, 3]

λ3 = -3, v3 = [1, 1, 0]

~

First, distribute 2 to all terms within the parenthesis:

2(8 - 12x) = (2 * 8) - (2 * 12x) = 16 - 24x

Next, combine like terms. Like terms are terms with the same variables and the same amount of variables:

16 - 24x + 8x = -25x + 52

16 - 16x = -25x + 52

Isolate the variable, x. Add 25x and subtract 16 from both sides:

16 (-16) - 16x (+25x) = -25x (+25x) + 52 (-16)

-16x + 25x = 52 - 16

Combine like terms:

25x - 16x = 52 - 16

9x = 36

Isolate the variable, x. Divide 9 from both sides:

(9x)/9 = (36)/9

x = 36/9

x = 4

Answer:

It is logical to get three cases

Step-by-step explanation:

The length and the width of the 500 sheet paper are 216 and 279 mm, respectively, which means that the height for the 500 sheet paper is 45 mm, and for the package, it is 270 mm. This means that 6 (270/45)  500 sheet papers can fit, which is 3000 individual papers. She needs 7000, and since she can only get 6000 from each full case (and can only get it from a full case) she needs to get 3 cases; because if she only gets 2, she can't get any extra, but if she gets three, she gets extra but heeds to her limit. So it is logical to get three cases.

Answer:

  3 cases

Step-by-step explanation:

You want to know the number of cases of printer paper that should be ordered to fill a need for 7000 sheets when there are 500 sheets per 45 mm package in a 270 mm case.

Each package is 45 mm thick, and the case is 270 mm thick. The case will hold ...

  (270 mm/case) / (45 mm/package) = 270/45 packages/case

  = 6 packages/case

The number of packages needed is ...

  (7000 sheets) / (500 shees/package) = 7000/500 packages

  = 14 packages

Then the number of cases needed is ...

  (14 packages) / (6 packages/case) = 14/6 cases = 2 1/3 cases

If only whole cases can be ordered, 3 cases should be ordered to fill the need.

__

Additional comment

We notice that the 216 mm×279 mm footprint of a package is the same as that for a case, so we only need to be concerned with the thickness of the package and the case.

If the data are graphed symmetrically, the distribution demonstrates 0% skewness regardless of how long or fat the tails are. When the median of a data set is utilized, 50% of the data points in the collection have values lower than or equal to the median, and 50% of them have values greater than or equal to the median. The middle score in the set is known as the median. The first step in calculating the median is to order the data points from smallest to greatest. The median in an odd-numbered set will be the value that falls exactly in the middle of the list. You must determine the average of the two middle numbers in a set of even numbers. The average is determined by summing up each value individually and dividing that sum by the total number of observations.

Answer: 108 cups of cranberry juice. Brainliest?

Step-by-step explanation:

mixed juice. How many cups of cranberry juice did Jetia use?

Let's start by assuming that Jetia used x cups of cranberry juice to make the mixed juice. Then, since the ratio of cranberry juice to apple juice is 5:8, she must have used (5/8)x cups of apple juice.

We know that the total amount of mixed juice is 177 cups, so we can set up an equation based on the total amount of juice:

x + (5/8)x = 177

Simplifying this equation, we get:

(13/8)x = 177

Multiplying both sides by 8/13, we get:

x = 108

Therefore, Jetia used 108 cups of cranberry juice to make the mixed juice.

The area of a rhombus can be found by multiplying the length of one of its sides by the height of a perpendicular line from the center to a side.

The height of the rhombus is the distance from the center of the rhombus to one of its sides, perpendicular to that side.

The formula for the area of a rhombus can be written as A = s*h, where A is the area, s is the length of one of the sides of the rhombus, and h is the height of the rhombus.

It's important to note that this method of finding the area of a rhombus without diagonals can only be used when the rhombus is a regular polygon, a polygon with all sides and angles congruent. When the rhombus is not a regular polygon, then you can find the area by using the diagonals.

Additionally, it's important to mention that a rhombus can be defined as a parallelogram with all sides congruent or a square with its angles not 90 degrees.

The finite difference scheme that can be used to estimate the first derivative is option 3: dx/dt = (x[i+1] – x[i-1]) / (2T).

The finite difference scheme is a numerical method used to approximate derivatives. In this case, we want to estimate the first derivative dx/dt. Option 3, dx/dt = (x[i+1] – x[i-1]) / (2T), is the correct scheme for approximating the first derivative.

In this scheme, x[i+1] and x[i-1] represent the values of the function at neighboring points in the x direction, and T represents the time step.

By subtracting the value at x[i-1] from the value at x[i+1] and dividing it by 2T, we obtain an approximation of the derivative dx/dt at the point x[i].
