The required volume of the right circular cone is 135.83409in³.

A right circular cone is one whose axis is the line between the vertex and the circular base's midway.

In other words, a right angle is formed when the center point of the circular base and the cone's peak are united.

So, the right circular cone volume formula:

V=1/3hπr²

Diameter = 8.8 in

Radius = 8.8/2 = 4.4 in
Now, calculate the volume as follows:

V = 1/3hπr²

V = 1/3(6.7)π(4.4)²

V = 135.83409 in³

Therefore, the required volume of the right circular cone is 135.83409in³.

Answer:It was not until the eighteenth century that mathematician Leonard Euler (1707-1783) discovered a relationship between the three classical triangle centers.

Step-by-step explanation:

Yes, you can solve for the y-intercept using the slope, one ordered pair, and the slope-intercept equation.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Here Rin says that you can solve for the y-intercept using the slope, one ordered pair, and the slope-intercept equation.

The statement is right because for the calculation of the y-intercept we need one point to pass through the line and the slope of the line.

To write an area, you need to know the shape and the measurements of the sides.

For example, if you have a square, you can calculate its area with the formula A = s², where A is the area and s is the length of a side.

If the side is 10 cm, then the area would be written as A = 10² = 100 cm².

1. Identify the shape of the area you are trying to calculate.

2. Calculate the measurements of the sides.

3. Use the appropriate formula to calculate the area. For example, for a square, use the formula A = s², where A is the area and s is the length of a side.

4. Plug in the measurements and calculate the area.

5. Write the area using the correct unit of measurement. For example, if the side was 10 cm, the area would be written as A = 10² = 100 cm².

Original shape will contract when scale factor is less than 1 , expand when scale factor is greater than 1 and it doesn't change when scale factor is 1

A scale factor is a number that can be used to change the size of any geometrical figure or shape in relation to its original size. It is the ratio of the sizes of the original and dilated figures.

It is denoted by "k"

The magnitude of the scale factor is taken into account, and it cannot be zero. The scale factor has the ability to either increase or decrease the size of an object.

The basic formula for calculating the scale factor of a dilated figure is as follows:

Scale = dimension of preimage / dimension of image

According to the question,

(a) If scale factor is less than 1 , k < 1 then the original shape will contract means It's size will decrease

(b) If scale factor is greater than 1 , then image will enlarge and it would expand

The percentage of income that a person or corporation must pay or withhold as taxes is known as the effective tax rate. The effective tax rate is 10.15%. Here option A is the correct answer.

The term effective tax rate refers to the average tax rate that an individual pays on both earned and unearned income, such as stock dividends. According to the progressive tax model, when income rises, the tax rate also rises, putting persons in a higher tax bracket.

Here, the presented data shows that the marginal tax rate is 22% for taxable income in the $40,526 to $86,375 income range.

Effective tax rate = total taxes owed/taxable income × 100.

Effective tax rate = $6,847.50/$67,400 × 100.

Thus, the amount he deposited four years ago is 5600.

Simple interest is used to determine the amount of interest that will be charged on a sum of money at a specific rate and for a specific amount of time. The principal amount in simple interest does not change, in contrast to compound interest, which adds the interest from the principal of preceding years to determine the interest of the following year.

Here,

Given:

The amount of electrician account earned is 1680

thus total amount is = 1680 + x

where x is the principal amount

Interest rate = 7.5%

and total years = 4 years

Using formula

[tex]\frac{P*R*T}{100}[/tex]= Simple interest

=> 1680 = x*7.5*4/100

=>1680 =x * 30/100

=>1680* 100 /30 = x

The permutation combination is 120 for 3 different topping pizzas are available.

Permutation Combination:

A variety of ways to select objects from a set, usually forming a subset without replacement. The selection of this subset is called a permutation if the order of selection is a factor, and a combination if the order is not a factor. The French mathematicians Blaise Pascal and Pierre de Fermat, in the 17th century, used many chances in his game of combinatorics and probability by considering the ratio of the number of required subsets to the number of all possible subsets stimulated the development of the theory.

The concepts of permutations and combinations and their differences can be illustrated by examining all the different ways of selecting pairs of objects from five identifiable objects such as the letters A, B, C, D and E.

Yes. The matrix A-2I is invertible because 2 is an eigenvalue for matrix A.

When the matrix (transformation) is applied to some vectors (eigenvectors), the eigenvalues of the matrix are scalars. In other words, if A is a square matrix of order n x n and v is a non-zero column vector of order n x 1, and Av = v (the product of A and v is just a scalar multiple of v), then the scalar (real number) is called an eigenvalue of the matrix A that corresponds to the eigenvector v.

The eigenvalues can be determined by formula,

[tex]|A-\lambda I|=0[/tex]

Where, [tex]\lambda[/tex] = eigenvalues.A square matrix with an inverse is known as an invertible matrix. A square matrix is said to be invertible if and only if the determinant is not equal to zero. In other words, a 2 x 2 matrix is only invertible if its determinant is not zero.

Given,

A is a 4x4 matrix whose eigen values are λ=1,2,3,4

we need to determine that A-2I is invertible or not.

We know that 2 is an eigen value of matrix A, so, if we substitute 2 to find determinant of A-2I, then we will get zero as answer.
