Answer:

D.)

Step-by-step explanation:

1.) Expand the expression with distributive property. If we expand, we get 10x^2+6xy.

2.) Figure out m and n based on the expression. Since m is in front of the x^2, that means that m=10, and since n is in front of the xy, that means that n=6.
3.) Compute based on m and n. Since m is 10 and n is 6, m - n = 10 - 6 = 4. Therefore, D.) is the answer.

j(m) = 2ᵐ ⁻ ¹

for functions you will replace the number in the brackets with the letter! so:

j(4) = 2⁴ ⁻ ¹

= 2³

= 8

The distance between the mirrors A and C is 80 m.

The Pythagoras theorem tell the relation between the sides of a right triangle, in this we relate the hypotenuse to the other two sides of the triangle, mathematically expresses as- (hypotenuse)² = (Side1)²+(Side)²

Given that, Bill performed a show by placing three mirrors A, B and C in right triangular form, the distance between A and B is 20 m more than the distance between A and C, and the distance between B and C is 20 m less than the distance between A and C,

Let the distance between A and C be x,

AC = x

AB = x+20

BC = x-20

Using Pythagoras theorem,

AB² = AC²+BC²

x²+(x-20)² = (x+20)²

x²+x²+400-4x = x²+400+40x

x²-80x = 0

x(x-80) = 0

x = 0 or x = 80  (Neglecting x = 0 because distance between two sides of a triangle can't be 0)

Hence, The distance between the mirrors A and C is 80 m.

A company's balance sheet is its financial statement at a given point in time and lists its assets, liabilities, equity capital, total debt, and other items.

A balance sheet is a list of all your capital, obligations, and assets. The assets and liabilities of a firm are described in detail on a balance sheet, which is a financial statement.

The Equity Section of the Nortech Corporation's Balance Sheet exists as follows:

Common Stock:

500,000 shares, Authorized at $1 par value

200,000 Issued Shares at $1 = $200,000

Additional Paid-in Capital          4,143,000

3,000 shares, Treasury stock        (3,000)

Retained Earnings                       253,500

Total Equity                           $4,593,500

1c. Shares Outstanding = 197,000 (200,000 - 3,000)

2. Balance in Additional Paid-in Capital = $4,143,000

3. Earnings per share = $0.75 ($147,750/197,000)

4. Dividend per share = $0.25 ($49,250/197,000)

5. The Treasury stock is reported as $3,000 on the balance sheet.

6. With a 2-for-1 stock split, the par value becomes $0.50 ($1/2)

Data and Calculations:

Par value of Common Stock = $1

Authorized Shares = 500,000 shares

Issue price per share = $22

Common Stock Account = $200,000

Issued Shares = 200,000 shares ($200,000/$1)

Treasury Stock = $3,000 (3,000 x $1)

Additional Paid-in Capital = $4,200,000 (200,000 x $21)

Additional Paid-in Capital (Treasury Stock) = $57,000 ($19 x 3,000)

Balance of Additional Paid-in Capital = $4,143,000 ($4,200,000 - $57,000)

Retained earnings for the year:

What is Fibonacci sequence?

One of the most well-known mathematical formulae is the Fibonacci sequence. Each number in the Fibonacci sequence is calculated by adding the two numbers that came before it. Typically, the Fibonacci series' first two terms are 0 and 1. Hundreds of years before Leonardo Pisano Bigollo was even aware of it, the Fibonacci sequence was well-known in India. Because the date November 23 contains the numbers "1, 1, 2, 3," which are a part of the sequence, it is recognized as Fibonacci Day.

it's congruent

The value of x, in dollars, so that they have equal weekly pay is $18,000.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h. The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved. Co-domain is a set of values that have the potential of coming out as outputs of a function.

We are given that Guy and Jim earn the same weekly pay.

Then g(x) = f(x)

So, 185 + .03x = 275 + .025x

Rearranging terms so that the x's are together and the constants are together:

0.005x = 90

∴ x =  18,000

Thus, the value of x, in dollars, so that they have equal weekly pay is $18,000.

I hope you understand this now.

if not please let me know what is still a "riddle" to you, so that I can explain it better.

remember, the inverse function of y = e^x is x = ln(y).

and the inverse function of y = ln(x) is x = e^y.

we want to find the value of x, where f(x) = 28.

28 = 0.48ln(x + 2) + 27

1 = 0.48ln(x + 2)

1/0.48 = ln(x + 2)

e^(1/0.48) = x + 2

x = e^(1/0.48) + 2 = 10.03119499... miles ≈ 10 miles

the pressure of 28 inches of mercury occurs about 10 miles from the eye of the hurricane.

What is the system of linear equations in matrices?

A system of linear equations in matrices is a set of linear equations that can be expressed in matrix form. In this form, the equations are written as a matrix equation of the form Ax = b, where A is an m × n matrix of coefficients, x is an n × 1 matrix of variables, and b is an m × 1 matrix of constants. The solution to the system of equations can be found by solving for the matrix x using the matrix equation Ax = b. This can be done using various techniques, such as Gaussian elimination or matrix inversion. Matrix equations can be used to solve systems of linear equations for which the traditional algebraic methods are difficult or impossible.

We can prepare the equations as:

Equation 1: 6x - 4y = 3

Equation 2: 2x + 4y = -2

Hence, the equations of the system would be 6x - 4y = 3 and 2x + 4y = -2.

The dimension of the square piece of paper is 6 inches.

A rectangular piece of paper is twice as long as a square piece and 3 inches wider.

The area of the rectangular piece is 108 in².

A square has all its side equal to each other and a rectangle has two opposite sides equal to each other.

Therefore,

let

x = length of the square

Therefore,

length of rectangular piece = 2x

width of the rectangular piece = 3 + x

Therefore,

area of the rectangular piece = lw

where

Therefore,

area of the rectangular piece = 2x(3 + x)

area of the rectangular piece = 6x + 2x²

108 = 6x + 2x²

2x² + 6x - 108 = 0

divide through by 2

x² + 3x - 54 = 0

x² - 6x + 9x - 54 = 0

x(x - 6) + 9(x - 6) = 0

(x + 9)(x - 6)

Therefore, we can only use positive numbers.

Step-by-step explanation:

At 45, is the median value. The median of a box plot is not necessarily 50% of the data. The median is the middle value in a dataset, or the value that divides the data into two equal halves. If the dataset has an odd number of values, the median will be one of the values in the dataset. If the dataset has an even number of values, the median will be the average of the two middle values.

Answer:

If the local office supply store sells 5 packs of paper, it also sells 8 packs of envelopes. This means that the store sells 8 packs of envelopes for every 5 packs of paper.

If the store sells 15 packs of paper, it will sell 15 packs of paper * (8 packs of envelopes / 5 packs of paper) = <<15*(8/5)=24>>24 packs of envelopes.

Therefore, if the local office supply store sells 15 packs of paper, it will sell 24 packs of envelopes.

Over the course of many​ games, one would expect the mean number of hits per game to be the mean of the random variable.

What is Mean?

A group of two or more numbers is simply averaged mathematically to get the term "mean." There are several ways to calculate the mean for a given collection of numbers, including as the arithmetic mean approach, which utilises the sum of the series' values, and the geometric mean method, which uses the average of a group of products. However, the majority of the time, the results from all of the main approaches to calculating a simple average are roughly the same.

There are two different types of means that can be calculated: the arithmetic mean and the geometric mean.

The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of numbers in the set.

Mean is the ratio of sum of observations to the total number of observation.
