(x - h)^2 + (y - k)^2 = r^2 is the equation for a circle with center (h, k) and radius (r).

What exactly is a math equation?

A mathematical statement that establishes the equality of two mathematical expressions is the definition of an equation in algebra. Consider the equation 3x + 5 = 14, in which the terms 3x + 5 and 14 are separated by the word "equal."

So, an equation that represents a circle with center (5, -1) and radius of 16 units is:

(x - 5)^2 + (y + 1)^2 = 16^2

or

(x - 5)^2 + (y + 1)^2 = 256

The graph of this equation will be a circle centered at the point (5,-1) with a radius of 16 units.

W = 6 is a solution to the inequality.

In mathematics, Inequality is an unequal comparison between two or more algebraic terms or expressions. The solution of an inequality is a numerical value that will satisfy the given expression.

The signs that we use in Inequality expression are  

'>' - greater than

'<' - less than

'≥' - greater than or equal to

'≤' - less than or equal to

Here we have

Inequality 8 > W

Where the symbol '>' less than indicates 8 is greater than W

or the value of W is less than 8  

As we can see that 6 < 8

Therefore,

W = 6 is a solution to the inequality.

The multiplication of the numbers given to the reduced form is 10/7.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

The given expression is 5 × 2/7

One of the number is a whole number and the other is a fraction.

We can write 5 as 5/1 in terms of fraction and then multiply the numerators and the denominator.

(5/1) × (2/7) = (5×2) / (1 × 7) = 10/7, which is in the lowest form.

Hence the solution of the multiplication is 10/7.

Using division we know that each person will have 1/4 pound of Skittles.

In mathematics, the division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed.

For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The division sign, "," or occasionally "/," is used in computer code.

So, we know that:

Lauren and Shayla have 1/2 pound of Skittles

They will share it with 2 more people.

Then, each will have:

Yes, Chris has enough money to buy 30 folders and 30 pens.

The cost of the stationaries Chris bought are as follows:

Chris wants to buy 30 pens and 30 folders and he has only £60.

Let's check If he has has enough money to buy the products.

Therefore,

3 pens cost £2.25

1 pen  = ?

cost of 1 pen = 2.25 / 3 = 0.75 dollars

5 folders cost £5.80

1 folder = ?

cost of 1 folder = 5.80 / 5 = 1.16 dollars

Hence,

Answer:15 nickels per minute (I believe)

Step-by-step explanation:

First, we want to know how much she got paid in total dollar amount, we'll break it up into nickels later. We know Jackie was paid $45 per hour, but we want to figure out how much per minute she makes. There are 60 minutes in an hour, so divide 45 by 60 ( 45/60 in a calculator).

The answer for 45/60 would then be 0.75. This means Jackie gets paid 75 cents a minute. Since a nickel is worth 5 cents, we just need to divide 75 by 5. Then, we get 15.

Now we know Jackie gets paid 15 nickels per minute. I assume this would be put in aspect ratio form by saying "Jackie gets paid 15 nickels per every one minute of work." but that may depend on how your teacher wants you to word your answer. I hope this helps :)

This polynomial represents the area of the platform.A = w(w + 2)^2. the area of the rectangular platform is 56 square feet and the length of the platform is 2 feet longer than 3 times its width

A = w(w + 2)^2

A = Area of the platform

w = width of the platform

Since the area of the rectangular platform is 56 square feet and the length of the platform is 2 feet longer than 3 times its width, we can represent this statement mathematically as:

A = w(w + 2)^2

This polynomial represents the area of the platform.

A = w(w + 2)^2

A = w^2 + 2w^2

A = 3w^2

A = 56

3w^2 = 56

w^2 = 56/3

w = √56/3

A = w(w + 2)^2, area of the rectangular platform is 56 square feet and the length of the platform is 2 feet longer than 3 times its width.

The eigenvectors of AAH are called the left-singular vectors of A and the eigenvectors of AHA are the right-singular vectors of A . They are called this way because of their use in singular value decomposition. Say A=UΣVH , then the columns of U are the left-singular vectors and the columns of V are right-singular vectors.

We know that the non-zero eigenvalues of AAH  and AHA are the same, they are the squares of the singular values of A . A singular of value of A is a value σ such that Av=σu   AHu=σv where u is a left-singular vector and vs a right-singular vector. This can be taken as the definition of singular value, left-singular vector (which is an eigenvector of AAH) and right-singular vector (which is an eigenvector of AHA).the left-singular and right-singular vector pair works with AAH and AHA

Q: What is the relationship between the eigenvectors of AAT and ATA?

Taking into account the definition of wavelength, frecuency and propagation speed, the wavelength of a wave with a frequency of 4.11×10⁴ Hz is 7299.27 m.

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The propagation speed is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) using the following equation:

v = f×λ

In this case, you know:

v= 3×10⁸ m/s

f= 4.11×10⁴ Hz

λ= ?

Replacing:

3×10⁸ m/s= 4.11×10⁴ Hz× λ

Solving:

λ= 3×10⁸ m/s ÷ 4.11×10⁴ Hz

λ=7299.27 m

In summary, the wavelength of the wave is 7299.27 m.

The total 7 two-player games and 6 six-player games were played.  

Here the total games = 13

And the total number of athletes participated = 50

Let us assume that x represents the total 2-player games played and y represents the total 6-player games played.

The neighborhood holds 13 total games.

So, we get an equation,

x + y = 13                    ................(1)

There are 50 athletes signed up for a neighborhood basketball competition.

So, we get an equation,

2x + 6y = 50                 .............(2)

From equation (1)

x = 13 - y                   ..........(3)

substitute above value of x in equation (2)

2(13 - y) + 6y = 50

26 - 2y + 6y = 50

4y = 24

y = 6

Substitute above value of y in equation (3)

Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The domain of a function is the set of values that we are allowed to plug into our function. While a functions range, is the set of values that the function can take.

The ratios 6:16 and 21:56, 9/11 = 27/15, and y=5x do not form a true proportion. Hence, options A, C, and, D are the correct options.

A true proportion is when both the ratios presented are equal. This can be verified by putting them in their respective fractional form. For example, let's take the ratios in the second option -

= 2/10 and 15/75

Here, we can see that 2*5 = 10 and 15*5 = 75

Hence these can be written as

Therefore, 20.5kg=20.5x2.20462 pounds= 45.195 pounds or 45.195 lb

Additionally we have, 1 lb = 0.35 mEq

Therefore, 45.195 lb=  0.35 mEq × 45.195 = 15.818 mEq.

Also, 8mEq=1 mL

By using unitary method,

1 mEq=1/8 mL

Converting 15.818 mEq to mL, we get

The acute angle formed by the hands of a clock at 4:20a.m is 10°.

For the minute hand, we can compute that, for its every move, it covers 6 degrees. And for the hour hand, each move covers 30 degrees.

A clock is a circle, and a circle always contains 360 degrees. Since there are 60 minutes on a clock, each minute mark is 6 degrees.

The angle between the hour's hand and the minute hand when the clock shows 4:20 pm can be calculated by using the formula:

Angle=|11/2 M-30H|

where M= minute H= hour's

Here M=20 H=4

Therefore we get the angle |11/2(20)- 30*4|=|110-120|=|-10°|=10°
