The point (11,10) lies on the circle with center (5,2).

The equation of the circle with center (5,2) and point (11,10) is given by [tex](x-5)^2 + (y-2)^2 = (x-11)^2 + (y-10)^2.[/tex]

Substitute the coordinates of the center and point in the equation and simplify, we get

[tex](x-5)^2 + (y-2)^2 = (x-11)^2 + (y-10)^2= (x-5)^2 + (y-2)^2 = (x-11)^2 + (y-10)^2= x^2 - 10x + 25 + y^2 - 4y + 4 = x^2 - 22x + 121 + y^2 - 20y + 100= -10x + 25 - 4y + 4 = -22x + 121 - 20y + 100= -10x - 22x = 121 - 25 - 20y + 4y=-32x = 96= x = 3[/tex]

Substitute this value of x in [tex](x-5)^2 + (y-2)^2 = (x-11)^2 + (y-10)^2[/tex] and simplify, we get

[tex](3-5)^2 + (y-2)^2 = (3-11)^2 + (y-10)^2= (-2)^2 + (y-2)^2 = (-8)^2 + (y-10)^2= 4 + y^2 - 4y + 4 = 64 + y^2 - 20y + 100= -4y + 8 = -20y + 96= 16 = 16[/tex]

To use regrouping to solve, we need to add and subtract the numbers in the expression, taking care to keep track of any negative signs.

10 - 1 - 1 - 6 - ² - 2

= 10 - (1 + 1) - 6 - ² - 2 [Group the first two numbers together and add them]

= 10 - 2 - 6 - ² - 2 [Simplify the first three terms]

= (10 - 2) - 6 - ² - 2 [Group the first two terms together and subtract them]

= 8 - 6 - ² - 2 [Simplify the first two terms]

= 2 - ² - 2 [Simplify the first two terms]

= -1 [Simplify the expression by subtracting ² and 2 from -1]

Therefore, the final answer is -1.

Therefore, the equation in slope-intercept form that has a y-intercept at (0, -3) and also contains the point (4, 5) is y = 2x - 3.

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of variables, constants, and mathematical operators such as addition, subtraction, multiplication, and division. An equation is usually written with an equal sign (=) between the two expressions. Equations are used to represent mathematical relationships between quantities, to solve problems, and to model real-world situations. They can be used to find unknown values, to predict outcomes, and to test hypotheses. There are many types of equations, including linear equations, quadratic equations, polynomial equations, trigonometric equations, and differential equations. Each type of equation has its own rules and methods for solving it.

Here,

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. We are given that the y-intercept is (0, -3), so b = -3. To find the slope, we can use the two given points (0, -3) and (4, 5).

slope = (y2 - y1)/(x2 - x1)

= (5 - (-3))/(4 - 0)

= 8/4

= 2

Explanation

Add up the frequencies:

7+6+12+19+19 = 63

Out of those 63 total spins, 6 of them landed on blue.

The empirical (aka experimental) probability of landing on blue is therefore 6/63 = 2/21

The hypotenuse's length could therefore be between 9.03 and 10.70 units based on these estimates.

The term "right triangle" refers to a triangle with an internal angle of 90 degrees. The hypotenuse, the side that faces the right angle and is also the side with the longest side in a right triangle, and the height and base are the two limbs of the right angle.

Based on the information provided, it is reasonable to infer that we have a right-angled triangle with two sides that are y and 7, and we need to determine the length of the hypotenuse.

The hypotenuse's square length is equal to the total of the squares of the lengths of the other two sides, according to the Pythagorean theorem.

The result is:

y² + 7² = hypotenuse²

hypotenuse² = y² + 49

we can determine the length of the hypotenuse by assuming that y is somewhere between 5.7 and 8.1.

If y is 5.7, then:

hypotenuse² = 5.7² + 49

hypotenuse² = 81.49

hypotenuse ≈ 9.03

If  y is 8.1, then:

hypotenuse² = 8.1² + 49

hypotenuse² = 114.61

hypotenuse ≈ 10.70

So, based on these estimations, the length of the hypotenuse could be around 9.03 or 10.70 units.

The sum of (8a + 2b - 4) and (3b - 5) is (8a + 5b - 9). We can find it in the following manner.

To find the sum of (8a + 2b - 4) and (3b - 5), we can simply add the corresponding coefficients of the variables a and b, as well as any constant terms.

So we have:

(8a + 2b - 4) + (3b - 5)

= 8a + 2b + 3b - 4 - 5 (grouping like terms)

= 8a + 5b - 9

Therefore, the sum of (8a + 2b - 4) and (3b - 5) is (8a + 5b - 9).

We can also explain this process by using the distributive property of addition over subtraction. This property states that the sum of two numbers with the same sign (positive or negative) can be found by adding their absolute values and keeping the common sign.

In this case, we can think of the expression (8a + 2b - 4) as the sum of three terms: 8a, 2b, and -4. Similarly, we can think of the expression (3b - 5) as the sum of two terms: 3b and -5.

Using the distributive property, we can add the terms with the same variable together:

(8a + 2b - 4) + (3b - 5)

= 8a + (2b + 3b) - (4 + 5)

= 8a + 5b - 9

Thus, we obtain the same result.

The cost of the concrete used to make the cylinder was approximately $6,776.89.

The problem is asking us to find the cost of the concrete used to make a cylindrical pillar, given its dimensions and the cost per cubic meter of concrete. We first need to calculate the volume of the cylinder using the formula for the volume of a cylinder:

[tex]V=pir^2h[/tex]

where V is the volume, r is the radius, h is the height, and π is the constant pi (approximately 3.14159).

In the problem, the diameter of the cylinder is given as 4 meters, which means the radius is half of that, or 2 meters. The height of the cylinder is given as 5 meters.

Substituting these values into the formula, we get:

[tex]V = \pi r^2h = \pi (2)^2(5) = 20\pi cubic meters[/tex]

Next, we need to find the cost of the concrete used to make the cylinder, given that the cost per cubic meter of concrete is $107. We can do this by multiplying the volume of the cylinder by the cost per cubic meter of concrete:

20π × $107 = $6,776.89

Rounding to the nearest cent, we get that the cost of the concrete used to make the cylinder was approximately $6,776.89.

If the distribution of values is normal with a mean of 93.2 and a standard deviation of 87.4. the score separating the bottom 81% from the top 19% is 168.24.

 The value of p81, which is the score separating the bottom 81% from the top 19%, can be calculated as follows:

 The given, Mean = μ = 93.2

                    Standard deviation = σ = 87.4

      We are supposed to find the score separating the bottom 81% from the top 19% which is nothing but the 81st percentile.

       Let X be a random variable with a normal distribution, then the z-score of the 81st percentile is calculated as follows:

               z = InvNorm(0.81)

               z ≈ 0.8 (by standard normal distribution tables)

    The 81st percentile in terms of X is given by:

              p81 = μ + zσp81

                     = 93.2 + 0.8(87.4)p81

When it comes to representing a decrease in the amount of something, the easiest way is to use negative values.

In this case, option C, Negative 1/3 is the correct choice.

The fraction 1/6 means that the container has 1 part of the original 6 parts of the yogurt left.

However, this shows the remaining amount of yogurt in the container, not the decrease.

Therefore, we can say that the fraction 1/6 is not the correct choice in this context.

In a linear equation, a first-degree polynomial is defined as the sum of a group of terms, where each term is the product of a constant as well as the initial power of a variable.

The linear equation using the slope intercept form is -

Y = mX + b,

where, Y - number of cards

Slope = (y2 - y1)/(x2 - x1),

y2=500 cards, y1=200 cards, x2=$35, and x1=$23.

m = (500-200)/(35-23) = 300/12

m = 25.

Now,  slope m = 25, apply slope-intercept formula to find y when x=0.

Y = mX + b,

25 = (200 - y)/(23-x),

At,  x=0,

25 = (200-y)/23

200 - y = 25*23

Answer:

Step-by-step explanation:

Since Shen drove at the same rate for both distances, we can use a proportion to solve for the time it would take him to drive 335 miles:

[tex]\frac{d_{1} }{t_{1} }=\frac{d_{2} }{t_{2} }[/tex]

where d1 is 603 miles, t1 is 9 hours, d2 is 335, and t2 is the unknown value.

Thus, we can simply plug in everything to the equation and solve for t2:

[tex]\frac{603}{9}=\frac{335}{t_{2} }\\ 67=\frac{335}{t_{2} }\\ 67t_{2}=335\\ t_{2}=5[/tex]

(*Note that 9 divides evenly into 603 and becomes 67, which is why I didn't cross-multiply first with he 603 and t2 and the 335 and 9, although you'd still get the same result for t2)

Thus, it would take Shen 5 hours to drive 335 miles.

You can check by finding the rate for both equations since we know that distance is equal to the product of rate and time (d = rt):

First equation:  603 miles = 9 hours * r mph

67 mph = r

603 = 67 * 9

Second equation: 335 miles = 5 hr * r mph

67 mph = r

335 = 67 * 5

(a) To classify the behavior of the system, we can use the (A,T) chart. Here, A is the sum of the elements in each row of the system matrix and T is the sum of the absolute values of the off-diagonal elements.

The system matrix for this scenario is:

[ 0   1 ]

[-1   1 ]

So, A = 1 for both rows, and T = 1 (absolute value of the off-diagonal element).

Using the (A,T) chart, we can see that the system is a focus.

(b) To find the eigenvalues and eigenvectors of the system, we need to solve the characteristic equation:

| 0-lambda  1       |   |u|    |0|

| -1        1-lambda| [tex]\times[/tex] |v| =  |0|

Expanding the determinant, we get:[tex]\lambda^2[/tex] -[tex]\lambda[/tex] + 1 = 0

Solving for lambda using the quadratic formula, we get:[tex]\lambda[/tex] = (1 +/- sqrt(3)i) / 2

So, the eigenvalues are complex conjugates with a real part of 1/2. The eigenvectors can be found by solving the system of linear equations:(0 - lambda)u + v = 0

(-1)u + (1 - lambda)v = 0

For lambda = (1 + sqrt(3)i) / 2, we get:u = [1, -1 + sqrt(3)i]

For lambda = (1 - sqrt(3)i) / 2, we get:u = [1, -1 - sqrt(3)i]

(c) To sketch the solution curve that starts at R(0) = 1, J(0) = 1, we can use the eigenvectors and eigenvalues. The general solution for the system can be written as:[x(t), y(t)] = [tex]c_1 \times u_1 \times e^(l \ambda1 \times t) + c2 \times u2 \times e^(\lambda2 \times t)[/tex]

where c1 and c2 are constants determined by the initial conditions, u1 and u2 are the eigenvectors, and lambda1 and lambda2 are the eigenvalues.

Plugging in the values, we get:

[tex][x(t), y(t)] = c_1 \times [1, -1 +\ sqrt(3)i] \times e^{((1 + \sqrt(3)i)t} / 2) + c_2\times [1, -1 - \sqrt(3)i] \times e^{((1 - \sqrt(3)i)t} / 2)[/tex]

Using the initial condition R(0) = 1, J(0) = 1, we get:

[tex]c_1 + c_2 = 1[/tex]

(-1 + sqrt(3)i)c1 + (-1 - sqrt(3)i)c2 = 1

Solving for [tex]c_1[/tex] and [tex]c_2[/tex], we get:

[tex]c_1[/tex] = (1 + sqrt(3)i) / (2[tex]\times[/tex] sqrt(3)i)

[tex]c_2[/tex]= (1 - sqrt(3)i) / (2 [tex]\times[/tex] sqrt(3)i)

Plugging in these values, we get:

[x(t), y(t)] = [1, 0] [tex]\times[/tex] e^((1 + sqrt(3)i)t / 2) + [0, 1] [tex]\times[/tex]  e^((1 - sqrt(3)i)t / 2)

200 m/s  is the wave speed of a wave that has a frequency .

What do you name a wave?

There are two different types of waves: longitudinal and transverse. Longitudinal waves are similar to those of sound in that they alternate between compressions and rarefactions in a medium, much like transverse waves in that the surface of the medium rises and falls.

                             The pattern of disruption brought about by the movement of energy through a medium (such as air, water, or any other liquid or solid matter) as it spreads away from the source of the sound is known as a sound wave.

The wave speed (v) of a wave can be calculated by multiplying its frequency (f) by its wavelength (λ). Mathematically, we can express this as

v = f x λ

Substituting the given values of frequency and wavelength into this formula, we get:

v = 500 Hz x 0.40 m

Multiplying these values, we get:

v = 200 m/s

Therefore, the wave speed of a wave that has a frequency of 500 Hz and a wavelength of 0.40 m is 200 m/s.

Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, 50% means 50 out of 100 or 50/100, which is equivalent to the fraction 1/2 or the decimal 0.5.

Percentages are commonly used to express proportions, rates, or changes. They are used in many different fields, such as finance, statistics, science, and everyday life. For instance, we might use percentages to describe the rate of interest on a loan, the percentage of people who have received a vaccine, or the percentage increase or decrease in the stock market.

by the question.

First, we need to calculate the total fee the attorney will earn based on the hourly rate and the percentage of the settlement.

The attorney's fee is the sum of the hourly fee and the percentage of the settlement:

hourly fee = 110 hours x $175 per hour = $19,250

percentage of the settlement = 25% of the settlement

total fee = hourly fee + percentage of the settlement

We know that the total fee must be greater than or equal to $45,000, so we can set up an equation to solve for the minimum acceptable settlement:

$19,250 + 0.25S ≥ $45,000

where S is the settlement amount.

Subtracting $19,250 from both sides, we get:

0.25S ≥ $25,750

Dividing both sides by 0.25, we get:
