hope this helps

The required answer is the (x - 2)^2 + (y + 3)^2 = 25

1. Start by identifying the center of the circle. The center is represented by the coordinates (h, k), where h is the x-coordinate and k is the y-coordinate.

2. Determine the radius of the circle. The radius is the distance from the center to any point on the circle. It can be given directly or you may need to calculate it using the coordinates of two points on the circle.

3. Once you have the center and radius, use the standard form equation of a circle, which is (x - h)^2 + (y - k)^2 = r^2. In this equation, (x, y) represents any point on the circle, (h, k) represents the center, and r represents the radius.

4. To input this equation into a standard form calculator,
  a. Enter the expression for the x-coordinate, (x - h)^2.
  b. Add the expression for the y-coordinate, (y - k)^2.
  c. Input the radius squared, r^2.
  d. Make sure the equation is in the form of (x - h)^2 + (y - k)^2 = r^2.

For example,  a circle with a center at (2, -3) and a radius of 5. To find the equation in standard form,

(x - 2)^2 + (y - (-3))^2 = 5^2

Simplifying further,

(x - 2)^2 + (y + 3)^2 = 25

This is the equation of the circle in standard form.

k = 13The smallest zero or root is x = -10

===============================

Steps:

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+1 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

The 360-degree feedback process is different from other appraisal methods as it involves gathering feedback from multiple sources, including the employee's supervisor, peers, subordinates, and sometimes customers or clients.

The 360-degree feedback process is a performance appraisal method that gathers feedback from multiple sources to provide a comprehensive view of an employee's performance. It involves soliciting feedback from the employee's supervisor, peers, subordinates, and sometimes customers or clients.

This feedback is usually collected through surveys or interviews, and the results are compiled and shared with the employee. By involving multiple sources of feedback, the 360-degree process provides a more complete picture of an employee's strengths and weaknesses than other appraisal methods, which may rely solely on the input of the employee's supervisor.

Therefore, this method allows for a more comprehensive and holistic assessment of an employee's performance.

The cli option on the model statement of an mlr analysis in proc glm is used to produce confidence intervals for the slope parameters.

These intervals provide an estimate of the range of values within which the true slope parameter is likely to lie, given the data and the model that has been fitted to it. Confidence intervals are a useful tool for assessing the uncertainty associated with estimates of model parameters and can be used to determine whether a particular predictor variable is statistically significant or not.

In contrast to prediction intervals, which are used to estimate the likely range of values for a future response variable given a set of predictor variables, confidence intervals are used to estimate the likely range of values for a model parameter, such as a slope coefficient. The cli option can be a valuable tool for interpreting the results of an mlr analysis, as it can help to identify which predictor variables are most strongly associated with the response variable and which may be less important.

Overall, the cli option provides a valuable tool for conducting a thorough and comprehensive analysis of the relationships between predictor and response variables in a given dataset.

Answer:

hello! i just did this problem and the answer is 12.2%

Step-by-step explanation:

first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%

hope this helped plz give me brainliest! <3

The solution is 12.2 %

The percentage of mute swans is given by the equation A = 12.2 %

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage of mute swans be represented as A

Now , the equation will be

Let the total number of swans be S

The number of mute swans = 5  swans

The number of Trumpeter swans = 34 swans

The number of Tundra swans = 2 swans

So , the total number of swans S = 5 + 34 + 2 = 41 swans

And , the percentage of mute swans A = ( number of mute swans / total number of swans S ) x 100

Substituting the values in the equation , we get

The percentage of mute swans A = ( 5/41 ) x 100

On simplifying the equation , we get

The percentage of mute swans A = 0.1219 x 100

The percentage of mute swans A = 12.19

The percentage of mute swans A = 12.2 %

Therefore , the value of A is 12.2 %

Hence , the percentage is 12.2 %

Answer:

Step-by-step explanation:

The odds ratio is \(1.36\) (option b) based on the given table. The odds ratio is a measure of the strength and direction of the association between two categorical variables.

In more detail, the odds ratio is obtained by taking the ratio of the odds of an event in one group (e.g., exposed) to the odds of the event in another group (e.g., unexposed). It provides information on how much more likely (or less likely) the event is to occur in one group compared to the other. An odds ratio greater than 1 indicates a positive association, where the event is more likely in the exposed group. Conversely, an odds ratio less than 1 suggests a negative association, indicating that the event is less likely in the exposed group.

To determine the odds ratio from the given table, you would need to look at the values in the table that represent the exposed and unexposed groups and their respective event frequencies. Without the specific data in the table, it is not possible to provide a more detailed explanation for why option b (\(1.36\)) is the correct answer.

Factor by grouping: 16x³ +28x² - 28x - 49 = 0 is  (4x² - 7) (4x - 7) = 0

Large polynomials can be divided into groups based on a common factor. As a result, we may factor each distinct group and then merge like words. We refer to this as factoring by grouping.

We have the equation,

16x³ +28x² - 28x - 49 = 0

In order to solve the equation by using factor by grouping:

We find common terms in between,

So, we arrange the terms,

16x³ +28x² - 28x - 49 = 0

4x² (4x - 7) -7 (4x - 7) = 0

Here, we have common term (4x-7).

When ball A with diameter d and ball B with diameter 2d are dropped from the same height traveling at the same speed, the ratio of the drag force on ball A to the drag force on ball B is 1:4.

Drag force refers to the force which provides resistance to the motion of an object in a fluid such as air or water. It is given mathematically as:

FD= ½ CDρ v^2 A

Where FD is the drag force, CD is the drag coefficient, ρ is the density of the fluid, v is the velocity and A is the cross sectional area.

As the objects have the same velocity and material drag coefficient, density and velocity is the same. The only difference is the cross-sectional area. Hence to calculate the ratio of drag force for two balls, the ratio of the area would be calculated.

FDA/FDB = πrA^2/ πrB^2 = d^2/(2d)^2 = ¼

Hence, the ratio of the drag force on ball A to the drag force on ball B is 1:4.

Since ∠A and ∠B are vertical angles, they have equal measures, so m∠A = m∠B. We can set the two expressions equal to each other:

7x + 4 = 8x - 20

Solving for x:

-x = -24

x = 24

So, m∠A = 7x + 4 = 7 * 24 + 4 = 188, and m∠B = 8x - 20 = 8 * 24 - 20 = 188.

Therefore, the measure of ∠B is 188 degrees.

The set A ∩ B = {3}

The intersection of sets, denoted as A ∩ B, refers to the set that contains elements that are common to both sets A and B. In this case, set A consists of the elements {1, 2, 3, 6}, and set B consists of the elements {3, 4, 5}.

The intersection of A and B, written as A ∩ B, represents the set of elements that appear in both sets simultaneously.

To find the intersection of sets A and B, we examine each element of set A and check if it is also present in set B. In this case, the element 3 is the only element that exists in both sets.

Therefore, the intersection of sets A and B is {3}.

Evaluate the line integral ∫C xy^2 ds over the right half of the circle x^2 + y^2 = r^2 using appropriate parameterization and integration techniques.

To evaluate the line integral ∫C xy^2 ds, where C is the right half of the circle x^2 + y^2 = r^2, we need to parameterize the curve C and express ds in terms of the parameter.

The right half of the circle x^2 + y^2 = r^2 can be parameterized by x = rcos(t) and y = rsin(t), where t varies from 0 to π.

To find ds, we can use the arc length formula ds = sqrt(dx^2 + dy^2).

Differentiating x and y with respect to t, we have dx/dt = -rsin(t) and dy/dt = rcos(t).

Substituting these values into the arc length formula, we get ds = sqrt((-rsin(t))^2 + (rcos(t))^2) dt = sqrt(r^2) dt = r dt.

Now we can express the line integral in terms of the parameter t:

∫C xy^2 ds = ∫(0 to π) (rcos(t))(rsin(t))^2 (r dt).

Simplifying, we have ∫(0 to π) r^4cos(t)sin^2(t) dt.

This integral can be evaluated using appropriate trigonometric identities and integration techniques.

Answer:

There are 80 oranges in each bag

Step-by-step explanation:

Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

\(88 ft/s= 60 miles/hr\)

Required

Determine the equivalent of 1 mile/hour

\(88\ ft/s= 60\ miles/hr\)

Express 60 as 60 * 1

\(88\ ft/s= 60 * 1\ mile/hr\)

Divide both sides by 60

\(\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}\)

\(\frac{88\ ft/s}{60}= 1\ mile/hr\)

Reorder

\(1\ mile/hr = \frac{88\ ft/s}{60}\)

Divide 88 by 60

\(1\ mile/hr = 1.46666666667\ ft/s\)

Approximate to 3 significant figures

\(1\ mile/hr = 1.47\ ft/s\)
