what is unitary method ?

To answer mathematical issues involving proportional relationships between two or more quantities, one uses the unitary method. It is a technique for determining the value of one unit depending on the value of another, in other words. In several disciplines, including mathematics, physics, economics, and engineering, the unitary technique is frequently utilized. Finding the value of a single unit of a given quantity and using that value to calculate the value of a desired number of units is what this process entails.

given

The initial amount of water plus the water that has been added over time equals the total amount of water in the pond at any one time. We can apply the following formula because the rate of water addition is constant at 28 liters per minute:

W = 600 + 28T

where W is the pond's total volume of water (measured in liters), and T is the passing of time (in minutes).

T = 12 can be used in the equation to determine how much water was in the pond overall after 12 minutes:

W = 600 + 28T

W = 600 + 28(12) (12)

W = 600 + 336

W = 936

Hence, after 12 minutes, there are 936 liters of water in the pond overall as the rate of water addition is constant at 28 liters per minute.

Answers

Step-by-step explanation & Answer:

It's easier to compare two functions if you can compare them by graphs.

The first function is a polynomial function - try your best to put these in standard form so that you can see where the roots/x-intercepts are. You can set the function equal to zero to find the roots, as well as set x=0 to find our y-intercept.

The second function is an exponential function.  These always diverge ("shoot off") to positive infinity on the y-axis, and are asymptotic on the x axis, diverging to negative infinity. The only difference is made by a +5 here...that is a ENTIRE vertical shift up of 5 units <— Answer! Exponential functions also have a special y-intercept...think about what will happen if this intercept is shifted up 5 units.

Answers

A violation of substantive due process (B)A new law fines book publishers for printing content that is considered unpatriotic. A drug dealer with several prior convictions is sent to prison without a trail.

The procedural rights guaranteed by the United States Constitution ensure that all citizens are treated equally before the law. For example, all citizens have the right to a lawyer, to a public and speedy trial, to have their case judged by a jury of their peers, etc.

In Scenario B, the drug dealer's rights are violated by law enforcement. Even if he has a criminal record, law enforcement has no right to immediately throw him in jail.

Due process is the application of all legal rules and principles relating to a case by the state to uphold all legal rights of individuals. Due process balances the power of the laws of the land and protects individuals against the laws. When the government harms a person without following the exact procedure of the law, it is a violation of due process and violates the rule of law.

It is the constitutional process in which the federal government before denying a citizen the right to life, liberty, or freedom, must give proper notice to the person, the opportunity of being heard, and the decision is taken without any discrimination. The act which violates the Procedural due process is giving a driver a traffic ticket without telling him, his right, i.e, can appeal in court against it.

In order to find the diagonal we need the length of the two other sides. One of those is twelve, the other is unknown; we’ll call it x.

Side X cuts the bottom the rectangular prism in half by the diagonal, this creates two triangles with sides 4, 3, and x.

X is the hypotenuse, meaning we can use Pythagorean theorem (a^2 +b^2 = c^2)

4^2 + 3^2 = x^2
25 = x^2
5=x

The height of the diagonal triangle is 12 and the base is 5.
We can use the Pythagorean theorem again

To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

Answers

It is TRUE that If you want to calculate the total magnification, take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

If you want to get the total magnification of a microscope, you need to multiply the magnification of the objective lens by the magnification of the eyepiece lens. The objective lens typically has a magnification of 4X, 10X, or 40X, and the eyepiece lens usually has a magnification of 10X. So, for example, if you are using a 10X objective lens and a 10X eyepiece lens, the total magnification would be 10 × 10 = 100X.

On the other hand, these numbers may be the total magnification for a lower powered stereomicroscope. 10X and 40X are achievable with 10X eyepieces and 1X or 4X objective lenses. Or it can be a zoom stereomicroscope with zoom set to 1X and 4X and 10X eyepieces. To get a total of 4X, you can use the 0.8X zoom setting (which is common) plus the 5X eyepiece. Or you can use the 0.5x auxiliary lens, 0.8x zoom and 10x eyepieces.

What are the solutions to the equation 2x2 + 12x =26

Answers

The solutions to the equation 2x² + 12x = 26 are x = -7 and x = 1.

How to solve equation?

To solve the equation 2x² + 12x = 26, we need to bring all the terms on one side of the equation and then factorize or use the quadratic formula to find the values of x that satisfy the equation.

First, we can simplify the equation by dividing both sides by 2 to get:

x² + 6x = 13

Now, we can bring all the terms to one side by subtracting 13 from both sides:

x² + 6x - 13 = 0

To factorize the quadratic expression, we need to find two numbers that multiply to give -13 and add to give 6. These numbers are 7 and -1, since 7 * -1 = -7 and 7 + (-1) = 6. So we can rewrite the equation as:

(x + 7)(x - 1) = 0

Now we can use the zero product property to find the values of x that satisfy the equation:

x + 7 = 0 or x - 1 = 0

Solving for x in each equation, we get:

x = -7 or x = 1

Therefore, the solutions to the equation 2x² + 12x = 26 are x = -7 and x = 1.

An anthropologist is interested in the relationship
between fathers' and sons' heights. She collects a
simple random sample of 25 fathers and 25 sons, and
determines that the least-squares regression line is ý = -
2.8+ 1.1x, where ŷ is the predicted height of each son
and x is the height of his father (both measured in
inches).
One father is 72 inches tall, and his son is 75 inches tall.
What is the residual for the son's height?
O -2.8
O-1.4
O 1.1
O 1.4

Answers

Answer: B. -1.4

Step-by-step explanation:

 To find the residual, we need to first calculate the predicted height of the son using the given regression equation:

ŷ = -2.8 + 1.1x

where x is the height of the father. For the given father who is 72 inches tall, we have:

ŷ = -2.8 + 1.1(72) = 75.6

So the predicted height of the son is 75.6 inches.

The residual is then calculated by subtracting the predicted height from the actual height of the son:

residual = actual height - predicted height

= 75 - 75.6

= -0.6

Therefore, the residual for the son's height is -0.6, which is closest to answer B after rounding to one decimal place.

the coefficient of determination measures the variation in the dependent variable that is explained by the regression model.T/F

Answers

The statement "the coefficient of determination measures the variation in the dependent variable that is explained by the regression model" is true because coefficient of determination, or R-squared, measures the proportion of variance in the dependent variable that is explained by the independent variables in a regression model.

The coefficient of determination, or R-squared, is a statistical measure that evaluates the goodness of fit of a regression model. It quantifies the amount of variance in the dependent variable that can be explained by the independent variables in the model. R-squared ranges from 0 to 1, where a value of 0 means that none of the variation in the dependent variable is explained by the model, while a value of 1 indicates that all the variation is explained.

Therefore, R-squared is useful in assessing the predictive power of a model, and higher values are generally preferred. However, it is important to note that R-squared alone does not guarantee a good model, and other factors such as model assumptions and outliers should also be considered.

Total number of men is equals to 531

Total number of heavy smoker is equals to 90

Man and Heavy smoker are mutually exclusive events.

Let 'M' represents man

And 'H' represents heavy smoker

Probability of randomly selected person is a man or a heavy smoker

= P( M ∪ H )

= Probability of a man  + Probability of a heavy smoker

= P( M ) + P (H)

= ( 531 / 1124 ) + ( 90 / 1124 )

Deposit is money held in a bank account or with another financial institution that requires a transfer from one party to another.

If Carter had a total of $50 in his bank account at the start of the month and made deposits totaling $150 during the month, then he had a total of $200 in his account during the month.

Since he still had a total of $50 in his account at the end of the month, it means that he must have spent or withdrawn $150 during the month, which is equal to the total amount of deposits he made.

Therefore, the statement that must be true is: Carter withdrew or spent $150 during the month.

A cuboid is a solid or three-dimensional shape in geometry. A cuboid is a convex polyhedron with 8 coordinates, 12 sides, but rather 6 rectangular faces. A cuboid is another name for it. A box is a cuboid because it has six square faces. Objects unearthed in boxes include bricks and books. The following are the primary distinctions between cubic and cubic: In contrast to a cube's rectangular faces, the faces of a capsule are perfectly straight and equal in size. But even though the structures of both the cube and cuboid are similar, they differ significantly in terms of side length, horizontal, and area.

the volume of the block is:

Volume = length x width x height

Volume = 2 ft x 3 ft x 1.5 ft
