The domain of the function f(x) = √(x - 5) is x ≥ 5, thus, x = 3 is not in the domain.

Remember that for a function y = f(x), we define the domain as the set of the possible inputs.

Here we have the square root function:

f(x) = √(x - 5)

Remember that the argument of a square root needs to be zero or larger, then the domain of the given function is:

x - 5 ≥ 0

Solving for x:

x ≥ 5

The domain is the set of values equal to or larger than 5, thus, the value 3 is not in the domain.

The outcome that are there when a six sided dice is rolled four times is 2

A sample space is a collection or a set of possible outcomes of a random experiment. The p space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment.

The sample space of getting a 6 from a die is 1. A die has six sides and are labelled 1-6

The angle θ of thread deflection in the extreme position is given by tan^−1(2).

The angle of thread deflection in the extreme position can be calculated by using the equation of motion of a simple pendulum.

The equation of motion for a simple pendulum is given by m g L sinθ = m a. Here, m is the mass of the ball, g is the gravitational acceleration, L is the length of the thread and θ is the angle of the thread.

From the given condition, the acceleration of the ball in the extreme and lowest positions are equal. This implies that the acceleration of the ball in the extreme position is equal to the acceleration due to gravity.

Therefore, the equation of motion reduces to g L sinθ = g. Solving for θ, we get sinθ = 1, which implies that θ = tan^−1(2).

Therefore, the angle θ of thread deflection in the extreme position is given by tan^−1(2).

The row form of the system is 5x = 2 and y – y = 0.

Column form:

3x + y = 5

2x – y = –3

Row form:

3x + 2x = 5 – 3

y – y = 0

The row form of this system is 3x + 2x = 5 – 3 and y – y = 0. To convert from column form to row form, the first step is to eliminate the y terms in the equations. To do this, we need to add the two equations together. This gives us:

3x + y = 5

2x – y = –3

3x + 2x = 5 + (–3)

y – y = 0

5x = 2

y – y = 0

Finally, we can solve for x and y.

5x = 2  ⇒  x = 2/5

y – y = 0  ⇒  y = 0

Therefore, the row form of the system is 5x = 2 and y – y = 0.

Answer:

y = -5x + 7

Step-by-step explanation:

Parallel lines on a graph have the same slopes/gradients.

m1=m2

First you want to rewrite the equation of the graph given. So put the 5x to the other side and you will have:

y = -5x -2

This means that the equation that we need must have the gradient -5 (bc it is m in y=mx+c)

The equation will be y = -5x + c

However we must still find c aka the y intercept.

Sub the point we are given (1,2) into the equation

We will have:

2 = -5(1) + c

2 = -5 + c

7 = c

Now that we know c, we know what the equation of the line is. Just sub it in (without 1 and 2)

use partial fraction decomposition. This involves expressing the rational function as the sum of simpler fractions, each with a pole at a different point in the complex plane. Once we have done this, we can use the formula for the inverse Laplace transform of a simple pole to find the inverse Laplace transform of the original function.

For it to be parallel, the point must follow the translation from (2,7) to that point similar to (0, -3) to (-5, -5) which is left 5 and down 2. So left 5 and down 2 for (2, 7) makes it (-3, 5)

This is a True statement that both the matrix equation and the augmented matrix translate into the same system of linear equations.

What are Linear equations?

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.

A rectangular matrix is a grouping of numbers into rows and columns. Systems of equations can be solved using matrices. But first, we need to understand how to use matrices to represent systems.

An augmented matrix can be used to express a set of equations. Each column in an augmented matrix represents a variable or the constant terms, and each row in an augmented matrix represents one equation in the system. As a result, it is clear that augmented matrices provide a convenient approach to express systems of equations.

Therefore it is true that the solution set of the equation's equation is the same as the solution set of the linear system whose augmented matrix is.

The formula for calculating the number of cards each player receives in Bridge is N/4, where N = number of cards in the deck.

For a standard deck of 52 cards, each player would receive 52/4 = 13 cards. This can be further simplified to 13.33, however, since cards cannot be divided, the result is rounded down to 13 cards. Therefore, each player in a Bridge game with a standard deck of 52 cards will receive 13 cards.

The total number of cards in the deck is 52, so each player will get 13 cards. This can be expressed mathematically using the formula P = 52/4, where P is the number of cards per player. Therefore, P = 13. We can also use the formula to calculate the number of players if we know the total number of cards. For example, if we have 156 cards, the number of players can be calculated using the formula P = 156/4, which gives us P = 39. Therefore, there will be 39 players in the game.
