Briefly answer question below f9g)x))

Answers

Answer 1

We can substitute this value into the function f(x) = 1/(x + 1):

1) f(g(0)) = 1/3

2) g(f(0)) = 4.

To find the value of f(g(0)), we need to first evaluate g(0) and then substitute that result into f(x).

Given the function g(x) = 2x + 2, we can find g(0) by substituting 0 for x:

g(0) = 2(0) + 2 = 0 + 2 = 2

Now that we know g(0) = 2, we can substitute this value into the function f(x) = 1/(x + 1):

f(g(0)) = f(2)

Substituting 2 for x in f(x):

f(2) = 1/(2 + 1) = 1/3

Therefore, f(g(0)) = 1/3.

Now, let's find the value of g(f(0)).

Given the function f(x) = 1/(x + 1), we need to evaluate f(0) and then substitute that result into g(x).

f(0) = 1/(0 + 1) = 1/1 = 1

Now, using the function g(x) = 2x + 2, we substitute f(0) = 1 into g(x):

g(f(0)) = g(1)

Substituting 1 for x in g(x):

g(1) = 2(1) + 2 = 2 + 2 = 4

Therefore, g(f(0)) = 4.

In summary:

f(g(0)) = 1/3

g(f(0)) = 4

Thus, fg(0) = 1/3 and g(f(0)) = 4.

p(-2,6),q(-8,4),r(1,2) what is the y value of p’

Answers

Answer:

OK, here is your answer

Step-by-step explanation:

AI-generated answer

We are given three points, p(-2, 6), q(-8, 4), and r(1, 2), and we are asked to find the y-value of p'. Since we are not given any information about p', we can assume that it is the reflection of p across the x-axis.To find the reflection of p across the x-axis, we need to negate the y-coordinate of p. Therefore, the y-value of p' is equal to the negative of the y-coordinate of p.

So, the y-value of p' is -6.

Hence, the coordinates of p' are (-2, -6).

Simplify i) ( x-y )( x−y )( x−y )

Answers

The simplified expression for ( x - y ) ( x - y ) ( x - y ) is x³ - x²y - xy² + y³.

To simplify ( x - y ) ( x - y ) ( x - y ), we can expand the expression using the distributive property of multiplication. We can also simplify the expression by combining like terms.

In using the distributive property of multiplication, we multiply each term in the first set of parentheses by each term in the second set of parentheses. This gives us:( x - y ) ( x - y ) ( x - y ) = ( x(x - y) - y(x - y) ) ( x - y )= ( x² - xy - xy + y² ) ( x - y )= ( x² - 2xy + y² ) ( x - y )

Now we can further simplify the expression by combining like terms. We can use the difference of squares formula to simplify the second set of parentheses.( x² - 2xy + y² ) ( x - y ) = ( x - y ) ( x - y )²= ( x - y ) ( x² - 2xy + y² )= x³ - x²y - 2xy² + xy² - xy² + y³= x³ - x²y - xy² + y³

Therefore, the simplified expression is x³ - x²y - xy² + y³.

A. The initial value of the linear formula is $40,500

The growth rate of the function is $950

B. The value of the car in 2020 is $69,000

C. The year in which the car is worth $61,400 is 2012.

What is the initial and growth rate value of the linear formula?

.A. V = 40,500 + 950n

Where,

V = value in dollars

n = number of years since 1990

The initial value of the linear formula is $40,500

The growth rate of the function is $950

B. The value of the car in 2020;

When n = 30

V = 40,500 + 950n

= 40,500 + 950(30)

= 40,500 + 28,500

= $69,000

C. The year in which the car is worth $61,400

V = 40,500 + 950n

61,400 = 40,500 + 950n

subtract 40,500 from both sides

61,400 - 40,500 = 950n

20,900 = 950n

divide both sides by 950

n = 22 years

Therefore, 22 years after 1990 is 2012

Given statement solution is :-The decision to renegotiate the egg prices should be based on the calculated probability (P) obtained from the z-score calculation.

To determine whether the diner should renegotiate their egg prices with their vendor, we need to assess the likelihood that the sample mean price will be higher than their current price of $4.75 per dozen. We can use the concept of the sampling distribution of the sample mean to make this assessment.

Given that the population standard deviation is known ($0.75) and the sample size is small (n = 5), we can assume the sampling distribution of the sample mean will be approximately normally distributed. The mean of the sampling distribution will be equal to the population mean ($5 per dozen), and the standard deviation of the sampling distribution (also known as the standard error) can be calculated by dividing the population standard deviation by the square root of the sample size.

Standard error (SE) = population standard deviation / √(sample size)

SE = 0.75 / √(5)

SE ≈ 0.3354

Now, we can calculate the probability that the sample mean price will be higher than $4.75 by standardizing the sample mean using the z-score formula:

z = (sample mean - population mean) / standard error

z = ($4.75 - $5) / 0.3354

z ≈ -0.445

Using a standard normal distribution table or calculator, we can find the probability corresponding to a z-score of -0.445. Let's assume this probability is P.

If P is sufficiently small (typically less than 0.05), it indicates that the sample mean being higher than $4.75 is unlikely to occur by chance. In such a case, it would suggest that the diner should consider renegotiating their egg prices with their vendor.

However, if P is relatively large (greater than or equal to 0.05), it suggests that the sample mean being higher than $4.75 is reasonably likely to occur by chance. In this scenario, there may not be sufficient evidence to justify renegotiating the egg prices based solely on the sample mean.

Therefore, the decision to renegotiate the egg prices should be based on the calculated probability (P) obtained from the z-score calculation.

Solve the following quadratic inequality x^2+x-6>0

Answers

Answer:

x < -3 or x > 2

Step-by-step explanation:

x² + x - 6 > 0

Convert the inequality to an equation.

x² + x - 6 = 0

Factor using the AC method and get:

(x - 2) (x + 3) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x - 2 = 0

x = 2

x + 3 = 0

x = -3

So, the solution is x < -3 or x > 2

Find the function value.
cos (-305.3)°

Answers

Answer:

Step-by-step explanation:

Answer:

The function value.of cos (-305.3)° is 0.5921

Explanation:

To find the value of cos (-305.3)°, we can use the periodicity property of the cosine function. Since cos (x) is a periodic function with a period of 360 degrees, we can add or subtract multiples of 360 degrees from the angle without changing the value of the cosine.

Step 1: Convert -305.3° to an equivalent angle within period one (0 to 360 degrees).

-305.3° + 360° = 54.7°

Step 2: Calculate the cosine of the equivalent angle.

cos (54.7°)

Step 3: Use a scientific calculator or trigonometric table to find the cosine value.

cos (54.7°) ≈ 0.5921

Therefore, the value of cos(-305.3)° is approximately 0.5921

I am writing to seek advice from you with regards to numerous accounting issues. As you know most of our directors have limited accounting knowledge and they are bit confused with the accounting treatment for several items that has been proposed by our junior accountant. Our senior accountant is on sick leave, and we are unsure when she will be back. The directors want to make sure that the proposal by the junior accountant is in line with the requirements of the Australian Accounting Standards. They would also like to understand the reasoning behind the appropriate accounting treatments. The items of concern are included below: The directors are confident that a new toy in the making, Sothies, will be a best seller. During the year ended 30 June 2022, we have incurred $32,000 to identify alternative materials that can be used to manufacture this product. The initial material identified has proven difficult to obtain. Our junior accountant insists that these amounts should be recognised as an expense, but the directors are adamant that the $32,000 should be included as an asset in the balance sheet as it has the potential to produce economic benefits. A preproduction prototype has been developed for Aquadelight, another toy. Aquadelight is a toy meant to be used in the swimming pool and can also be used as a floatation aide. The amount incurred during the year for the preproduction prototype amounted to $55,000. The junior accountant says that there is a possibility that this amount can be recognised as an asset but has not been clear on how to make this determination. Can you please explain in your SoA how to determine if this amount can be recognised as an asset? Please explain the requirements with examples that would be relevant to Aquadelight. The directors are also confused with the terms definition and recognition of an asset. They want to know, why an item that meets the definition of an asset is not necessarily recognised as an asset? 3. The company has a policy of refunding retailers who are dissatisfied with their purchase if the request is made within 14 days. This is a practice of Stumped Limited but is not required by law. This practice is known and frequently utilised by its customers. The directors feel that there is no need to make any accounting entries for this since the refund is not required by law. 4. A court case that has been ongoing for 6 months, relating to Stumped Limited using a manufacturing method that was patented by another toy producer, was finalized on 23 July 2022. Stumped Limited was required to pay damages of $120,000 to the other toy company. A provision of $100,000 was previously provided in relation to this. 5. In January of 2022, the company was sued because a toddler choked on some small parts of a toy manufactured by Stumped Limited and had to be rushed to the emergency department. Luckily the toddler recovered but had to be hospitalized for 2 weeks and this caused the parents a tremendous amount of distress. On 2 July 2022, the court case was still ongoing, and our lawyers felt that the court will find the company liable. The lawyer estimated the amount of damages that may be awarded could be anything between $100,000 to $600,000. The junior accountant has tried to explain the accounting treatment for items 3 to 5, using terms like liability, provision, contingent liability, present obligation, etc., but failed to explain in a way that the directors could understand. Along with your advice for the correct accounting treatment for the above three items, could you also please explain the terms used by the junior accountant?
