Replace x with 1 nd solve, then replace x with 3 and solve:
x^3 - 2x^2 +3x
When x = 1: 1^3 -2(1)^2 +3(1) = 3 -3 +3 = 3
When x = 3: 3^3 -2(3)^2 + 3(3) = 27 -18 +9 = 18
The difference between the two solutions is 18-3 = 15
The difference between the two x values = 3-1 = 2

Mr. Oswald, the head of human resources, has
been in the company for 24 years, which
corresponds to three times as many as the
number of years Mrs. Bright, the finance
director, is also employed there.
Considering neither of them leaves their jobs,
how many years will Mr. Oswald have worked for
the company when that corresponds to twice as
many as Mrs. Bright's number of years there?
Answers
Mrs. Bright has worked for 8 years, and Mr. Oswald has already worked for 24 years, which is more than Twice the number of years Mrs. Bright has worked.
The number of years Mrs. Bright has worked for the company. We know that Mr. Oswald has been in the company for 24 years, which is three times the number of years Mrs. Bright has worked.
So, Mrs. Bright has worked for 24 / 3 = 8 years in the company.
Now, let's find the number of years Mr. Oswald needs to work for the company to make it twice the number of years Mrs. Bright has worked.
Twice the number of years Mrs. Bright has worked is 2 * 8 = 16 years.
Since Mr. Oswald is already employed for 24 years, we need to find the additional years he needs to work to reach 16 more years.
16 more years - 24 years = -8 years.
The result of -8 years indicates that Mr. Oswald has already worked for more than twice the number of years Mrs. Bright has worked. Therefore, it is not possible for Mr. Oswald to work for more years in order to make it twice the number of years Mrs. Bright has worked.
Mrs. Bright has worked for 8 years, and Mr. Oswald has already worked for 24 years, which is more than twice the number of years Mrs. Bright has worked.

The area of the sector is 297π units squared.
How to find the area of a sector?The arc length of a 330° sector is 33π. Therefore, let's find the area of the sector.
Let's find the radius of the circle.
length of arc = ∅/ 360 × 2πr
where
∅= central angler = radiusTherefore,
33π = 330 / 360 × 2π × r
cross multiply
660πr = 11880π
divide both sides by 660π
r = 11880π / 660π
r = 18 units
Therefore,
area of the sector = 330 / 360 × π × 18²

Danielle Stevenson receives a commission of 6.5% for selling a $160,000 house. One-half of the commission goes to the broker, and one-half of the remainder to another salesperson. Stevenson receives the rest. Find the amount she receives.
Answers
Answer:
Danielle Stevenson receives $2,600 from selling the $160,000 house.
Step-by-step explanation:
To find the amount Danielle Stevenson receives from selling the house, we'll follow these steps:
Calculate the commission earned by Danielle Stevenson: Commission = 6.5% * $160,000.
Commission = 0.065 * $160,000 = $10,400.
Determine the broker's share: Broker Share = 0.5 * Commission.
Broker Share = 0.5 * $10,400 = $5,200.
Calculate the remaining amount after the broker's share: Remaining Amount = Commission - Broker Share.
Remaining Amount = $10,400 - $5,200 = $5,200.
Determine the salesperson's share: Salesperson Share = 0.5 * Remaining Amount.
Salesperson Share = 0.5 * $5,200 = $2,600.
Finally, calculate the amount Danielle Stevenson receives, which is the remaining portion after the broker and salesperson's shares: Amount Danielle Receives = Remaining Amount - Salesperson Share.
Amount Danielle Receives = $5,200 - $2,600 = $2,600.
Therefore, Danielle Stevenson receives $2,600 from selling the $160,000 house.

2 right-angled triangles (left and right).
1 rectangle in the back.

the area of a right-angled triangle is
leg1 × leg2 / 2

Identify a situation that would fit into this scenario and explain how would you organize this calculation to solve it without a calculator. Assume a 5% sales tax rate. For full credit, you will need the cost of the it, an explanation of how you would calculate the sales tax and the total cost.
Answers
You would add the sales tax amount to the cost of the meal to get the total cost. In this case, the sales tax amount is $1, so the total cost would be $26.
One situation that would fit into this scenario is calculating the total cost of a meal at a restaurant that costs $25. Firstly, to calculate the sales tax, you would need to convert the percentage of sales tax into a decimal.
In this case, the sales tax rate is 5%, so you would convert it to 0.05.Next, you would multiply the cost of the meal by the sales tax rate to calculate the sales tax amount.
To do this calculation without a calculator, you can use mental math or estimation techniques.For example, you could estimate 5% of $25 by breaking the 5% into a 1% and 4% calculation.
To calculate 1%, you would simply move the decimal point two places to the left, which gives you $0.25. Then, to calculate 4%, you could multiply $0.25 by 4, which equals $1.

On January 1 2019, a company reported assets of $1500000 and liabilities of $700000. During 2019, assets decreased by $100,000 and stockholders equity decreased $200,000. What is the amount of liabilities at December 31 2019? Enter your answer to the nearest whole number
Answers
The amount of liabilities at December 31, 2019, is $900,000.
To determine the amount of liabilities at December 31, 2019, we can use the accounting equation:
Assets = Liabilities + Stockholders' Equity
Given that the company reported assets of $1,500,000 and liabilities of $700,000 on January 1, 2019, we can set up the equation as follows:
$1,500,000 = $700,000 + Stockholders' Equity
During 2019, assets decreased by $100,000, so the new value of assets at December 31, 2019, would be $1,500,000 - $100,000 = $1,400,000.
Stockholders' equity decreased by $200,000, so the new value of stockholders' equity at December 31, 2019, would be $700,000 - $200,000 = $500,000.
Now we can substitute these values into the accounting equation to solve for liabilities:
$1,400,000 = Liabilities + $500,000
Rearranging the equation, we find:
Liabilities = $1,400,000 - $500,000
Liabilities = $900,000
Therefore, the amount of liabilities at December 31, 2019, is $900,000.

The acceleration due to gravity on Earth is approximately 9.81 m/s².
So, the weight of an object with a mass of 12 kg is:
weight = 12 kg x 9.81 m/s² = 117.72 N
Therefore, the weight of the object is approximately 117.72 Newtons.
Two forces of 5N and 12N act at right angles to each other. Use a graph paper to determine the magnitude and direction of the resultant force graphically. State the scale you use to represent each vector. You will need a protractor to measure the angle the resultant makes with the 5N force.
Answers
The resultant of the force that acts in opposite directions is 7 N.
We have,
We know that the resultant force is the force that has the same effect in magnitude and direction as two or more forces that is acting together. We have to note that the force that is actinmg on an object is a vector quantity. The implication of this is that the magnitude and the direction of the forces that are acting on the body is very important.
By the use of the law of vectors we can be able to write in the case of the question that we have here, we can see that the forces are acting in the opposite directions. The implication of this is that we would have to subtract the forces so as obtain the resultant force.
We have to note that when we have opposite forces, one is said to be positive and the other negative and the resultant force can be found by subtraction. As such the resultant force can be obtained from;
Let the +B force be 12 N
Let the -B force be 5N
12 N - 5 N = 7 N
