The trade discount rate for the wholesaler at the net price is 0.45 or 45%.

A trade discount is a cut in the list price of products or services provided by a seller to a customer who makes frequent or significant purchases of such items. A trade discount is intended to encourage the customer to make further purchases from the supplier. The discount might change depending on the volume or regularity of purchases and is often given as a percentage of the list price. Retailers or wholesalers that purchase products from producers or suppliers to resell to consumers frequently receive trade discounts.

The discount rate is given by the following formula:

Trade Discount Rate = (List Price - Net Price) / List Price

Substituting the given values, we get:

Discount Rate = (13600 - 7480) / 13600

Discount Rate = 0.45 or 45%

Hence, the trade discount rate for the wholesaler is 0.45 or 45%.

With the discount, each dresser would cost $450.

What is the discount?

A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. It is a form of incentive that is used to encourage customers to purchase goods or services, often by making them more affordable or attractive.

To calculate the amount of discount off each item, we need to know the original price of each dresser and the percentage discount that is being offered. Let's assume that the original price of each dresser is $500, and the discount being offered is 10%.

To calculate the discount off each item, we can use the following formula:

Discount amount = Original price x Discount rate

where the discount rate is the percentage discount expressed as a decimal (e.g., 10% = 0.1).

So, for each dresser, the discount amount would be:

Discount amount = $500 x 0.1 = $50

Therefore, each dresser would be discounted by $50. This means that the new price for each dresser would be:

New price = Original price - Discount amount

New price = $500 - $50 = $450

Hence, with the discount, each dresser would cost $450.

The role of GCF, its placement and verification has been explained below. The solution has been obtained by using the concept of Greatest Common Factor.

The greatest common factor, or largest number, is the product of two or more numbers (GCF). The greatest number (factor) that separates them yields a natural number.

1. The GCF is a factor that all terms in a polynomial share.

For instance, if the polynomial has the form R * S + R * T, the GCF is R because both terms share the factor R.

2. The GCF is positioned in front of the remaining polynomials, outside of the parenthesis, once we have factored out the GCF.

R * S + R * T, given the prior example, is R (S + T).

3. By allocating the GCF to the polynomial enclosed in parenthesis, we can verify that our factoring is accurate.

Hence, the above stated is the role of GCF in factoring a polynomial.

2a. Growth

2b. r = 2.23

2c. a = 225

2d. y = 340.4025

Step-to-Step Explanation:

1.

  (a)Decay

  (b) [tex]y=a(1-r)^{x}[/tex]

       r = rate of decay, a is the initial value

       1-r=0.57 = r=1-0.57 = r = 0.43

  (c) a = 35

  (d) [tex]y=35(0.57)^{3}\\\\y=35(0.185193)\\y=6.481755[/tex]

2.

   (a) Growth

   (b)[tex]y=a(1+r)^{x} \\[/tex]

        r = rate of growth, a is the initial value

         1+r=1.23 = r=1+1.23 = r = 2.23

   (c) a = 225

   (d) [tex]y=225(1.23)^{2} \\y=225(1.5129)\\y=340.4025[/tex]

Problem 1

Set the base of the exponent equal to 1+r and solve for r.

1+r = 0.57

r = 0.57-1

r = -0.43

The result is negative, which tells us we have exponential decay. Notice that b = 0.57 fits the interval 0 < b < 1.

The rate of decay is 43%

The initial value is a = 35 since this is the first value mentioned in the equation. Plugging x = 0 into the equation will lead to y = 35.

Let's now plug in x = 3

y = 35*(0.57)^x

y = 35*(0.57)^3

y = 35*0.185193

y = 6.481755

-----------------------------

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

Problem 2

We'll follow similar steps as problem 1.

1+r = 1.23

r = 1.23-1

r = 0.23

The r value is positive, so we have growth this time. Notice that b = 1.23 fits the interval b > 1.

The growth rate is 23% since r = 0.23 converts to this.

The initial value is a = 225. Compare y = a(1+r)^x to y = 225(1.23)^x to see how the terms match up. If you want you can think of it like y = 225(1+0.23)^x. Plugging x = 0 into the equation will lead to y = 225.

Let's plug in x = 2.

y = 225*(1.23)^x

y = 225*(1.23)^2

y = 225*1.5129

y = 340.4025

Amount of money do you need to save to purchase the home is  $15,000. The total amount the bank will be loaning you is $235,000.  You can expect to pay around $1,332.29 per month.

A down payment is a payment made upfront when purchasing a large ticket item, such as a home or a car. It is a percentage of the total purchase price that the buyer pays out of their own pocket, with the remainder of the price financed through a loan.

To calculate the down payment, we need to multiply the purchase price by the percentage:

Down payment = 0.03 x $250,000 = $7,500

To calculate the closing costs, we also need to multiply the purchase price by the percentage:

Closing costs = 0.03 x $250,000 = $7,500

So the total amount of money needed to purchase the home is the sum of the down payment and the closing costs:

Total cost = $7,500 + $7,500 = $15,000

The amount the bank will be loaning you is the purchase price minus the down payment and the closing costs:

Loan amount = $250,000 - $15,000 = $235,000

To calculate the monthly payments, we need to use the formula for a fixed-rate mortgage:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ⁻¹]

where:

M = monthly payment

P = loan amount

i = monthly interest rate (5.5% / 12 = 0.0045833)

n = total number of payments (30 years x 12 months = 360)

Plugging in the numbers, we get:

M = $235,000 [ 0.0045833(1 + 0.0045833)³⁶⁰ ] / [ (1 + 0.0045833)³⁶⁰ – 1]

M ≈ $1,332.29

So you can expect to pay around $1,332.29 per month for 30 years to pay off the mortgage.

Answer: They all have the same unit rate

Step-by-step explanation:

3:1 is the unit rate if you multiply it by 2, it's 6:2. If multiplied by 3, it is 9:3. Multiplied by 4, its 12:4

Step-by-step explanation:

Since u and w are orthogonal, their dot product is 0. Thus,

u · w = 0

Using the Pythagorean Theorem,

||u - w||^2 = ||u||^2 + ||w||^2 - 2(u · w)

Since u and w are unital (i.e., their lengths are 1), we have

||u||^2 = ||w||^2 = 1

Substituting these values and u · w = 0, we get

||u - w||^2 = 1 + 1 - 0 = 2

Taking the square root of both sides, we get

||u - w|| = √2

Therefore, we have shown that if u and w are unital orthogonal vectors, then ||u - w|| = √2.

It would cost N125.00 to furnish a square room of 5m at N5.00 per square meter.

A square meter is a unit of measurement that denotes the surface area of a two-dimensional object or surface that is one metre long and one meter broad. It is frequently used to determine the dimensions of rooms, structures, and other areas as well as the surface area of land or other objects. The imperial method of measurement converts one square metre into 10.764 square feet. Science, engineering, and other fields frequently utilise the square metre, a core unit of the International System of Units (SI).

The area of the room is:

Area = 5m x 5m = 25 square meters

Then, we multiply the area by the cost per square meter:

Cost = 25 square meters x N5.00 per square meter = N125.00

The slope of a line represents the rate of change between the x and y variables, or the rise over the run. A positive slope means that the line is increasing from left to right, while a negative slope means that the line is decreasing from left to right. A slope of zero means that the line is horizontal, while an undefined slope means that the line is vertical.

A) The rate of decrease in oil reserves is 19 billion barrels per year, which can be represented as a slope of -19. The initial oil reserves are 1890 billion barrels, which is the y-intercept. Therefore, the linear equation for the total remaining oil reserves R, in terms of t (the number of years since now) is:

R = -19t + 1890

B) To find the total oil reserves 11 years from now, we can substitute t = 11 into the equation:

R = -19(11) + 1890

R = -209 + 1890

R = 1681 billion barrels

Therefore, 11 years from now, the total oil reserves will be 1681 billions of barrels.

C) If no other oil is deposited into the reserves, the reserves will be completely depleted when R = 0. We can use the linear equation to find how long it will take for the reserves to reach 0:

0 = -19t + 1890

19t = 1890

t = 99.47 years

Therefore, the world's oil reserves will be completely depleted (all used up) approximately 99.47 years from now, assuming no new reserves are discovered or added.

The single transformation that maps shape A onto shape C is a translation of 4 units to the right.

A single transformation is a mathematical operation that changes the position, orientation, or size of a geometric figure. It can be a translation, reflection, rotation, or dilation. It is a way to describe how a figure is transformed to obtain a new figure.

To map shape A onto shape C, we need to perform a sequence of transformations.

First, shape A is reflected in the line x = 2 to give shape B. This is a reflection in the vertical line passing through x = 2.

Next, shape B is reflected in the line x = 6 to give shape C. This is a reflection in the vertical line passing through x = 6.

To find the single transformation that maps shape A onto shape C, we can combine these two reflections into a single transformation.

The composition of two reflections in vertical lines is a translation.

In this case, the distance between the vertical lines x = 2 and x = 6 is 4 units. Since shape A is reflected in the first vertical line and shape C is reflected in the second vertical line, the movement is from the first line to the second line, which is to the right.
