Compute the present value of $4800 paid in two years using the following discount rates: 8% in the first year and 7% in the second year.

Answers

Answer:

Value 2 years from today 4%

Value one year from today5%

Present Value 6%

Step-by-step explanation:

The present value of $4800paid in two years using the following discount rates: 8% in the first year and 7% in the second year will be $4106.88.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given the principle amount of $4800

Now, 8% of 4800 ⇒ $384

So amount = 4800 - 384 = $4416

Now, 7% of 4416 ⇒ $309.12

So amount = 4416 - 309.12 = $4106.88

Hence "The present value of $4800paid in two years at a given discount will be $4106.88".

For a standard hedge garden, Fran charges a flat rate of $25 then an additional $135 per hedge planted. One of Fran’s neighbor companies, owned by Shirley, charges a flat rate of $65 and an additional fee of $150 per hedge.

f(h) = 25 + 135h
s(h) = 65 + 150h

How much will a customer save by choosing Fran’s company to plant 8 hedges rather than choosing Shirley’s? Explain how you know your answer.

Answers

In choosing Fran's company over Shirley's company, the customer saves $160

What is Algebra?

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.)

As per the given details:

Fran charges f(h) = 25 +135h

Shirley charges s(h) = 65 + 150h

h = number of hedges

Cost in Fran's company for 8 hedges = 25 + 135(8)

= $1105

Cost in Shirley's company for 8 hedges = 65 + 150(8)

= $1265

Cost saved by the customer in choosing Fran's company:

Cost in Shirley's company - Cost in Fran's company

=  $1265 - $1105

=  $160

A customer saves $160 in choosing Fran's company over Shirley's company.

If every 2 cm on a scale drawing is equal to 7 feet in real life, which lines on the drawing would be greater than 21 feet in real life? Select all that apply. A) 7 cm B) 5 cm C) 9 cm D) 12 cm

Answers

The correct answers are A) 7cm, C) 9cm and D) 12cm

Define the Conversion of units?

The process of changing a given quantity that is expressed in one unit of measurement to another unit of measurement that is equivalent in value is referred to as conversion of units.

If every 2 cm on a scale drawing is equal to 7 feet in real life, then we can use proportions to find out which lines on the drawing would be greater than 21 feet in real life.

Let x be the length of a line on the scale drawing in centimeters. Then, we can set up the following proportion:

⇒  \(\frac{2cm}{7 feet} = \frac{x cm }{yfeet}\)

where y is the length of the line in real life. Solving for y, we get:

⇒  \(y = \frac{7 feet} {2cm} *x\)  

⇒  \(y = 3.5 x feet\)

If we put x = 2cm (given) then, y = 7 feet

For y = 21 feet, the value of x = 6cm.

Therefore, any line on the scale drawing that is greater than 6cm in length corresponds to a length greater than 21 feet in real life.

So, the lines on the drawing that are greater than 21 feet in real life are:

A) 7cm, C) 9cm, D) 12cm

Therefore, the correct answers are A) 7cm, C) 9cm and D) 12cm

Sketch and label a net of the right triangular prism. Each square on the grid represents1 square centimeter.

Answers

The total surface area of the prism is determined as  216 cm².

What is the surface area of the prism?

The surface area of the prism is calculated by applying the following formula.

The area of the two triangular faces is calculated as follows;

Area of the two triangles = 2 (¹/₂ x base x height )

Area of the two triangles = 2 (¹/₂ x 6 cm x 4 cm )

Area of the two triangles = 24 cm²

The area of rectangular faces is calculated as follows;

A = ( 5 cm x 12 cm ) + (5 cm x 12 cm ) + ( 6 cm x 12 cm )

A = 192 cm²

The total surface area of the prism is calculated as follows;

Area = 24 cm² + 192 cm²

Area = 216 cm²

You buy halibut at $25 per pound. One portion of seared halibut requires 6 ounces of halibut. How much does the halibut for one portion cost?

Answers

Answer:

6 ounces is 3/8 pounds. 3/8 * 25 = $9.38

One portion of halibut will cost $9.38

Let understand that 1 pound = 16 ounce

According to the question, 1 pound of halibut cost is at $25

In the same word, 16 ounce of halibut cost also cost $25 because "1 pound = 16 ounce"

It is now stated that one portion of seared halibut requires 6 ounces of halibut.

Now, 6 ounce of halibut will cost: \(($ 25/16) * 6\) = $9.375 ≅ $9.38

Since \(x\) is approaching 1 from the left/below, we take the part of \(f(x)\) that is defined over \(x<1\), for which we have

\(f(x) = \dfrac{x-1}{\sqrt{x-1}}\)

Since \(x\neq1\), we can simplify this to

\(f(x) = \dfrac{x-1}{(x-1)^{1/2}} = (x-1)^{1/2} = \sqrt{x-1}\)

and this is continuous at \(x=1\), so we can evaluate the limit by directly substituting \(x\).

To summarize:

\(\displaystyle \lim_{x\to1^-} f(x) = \lim_{x\to1} \frac{x-1}{\sqrt{x-1}} = \lim_{x\to1} \sqrt{x-1} = \sqrt{1-1} = \boxed{0}\)

The 13-year $1,000 par bonds of Vail Inc. pay 13 percent interest. The market's required yield to maturity on a comparable-risk bond is 14 percent. The current market price for the bond is $870.
a. Determine the yield to maturity.

Answers

The current market price for the bond is $870 the yield to maturity is 14.13%

How is yield to maturity calculated?

The approximate yield to maturity of this bond is 11.25%, which is above the annual coupon rate of 10% by 1.25%. You can then use this value as the rate (r) in the following formula: C = future cash flows/coupon payments. r = discount rate (the yield to maturity)

knowing that:

Face value (par value) of the bond (F) = $1,000Annual coupon rate (C) = 13% of the face value = 0.13 * $1,000 = $130Years to maturity (n) = 13 yearsCurrent market price of the bond (P) = $870

the formula is:

\(P = (C / (1 + r))^1 + (C / (1 + r))^2 + ... + (C + F) / (1 + r)^n\)

Putting the values:

\($870 = (130 / (1 + r))^1 + (130 / (1 + r))^2 + ... + (130 + 1,000) / (1 + r)^13\)

Using the math we find that the percentage is  approximately 14.13%;

A manufacturer has 576 square inches of material available to construct the 6 faces of a carton, which will be in the shape of a rectangular prism. To maximize the volume, the carton will have dimensions such that the length and width are each twice the height.

Answers

To maximize the volume, of the rectangular prism, the carton should have dimensions of approximately 10.74 inches (length), 10.74 inches (width), and 5.37 inches (height).

What is the dimension required to maximize the volume of the box?

Assuming the height of the rectangular prism is h inches.

According to the given information, the length and width of the prism will be twice the height, which means the length is 2h inches and the width is also 2h inches.

The total surface area of the rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

Substituting the values, we have:

576 = 2(2h)(2h) + 2(2h)(h) + 2(2h)(h)

576 = 8h² + 4h² + 4h²

576 = 16h² + 4h²

576 = 20²

h² = 576/20

h² = 28.8

h = √28.8

h = 5.37

The height of the prism is approximately 5.37 inches.

The length and width will be twice the height, so the length is approximately 2 * 5.37 = 10.74 inches, and the width is also approximately 2 * 5.37 = 10.74 inches.
