Builtrite bonds have the following: 5 1/2% coupon, 10 years until maturity, $1000 par and are currently selling at $1044. If you purchase this bond, what would be your AYTM?

Answers

The annual yield to maturity (AYTM) of the Builtrite bonds is at 5.5% for 10 years with a $1,000 par value and the current price of $1,044 is A. 4.9%.

What is the annual yield to maturity (AYTM)?

The annual yield to maturity (AYTM) is the total return expected from a bond if the bond is held till maturity.

The AYTM rate is the rate at which all future expected cash flows are discounted to find out the current value or the price of the bond.

We can use the following Yield to Maturity formula to calculate the AYTM.

Yield to Maturity = [Annual Interest + {(FV-Price)/Maturity}] / [(FV+Price)/2]

Data and Calculations:

Annual Interest = Annual Interest Payout by the Bond = $55 ($1,000 x 5.5%)

FV = Face Value of the Bond = $1,000

Price = Current Market Price of the Bond = $1,044

Maturity = Time to Maturity = 10 years

= {$55 + ($1,000 - $1,044)/10} / {($1,000 + $1,044)/2}

= $55 + -4.4 / 1,022

= 50.6/1,022

= 4.95%

We can also use an online finance calculator to check the calculated value above as follows:

N (# of periods) = 10

I/Y (Interest per year) = 4.95%

PMT (Periodic Payment) = $55 ($1,000 x 5.5%)

FV (Future Value) = $1,000

Results:

PV = $1,044

Sum of all periodic payments = $550 ($55 x 10)

Total Interest $503.44

Answer Options:

A. 4.9%

B. 5.1%

C. 5.3%

D. 5.5%

Thus, the annual yield to maturity (AYTM) of the Builtrite bonds is at 5.5% for 10 years with a $1,000 par value and the current price of $1,044 is A. 4.9%.

Answers

They had 56 lives in total

Explanation: if there were thirteen friends to begin with and six quit that would leave them with 7 friends. If those seven remaining friends each had 8 lives, you multiply those 7 friends by 8 lives which would get 56.

If all thirteen friends were still in the game then they would have 104 lives all together.

62–√ cm

Answers

Answer:

The answer is 12 cm.

Step-by-step explanation:

Verified by correct test results.

The length of the hypotenuse of the given right triangle would be 12cm.

What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.The sum of the angles of the triangle is equal to 180 degrees.∠A + ∠B + ∠C = 180°

Given is that the length of the shorter leg of a 30-60-90 Special Right Triangle is 6 cm long.

The base length is the shortest distance of the right - angled triangle. We can find the hypotenuse using the cosine function as -

cos(60) = b/h

h ={b/cos(60)}

h = 6/(1/2)

h = 6 x 2

h = 12 cm

Therefore, the length of the hypotenuse of the given right triangle would be 12cm.

NO LINKS!! Explain your answer (show the support by showing the changes in x and y on your table). If the relationship is linear, inverse, or exponential, write the equation.
#7 and #8​

Answers

Answer:

  7. inverse relationship; equation: y = 16/x

  8. no relationship; no equation

Step-by-step explanation:

The attachment shows the support for the conclusions. The relationship can be chosen from those offered by looking at differences, ratios, or products of y-values for sequential x-values.

linear: constant differencesexponential: constant ratiosinverse: constant products

__

7.

In the first problem, we note that the relationship between y-values varies inversely as the relationship between x-values: when x goes up by a factor of (n+1)/n, the value of y goes down by its inverse factor: n/(n+1). That same relationship is observed by noting that the product of x and y is a constant, 16.

 relationship: inverse

  y = 16/x

__

8.

As we looked at the table, we thought this might be an exponential function. Each y-value seemed to be twice the one before—until we got to x=5. As x went from 4 to 5, the y-value increased by a factor of 16, not 2. This means there is no simple relationship between x and y, and no simple equation that will describe the sequence of y-values.

Answer:

Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.

Inverse relationship:  the value of one variable decreases as the value of the other variable increases.

Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)

Question 7

As the x-value increases (by one unit), the y-value decreases.

Therefore, this is an inverse relationship.

The y-values are calculated by dividing 16 by the x-value.

[tex]\sf y=\dfrac{16}{x}[/tex]

Question 8

As the x-value increases, the y-value increases.  

The y-value increases by a factor of 2 for each x-value increase of 1 unit from 1 ≤ x ≤ 4 and 5 ≤ x ≤ 6.

[tex]\sf y=2^x \ for \ 1\leq x\leq 4[/tex]

[tex]\sf y=2^{(x+3)} \ for \ 5\leq x \leq 6[/tex]

These are separate exponential relations for restricted domains.

So there doesn't appear to be one relationship for a non-restricted domain.
