A wealthy man just died and left his pet dogs the following estate: $20,000 per year for the next 11 years with the first cash flow today. at a discount rate of 4. 2%, what is the doggy estate worth in today's dollars?

Answers

The concept of present value lets us know that the doggy estate worth in today's dollars is $180614.80

What is the present value of the doggy estate worth?

The concept of present value is significant because it enables investors to determine whether the amount they pay for an investment is reasonable. The present value of a future cash flow defines how much it is worth in today's value.

From the given information:

The annual cashflow C = $20,000Interest rate (i) = 4.2% = 0.042Number of period (n) = 11

Thus, the present value of the doggy estate can be calculated by using the formula;
[tex]\mathbf{PV = C \times \Big [ \dfrac{1 - \dfrac{1}{(1+i)^n}}{i}\Big] \times (1+i)}[/tex]

[tex]\mathbf{PV = 20000 \times \Big [ \dfrac{1 - \dfrac{1}{(1+0.042)^{11}}}{0.042}\Big] \times (1+0.042)}[/tex]

PV = $180614.80

Houston homes has outstanding debt of $78 that is due in one year. given the financial distress costs, debtholders will receive only $62 if the firm does well and $24 if it does poorly. the probability that the firm will do well is 75 percent and the probability that it will do poorly is 25 percent. assuming a discount rate of 9.6 percent, what is the current value of the debt?

Answers

The current value of the debt based on the probability given about Houston homes is $47.90.

How to calculate the current value of debt?

From the information given, the expected payment to debt holders will be:

= ($62 × 75%) + ($24 × 25%)

= $46.50 + $6

= $52.50

The current value of the debt will be:

= 52.50 / (1 + 9.6%)

Answers

The sequence of transformation is:

a dilation with center (0, 0), a scale factor 2, and a reflection across the y-axis

How to determine the sequence of transformation?

The coordinates are given as:

p = (-1, 1)

q = (-2, 3)

r = (-2.5, 1)

p' = (2 , 2)

q' = (4, 6)

r' = (5, 2)

Start by reflecting the triangle pqr across the y-axis.

The transformation rule is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

p = (1, 1)

q = (2, 3)

r = (2.5, 1)

Dilate the resulting by a scale factor of 2 with the center of (0, 0)

The transformation rule is:

(x,y) = 2(x,y)

So, we have:

p' = (2 , 2)

q' = (4, 6)

r' = (5, 2)

Hence, the sequence of transformation is:

a dilation with center (0, 0), a scale factor 2, and a reflection across the y-axis
