What is the solution of log(3x − 2)125 = 3?

Reil [10]

$log_{3x - 2}125 = 3 \\ (3x - 2)^3 = 125 \\ \sqrt[3]{(3x - 2)^3} = \sqrt[3]{125} \\ 3x - 2 = 5 \\ 3x = 5 + 2 \\ 3x = 7 \\ x = 7/3$

Answer:

The value of PR is 21 ft.

Step-by-step explanation:

3(PQ + QT + TP) = PR + RS + SP
PQ = 7 ft.
QT = 4 ft
RS = 12 ft.

3(PQ + QT + TP) = PR + RS + SP
=> 3(7 + 4 + TP) = PR + 12 + SP
=> 21 + 12 + 3TP = PR + 12 + SP
=> 21 + 3TP = PR + SP
=> 21 + SP = PR + SP [3TP = SP]
=> 21 = PR

Hence, <u>the value of PR is 21 ft.</u>

Hoped this helped.

Today, you want to sell a $1,000 face value zero coupon bond you currently own. The bond matures in 3.5 years. How much will you

Agata [3.3K]

The amount I would receive for the bond when I sell it at the yield to maturity is $810.41.

<h3>How much would I receive for the bond?</h3>

In order to determine the amount I would receive for the bond, the present value of the bond has to be determined. Present value is the discounted cash flow.

Present value = $10000 / (1.0619)^3.5 = $810.41
