Rachael purchased a five year $4,750 bond below par value for $3,940 with a coupon of 2.9%. What was her yield?

Mashutka [201]

Yield is given by:
current yield=(annual cash flow)/(market price)
annual cashflow(coupon)= 2.9/100×4750=137.75
market price of the bond= $3940
thus the yield will be given by:
137.75/3940
=0.03496

A lake is 200 feet wide. Two boats start to move towards one another from opposite shores. In one minute, the first boat goes 40

NARA [144]

Answer:

I use faction

Step-by-step explanation:

The first boat.

$\frac{40 feet}{60 seconds}$ ÷ 10 = $\frac{4 feet}{6 seconds}$

$\frac{4 feet}{6 seconds}$ ÷ 2 = $\frac{2 feet}{3 seconds}$

The first boat move $\frac{2 feet}{3 seconds}$

The second one do the same

$\frac{30 feet}{60 seconds}$ ÷ 10 = $\frac{3 feet}{6 seconds}$

$\frac{3 feet}{6 seconds}$ ÷ 2 = $\frac{1.5 feet}{3 seconds}$

That is the speed of each boat.

The first boat need 50 minutes to get to the other side

2000 ÷ 2 =1000

1000 x 3 = 3000

3000 ÷ 60 = 50

The second boat need 66.6666666667 minutes to get to the other side

200 ÷1.5 = 1333.33333333

1333.33333333 x 3 = 4000

4000 ÷ 60 = 66.6666666667

When graphing the inequality. 2 - 8> -20 is it open or closed dot, and is it shaded to the left or the right?

Goryan [66]

Answer:

I assume you know the 4 inequalites:

The 4 Inequalities

Symbol Words Example

> greater than x+3 > 2

< less than 7x < 28

≥ greater than or equal to 5 ≥ x−1

≤ less than or equal to 2y+1 ≤ 7

The "open circle" represents less than or greater than, and the "closed circle" represents greater than or equal to or less than or equal to.

Hope it helps! Have a great day! :) let me know if it helped

Using the letters in the word INNOVATIVE, find the number of permutations that can be formed using 4 letters at a time. Show you

lyudmila [28]

Answer: 1) 5040 and 2) 165

Step-by-step explanation:

1) Here total number of letters = 10

The number of permutations that can be formed using 4 letters at a time

= P (10, 4)

= $10_P_4$

= $\frac{10!}{(10-4)!}$

= $\frac{10!}{6!}$

= $\frac{10\times 9\times 8\times 7\times 6!}{6!}$

= 10 × 9 × 8 × 7

= 5040

2) Here the total number of machine = 11

The different combinations of machines can Geoff choose from to use

= $11_C_3$

= $\frac{11!}{(11-3)!3!}$

= $\frac{11!}{8!3!}$

= $\frac{11\times 10\times 9\times 8!}{8!\times 6}$

= 11 × 5 × 3

= 165
