Answer:

6 ft

Step-by-step explanation:

Let the width = w

Then the length = 4w - 3

perimeter = 2(length + width)

perimeter = 2(4w - 3 + w)

perimeter = 2(5w - 3)

perimeter = 10w - 6 = 54

10w - 6 = 54

10w = 60

w = 6

Answer: The width is 6 ft

A company issues 7% bonds with a par value of $200,000 at par on January 1. The market rate on the date of issuance was 6%. The

Step2247 [10]

Answer:

The cash paid to the bondholder on July 1 is Z = $7000

Step-by-step explanation:

From the question we are told that

The percentage bond issued by the company is $n = 7$ %

The par value of the bond is $V =$ $200,000

The market rate is $r = 6$ %

So we are told that the bonds pay interest semiannually on January 1 and July

So the cash paid to the bondholder on July 1 is mathematically evaluated as

Z = $V * \frac{7}{100} * \frac{1}{2}$

substituting value

Z = $200000 * \frac{7}{100} * \frac{1}{2}$

Z = $7000

Ad libitum [116K]

Answer:

C.

Step-by-step explanation:

$\cos x+\sqrt{2}=-\cos x \\ 2\cos x = -\sqrt 2 \\ \cos x = -\dfrac{\sqrt 2}{2}\\ \\ \Rightarrow x = \pm \arccos\Big(-\dfrac{\sqrt 2}{2}\Big)+2k\pi,\quad x\in \mathbb{Z}\\ \Rightarrow x =\pm\dfrac{3\pi}{4}+2k\pi\\ \\ \\k = -1 \Rightarrow x < 0\\\\ k=0 \Rightarrow x 2\pi$

Answer:

MK = 14

Step-by-step explanation:

MK = ML + LK , substitute values

4x - 2 = 8 + x + 2

4x - 2 = x + 10 ( subtract x from both sides )

3x - 2 = 10 ( add 2 to both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Thus

MK = 4x - 2 = 4(4) - 2 = 16 - 2 = 14
