King of Diamonds Industries has bonds on the market making annual payments, with 14 years to maturity, and selling for R1 482,01. At this price, the bonds yield 7%. What is the coupon rate?

Answers

The coupon rate of the bonds by King of Diamonds Industries would be 7 %.

How to find the coupon rate ?

The formula for the bond price shows the coupon payment and so can be used to find the coupon rate:

= (Coupon payment x ( 1 - ( 1 + r ) ^ ( - number of years till maturity ) ) ) / r + Face value / (1 + rate )^ number of years

1,482.01 = (C x (1 - (1 + 0.07 )^ (- 14) ) ) / 0.07 + F / (1 + 0.07 ) ^ 14

103.7407 - 0.07 x (F / (1 + 0.07) ^14 ) = C x (1 - ( 1 + 0.07) ^ ( - 14) )

Using a calculator, C is $ 70.

This means that the coupon rate is:

= 70 / 1, 000

= 7 %

Answer: m∠BAC = 72°

. m∠BCD = 108°

I took the test :)

Step-by-step explanation:

The measure of angles from the given diagram is

∠BOD=108°

∠BAC=72°

Given :

From the given diagram , the angles

$<B=4x-16\\<BCA=5x+7$

Given triangle is an isosceles triangle

∠A=∠BCA

$<A = 5x+7$

sum of interior angles in a triangle is 180 degrees

$<A+<B+<BCA= 180\\5x+7+4x-16+5x+7=180\\\\14x+7-16+7=180\\14x-2=180\\14x=182\\\frac{14x}{14}=\frac{182}{14}\\x=13$

substitute the value of x and find out the remaining angles

$<B=4x-16\\\\<B=4(13)-16=36\\<BCA=5(13)+7=72\\\\<A= 72$

Angle BCA and angle BCD are linear pair of angles

$<BCA =72\\<BCD= 180-<BCA\\<BCD=180-72\\<BCD=108$

<BAC= 72 degrees

On a number line, the coordinates of X, Y, Z, and W are - 6, -2, 4, and 8, respectively. Find the lengths of the two segments below. Then tell whether they are congruent
XY and ZW

Answers

If the coordinates of X, Y, Z, and W on a number line are - 6, -2, 4, and 8, respectively, then the lengths of the segment XY is 4 and that of the segment ZW is also 4, and hence, these two segments (XY and YZ) are indeed Congruent in nature.

To increase the understandability of this question, we will go ahead a visual representation of the number line based on the condition mentioned in the question statement, attached hereby as "Number Line (-10 to 10)".

As per the figure, we can clearly see that the line segment XY begins at (-6) on the number line and ends at (-2), i.e., Length of XY is:

[(-2) - (-6)] = 4.

Similarly, we can also see that the line segment ZW begins at (4) on the number line and ends at (8), i.e., Length of ZW is:

(8 - 4) = 4.

Also, since the lengths of both XY and ZW are same, i.e., 4 Units, they are congruent in nature.

Number Line: In elementary mathematics, a number line is a picture of a graduated straight line, with real numbers, (generally integers, both positive and negative) at equal intervals on it.Congruent Lines: Two line segments of equal lengths are known to be congruent.

How are the two angles related?

Answers

The two angles are related in that they are supplementary angles

Supplementary angles would add tuo to 180 degrees according to the angle Theorem.

Adding the two given angles :

52+128 = 180

These angles are supplementary

The angles aren't vertical in that , vertical angles should have the same vertex. Complementary angles on the other hand add to 90 degrees. While the angles doesn't share the same side, hence, they aren't adjacent.

A 50 foot rope is stretched tight from the roof of a building to a spot 20 feet from the base of the
building. How tall is the building? Round your answer to TWO decimal places.

Answers

47.17 feet is the height of the building.

We can use the Pythagorean theorem to solve the problem:

Let h be the height of the building.

Then we have a right triangle with legs 20 and h, and a hypotenuse 50.

Using the Pythagorean theorem, we have:

$50^2 = 20^2 + h^2$

Simplifying and solving for h, we get:

$h = \sqrt{(50^2 - 20^2)$

h ≈ 47.17 feet (rounded to two decimal places)

Therefore, the height of the building is approximately 47.17 feet.

A rectangle with base b and height h has an area of 235 square-inches. Express the perimeter of the rectangle as a function of its base

Answers

The perimeter of the rectangle as a function of its base is P = 2(b + 235/b)

What are perimeters?

The perimeter of a shape is the sum of the side lengths of the shape For all regular quadrilaterals, you add up the side lengths to determine the area

How to express the perimeter of the rectangle as a function of its base?

The given parameters are

Area = 235 sqare inches

The area of a rectangle is calculated using

Area = Base * Height

Note that the area of a shape is the amount of space on the shape

Recall that the area of a rectangle is calculated using

Area = Base * Height

Rewrite the above equation as

A = bh

So, we have

bh = 235

Make h the subject of the formula

h = 235/b

The perimeter of the rectangle is

P = 2(b + h)

So, we have

P = 2(b + 235/b)

Hence, the perimeter of the rectangle as a function of its base is P = 2(b + 235/b)
