Answer:

3/7 meters

Step-by-step explanation:

\( \sqrt{ \frac{9}{49} } = \frac{ \sqrt{9} }{ \sqrt{49} } = \frac{3}{7} \)

The yield to maturity of a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons, if the =bond is currently trading for a price of $884, is 6.23%. Thus, option a and option b is correct

Yield to maturity (YTM) is the anticipated overall return on a bond if it is held until maturity, considering all interest payments. To calculate YTM, you need to know the bond's price, coupon rate, face value, and the number of years until maturity.

The formula for calculating YTM is as follows:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

Where:

C = Interest payment

F = Face value

P = Market price

n = Number of coupon payments

Given that the bond has a coupon rate of 5.2%, a face value of $1000, a maturity of ten years, semi-annual coupon payments, and is currently trading at a price of $884, we can calculate the yield to maturity.

First, let's calculate the semi-annual coupon payment:

Semi-annual coupon rate = 5.2% / 2 = 2.6%

Face value = $1000

Market price = $884

Number of years remaining until maturity = 10 years

Number of semi-annual coupon payments = 2 x 10 = 20

Semi-annual coupon payment = Semi-annual coupon rate x Face value

Semi-annual coupon payment = 2.6% x $1000 = $26

Now, we can calculate the yield to maturity using the formula:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

YTM = (2 x $26 + ($1000-$884)/20) / (($1000+$884)/2) x 100

YTM = 6.23%

Therefore, If a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons is now selling at $884, the yield to maturity is 6.23%.

Answer:

x=-1

Step-by-step explanation:

5x=-5

\(x=\frac{-5}{5}=-1\)

Answer:

Step-by-step explanation:

a) i) Solving x = 2, b) Cancelling out the common factors: -(x - 2)/(x + 2), c) Therefore, the solutions to the equation x^2 + 14x - 51 = 0 are x = 3 and x = -17.

(a)

(i) To solve the equation 12x + 4 = 50 - 11x, we can start by combining like terms:

12x + 11x = 50 - 4

23x = 46

To isolate x, we divide both sides of the equation by 23:

x = 46/23

Simplifying further, we have:

x = 2

(ii) For the equation 4 - 5/(6x - 3) = 3/7 + 3x, we can begin by multiplying both sides by the common denominator of 7(6x - 3):

7(6x - 3)(4 - 5/(6x - 3)) = 7(6x - 3)(3/7 + 3x)

Simplifying:

28(6x - 3) - 5 = 3(6x - 3) + 21x

Distributing and combining like terms:

168x - 84 - 5 = 18x - 9 + 21x

Simplifying further:

168x - 89 = 39x - 9

Bringing like terms to one side:

168x - 39x = -9 + 89

129x = 80

Dividing both sides by 129:

x = 80/129

(b) To simplify the expression (x^2 - 4x + 4)/(4 - x^2), we can factor both the numerator and denominator:

(x - 2)^2/(-(x - 2)(x + 2))

Cancelling out the common factors:

-(x - 2)/(x + 2)

(c) To solve the equation x^2 + 14x - 51 = 0 by completing the square, we start by moving the constant term to the other side:

x^2 + 14x = 51

Next, we take half of the coefficient of x (which is 14), square it, and add it to both sides:

x^2 + 14x + (14/2)^2 = 51 + (14/2)^2

Simplifying:

x^2 + 14x + 49 = 51 + 49

x^2 + 14x + 49 = 100

Now, we can rewrite the left side as a perfect square:

(x + 7)^2 = 100

Taking the square root of both sides:

x + 7 = ±√100

x + 7 = ±10

Solving for x:

x = -7 ± 10

This gives two solutions:

x = -7 + 10 = 3

x = -7 - 10 = -17

Therefore, the solutions to the equation x^2 + 14x - 51 = 0 are x = 3 and x = -17.

(ii) The solution to the equation \(4 - \frac{1}{5} (6x - 3) = \frac{7}{3} + 3x\) is x = 34/63

(b) The simplified expression is \(\frac{-(2 + x)}{(x + 2)}\)

(c) By using completing the square method, the solutions are x = -3 or x = -17

(i) First of all, we would rearrange the equation by collecting like terms in order to determine the solution as follows;

12x + 4 = 50 − 11x

12x + 11x = 50 - 4

23x = 46

x = 46/23

x = 2.

(ii) \(4 - \frac{1}{5} (6x - 3) = \frac{7}{3} + 3x\)

First of all, we would rearrange the equation as follows;

4 - 1/5(6x - 3) + 3/5 - 7/3 - 3x = 0

-1/5(6x - 3) - 7/3 - 3x  + 4 = 0

(-18x + 9 - 45x + 25)15 = 0

-63x + 34 = 0

63x = 34

x = 34/63

Part b.

\(\frac{4 - x^2}{x^{2} -4x+4}\)

4 - x² = (2 + x)(2 - x)

(2 + x)(2 - x) = -(2 + x)(x - 2)

x² - 4x + 4 = (x - 2)(x - 2)

\(\frac{-(2 + x)(x - 2)}{(x + 2)(x - 2)}\\\\\frac{-(2 + x)}{(x + 2)}\)

Part c.

In order to complete the square, we would re-write the quadratic equation and add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² + 14x - 51 = 0

x² + 14x = 51

x² + 14x + (14/2)² = 51 + (14/2)²

x² + 14x + 49 = 51 + 49

x² + 14x + 49 = 100

(x + 7)² = 100

x + 7 = ±√100

x = -7 ± 10

x = -3 or x = -17

To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.

A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:

Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.

Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.

For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.

In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.

Since, sin x= cos (90 - x)

So, We get;

⇒ sin (3x - 7) = cos (x + 1)

⇒ cos (90 - (3x - 7)) = cos (x + 1)

⇒ 90 - (3x - 7) =  (x + 1)

The formula relating the monetary multiplier and the reserve ratio shows that as the monetary multiplier increases, the reserve ratio decreases. If the monetary multiplier is 6, the reserve ratio must be 0.167.

To determine the reserve ratio given the monetary multiplier, we can use the formula:

Monetary Multiplier = 1 / Reserve Ratio

Given that the monetary multiplier is 6, we can substitute this value into the formula:

6 = 1 / Reserve Ratio

To isolate the reserve ratio, we can take the reciprocal of both sides of the equation:

1 / 6 = 1 / (1 / Reserve Ratio)

1 / 6 = Reserve Ratio

Therefore, the reserve ratio must be 1/6 or approximately 0.167.

The probability of rolling a six, and then getting heads upon tossing the coin is 1/12.

The probability of rolling a six on a die is one-sixth, while the likelihood of landing on heads on a coin flip is one-half. To find the probability of both events happening together, we need to multiply the probabilities.

P(rolling a six and getting heads) = P(rolling a six) × P(getting heads)

P(rolling a six and getting heads) = 1/6 × 1/2

P(rolling a six and getting heads) = 1/12

Therefore, the probability of rolling a six and getting heads upon tossing the coin is 1/12.

As per the concept of probability, the number of parts should they order under their regular shipment for the next six months is approximately 18.

In this scenario, the demand rate is given as a Poisson distribution with a mean of 6.5. The holding cost is $5 per part, and the unit cost under regular, semiannual shipment is $32 per part, while the cost of an emergency shipment is $50 per part.

Since we know that orders are placed semiannually, we need to find the order quantity that will last for six months. To do this, we can divide the total annual demand by 2. Therefore, the annual demand for part 1aa-66 is 6.5 x 2 = 13.

Now, we can use the EOQ formula to find the optimal order quantity:

EOQ = √(2DS/H)

Where D is the demand rate, S is the ordering cost, and H is the holding cost.

Plugging in the values, we get:

EOQ = √(2 x 13 x $32 / $5) = √332.8 ≈ 18.23

The end behavior of the function f(x) is: continues downward to the left and upward to the right.

Consider the function,

f(x) = (x + 1)(x - 2)(x + 3)

The zeros are when f(x) = 0

f(x) = 0

(x + 1)(x - 2)(x + 3) = 0

Therefore,

(x + 1) = 0

So, x = -1

(x - 2) = 0

So, x = 2

(x + 3) = 0

So, x = -3

Therefore, the zeros are at x = - 1, x = 2 and x = - 3

To expand the function, we multiply the brackets:

f(x) = (x + 1)(x - 2)(x + 3)

f(x) = ( x + 1 )( x² + x - 6 )

f(x) = x³ + 2x² - 5x - 6

As the leading coefficient (the coefficient of x³) is positive, the end behavior of the function is:

f(x ) → + ∞, as x → + ∞
