To find the area and perimeter of a rhombus, you can follow these steps:

1. Find the length of one side of the rhombus.

2. Use the length of one side to find the length of the diagonals. The diagonals of a rhombus are perpendicular bisectors of each other, which means that they intersect at a 90-degree angle, and each diagonal cuts the rhombus into two congruent right triangles. The length of each diagonal can be found using the Pythagorean theorem: diagonal^2 = (side/2)^2 + (side/2)^2.

3. Once you have found the length of the diagonals, you can use them to calculate the area of the rhombus. The area of a rhombus is equal to half the product of the length of the diagonals: area = (diagonal1 x diagonal2) / 2.

4. To find the perimeter of the rhombus, you simply add up the lengths of all four sides: perimeter = 4 x side.

In summary, the steps to find the area and perimeter of a rhombus are:

1. Find the length of one side of the rhombus.

2. Use the length of one side to find the length of the diagonals.

3. Use the diagonals to calculate the area of the rhombus: area = (diagonal1 x diagonal2) / 2.

4. Add up the lengths of all four sides to find the perimeter: perimeter = 4 x side.

If you were to buy one of each bond today, you would have to spend b. ABC $1104.75 and XYZ $1100.50.

The following algorithm must be used to determine a bond's price:

[tex]Bond\ price=(\frac{coupon\ payment}{(1+yield)^{time}} )+(\frac{coupon\ payment}{(1+yield)^{time+1}} )+...+(\frac{coupon\ payment+face\ value}{(1+yield)^{Time+n}} )[/tex]

Where:

dividend Payment: The bond's yearly dividend payment (in dollars)

Yield: The bond's yield to expiration (as a decimal)

Time: the interval between the issuance of each coupon and the receipt of its monetary value. (in years)

Face worth: The bond's face worth (in dollars)

The price of each bond can be determined as follows using the data in the table:

a. For bond ABC:

Coupon Payment = $7.50 (7.5% of $1000 face value)

Yield = 3.04% (convert 3.04 to a decimal)

Time = 0.5 years (since the bond's maturity date is July 15 and today marks the midway point between those dates)

Face Value = $1000

[tex]Bond\ price=(\frac{7.5}{(1+0.0304)^{0.5}} )+(\frac{7.5}{(1+0.0304)^{1.5}} )+(\frac{1000}{(1+0.0304)^{2}} )[/tex]

= 7.356 + 7.235 + 925.984

= $940.575

Since we are purchasing one bond and the face value is $1,000, we split this amount by 10 to get the price for one bond:

Price for one bond ABC = $940.575 / 10 = $94.058

b. For bond XYZ:

Coupon Payment = $84 (8.4% of $1000 face value)

Yield = 1.7% (convert 1.7 to a decimal)

Time = 0.5 years

Face Value = $1000

[tex]Bond\ Price = (84 / (1 + 0.017)^{0.5}) + (84 / (1 + 0.017)^{1.5}) + (1000 / (1 + 0.017)^2)[/tex]

= 83.379 + 81.838 + 968.661

= $1133.878

Since the face value of a bond is $1,000 and we are only purchasing one, we split this amount by 10 to get the price for one bond:

Price for one bond XYZ = $1133.878 / 10 = $113.388

Therefore, the correct answer is:b. ABC: $1104.75 XYZ: $1100.50

Answer:

Step-by-step explanation:

Bold = $8 or more per week,    Underlined = less than 8 per week

$5 = 1 person

$0 = 3 people

$10 = 2 people

$1 = 1 person

$8 = 2 people

The total amount of people = 1+3+2+1+2 = 9

The total amount of people who earn less than $8/week = 1+3+1 = 5 people

The total amount of people who earn $8 or more/week = 2+2 = 4 people

Conclusion, 5/9 total people earned less than $8/week

4/9 people earn $8 or more/week

Mistake there were less than half people who earned $8 or more per week unlike Pete stated

Correction; more than half of Pete's friends earn less than 8 dollars per week

Answer:

Step-by-step explanation:

(a) We can use the standard normal distribution to solve this problem. We first need to standardize the distribution by using the formula:

Z = (X - μ) / σ

where X is the transaction time, μ is the mean, σ is the standard deviation, and Z is the standard normal variable.

For 5 customers to finish the transaction within 20 seconds, we need to find the probability that 5 out of 6 customers have a transaction time less than or equal to 20 seconds. We can use the binomial distribution to find this probability:

P(X = 5) = 6C5 * (0.5)^5 * (0.5)^1 = 0.2344

where 6C5 is the number of ways to choose 5 customers out of 6.

(b) After the network upgrade, the transaction time will be reduced by 15%, so the new mean and standard deviation are:

μ' = 0.85 * μ = 17 seconds

σ' = 0.85 * σ = 4.25 seconds

(c) To find the 97th percentile of Y, we need to find the value of t such that P(Y ≤ t) = 0.97. Since Y is a normally distributed variable, we can standardize it using the formula:

Z = (Y - μ') / σ'

Then we can find the value of t using a standard normal distribution table or calculator:

Z = 1.88

t = μ' + Z * σ' = 17 + 1.88 * 4.25 = 25.99 seconds

(d) After the upgrade, a higher proportion of customers can finish the transaction within 20 seconds. This is because the mean transaction time has decreased from 20 seconds to 17 seconds, which means that more customers will have a transaction time less than or equal to 20 seconds.

Step-by-step explanation:

The function is a square root function. The negative is a reflection across the x axis. The 2 is a vertical stretch by 2. The subtraction of 1 from the x is a horizontal shift right 1 and the addition of 5 to the function is a vertical shift upwards 5. If you would like more detail let met know.

1. The solutions of the equation 6/(x+1)= x/(x-1) are x = 2 and x = 3.

2. The solutions of the equation x+ 4/x= -5 are x = -1 and x = -4.

What are the solutions ?

1. 6/(x+1) = x/(x-1)

To solve this equation, we first need to get rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators, which is (x+1)(x-1):

6(x-1) = x(x+1)

Expanding the left side, we get:

6x - 6 = x² + x

Moving all the terms to one side, we get:

x² - 5x + 6 = 0

This is a quadratic equation that can be factored as:

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

So, the solutions are x = 2 and x = 3. However, we need to check if these solutions are valid, because we cannot divide by zero.

Checking x = 2:

6/(2+1) = 2/(2-1)

2 = 2, which is true

Checking x = 3:

6/(3+1) = 3/(3-1)

3/2 = 3/2, which is true

Therefore, the solutions are x = 2 and x = 3.

2. x + 4/x = -5

To solve this equation, we first need to get rid of the fraction by multiplying both sides of the equation by x:

x² + 4 = -5x

Moving all the terms to one side, we get:

x² + 5x + 4 = 0

This is a quadratic equation that can be factored as:

(x + 1)(x + 4) = 0

So, the solutions are x = -1 and x = -4. However, we need to check if these solutions are valid, because we cannot divide by zero.

Checking x = -1:

-1 + 4/(-1) = -5

-1 - 4 = -5, which is true

Checking x = -4:

-4 + 4/(-4) = -5

-4 - 1 = -5, which is true

Therefore, the solutions are x = -1 and x = -4.

Answer: Starting with the expression:

tan(x)(cot(x) - cos(x))

Recall that cot(x) is the reciprocal of tan(x), so we can substitute cot(x) = 1/tan(x):

tan(x)(1/tan(x) - cos(x))

Simplifying:

1 - cos(x)tan(x)

Next, we can use the identity cos(x) = 1/sec(x) to eliminate the cotangent term:

1 - (1/sec(x))tan(x)

Now, we can use the identity tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x) to express the expression in terms of sine and cosine:

1 - (1/cos(x))(sin(x)/cos(x))

Simplifying:

cos(x)/cos(x) - sin(x)/cos(x)

= (cos(x) - sin(x))/cos(x)

Therefore, the simplified expression in terms of sine and cosine is:

(cos(x) - sin(x))/cos(x)

The inverse function of f, what is the value of (ƒ-¹)' (-4) -1/16 ∓ i/(8√3)

We know that the point (1,-4) is on the graph of f, so we can use this information to find the value of x for which f(x) = -4:

-4 = -x³ + 3x² + (6x)

-x³ + 3x² + 6x + 4 = 0

We can solve this equation using various methods, such as graphing, factoring, or using the cubic formula. One possible method is to use synthetic division to test factors of the constant term (4) and find one that gives a remainder of zero. By testing -1 as a factor, we get:

-1 | 1 -3 6 4

-1 4 -10

1 -4 10 -6

Therefore, the equation can be factored as:

-(x + 1)(x² - 4x + 6) = 0

Using the quadratic formula or completing the square, we can find the roots of the quadratic factor:

x = 2 ± √2i

Since the function f is not one-to-one, we must restrict its domain to make it invertible. One possible domain is x ≤ 2, so the inverse function f⁻¹(x) is:

f⁻¹(x) = 1 ± √(1 - 2x)/x

Note that there are two possible values for f⁻¹(-4), one for each branch of the inverse function. To find the value of (f⁻¹)'(-4), we need to take the derivative of the inverse function at x = -4:

(f⁻¹)'(x) = -1/x² ∓ √(1 - 2x)/2x³

(f⁻¹)'(-4) = -1/16 ∓ i/(8√3)

Therefore, the value of (f⁻¹)'(-4) is either -1/16 - i/(8√3) or -1/16 + i/(8√3), depending on which branch of the inverse function we choose.

Answer:

There are no two numbers whose product is 52 and whose sum is 11.

Step-by-step explanation:

give the 1st number is x and the 2nd number is y, then

x + y = 11 and xy = 52

x + y = 11 => y = 11 - x

x(11 - x) = 52

11x - x^2 = 52

=> x^2 - 11x + 52 = 0

Using quadratic formula: ax^2 + bx + c = 0

with a = 1, b = -11, c = 52

=> x = [-b ± √(b^2 - 4ac)]/2a

=> x = [-(-11) ± √((-11)^2 - 4x1x52)]/2x1

=> x = [11 ± √(121 - 208)]/2

=> x = [11 ± √(-87)]/2

Since the square root of a negative number is not a real number, there are no real solutions to this equation. Therefore, there are no two numbers whose product is 52 and whose sum is 11.

The vertex οf the parabοla is at the pοint (-3/2, -21/4) and the range οf the functiοn wοuld be (-21/4, infinity).

A quadratic functiοn is a functiοn οf the fοrm  where a, b, and c are cοnstants, and a is nοt equal tο 0. It is a type οf pοlynοmial functiοn that can be graphed as a parabοla, which is a symmetric curve that οpens either upwards οr dοwnwards.

Given the table οf pοints fοr the cοntinuοus quadratic functiοn h(x), we can find the vertex and range οf the functiοn. Since the functiοn is quadratic and cοntinuοus, it can be represented in the standard fοrm [tex]$f(x)=a(x-h)^{2}+k,$[/tex], where (h, k) is the vertex οf the parabοla.

Tο find the vertex, we can use the fact that the x-cοοrdinate οf the vertex is given by -b/2a, where a and b are the cοefficients οf the quadratic term and the linear term, respectively. In this case, a = 1 (since the functiοn is cοntinuοus and quadratic), and b can be fοund using any twο pοints οn the parabοla:

[tex]\rm b=(h(x_2)-h(x_1))/(x_2-x1)=(4-7)/(-2+1)=3$[/tex]

Therefοre, the x-cοοrdinate οf the vertex is x = -b/2a = -3/2. Tο find the y-cοοrdinate οf the vertex, we can evaluate the functiοn at this value οf x:

[tex]$\rm h(-3/2)=(1)(-3/2-h)^{2}+k$[/tex]

Tο sοlve fοr k, we can use οne οf the pοints οn the parabοla, say (-6, 12):

[tex]$12=(1)(-6-h)^{2}+k\,$[/tex]

Expanding and simplifying, we get:

[tex]$12=(h-6)^{2}+k$[/tex]

Substituting -3/2 fοr h, we get:

[tex]$\begin{array}{l}{{12=(-(3/2)-6)^{2}+k}}\\\\ {{12=81/4+k}}\\\\ {{k=-21/4}}\end{array}$[/tex]

Therefοre, the vertex οf the parabοla is at the pοint (-3/2, -21/4).

Tο find the range οf the functiοn, we can lοοk at the shape οf the parabοla. Since the cοefficient οf the quadratic term is pοsitive, the parabοla οpens upwards, and the vertex is the lοwest pοint οn the graph. Therefοre, the range οf the functiοn is all real numbers greater than οr equal tο the y-cοοrdinate οf the vertex, which is -21/4. In interval nοtatiοn, we can write the range as (-21/4, infinity).

Hence, the vertex οf the parabοla is at the pοint (-3/2, -21/4) and the range οf the functiοn wοuld be (-21/4, infinity).

The probability of selecting a vowel first and then not a vowel second is 2/6 x 5/5 = 10/30 = 1/3.

Probability is a branch of mathematics that deals with the likelihood of something happening. It is used to quantify the chance of a certain event occurring and can help to predict the outcome of a given situation. Probability is based on the concept of randomness, which is the idea that an event's outcome is determined by chance and cannot be controlled or predicted.

The word "replacement" contains 2 vowels (e,a) and 4 consonants (r,p,l,c). Therefore, the probability of selecting a vowel first is 2/6 (2 out of 6 cards are vowels). Since there are 5 cards left after the first selection, the probability of selecting a non-vowel second is 5/5 (5 out of 5 cards are non-vowels).

Therefore, the probability of selecting a vowel first and then not a vowel second is 2/6 x 5/5 = 10/30 = 1/3.
