The quadratic function for the value of David's investment indicates;

(i) $45,000

(ii) 9.375 months

What is a quadratic function?

A quadratic function is a function that can be expressed in the form; f(x) = a·x² + b·x + c, where a ≠ 0, and a, b, and c are numbers.

The model of the value of the investment in the bank obtained from the amount of his retirement funds David invested in the bank can be presented as follows;

a = 45 + 75·t - 4·t²

Where;

a = The value of the investment in thousand of dollars after t months

t = The number of months of the investment

(i) The initial amount David invested can be found by plugging in t = 0, in the function for the amount David invested in the bank, as follows;

a = 45 + 75 × 0 - 4 × 0² = 45

The initial amount David invested is; a = $45,000

(ii) The number of months it takes for David investment to reach a maximum value can be found from the quadratic function as follows;

The number of months t(max) at the maximum amount is; t(max) = -75/(2 × (-4)) = 9.375

Therefore, it will take 9.375 months for David's investment to reach a maximum value

How many minutes would you have to exercise each day to have a resting heart rate of 60 beats per minute? Equation

Answers

To determine the number of minutes you would have to exercise each day to have a resting heart rate of 60 beats per minute, we need to consider the relationship between exercise and heart rate.

Regular exercise can help lower resting heart rate as it strengthens the cardiovascular system. The American Heart Association recommends engaging in moderate-intensity aerobic exercise for at least 150 minutes per week to maintain cardiovascular health.

If we assume that you exercise evenly throughout the week, we can calculate the daily exercise time as follows:

150 minutes per week ÷ 7 days = approximately 21.43 minutes per day.

Therefore, if you exercise for approximately 21.43 minutes per day, it can contribute to maintaining a healthy resting heart rate. It's important to note that individual results may vary, and consulting with a healthcare professional is always recommended before starting or modifying an exercise routine.

However, it's crucial to understand that exercise alone may not be the sole factor affecting resting heart rate. Other factors, such as genetics, overall health, stress levels, and lifestyle choices, can also influence heart rate. Additionally, achieving a resting heart rate of 60 beats per minute may not be feasible or suitable for everyone, as the ideal range can vary based on individual circumstances.

Therefore, while regular exercise can be beneficial for cardiovascular health, it's essential to consider personalized factors and consult with a healthcare professional for tailored advice on achieving and maintaining a healthy resting heart rate.

A grocery delivery service subscriber pays $135.99 per year for unlimited deliveries. The subscriber pays for the service using a credit card with a 16.99% APR. If the balance is paid off after one month of interest charges, how much more will have been paid instead of using cash?

$19.30
$23.10
$1.93
$3.88

Answers

Answer:

C)  $1.93

Step-by-step explanation:

To calculate the additional amount paid for using the credit card instead of cash, we need to consider the interest charges incurred over one month.

The annual interest rate is 16.99%.

Calculate the monthly interest rate by dividing the annual interest rate by 12 (number of months in a year):

[tex]\textsf{Monthly interest rate} = \dfrac{16.99\%}{12} =1.4158333...\%=0.014158333...[/tex]

Now we can calculate the interest charged on the annual subscription fee for one month:

[tex]\begin{aligned}\textsf{Interest charged}& = \textsf{Annual subscription fee} \times \textsf{Monthly interest rate}\\\\&=\$135.99 \times 0.014158333...\\\\&=1.92539175\\\\&= \$1.93\; \textsf{(nearest cent)}\end{aligned}[/tex]

Therefore, the additional amount paid instead of using cash is approximately $1.93.

Answer:

$1.93

Step-by-step explanation:

The first step is to find out how much interest will accrue in one month on the annual fee of $135.99.

[tex]\rm\implies{Interest = \dfrac{APR \times Balance}{12}}[/tex]

Substitute the given values into the formula:

[tex]\begin{aligned}\rm\implies Interest& =\rm \dfrac{16.99 \times 135.99}{12}\\&=\rm\dfrac{23.104701}{12}\\& \approx \boxed{\rm{\$1.93}}\end{aligned}[/tex]

[tex]\therefore[/tex] The subscriber will have paid an additional $1.93 in interest charges by using their credit card instead of paying in cash.

this extra $20 that’s only $290, where did the other $10 go?”
Explain what is wrong with the Bell Boy’s thoughts, and what is the correct math here.

Answers

Answer:

Step-by-step explanation:

The bell boy added $270 and $20 incorrectly. The $20 bill was something that was returned due to overcharching. On the other hand, $270 was the amount that they paid for their room. This only means that $20 should be deducted from $270 and that's the amount that they paid for their room while $30 and $20 are the amount that the bell boy received as a tip

Total money of the three men: 3($100) = $300

They paid $270 for the room: $300 - $270 = $30

Tip for the bell boy: $30 - $30 = $0

Amount overcharged to them: $0 + $20 = $20

Tip to the bell boy: $20 - $20 = $0

They were left with no more money from the original $300.

The five-number summary for the height of 18 sunflowers include:

Minimum (Min) = 40.First quartile (Q₁) = 50.Median (Med) = 55.Third quartile (Q₃) = 55.75.Maximum (Max) = 63.

How to determine the five-number summary for the data?

In order to determine the five-number summary for the height of 18 sunflowers, we would arrange the data set in an ascending order:

40, 45, 47, 50, 50, 51, 51, 51, 55, 55, 55, 55, 55, 55, 58, 58, 62, 63

From the data set above, we can logically deduce that the minimum (Min) is equal to 40.

For the first quartile (Q₁), we have:

Q₁ = [(n + 1)/4]th term

Q₁ = (18 + 1)/4

Q₁ = 4.75th term

Q₁ = 4th term + 0.75(5th term - 4th term)

Q₁ = 50 + 0.75(50 - 50)

Q₁ = 50 + 0.75(0)

Q₁ = 50.

From the data set above, we can logically deduce that the median (Med) is given by:

Median = (9th term + 10th term)/2

Median = (55 + 55)/2

Median = 55

For the third quartile (Q₃), we have:

Q₃ = [3(n + 1)/4]th term

Q₃ = 3 × 4.75

Q₃ = 14.25th term

Q₃ = 14th term + 0.25(15th term - 14th term)

Q₃ = 55 + 0.25(58 - 55)

Q₃ = 55 + 0.25(3)

Q₃ = 55.75

In conclusion, the maximum height is equal to 63.

Out of 240 racers who started the marathon, 214 completed the race, 23 gave up, and 3 were disqualified. What percentage did not complete the marathon?

Answers

To find the percentage of racers who did not complete the marathon, we need to calculate the proportion of racers who gave up or were disqualified out of the total number of racers who started the marathon.

The number of racers who did not complete the marathon is the sum of those who gave up and those who were disqualified:

Number of racers who did not complete = Number who gave up + Number who were disqualified

                                     = 23 + 3

                                     = 26

Now, we can calculate the percentage using the formula:

Percentage = (Number who did not complete / Total number who started) * 100

Percentage = (26 / 240) * 100

Percentage ≈ 10.83%

Therefore, approximately 10.83% of the racers did not complete the marathon.

This percentage represents the portion of racers who were unable to finish the race due to various reasons such as fatigue, injury, or disqualification. It highlights the challenges and demands of participating in a marathon and the determination required to complete the race.

The percentage provides a quantitative measure of the proportion of racers who were not able to reach the finish line, giving an understanding of the attrition rate in the marathon.

A tree measuring 15 feet in height casts a shadow that is eight feet long. Find the diagonal measurement from the top of the tree to the end of the shadow.
• Draw an image of the problem.
• Use the Pythagorean Theorem to solve for the diagonal.
• The conversion ratio of feet to meters is 1 meter / 3.3 feet. Convert all measures of the problem into meters.
• An arborist is called out to do maintenance the tree in this problem. If they are paid $2.60 per the square area (in meters) of the tree and its shadow then how much money will they make?

Answers

The arborist will make approximately $28.65.

First, let's draw an image of the problem:

Using the Pythagorean Theorem, we can find the diagonal measurement (d) from the top of the tree to the end of the shadow:

d² = h² + s²

Substituting the given values:

d² = 15² + 8²

d² = 225 + 64

d² = 289

Taking the square root of both sides:

d = √289

d = 17 feet

Now, let's convert the measurements from feet to meters using the conversion ratio:

1 meter / 3.3 feet

Height in meters: 15 feet [tex]\times[/tex] (1 meter / 3.3 feet) ≈ 4.55 meters

Shadow in meters: 8 feet [tex]\times[/tex] (1 meter / 3.3 feet) ≈ 2.42 meters

Diagonal in meters: 17 feet [tex]\times[/tex] (1 meter / 3.3 feet) ≈ 5.15 meters

To calculate the arborist's earnings, we need to find the square area (in square meters) of the tree and its shadow:

Area = Height [tex]\times[/tex] Shadow

Area = 4.55 meters [tex]\times[/tex] 2.42 meters

Area ≈ 11.02 square meters

Finally, the arborist will earn:

To find the value of 'x', we can use the property of parallel lines that states when a transversal intersects two parallel lines, the corresponding angles are equal.

In triangle ABC, we have DE parallel to BC. Therefore, we can conclude that triangle ADE is similar to triangle ABC.

Using the property of similar triangles, we can set up the following proportion:

[tex]\displaystyle\sf \dfrac{AD}{DB} = \dfrac{AE}{EC}[/tex]

Substituting the given values:

[tex]\displaystyle\sf \dfrac{6x - 7}{4x - 3} = \dfrac{3x - 3}{2x - 1}[/tex]

To solve this proportion for 'x', we can cross-multiply:

[tex]\displaystyle\sf (6x - 7)(2x - 1) = (4x - 3)(3x - 3)[/tex]

Expanding both sides:

[tex]\displaystyle\sf 12x^{2} - 6x - 14x + 7 = 12x^{2} - 9x - 12x + 9[/tex]

Combining like terms:

[tex]\displaystyle\sf 12x^{2} - 20x + 7 = 12x^{2} - 21x + 9[/tex]

Moving all terms to one side:

[tex]\displaystyle\sf 12x^{2} - 12x^{2} - 20x + 21x = 9 - 7[/tex]

Answers

The equation of the line in point-slope form, slope-intercept form and standard form is y - 4 = 2( x - 2 ), y = 2x and 2x - y = 0 respectively.

What is the equation of line passing through the points (2,4) and (3,6)?

The slope-intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given that the line passes through points (2,4) and (3,6).

First, we determine the slope:

[tex]Slope\ m = \frac{y_2 - y_1}{x_2 - x_1} \\\\Slope\ m = \frac{6 - 4}{3-2} \\\\Slope\ m = \frac{2}{1} \\\\Slope\ m = 2[/tex]

Now, plug the slope m = 2 and point (2,4) into the point-slope form:

( y - y₁ ) = m( x - x₁ )

y - 4 = 2( x - 2 )

Solve in slope-intercept form:

y - 4 = 2( x - 2 )

y - 4 = 2x - 4

y = 2x - 4 + 4

y = 2x

Solve in standard form:

Ax + Bx = C

y - y  = 2x - y

0 = 2x - y

Reorder:

2x - y = 0

Therefore, the standard form is  2x - y = 0.

if the standard deviation of 3,6,x,7,5 is square root 2 find the positive value of x​

Answers

Using the formula for the standard deviation and solving for x, we will get:

x = 7.6

How to find the value of x?

To find the positive value of 'x' in the given set of numbers (3, 6, x, 7, 5) when the standard deviation is √2, we can use the formula for standard deviation.

The formula for calculating the sample standard deviation is as follows:

σ = √[(Σ(xi - m)²) / (n - 1)]

Where:

σ is the standard deviationΣ is the summation symbolxi represents each value in the datasetm is the mean of the datasetn is the number of values in the dataset

First, let's calculate the mean (m) of the given set of numbers:

Mean (m) = (3 + 6 + x + 7 + 5) / 5 = (21 + x) / 5

Next, let's substitute the values into the standard deviation formula:

√2 = √[( (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)² ) / 4]

Simplifying the equation:

2 = [( (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)² ) / 4]

Multiplying both sides of the equation by 4:

8 = (3 - (21 + x) / 5)² + (6 - (21 + x) / 5)² + (x - (21 + x) / 5)² + (7 - (21 + x) / 5)² + (5 - (21 + x) / 5)²

Expanding and simplifying:

8 = (15 - (21 + x) / 5)² + (30 - (21 + x) / 5)² + (5x/5)² + (35 - (21 + x) / 5)² + (25 - (21 + x) / 5)²

8 = (15 - (21 + x) / 5)² + (30 - (21 + x) / 5)² + x² + (35 - (21 + x) / 5)² + (25 - (21 + x) / 5)²

Expanding and simplifying further:

8 = (225 - 2(21 + x) + (21 + x)² / 25) + (900 - 2(21 + x) + (21 + x)² / 25) + x² + (1225 - 2(21 + x) + (21 + x)² / 25) + (625 - 2(21 + x) + (21 + x)² / 25)

Combining like terms:

8 = (225 + 900 + 1225 + 625) / 25 - 10(21 + x) + 5(21 + x)² / 25 + x²

8 = 2975 / 25 - 10(21 + x) + 5(21 + x)² / 25 + x²

Simplifying:

8 = 119 - 10(21 + x) + (21 + x)² / 5 + x²

Rearranging the terms:

8 - 119 = -10(21 + x) + (21 + x)² / 5 + x²

-111 = -10(21 + x) + (21 + x)² / 5 + x²

Multiplying through by 5 to eliminate the fraction:

-555 = -50(21 + x) + (21 + x)² + 5x²

Expanding and simplifying:

-555 = -1050 - 50x + x² + 441 + 42x + x² + 5x²

Combining like terms:

0 = 7x² - 8x - 114

Now, we can solve this quadratic equation to find the value of 'x'.

Using the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 7, b = -8, and c = -114.

Plugging the values into the formula:

x = (-(-8) ± √((-8)² - 4(7)(-114))) / (2(7))

Simplifying:

x = (8 ± √(64 + 3192)) / 14

x = (8 ± 2√(814)) / 14

x = (4 ± √(814)) / 7

Therefore, the values of 'x' that satisfy the given equation are approximately:

x ≈ (4 + √(814)) / 7 ≈ 7.62

x ≈ (4 - √(814)) / 7 ≈ -0.29

Since we are looking for the positive value of 'x', the solution is:

x ≈ 7.6

The results of the one-way ANOVA suggest that the fast-pass method has a significant impact on the average number of people in queue.

How to explain the ANOVA

The F-statistic for this example is 3.53. The p-value for the one-way ANOVA is calculated using the F-distribution. The p-value for this example is 0.029.

The p-value is less than the significance level of 0.05, so we can reject the null hypothesis. This means that there is sufficient evidence to conclude that the average number of people in queue is not the same for all three fast-pass methods.

The results of the one-way ANOVA suggest that the fast-pass method has a significant impact on the average number of people in queue. Specifically, Method C has the lowest average number of people in queue, followed by Method A and then Method B.

The population of a town increased from 3700 in 2005 to 5900 in 2009. Find the absolute and relative (percent) increase.

Absolute increase:


Relative increase:
%

Answers

The absolute increase in population is 2200, and the relative increase is approximately 59.46%.

To find the absolute and relative increase in population, we can use the following formulas:

Absolute increase = Final value - Initial value

Relative increase = (Absolute increase / Initial value) * 100%

Given the population in 2005 is 3700 and the population in 2009 is 5900, we can calculate the absolute and relative increase as follows:

Absolute increase = 5900 - 3700 = 2200

To calculate the relative increase, we need to divide the absolute increase by the initial value and then multiply by 100:

Relative increase = (2200 / 3700) * 100% ≈ 59.46%

Therefore, the absolute increase in population is 2200, and the relative increase is approximately 59.46%.

The absolute increase represents the actual difference in population count between the two years, while the relative increase gives us the percentage change relative to the initial value. In this case, the population increased by 2200 individuals, and the relative increase indicates that the population grew by approximately 59.46% over the given period.

Note that the relative increase is expressed as a percentage, which makes it easier to compare changes across different populations or time periods.

Question 4 A ladder 12 m long leans against a vertical wall with its foot 4.5 m away from the base of the wall as shown. What height does the ladder reach up the wall? (Leave your answer in 2 decimal places).​

Answers

To find the height that the ladder reaches up the wall, we can use the Pythagorean theorem.

which relates the lengths of the sides of a right triangle. In this case, the ladder forms the hypotenuse, the distance from the base of the wall to the foot of the ladder is one side (4.5 m), and the height we want to find is the other side.

In this case, the ladder forms the hypotenuse, and the distance from the foot of the ladder to the base of the wall is one of the sides.

Let's denote the height of the ladder on the wall as 'h'. According to the problem, the length of the ladder is 12 m, and the distance from the foot of the ladder to the base of the wall is 4.5 m.

Using the Pythagorean theorem, we have:

a^2 + b^2 = c^2

where a represents the height, b represents the distance from the base of the wall, and c represents the length of the ladder.

Substituting the given values, we have:

a^2 + (4.5)^2 = (12)^2

Simplifying:

a^2 + 20.25 = 144

a^2 = 144 - 20.25

a^2 = 123.75

Taking the square root of both sides:

a ≈ 11.11

Therefore, the ladder reaches a height of approximately 11.11 meters up the wall.

As Caterpillar does have multiple issues of bonds outstanding, we, for simplicity purpose, just use its longest-maturity bond. So click for twice on "Maturity" (within the first row of the table) until the blue down arrow shows up, the Caterpillar bond list will be reorganized with the longest maturities on the top. You will see the longest CAT bond will mature at 03/01/2097. Click on the symbol of that specific bond, you will see even more details.

Hints: a) For the CAPM approach, we have already done so in Chapter 06 HW, so can just use our prior relevant HW answer; b) For the DCF approach, you can use CAT's most current share price as P0, "trailing dividend rate" amount (in "Statistics") as D0, and "Analysis" ==>"Growth Estimates"==>"Next 5 year (per annum)" amount as G; c) For own-bond-yield-plus-risk-premium approach, you can simply add a subjective 4% (i.e., the middle point between 3 and 5 percents) on top of Caterpillar's longest-maturity (in this case, 03/01/2097) bond yield. 3) For CAT's capital structure weights, we can go to Finance Yahoo and use CAT's "Statistics" to find "Market Cap (intraday)" for total common equity value E, to find "Total Debt (mrq)" for total debt value D, and then figure out the respective weights of equity and debt capital Wce and Wd.
