Answers

Answer 1

The volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis is (πln(3)3)/3.

To find the volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis, we can use the disk method. The disk method involves slicing the region into thin disks and adding up their volumes.

The volume of each disk is πr2h, where r is the radius of the disk and h is the thickness of the disk. In this case, the radius of each disk is x and the thickness is dx.

So, the volume of the region is:

V = ∫0ln(3)πx2dx

We can use the power rule for integration to solve this integral:

V = π∫0ln(3)x2dx = π[(x3)/3]0ln(3) = π[(ln(3)3)/3 - (03)/3] = (πln(3)3)/3

Therefore, the volume generated by rotating the region in the first quadrant bounded by y = ex and the x-axis from x = 0 to x = ln(3) about the y-axis is (πln(3)3)/3. This is the exact form of the volume.

A global research study found that the majority of today's working women would prefer a better 'work-life balance' to an increased salary. One of the most important contributors to 'work-life balance' identified by the survey was 'flexibility' with 46% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women. (Round answers to four decimal places.) a) What is the probability that, in the sample, fewer than 50% say that having a flexible work schedule is either very important or extremely important to their career success? b) What is the probability that, in the sample, more than 43% say that having a flexible work schedule is either very important or extremely important to their career success?

Answers

z = (x - np) / σ
z = (43 - 100(0.50)) / 0.05
z = -1.4
P(z > -1.4) = 0.9192

a) The number of working women in the sample is 100. The majority of women prefer a better 'work-life balance' to a higher salary, according to a global research study. The majority in percentage is 50% or greater, which implies that 50% of 100 working women or more prefer a better work-life balance to an increased salary. If we assume that the null hypothesis is correct and the number of women who say having a flexible work schedule is important is exactly 50, the standard error for the sample can be calculated as follows:

σ = sqrt(p(1-p)/n)
σ = sqrt(0.50(1-0.50)/100)
σ = 0.05

P(x<50) can be calculated as follows:

z = (x - np) / σ
z = (50 - 100(0.50)) / 0.05
z = -20
P(z < -20) = 0

Therefore, the probability that fewer than 50% of the sample say that having a flexible work schedule is either very important or extremely important to their career success is 0.

b) The proportion of women who said having a flexible work schedule is very important or extremely important to their career success is more than 43%. That implies the number of women in the sample who say having a flexible work schedule is important is greater than 43.

P(x > 43) can be calculated as follows:

z = (x - np) / σ
z = (43 - 100(0.50)) / 0.05
z = -1.4
P(z > -1.4) = 0.9192

Therefore, the probability that more than 43% of the sample says having a flexible work schedule is very important or extremely important to their career success is 0.9192.

which equation represents a tangent function with a domain of all real numbers such that where n is an integer?

Answers

The tangent function is defined as the ratio of the sine function to the cosine function. It is periodic with a period of pi and has vertical asymptotes at odd multiples of pi/2. An equation for a tangent function with a domain of all real numbers and n as an integer is given by the following equation:
y = tan(x + n(pi))


The tangent function is defined as the ratio of the sine function to the cosine function, and it is periodic with a period of pi. It has vertical asymptotes at odd multiples of pi/2.
The tangent function can be represented by the following equation:
y = tan(x)
Where x is the angle measured in radians.
If we want to shift the graph of the tangent function by a certain amount, n, in the horizontal direction, we can use the following equation:
y = tan(x + n(pi))
Where n is an integer.
For example, if n = 2, then the graph of the tangent function would be shifted 2pi units to the left, and the equation would be:
y = tan(x - 2pi)
If n = 3, then the graph of the tangent function would be shifted 3pi units to the left, and the equation would be:
y = tan(x - 3pi)

We find the following conclusions concerning the telegraph wire:

Case 1: The perimeter of the circle is equal to 20π centimeters.

Case 2: The extra length for the telegraph wire is equal to 10π meters.

How to determine the perimeter of a circle

In this problem we find two cases where the perimeter of a circle must be computed for a telegraph wire, this can be done by using the following formula:

s = 2π · r

Where:

s - Perimeterr - Radius

Now we proceed to determine the perimeter for each case.

Case 1: (Please notice that diameter is twice the radius)

s = 2π · (20 / 2)

s = 20π cm

The circle has a perimeter of 20π centimeters.

Case 2: (The Earth has a radius of 6371000 meters)

Δs = 2π · (6371005 - 6371000)

Δs = 2π · 5

Δs = 10π m

Answers

a) The probability of a randomly selected diner waits less than 8 minutes for a table is 0.4

b) The probability of a randomly selected diner waits more than 1.5 minutes is 0.925

Given, wait times of between 0 and 20 minutes at a local restaurant follow a uniform distribution.

The probability density function of a uniform distribution is given by

f(x) = {1/(b-a)} where a ≤ x ≤ b

where a = 0 and b = 20

Therefore, the probability density function of f(x) = 1/20 for 0 ≤ x ≤ 20

For the  probability that a randomly selected diner waits between 2 and 7.5 minutes for a table, we need to find the area under the curve from x = 2 to x = 7.5

∴ P(2 ≤ x ≤ 7.5) = ∫₂⁷.⁵(1/20) dx

= 5.5/20 ⇒ 0.275

a) We need to find the area under the curve from x = 0 to x = 8

P(x < 8) = ∫₀⁸(1/20) dx

= 8/20 ⇒ 0.4

b) We need to find the area under the curve from x = 1.5 to x = 20

P(x > 1.5) = ∫₁.₅²⁰(1/20) dx

William bought a 0. 5 liter bottle of liquid plant food he uses 40 milliliters a week what measurements are given

Answers

One bottle of liquid plant food is enough for at least 12 weeks, and potentially a bit more.

William uses 40 milliliters of liquid plant food per week, so to find out how much plant food he needs for 12 weeks, we can simply multiply the weekly usage by the number of weeks:

Amount of plant food needed for 12 weeks = 40 milliliters/week x 12 weeks = 480 milliliters

So, William needs 480 milliliters of liquid plant food for 12 weeks.

Since the bottle of liquid plant food, William purchased contains 0.5 liters or 500 milliliters of liquid plant food, we can see that one bottle is enough for 12 weeks since 480 milliliters is less than the total amount of liquid plant food in the bottle.

In fact, we can calculate how many weeks one bottle of liquid plant food will last William by dividing the total amount of liquid plant food in the bottle by the amount used per week:

Time to use up the liquid plant food = (Total amount of liquid plant food) / (Amount used per week) = 500 ml / 40 ml/week ≈ 12.5 weeks

So, we can say that one bottle of liquid plant food is enough for at least 12 weeks, and potentially a bit more.

What is a mixed number with the same denominator for 3 7/8

Answers

The improper fraction that is equivalent to 3 7/8 is 31/8.

A mixed number consists of a whole number and a proper fraction. In the case of 3 7/8, the whole number is 3 and the proper fraction is 7/8.

To convert a mixed number to an improper fraction, you need to first convert the whole number to a fraction by multiplying it by the denominator of the fraction in the mixed number. In this case, the denominator of the fraction is 8, so we multiply 3 by 8 to get 24.

Next, you add the numerator of the fraction to the result of the multiplication. In this case, the numerator is 7, so we add it to 24 to get 31.

3 7/8 = (3 x 8 + 7) / 8

Using the definition of a straight angle, the measure of angle MON is calculated as: 130°.

What is a Straight Angle?

A straight angle is an angle that measures exactly 180 degrees. It is a flat angle, which means it has no curvature and looks like a straight line.

Therefore, we have:

m∠LOM + m∠MON = 180 [straight angle is equal to 180 degrees]

Substitute:

4x + 30 + 8x + 90 = 180

Solve for x:

12x + 120 = 180

12x = 180 - 120

12x = 60

x = 60/12

x = 5

Answers

Since, that the total interest that will be paid on a 40-year mortgage from a home loan of $100,000 is going to be $480,000. Then,  the payments each month if the payments are to pay off both the loan and the interest will be $1,504.

The 40-year loan has the lowest monthly payment at $1,504. But that only means "saving" $183 per month on the 30-year loan. When considering the total price of the house in this example, adding an additional 10 years to the term of the loan seems overkill, reducing the monthly payment by less than $200.

A 40-year loan doesn't sound like a good deal. But for homeowners struggling to meet their monthly payments and get a 40-year loan modification, the lower payments could have a big impact.

Comparing the 30-year and 15-year numbers is even more extreme. The monthly payment on the 15-year loan is an additional $700. Some buyers can afford higher payments. The advantage of the 15-year loan is that the total interest paid on the loan is $103,218, compared to $289,970 for the 30-year loan. Fifteen years seems to pass so quickly, and it's an exciting feeling to stop paying.

Objections to the 15-year loan could include a missed opportunity. With an interest rate of 4.67% on the 30-year loan, one can expect a higher rate of return in the long run by investing heavily in the stock market. But that raises the question of whether the $700 a month in cash freed up by the 30-year loan will be invested. It might be tempting to spend that money on a more expensive car than the one you would otherwise have purchased.

A family's needs, including space, savings and investment for retirement and education, as well as many household expenses should be considered when deciding which home to buy and the term of the loan. At a minimum, homebuyers need to understand how the different types of loans work.

The width of a rectangular field is 20 feet less than its length. The area of the field is 12,000 ft2. What is the length of the field?
80 ft
100 ft
120 ft
140 ft

Answers

Answer:

120 ft

Step-by-step explanation:

Let's assume that the length of the field is x feet. Then, according to the problem statement, the width of the field is (x - 20) feet.

The area of a rectangle is given by the formula A = length x width. So, we can write:

x(x - 20) = 12,000

Expanding the left-hand side, we get:

x^2 - 20x = 12,000

Bringing all the terms to one side, we have:

x^2 - 20x - 12,000 = 0

Now, we can solve this quadratic equation using the quadratic formula:

x = (-(-20) ± sqrt((-20)^2 - 4(1)(-12,000))) / (2(1))

x = (20 ± sqrt(20^2 + 48,000)) / 2

x = (20 ± 220) / 2

We discard the negative root, since a length cannot be negative, and we get:

x = 120

Therefore, the length of the field is 120 feet.

From a full deck of 52 bridge cards you receive 6 cards. (a) What is the probability that they are all of the same suit? (b) What is the probability that they contain only one pair?

Answers

The probability of drawing 6 cards of the same suit is 0.002% while the probability of drawing a hand containing only one pair is 42.3%.

How to Solve the Probability?

(a) The probability of drawing 6 cards of the same suit can be calculated as follows:

First, choose one of the four suits. There are 4 ways to do this.

Next, choose 6 cards from the chosen suit. There are 13 cards in each suit, so there are C(13,6) ways to do this.

Finally, choose any 6 cards from the deck. There are C(52,6) ways to do this.

Therefore, the probability of drawing 6 cards of the same suit is:

P(6 cards of the same suit) = (4 * C(13,6)) / C(52,6) ≈ 0.002%

(b) The probability of drawing a hand containing only one pair can be calculated as follows:

First, choose a rank for the pair. There are 13 ranks to choose from.

Next, choose 2 cards of the chosen rank. There are C(4,2) ways to do this.

Then, choose 4 cards from the remaining 48 cards. There are C(48,4) ways to do this.

Therefore, the probability of drawing a hand containing only one pair is:

P(only one pair) = (13 * C(4,2) * C(48,4)) / C(52,6) ≈ 42.3%

Answer:

D is (3, -2)
Option D

Step-by-step explanation:

If E is the midpoint of DF then the x-distance between D and E must be the same as that between E and F and similarly for the y-distance

In addition, the x, y coordinates of D must be less than the x, y coordinates for E

x-distance from E to F = 5- 4 = 1

x-distance from D to E = 1 so x-coordinate of D = 4 - 1 = 3

y-distance from E to F = 8 - 3 =  5

y-distance from D to E = 3 - 5 = -2

So coordinate of D is(3, -2)

Quadrilateral MNOP has vertices M(-2,4) N(-2,1) O(3,1) and P(3,4). what are the coordinates of the image of point P after a reflection across the X-axis??

Answers

After just a reflection along the [tex]X-axis[/tex], a quadrilateral [tex]MNOP[/tex] of position [tex]P[/tex] is [tex](3, -4)[/tex].

Describe the quadrilateral form.

Four closed sides are making up a quadrilateral. Quadrilaterals are the following figures: Designed by Raphael. a four-sided figure. There is just one pair of parallel sides to the form, and there are no right angles.

With an example, define a quadrilateral.

A closed form known as a quadrilateral is known to be have sides with various widths and lengths. It is a closed polygon in two dimensions with four vertices, four angles, and four sides. Some examples of a quadrilateral are a cohesion and coherence, parallelogram, rectangle, rhombus, square, and kite.

When a point is reflected across the [tex]X-axis[/tex], the [tex]X-[/tex]coordinate stays the same, but the [tex]Y-[/tex]coordinate is multiplied by [tex]-1[/tex].

So to find the image of point [tex]P[/tex] after a reflection across the [tex]X-axis[/tex], we keep the [tex]X-[/tex]coordinate of [tex]P[/tex] the same (which is 3) and multiply the [tex]Y-[/tex]coordinate by [tex]-1[/tex]

New [tex]Y-[/tex]coordinate of [tex]P = -1 * 4 = -4[/tex]

Therefore, the image of point [tex]P[/tex] after a reflection across the [tex]X-axis[/tex] is [tex](3, -4)[/tex].
