Marco solves the equation 4sin(3x) 0. 25 ≤ 2sin(3x) − 0. 3 by graphing y = 2sin(3x) and y = −0. 55. He then locates the intervals on which 2sin(3x) is less than or equal to −0. 55. Is Marco's solution method valid? Explain.

Answers

Answer 1



Marco's solution method of graphing the equation  y = 2sin(3x) and y = -0.55 to locate the intervals where 2sin(3x) is less than or equal to -0.55 is valid. By graphing the functions, Marco can visually determine the intervals where the inequality is satisfied.

However, to obtain a precise and accurate solution, he should also consider other methods, such as algebraic manipulation or solving the equation analytically.

Graphing the functions y = 2sin(3x) and y = -0.55 allows Marco to visualize the behavior of the two functions and identify the intervals where 2sin(3x) is less than or equal to -0.55. By comparing the graphs of the two functions, he can determine the values of x for which the inequality is satisfied.

While graphing provides a visual understanding of the solution, it is important to note that it might not yield an exact solution. Graphs can provide an approximate solution, but for precise results, algebraic manipulation or analytical methods should be employed. These methods can provide a more accurate and rigorous solution to the equation.

Irma's family went to the beach. They got to the beach at 1:57 P.M. and swam in the ocean for 1 hour and 35 minutes. Then they built sand castles for 48 minutes and played volleyball for 1 hour and 56 minutes before heading home. What time was it when Irma's family left the beach?

Answers

Given that Irma's family arrived at the beach at 1:57 PM, swam in the ocean for 1 hour and 35 minutes, built sandcastles for 48 minutes, and played volleyball for 1 hour and 56 minutes. We need to determine the time when Irma's family left the beach.

To find out, we will need to add up the total time that they spent at the beach:

1 hour and 35 minutes spent swimming in the ocean + 48 minutes spent building sandcastles + 1 hour and 56 minutes spent playing volleyball = 4 hours and 19 minutes

Therefore, if Irma's family arrived at the beach at 1:57 PM, and they spent a total of 4 hours and 19 minutes there, then they would have left the beach at:

1:57 PM + 4 hours and 19 minutes = 6:16 PM

Therefore, the time when Irma's family left the beach was 6:16 PM

In summary, Irma's family arrived at the beach at 1:57 PM, and spent a total of 4 hours and 19 minutes there. They spent 1 hour and 35 minutes swimming in the ocean, 48 minutes building sandcastles, and 1 hour and 56 minutes playing volleyball.

Split apart 1 1/2 into its whole part and its fractional part.

Answers

1 1/2 can be split apart into 1 as the whole part and 3/2 as the fractional part.

To split apart the mixed number 1 1/2 into its whole part and fractional part, we need to understand the components of a mixed number.

A mixed number consists of a whole number part and a fractional part. In this case, 1 1/2 is a mixed number where 1 is the whole number part and 1/2 is the fractional part.

To separate the whole part and fractional part, we can rewrite the mixed number as an improper fraction.

The whole number part, 1, can be written as a fraction with a denominator of 1:

1 = 1/1

Now, let's convert the fractional part, 1/2, into an improper fraction. To do this, we multiply the whole number part, 1, by the denominator of the fraction and add the numerator:

1 x 2 + 1 = 2 + 1 = 3

The improper fraction is 3/2.

So, we have the whole part as 1 and the fractional part as 3/2.

It's worth noting that the whole part represents the whole number portion of the mixed number, while the fractional part represents the remaining portion of the number that is less than a whole unit.

Draw a line through the point (-2,2) with a slope of -3. Draw a line through the point (2,-2) with a slope of -3. What do you notice about the two lines? Parallel, Perpendicular of Intersecting?

Answers

The answer is parallel.The slope of the two lines is the same, i.e., -3. Hence, both lines are parallel to each other. Therefore, the answer is parallel.

First of all, we have to find the equation of each line, given the point-slope form:

Slope of the line passing through (-2, 2) with a slope of -3:

Since the slope of the line is -3 and it passes through (-2, 2), the equation is:

y - 2 = -3(x + 2) ⇒ y - 2 = -3x - 6 ⇒ y = -3x - 4

The equation of the first line is y = -3x - 4.

Slope of the line passing through (2, -2) with a slope of -3:

Since the slope of the line is -3 and it passes through (2, -2), the equation is:

y - (-2) = -3(x - 2) ⇒ y + 2 = -3x + 6 ⇒ y = -3x + 4

The equation of the second line is y = -3x + 4.

Now, let's analyze the slopes of both lines. The slope of the two lines is the same, i.e., -3. Hence, both lines are parallel to each other. Therefore, the answer is parallel.

A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4. 75 per pound. If peanuts cost $4. 00 per pound and cashews cost $6. 50 per pound, how many pounds of each should he use? Let p = pounds of peanuts and let c = pounds of cashews. Write a system of equations that could be used to solve the problem.

Answers

The system of equations that could be used to solve the problem is:

1. p + c = 10   (equation representing the total weight of the mixture)

2. 4.00p + 6.50c = 4.75(10)   (equation representing the cost of the mixture)

Let's break down the given information and use it to set up the system of equations.

1. Total weight equation:

The grocer wants to make a 10-pound mixture of peanuts and cashews. Since we are given that p represents the pounds of peanuts and c represents the pounds of cashews, we can write the equation:

p + c = 10

2. Cost equation:

The grocer wants to sell the mixture for $4.75 per pound. The cost of the peanuts is $4.00 per pound and the cost of cashews is $6.50 per pound. To calculate the total cost, we multiply the cost per pound by the weight of each component (peanuts and cashews) and sum them up. This can be expressed as:

4.00p + 6.50c = 4.75(10)

By setting up this system of equations, we can solve for the values of p and c, which represent the pounds of peanuts and cashews, respectively, that the grocer should use in order to make the 10-pound mixture.

The substance that has changed the most over time from its original plant material is the drug, opium. Opium is a narcotic substance obtained from the poppy plant and has been used as a painkiller for thousands of years. Over time, opium has undergone several transformations to become a more potent substance. The most significant change occurred when it was processed to produce morphine, a much stronger and more addictive substance. Morphine was first isolated from opium in 1804 by the German pharmacist Friedrich Sertürner. Since then, scientists have discovered how to further modify morphine to create an even more potent substance known as heroin.

Heroin is a highly addictive drug that has become a major public health problem. It is derived from morphine, which is derived from opium. The process of converting opium into heroin involves several chemical steps, which are illegal and extremely dangerous. This process often involves the use of toxic chemicals, such as hydrochloric acid and acetic anhydride, which can cause severe health problems and even death. Opium, morphine, and heroin are all examples of substances that have been changed significantly from their original plant material. However, the changes that have occurred over time have had serious consequences for public health and have led to a major epidemic of addiction and overdose deaths.

The driver allocated overtime is chosen at random.


What is the probability of you being allocated overtime next week? Give your answer as a fraction AND


a percentage.

Answers

In this case, there are 5 drivers and a probability of 1/4 (14/100) for overtime. Therefore, the probability of being allocated overtime next week is 1/20 or 5%.

Given that there are 5 drivers at Highfield Transport and the probability of overtime being available in any given week is 14/100, we can calculate the probability of being allocated overtime next week.

The probability of being allocated overtime is determined by the ratio of favorable outcomes (being allocated overtime) to the total possible outcomes (the number of drivers).

Favorable outcomes: There is only one driver who will be allocated overtime.

Total possible outcomes: There are 5 drivers in total.

Therefore, the probability of being allocated overtime is:

P(Overtime) = Favorable outcomes / Total possible outcomes

P(Overtime) = 1/5

This probability can also be expressed as a fraction, which is 1/5, or as a percentage, which is (1/5) * 100 = 20%.

Thus, the probability of being allocated overtime next week at Highfield Transport is 1/20 or 5%. This means that there is a 5% chance of being chosen for overtime among the 5 drivers.

Answers

To find the distance between the library and the firehouse in Adams, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the library and the firehouse form the two sides of a right triangle, with the school being the right angle. The distance between the library and the school is 16 kilometers (south) and the distance between the firehouse and the school is 12 kilometers (west).

Using the Pythagorean theorem, we can calculate the distance between the library and the firehouse:

[tex]Distance^2 = (Library-School Distance)^2 + (School-Firehouse Distance)^2[/tex]

[tex]Distance^2 = 16^2 + 12^2[/tex]

[tex]Distance^2 = 256 + 144[/tex]

[tex]Distance^2 = 400[/tex]

The pattern to the number series 5, 12, 26, ____, 110, 222 is 50.

How?

There are different methods to solve the pattern. For example, you can find the difference between consecutive numbers and check if it follows a pattern. Here, I am using this method to explain the answer. To start, we will find the difference between consecutive numbers.

5 to 12 = 7 (12 - 5 = 7)

12 to 26 = 14 (26 - 12 = 14)

26 to ____ = ?

____ to 110 = 84 (110 - ____ = 84)

110 to 222 = 112 (222 - 110 = 112)

Now, we will find the difference between the second difference.

7 to 14 = 7 (14 - 7 = 7)

14 to ____ = ?

____ to 84 = 70 (84 - ____ = 70)

84 to 112 = 28 (112 - 84 = 28)

Since we are given 5, 12, 26, ____, 110, 222

fill in the patterning blank, we need to find the blank space. So, let's work on that.

7 to 14 = 7 (14 - 7 = 7)

14 to ____ = ?

7 + 7 = 14

____ = 28 (14 + 14 = 28)

28 to 84 = 56 (84 - 28 = 56)

84 to 112 = 28 (112 - 84 = 28)

28 + 28 = 56

Hence, the blank in the patterning is 50. This number series has a pattern to solve. If you learn how to solve such patterns, you can easily find the blank in any patterning series. There are different methods to find the answer, as explained above, but the one I used is the most common one. Here, we found the difference between consecutive numbers and checked if it follows a pattern. The pattern we found is that the second difference is constant. The second difference is the difference between the first difference of the consecutive numbers. When we calculated the second difference, we found that the blank in the patterning series is 50. It means that the difference between 26 and the blank is 28, and the difference between the blank and 110 is 84.

(x^2+4x-43.61)

Limit -----------------------

(x^2-0.2x-23.03)

----> 4.9

Answers

The limit of the expression (x^2+4x-43.61)/(x^2-0.2x-23.03) as x approaches 4.9 is equal to a specific value. The limit of the given expression as x approaches 4.9 is approximately 1.51.

To find the limit as x approaches 4.9, we substitute 4.9 into the expression and evaluate it. Plugging in 4.9 for x, we get ((4.9)^2 + 4(4.9) - 43.61)/((4.9)^2 - 0.2(4.9) - 23.03). Simplifying this expression gives us (24.01 + 19.6 - 43.61)/(24.01 - 0.98 - 23.03), which further simplifies to 0/0.

When we encounter an indeterminate form like 0/0, we can apply mathematical techniques to evaluate the limit. One approach is to use L'Hôpital's Rule, which states that if the limit of the ratio of two functions f(x)/g(x) is of the form 0/0 or ∞/∞ as x approaches a certain value, then the limit of the ratio is equal to the limit of the derivative of f(x) divided by the derivative of g(x) as x approaches the same value.

In this case, we can differentiate the numerator and denominator separately and apply L'Hôpital's Rule. After differentiating, we obtain the new expression (2x + 4)/(2x - 0.2). Evaluating this expression at x = 4.9 gives us (2(4.9) + 4)/(2(4.9) - 0.2), which simplifies to 14.8/9.8. Therefore, the limit of the given expression as x approaches 4.9 is approximately 1.51.

What is the diameter of a hemisphere with a volume of 2507 inº, to the


nearest tenth of an inch?

Answers

The diameter of a hemisphere with a volume of 2507 in³, to the nearest tenth of an inch, is approximately 18.7 inches.

The volume of a hemisphere is given by the formula V = (2/3)πr³, where V represents the volume and r is the radius. Since we need to find the diameter, we know that the diameter is twice the radius. Rearranging the formula, we have r = (∛(3V/2π)).

Substituting the given volume of 2507 in³ into the formula, we get r = (∛(3 * 2507 / (2π))) ≈ 7.302. To find the diameter, we multiply the radius by 2: d ≈ 2 * 7.302 ≈ 14.604 inches. Rounding to the nearest tenth of an inch, the diameter of the hemisphere is approximately 14.6 inches.

However, it's important to note that there seems to be an inconsistency in the given volume unit, as "inº" does not represent a standard volume unit.

A construction manager weighs a pallet that has 9 identical bricks and a 7-pound concrete block on it. The pallet weighs 25 pounds.

Answers

Given that a construction manager weighs a pallet that has 9 identical bricks and a 7-pound concrete block on it. The pallet weighs 25 pounds.

Let the weight of each brick be 'x'. As per the question, the weight of the pallet along with 9 identical bricks and a 7-pound concrete block is 25 pounds.

Therefore, the total weight of the pallet with 9 bricks and a 7-pound concrete block is: P = Weight of the pallet + (Weight of 9 bricks) + (Weight of the concrete block) P = Weight of the pallet + (9 × x) + 7P = 25

On substituting the given values,

we have 25 = Weight of the pallet + (9 × x) + 7⇒ Weight of the pallet = 25 - 9x - 7⇒ Weight of the pallet = 18 - 9x

On the other hand, we know that Weight of the pallet = (Weight of the pallet) + (Weight of the 9 bricks).

Weight of the pallet = 18 - 9x Weight of the 9 bricks = 9x

Therefore, Weight of the pallet + Weight of the 9 bricks = 25⇒ (18 - 9x) + 9x

= 25⇒ 18 - x

= 25⇒ -x

= 25 - 18 ⇒ -x

= 7⇒ x =

-7/-1⇒ x = 7

Hence, each brick weighs 7 pounds.

A truck rental company rents a truck for a one-time fee of $25 plus $1. 50 per mile traveled. Kelly has $80 she can spend on the rental truck. Written as a fraction, what is the greatest number of miles that she can travel?.

Answers

To determine the greatest number of miles Kelly can travel with her $80 budget, we need to calculate the maximum number of miles she can afford based on the rental cost per mile.

Using the given information that the rental fee is $25 plus $1.50 per mile, we can set up an equation and solve for the number of miles.

Let's denote the number of miles traveled as 'm'. The total cost of renting the truck can be expressed as the sum of the one-time fee and the cost per mile: $25 + $1.50m.

Since Kelly has a budget of $80, we can set up an equation: $25 + $1.50m ≤ $80. To find the maximum number of miles, we need to solve this inequality for 'm'.

Subtracting $25 from both sides of the inequality gives: $1.50m ≤ $55.

To isolate 'm', we divide both sides of the inequality by $1.50: m ≤ 36.66.

Since we cannot have a fraction of a mile, the maximum number of miles Kelly can travel is 36 miles.

Answers

The inner height of the culvert, given the outer height and the outer width, would be 105 cm.

How to find the inner height ?

The culvert is essentially a rectangular structure, and the thickness affects both the height and the width.

To calculate the inner height of the culvert, you subtract twice the thickness of the culvert from the outer height, because the thickness is taken off from both the top and the bottom of the culvert.

Inner height = Outer height - 2 x (Thickness)

= 135 cm - 2 x 15 cm

= 135 cm - 30 cm

= 105 cm

A cylindrical garbage can of depth 3 ft and radius 1 ft fillswith rainwater up to a depth of 2 ft. Howmuch work would be done in pumping the water up to the top edge of the can

Answers

The amount of work that would be done by pumping water up to the top edge of the can would be 784.14 ft-lbs.

How to find the work done ?

The work done to pump water depends on both the weight of the water and the distance it's moved. The weight of the water is its volume times its density, and the density of water is about 62.4 lbs/ft³.

To find the total work, we add up (integrate) the work done on each piece of water, from the top of the water (x=1 ft) to the bottom of the water (x=3 ft):

W = ∫ (from x = 1 to x = 3) of 62. 4π xdx = 62.4π x [1/2x²] (from x=1 to x=3)

= 62.4π x (1/23² - 1/21²)

= 62.4π x (1/2*9 - 1/2)

= 62.4π x (4.5 - 0.5)

= 62.4π x 4

= 249.6π ft-lbs

How did Hamilton have the better vision for America

Answers

Alexander Hamilton was a staunch supporter of the Federalist Party and, in particular, a strong supporter of a powerful central government. He opposed Thomas Jefferson's philosophy of a strict interpretation of the Constitution and advocated for the creation of a strong economy, and the promotion of manufacturing and industry.

Their visions differed. Hamilton had a vision for America that was far more centralized and industrialized than that of Jefferson. He wanted a strong national government that would be able to support a thriving economy by promoting industry, commerce, and manufacturing, while Jefferson favored a limited federal government that would be unable to interfere in the lives of individual citizens.In Hamilton's view, the United States needed to establish itself as a world power, and he believed that this could be accomplished through a strong military and a powerful economy.

He saw the United States as a great commercial and manufacturing nation, and he believed that it could only achieve this status by embracing industrialization and creating a national bank that would provide the capital necessary to finance economic growth. Jefferson, on the other hand, believed that the federal government should have only limited powers and that these powers should be strictly defined by the Constitution. He believed that the states should have more power than the federal government and that the country should be primarily agrarian.

A coordinate grid is placed over a map. City A is located at (3,8) and a city B is located at (-3,20). If city C is halfway between city A and city B, find the distance between city A and city C to the nearest 2 decimal digits.

Answers

To find the distance between City A and City C, we need to calculate the midpoint between the coordinates of City A and City B.

Given:

City A: (3, 8)

City B: (-3, 20)

To find the midpoint between City A and City B, we can use the midpoint formula:

Midpoint = [(x1 + x2) / 2, (y1 + y2) / 2]

Applying the formula:

Midpoint = [(3 + (-3)) / 2, (8 + 20) / 2]

Midpoint = [0 / 2, 28 / 2]

Midpoint = [0, 14]

So, the coordinates of City C are (0, 14).

Now, to calculate the distance between City A and City C, we can use the distance formula:

Distance = √[(x2 - x1)^2 + (y2 - y1)^2]

Applying the formula:

Distance = √[(0 - 3)^2 + (14 - 8)^2]

Distance = √[(-3)^2 + 6^2]

Distance = √[9 + 36]

Distance = √45

Distance ≈ 6.71 (rounded to two decimal places)

Therefore, the distance between City A and City C is approximately 6.71 units.

A. How many miles per gallon does Joseph’s car run on?


_________ miles per gallon


B. If gasoline cost $2. 02 per gallon, how much would it cost to refill Joseph’s tank on Friday?


It would cost $_________

Answers



Joseph's car holds 16 gallons of gas and has driven 68 miles, resulting in a remaining tank level of 12 gallons. Joseph's car runs on 17 miles per gallon, and it would cost $8.08 to refill his tank on Friday.

To determine the car's miles per gallon (MPG), we divide the total miles driven by the number of gallons used. Additionally, we can calculate the cost of refilling Joseph's tank by multiplying the price per gallon by the number of gallons needed to reach a full tank.

To find the car's miles per gallon (MPG), we divide the total miles driven (68) by the number of gallons used (16 - 12 = 4). Therefore, the car runs on 68/4 = 17 miles per gallon.

Next, we calculate the cost to refill Joseph's tank on Friday. Since the tank holds 16 gallons and currently has 12 gallons, we need to fill it with 16 - 12 = 4 gallons. Given that gasoline costs $2.02 per gallon, the total cost to refill the tank is 4 * $2.02 = $8.08.

Therefore, Joseph's car runs on 17 miles per gallon, and it would cost $8.08 to refill his tank on Friday.

26) An NCAA basketball court has a length of


94 feet and a width of 50 feet, and an area


of 4700 square feet. A school plans to


make a smiliar court with the width of 45


feet. Find the area of both courts.

Answers

The area of the NCAA basketball court is 4700 square feet and the area of the similar court is 5142.78 square feet.

Given the length and width of an NCAA basketball court are 94 feet and 50 feet respectively, and it has an area of 4700 square feet.

The school plans to make a similar court with the width of 45 feet. We need to find the area of both courts. Let's begin by finding the area of the NCAA basketball court.

Area of the NCAA basketball court = Length x Width= 94 feet x 50 feet= 4700 square feet. Given the width of the similar court is 45 feet. Width of the NCAA basketball court = 50 feet. Width of the similar court = 45 feet. We need to find the length of the similar court.

The length of the similar court can be obtained using the proportion method.

Area of the NCAA basketball court / Area of the similar court = 1. Let the length of the similar court be "x". Area of the NCAA basketball court / Area of the similar court = (Length of the NCAA basketball court / Length of the similar court)²Area of the similar court = Area of the NCAA basketball court × (Length of the similar court / Length of the NCAA basketball court)².

Area of the similar court = 4700 × (x / 94)²

Area of the similar court = (4700 x²) / 94²

Area of the similar court = (4700 x²) / 8836

We know the width of the similar court is 45 feet. Area of the similar court

= Length x Width(4700 x²) / 8836

= x × 45x = (4700 x²) / (8836 x 45)x

= 470000 / (8836 x 45)x

= 114.284 ft.

Therefore, the length of the similar court is 114.284 ft. Area of the similar court =

Length × Width. Area of the similar court = 114.284 ft × 45 ft.

Area of the similar court = 5142.78 square feet.

The area of the NCAA basketball court is 4700 square feet and the area of the similar court is 5142.78 square feet.
