Suppose a city with 400,000 population has been growing at a rate of ​4% per year. If this rate​ continues, find the population of this city in 17 years

Answers

The population of a city with 400,000 population growing at a rate of 4% per year can be calculated using the following formula:
P​(t) = P​0 ​ (1 + r)​t
Where P​0 is the initial population, r is the growth rate, and t is the number of years the growth is applied.
In this example, the initial population is 400,000, the growth rate is 0.04, and t is 17 years. Applying this formula, we get:
P(17) = 400,000 (1 + 0.04)17
P(17) = 615,288
Therefore, the population of this city in 17 years will be 615,288 if the growth rate of 4% per year continues.

Find the standard matrix of the linear transformation T: R2 to R2 that reflects each vector through the line x1=-x2.

Answers

The standard matrix is:


| 0      -1 |
| -1      0 |

The standard matrix of the linear transformation T: R2 to R2 that reflects each vector through the line x1=-x2 can be found by following these steps:

1. Start with the standard basis vectors for R2, which are (1,0) and (0,1).


2. Apply the transformation T to each of these vectors to find the new vectors. For the first vector, (1,0), we have x1=1 and x2=0. The reflection through the line x1=-x2 gives us a new vector with x1=-x2=-0=0 and x2=-x1=-1. So the new vector is (0,-1).


3. For the second vector, (0,1), we have x1=0 and x2=1. The reflection through the line x1=-x2 gives us a new vector with x1=-x2=-1 and x2=-x1=-0=0. So the new vector is (-1,0).


4. The standard matrix of the transformation T is the matrix whose columns are the new vectors we found. So the standard matrix is:
```
| 0 -1 |
| -1  0 |
```
This is the standard matrix of the linear transformation T: R2 to R2 that reflects each vector through the line x1=-x2.

for the following two sequences (i) give the first 5 terms of the sequence. (ii) determine if the sequence converges or diverges. if the sequence converges, determine the limit of the sequence

Answers

The sequences can converge to 0 and also diverge towards infinity.

The two sequences are not mentioned in the question. Please provide the two sequences so that I can give you the first 5 terms of each sequence and determine if each sequence converges or diverges.

To find the first 5 terms of a sequence, you need to use the formula given for the sequence and plug in the values for the first 5 terms. For example, if the sequence is given by a_n = 2n + 1, the first 5 terms would be a_1 = 2(1) + 1 = 3, a_2 = 2(2) + 1 = 5, a_3 = 2(3) + 1 = 7, a_4 = 2(4) + 1 = 9, and a_5 = 2(5) + 1 = 11.

To determine if a sequence converges or diverges, you need to find the limit of the sequence as n approaches infinity. If the limit exists, then the sequence converges to that limit. If the limit does not exist, then the sequence diverges.

For example, the sequence a_n = 1/n converges to 0 as n approaches infinity, while the sequence a_n = n^2 diverges as n approaches infinity.

A discount store is selling 5 small tables with 8 chairs for $115. Three tables with 5 chairs cost $70.

Which system of linear equations could be used to find the cost of each table (x) and the cost of each chair (y)?

Determine the cost of each table (x) and the cost of each chair (y).

answer both question please and thank you

Answers

Using linear equations 5x + 8y = 115 and 3x + 5y = 70,  the cost of each table is $15 and the cost of each chair is $5.

What is a linear equation, exactly?

A linear equation is a mathematical expression that describes a straight line relationship between two variables. It can be written in the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept.

Now,

Let x = cost of each table and y= cost of each chair. Then, we can set up the following system of linear equations based on the given information:

5x + 8y = 115 (equation 1)

3x + 5y = 70 (equation 2)

Equation 1 represents the cost of 5 small tables with 8 chairs, and equation 2 represents the cost of 3 tables with 5 chairs.

Now,

Solve equation 2 for x:

3x + 5y = 70

3x = 70 - 5y

x = (70 - 5y)/3

Substitute x into equation 1:

5x + 8y = 115

5[(70 - 5y)/3] + 8y = 115

Simplify and solve for y:

350/3 - 25/3 y + 8y = 115

23/3 y = 115 - 350/3

y = 5

Substitute y = 5 into equation 2 and solve for x:

3x + 5y = 70

3x + 5(5) = 70

3x = 45

x = 15

Therefore,

               the cost of each table is $15 and the cost of each chair is $5.

what is the multiplier for 1%, and 2% decay?​

Answers

"The multiplier for decay is given by the formula:

multiplier = (1 - (decay rate/100))^n

where "decay rate" is the percentage rate of decay per time period (usually per year), and "n" is the number of time periods.

For a decay rate of 1%, the multiplier would be:

multiplier = (1 - (1/100))^n = 0.99^n

For a decay rate of 2%, the multiplier would be:

multiplier = (1 - (2/100))^n = 0.98^n

The value of the multiplier depends on the number of time periods "n". For example, if we want to find the value of an initial quantity after 3 years of 1% decay, we would use the multiplier of 0.99 raised to the power of 3:

multiplier = 0.99^3 = 0.9703

This means that the final quantity would be 97.03% of the initial quantity.

Similarly, if we want to find the value of an initial quantity after 5 years of 2% decay, we would use the multiplier of 0.98 raised to the power of 5:

multiplier = 0.98^5 = 0.9039

This means that the final quantity would be 90.39% of the initial quantity." (ChatGPT, 2023)

The diagonal of rectangle is 26 and its perimeter is 68 what are its dimensions

Answers

If the diagonal of the rectangle is 26 and its perimeter is 68, its dimensions are either 24 by 10 or 10 by 24.

Let's denote the length and width of the rectangle as L and W, respectively.

We know that the diagonal of the rectangle is 26, which we can express using the Pythagorean theorem:

[tex]L^2[/tex]+ [tex]W^2[/tex]=[tex]26^2[/tex]

We also know that the perimeter of the rectangle is 68:

2L + 2W = 68

We can simplify the second equation by dividing both sides by 2:

L + W = 34

We can use this simplified equation to express one variable in terms of the other:

L = 34 - W

This is what we get when we enter it into the first equation:

[tex](34 - W)^2[/tex] + [tex]W^2[/tex] = [tex]26^2[/tex]

Expanding the square and simplifying, we get:

[tex]2W^2[/tex] - 68W + 420 = 0

Dividing both sides by 2, we get:

[tex]W^2[/tex]- 34W + 210 = 0

The quadratic formula can be used to find W:

W = (-b ± t[tex]\sqrt{(b^2 - 4ac)}[/tex] )/ 2a

where a = 1, b = -34, and c = 210. Plugging in these values, we get:

W = (34 ± [tex]\sqrt{34^2 - 4(1)(210))}[/tex]) / 2(1)

W = (34 ± [tex]\sqrt{196}[/tex]) / 2

W= (34 ± 14)/2

W = 17 ± 7

As the breadth cannot be negative, we can disregard the negative solution. Therefore, we have:

W = 24 or W = 10

If W = 24, then L = 10 (using L = 34 - W). If W = 10, then L = 24. Therefore, the dimensions of the rectangle are either 24 by 10 or 10 by 24.

The correct answer is experimental 22.5% theoretical 18.2%. To calculate the experimental probability of drawing the letter M, we must first identify the total number of items in the bag.

What is  theoretical probability?

The theoretical probability is the likelihood of the event to happen without conducting an experiment,

The total number of items in the bag is 9 + 12 + 7 + 2 + 4 + 1 + 3 + 2 = 40. Next, we divide the number of items with the letter M (9) by the total number of items to get the experimental probability of drawing the letter M.

Therefore, 9/40 = 0.225

= 22.5%.  

To calculate the theoretical probability of drawing the letter M, we must first identify the total number of letters in the bag.

There are 8 letters in the bag (M, A, T, H, E, I, C, S).

b. How many of the 9 inch by 9 inch tiles will it take to cover the floor? (NOTE: You

will need to convert the area in Part a from square feet to square inches.)

c. If the tile is sold only in boxes of 12 tiles per box, how many boxes will Mr. Dieter

have to buy to tile the family room?

Answers

a. The area of the family room is 162 ft².

b. 24 tiles will be needed to cover the floor.

c. Mr. Dieter will have to buy 2 boxes to tile the family room.

The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

All real numbers are thought to be sufficiently described by the four basic operations, also referred to as "arithmetic operations." The mathematical operations quotient, product, sum, and difference come after division, multiplication, addition, and subtraction.

a. There are two different shapes of which one is rectangle and other is triangle.

So,

⇒ Area of rectangle = length x width

⇒ Area of rectangle = 16 x 8

⇒ Area of rectangle = 128 ft²

Also,

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x base x height

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x 4 x 3

⇒ Area of first triangle = 6 ft²

Similarly,

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x base x height

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x 8 x 7

⇒ Area of first triangle = 28 ft²

On adding the three areas, we get

⇒ Area of family room = 128 + 6 + 28

⇒ Area of family room = 162 ft²

b. We will convert the area into inches.

We know that 1 feet = 12 inches.

So, using the multiplication, we get

162 feet = 162 * 12 in²

162 feet = 1944 in²

Now,

⇒ Area of tile = 9 * 9

⇒ Area of tile = 81 in²

So,

⇒ Number of tiles = [tex]\frac{1944}{81}[/tex]

⇒ Number of tiles = 24

c. Since, tiles are sold in boxes of 12 so, using the division operation, we get

⇒ Number of boxes needed = [tex]\frac{24}{12}[/tex]

⇒ Number of boxes needed = 2

Hence, the required solution has been obtained.

Solve triangle ABC given that A = 56°, B = 57°, and b = 9. 0. Round the length of the sides to the nearest hundredth.

Answers

The sides of the triangle to the nearest hundredth are: a ≈ 8.99, b ≈ 7.96

and c ≈ 9.44.

To solve the triangle, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides.

Using this law, we can find the length of side a as follows:

sin A / a = sin B / b

sin 56° / a = sin 57° / 9

a = 9 * sin 56° / sin 57°

a ≈ 8.99

Similarly, we can find the length of side c as follows:

sin C / c = sin B / b sin (180° - A - B) / c = sin 57° / 9

sin 67° / c = sin 57° / 9

c = 9 * sin 67° / sin 57°

c ≈ 9.44

Now, we can use the Law of Cosines to find the length of the remaining side, side b:

b 2 = a 2 + c 2 - 2ac cos B

b 2 = (8.99) 2 + (9.44) 2 - 2(8.99)(9.44) cos 57°

What is a function?

A mathematical notion known as a function explains the connection between two sets of values known as the domain and the range. A function takes a value from the domain as an input, applies some logic to it, and returns a value in the range. Just one output value in the range corresponds to each input value in the domain. Functions can be described verbally or with mathematical symbols. They are employed throughout the mathematical discipline as well as in the sciences of physics, engineering, economics, and computer science.

The given function is f(x) = 2(x - 4)³ + 7.

Swap the variables, that is substitute x = y and vice versa as follows:

x = 2(y - 4)³ + 7

x - 7 = 2(y - 4)³

(x - 7) / 2 = (y - 4)³

Taking the cube root of both sides gives:

y - 4 = ∛[(x - 7) / 2]

y = ∛[(x - 7) / 2] + 4

A translation rule is a mathematical description of how to move each point in a geometric shape by a fixed distance in a certain direction. It is used to describe a transformation called a translation, which moves a shape without changing its size, shape, or orientation.

To find the composition of the two translation rules, we apply the second rule first and then apply the first rule to the result.

Let's consider a point (x, y). Applying the second rule (x, y) → (x - 5, y - 5) gives us a new point:

Claire buys furniture to the value of R35 000. she pays a 15% cash deposit and signs a hire purchase agreement for the balance. the interest rate will be 13% per annum and she will pay off the loan over a period of 3 years. what is the value of the deposit?​

Answers

Answer:

Total amount = R41 337.50

Step-by-step explanation:

The value of the deposit is 15% of the total purchase price:

Deposit = 15/100 x R35 000

Deposit = R5 250

To calculate the balance that Claire will have to pay off, we need to subtract the deposit from the total purchase price:

Balance = Total purchase price - Deposit

Balance = R35 000 - R5 250

Balance = R29 750

To calculate the interest that Claire will have to pay on the balance, we can use the formula:

Interest = Principal x Rate x Time

where:

Principal is the amount of the balance

Rate is the annual interest rate (13%)

Time is the duration of the loan in years (3)

So, the interest that Claire will have to pay is:

Interest = R29 750 x 0.13 x 3

Interest = R11 587.50

Therefore, the total amount that Claire will have to pay back over the 3-year period is:

Total amount = Balance + Interest

Total amount = R29 750 + R11 587.50

Total amount = R41 337.50

Note that this assumes that the interest is calculated annually and added to the balance at the end of each year. In reality, the interest may be calculated differently depending on the terms of the hire purchase agreement.

Triangle a′b′c′ is a dilation of ​triangle abc​ about point p with a scale factor of 12. is the dilation a reduction or an enlargement? responses reduction reduction enlargement

Answers

The dilation of triangle ABC about point P with a scale factor of 12 is an enlargement.

In a dilation, the size of a figure is changed by multiplying its dimensions by a scale factor. If the scale factor is greater than 1, the figure is enlarged. If the scale factor is between 0 and 1, the figure is reduced in size. In this case, the scale factor is 12, which is greater than 1. Therefore, triangle ABC is enlarged to form triangle A'B'C' by a factor of 12. Therefore, the dilation is an enlargement.

In the context of triangles, an enlargement means that all sides and angles of the original triangle are increased by the same factor to create a larger triangle. In this case, the sides and angles of triangle ABC are multiplied by a factor of 12 to create triangle A'B'C'. As a result, the corresponding sides and angles of the two triangles are proportional, but the enlarged triangle is 12 times larger than the original triangle.

The relationship between the number of decibels β and the intensity of a sound I
in watts per square meter is
β=10log(I10−12)
(a) Determine the number of decibels of a sound with an intensity of 1 watt per square meter.
(b) Determine the number of decibels of a sound with an intensity of 10−2
watt per square meter.
(c) The intensity of the sound in part (a) is 100 times as great as that in part (b). Is the number of decibels 100 times as great? Explain.

Answers

(a) A sound with an intensity of 1 watt per square meter has a decibel level of -120.

(b) A sound with an intensity of 10⁻² watt per square meter has a decibel level of -140.

(c) The number of decibels is not 100 times as great as the intensity, even though the intensity in part (a) is 100 times greater than the intensity in part (b).

What is the sound level?

Using the relationship of intensity of sound and number of decibels, we can calculated the required number of decibels as follows;

β =10 log(I x 10⁻¹²)

(a) Decibel level: plugging in I = 1 watt per square meter into the equation, we get:

β = 10 log(1 x 10⁻¹²) = 10 log(10⁻¹²) = -120 decibels

(b) Decibel level: plugging in I = 10⁻² watt per square meter into the equation, we get:

β = 10 log(10⁻² x 10⁻¹²) = 10 log(10⁻¹⁴) = -140 decibels

(c) Let's calculate the decibel level for the sound in part (a) using the given formula:

β₁ = 10 log(I₁ x 10⁻¹²) = 10 log(100 x I₂ x 10⁻¹²) = 10 log(I₂ x 10⁻¹⁴) + 20

where;

I₂ is the intensity of the sound in part (b).

Using the result from part (b), we can substitute I₂ = 10⁻² watt per square meter and get:

β₁ = -140 + 20 = -120 decibels

Comparing this result to the decibel level for the sound in part (a) (which is also -120 decibels), we see that they are the same.

In the triangle, the values are p=10.3, [tex]\angle Q=19.5\textdegree[/tex] and [tex]\angle R = 112.5\textdegree[/tex].

What is trigοnοmetric functiοn?

The functiοns οf an angle in a triangle are knοwn as trigοnοmetric functiοns, cοmmοnly referred tο as circular functiοns. In οther wοrds, these trig functiοns prοvide the relatiοnship between a triangle's angles and sides. There are five fundamental trigοnοmetric functiοns: sine, cοsine, tangent, cοtangent, secant, and cοsecant.

Here in the given triangle PQR, [tex]\angle P = 48\textdegree[/tex] , q=5 and r=13.

Now using law of cosine fοrmula,

=> [tex]p^2=q^2+r^2-2qr.cos\angle P[/tex]

=> [tex]p^2=5^2+13^2-2.5.13.cos 48\textdegree[/tex]

=> [tex]p^2=25+169-130cos48\textdegree[/tex]

=> [tex]p^2=107[/tex]

=> p = 10.3

Now using law of sine then,

=> [tex]\frac{p}{sinP}=\frac{q}{sinQ}[/tex]

=> [tex]sinQ=\frac{q sinP}{p}[/tex]

=> [tex]sin Q= \frac{5sin 48\textdegree}{10.3}[/tex]

=> sin Q = 0.344

=>[tex]\angle Q = 19.5\textdegree[/tex]

Now sum οf all angles in triangle is 180°. Then,

=>[tex]\angle P+\angle Q+\angle R = 180\textdegree[/tex]

=> [tex]\angle R = 180-48-19.5=112.5\textdegree[/tex]

Hence the answers are p=10.3, [tex]\angle Q=19.5\textdegree[/tex] and [tex]\angle R = 112.5\textdegree[/tex].

3t-18=4(-3- 3/4t

solve for t

Answers

Answer:

t = 1

Step-by-step explanation:

I will assume that there is a parenthesis missing:  the equation should read 3t-18=4(-3- 3/4t) and not 3t-18=4(-3- 3/4t

3t-18=4(-3- 3/4t)

3t-18= -12- 12/4t   [Remove parentheses by multiplying each term by 4]

3t-6= - 3/t    [Simplify]

3t^2-6t = -3  [Multiply both sides by t]

3t^2-6t +3 = 0

3(t^2-2t+1)=0

3(t-1)*(t-1) = 0

Two solutions, both the same value:  

(t-1) = 0

t = 1

===

Does t=1 result in 0 for the equation?

3t-18=4(-3- 3/4t)

3(1)-18=4(-3- 3/4*(1))

3-18 = 4(-3-3/4)

(a) There are 101 integers between 50 and 150 (including 50 and 150 themselves). Out of these, 50 integers are two-digit numbers (50 to 99) and 51 integers are three-digit numbers (100 to 150). Therefore, it is slightly more likely to draw a three-digit number than a two-digit number.

(b) To find the number of integers between 50 and 150 that are multiples of 3, we can count the number of integers that leave a remainder of 0 when divided by 3. The first multiple of 3 in this range is 51 and the last multiple of 3 is 150, so there are (150-51)/3 + 1 = 34 multiples of 3 in this range.

To find the number of integers between 50 and 150 that are multiples of 5, we can count the number of integers that leave a remainder of 0 when divided by 5. The first multiple of 5 in this range is 50 and the last multiple of 5 is 150, so there are (150-50)/5 + 1 = 21 multiples of 5 in this range.

Therefore, it is more likely to draw a multiple of 3 than a multiple of 5 from the given range of consecutive integers.

Answer:

i think 150 is the answer

if 4x+y=7 is a true equation what would be the value of −5(4x+y)

Answers

Answer:

-32

Step-by-step explanation:

since 4x+y equals 7, multiply -5 by 7

Answer:

40x - 5y = -40x - 5(4x + y) = -40x - 20x - 5(7) = -60x - 35

Step-by-step explanation:

To find the value of -5(4x+y), we first need to simplify the expression inside the parentheses:

-5(4x + y) = -5(4x) - 5(y) = -20x - 5y

Now, we can substitute the value of y from the given equation:

-20x - 5y = -20x - 5(4x + y) = -20x - 20x - 5y = -40x - 5y

Since we know that 4x + y = 7, we can substitute this into the above equation:

-40x - 5y = -40x - 5(4x + y) = -40x - 20x - 5(7) = -60x - 35

The choking gas covered the town, quickly killing hundreds-including many children, who were less resistant to the gas than adults and forcing Bhopal's 670,000 inhabitants to flee in panic. By the end of the week more than 2,000 people had died from inhaling the gas, and 150,000 more had to be hospitalized for respiratory and eye damage, making Bhopal's 'night of death' the worst industrial disaster in history. Images of stunned families burying or burning their dead and blaming Union Carbide for their agony were broadcast worldwide. There were immediate repercussions for Union Carbide and for the chemical industry as well. The Indian government accused the plant management of failing to take adequate safety precautions and indicated that it held the parent company ultimately responsible. Lawsuits brought by American lawyers on behalf of the victims asked for billions of dollars in compensatory and punitive damages and threatened to send the company into bankruptcy. Union Carbide's stock price plummeted; it halted production of methyl isocyanate at its West Virginia plant that produced the chemical in the United States. Officials in the United States and India called for increased regulation and inspection of chemical processing plants. Many U.S. localities considered passing "right to-know" laws that would require chemical companies to provide detailed information about hazardous materials to the employees who make them and to residents living near the plants. Several companies countered with voluntary right- to-know programmes to head off public sentiment for government regulation. In the wake of protest against Union Carbide in other parts of the world, some multinational corporations claimed that the Bhopal disaster had chilled the international climate for U.S. business. Union Carbide, which had earned an above-average record on industrial safety over the decade or more preceding the disaster, appeared paralysed by the magnitude of Bhopal's suffering. Corporate chairman Warren Anderson, rushed to India to inspect the site and was briefly arrested by Indian authorities. Union Carbide's one hundred thousand employees observed a moment of silence for the dead and injured; many donated money for disaster relief. Top management spent sleepless nights grappling with the company's crushing problems and its uncertain future. Morale at the company was low; production at many plants temporarily dropped. However, while expressing profound sympathy for the Bhopal victims and promising to make a fair restitution, Union Carbide maintained its essential innocence. "There's no criminal responsibility here," said Anderson. (Source Courtesy: Stoner, Management VSP Rao, V Hari Krishna - Excel Books 2002) a Questions: 1.
