Hope this helped!

Step-by-step explanation:

The solution of the initial value problem xy' + y = 8e is equal to

log (x ) =  - log ( 8e - y ) .

Solution of the initial value problem is:

xy' + y = 8e

⇒ x (dy /dx ) + y = 8e

⇒ x (dy/dx ) = 8e -y

⇒  dx / x  = ( 1 / (8e -y ) ) dy

Integrate both the sides we get,

⇒ log (x ) =  - log ( 8e - y ) + c  ____(1)

Now , we have y ( 1 ) = -1 + 8e

Substitute the value  y ( 1 ) = -1 + 8e in (1) we get,

⇒ log ( 1 ) = - log ( 8e - ( -1 + 8e )) + c               ( value of log (1) = 0 )

⇒ 0 = - log ( 8e + 1 - 8e ) + c

⇒ 0 = log ( 1 ) + c

⇒ c = 0

Now substitute c =0 in (1) we get,

log (x ) =  - log ( 8e - y )

Therefore, the explicit solution of the initial value problem is equal to

log (x ) =  - log ( 8e - y ) .

The answers are k = 12√2 and [tex]\theta=\frac{\pi }{2}+2\pi n[/tex]

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Given are questions related to trigonometric functions:

a) k cos² (π/6) - k sin² (π/6) = 6√2

Finding k,

k cos² (π/6) - k sin² (π/6) = 6√2

Taking k common,

k [cos² (π/6) - sin² (π/6)] = 6√2

Since, cos²x-sin²x = cos2x

Therefore,

k[cos2(π/6)] = 6√2

k[cos(π/3)] = 6√2

Since, cos(π/3) = cos 60° = 1/2

Therefore,

k[1/2] = 6√2

k = 6√2 × 2

k = 12√2

b) sinx / cscx+cotx

[tex]\frac{sinx}{cscx+cotx}= \frac{sinx}{\frac{1}{sinx}+\frac{cosx}{sinx}}= \frac{sinx}{\frac{1+cosx}{sinx}}= \frac{sin^2x}{1+cosx}= \frac{1-cos^2x}{1+cosx}= \frac{(1+cosx)(1-cosx)}{1+cosx}\\\\= 1-cosx[/tex]

Answer:

The width of the rectangle is 9

Step-by-step explanation:

l + l + w + w = perimeter

(x - 8) + (x - 8) + (x) + (x) = 52  

We don't know the length so put it as a variable

x + x + x + x - 8 - 8 = 52         Group together like-terms.

4x - 16 = 52                            Combine like-terms                  

4x = 68                                  Add 16 to both sides

x  =   17                                Divide both sides by 4

We now have the value for the length (x = 17) however we need the value for the width. Just subtract 17 - 8 since the width is 8 in. less than its length.

17 + 17 + 9 + 9 = 52

Answer:

I think so.

Step-by-step explanation:

To calculate the total cost of the fence, we need to know the length of the fence.

In a right-angled triangle, the length of the fence can be calculated using the Pythagorean theorem, which states that the length of the hypotenuse (the fence) is equal to the square root of the sum of the squares of the other two sides (the base and the height of the triangle).

So, the length of the fence (C) = square root of (A^2 + B^2), where A is the base and B is the height of the triangle.

If the base of the triangle is x and the height of the triangle is y, then the cost of the fence can be calculated using the formula:

Cost = (length of fence) x (cost per meter)

Cost = (square root of (x^2 + y^2)) x 1.26

In order to calculate the cost, the farmer needs to know the values of x and y.

The total cost of the triangular shaped fence is A = £ 530

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of side AB = 145 m

Now , the measure of ∠BAC = 59°

From the trigonometric relations

tan θ = opposite / adjacent

tan 59° = BC / 145

Multiply by BC on both sides , we get

BC = 241.320524941 m

Now , the hypotenuse of the triangle is

H = √ ( 145 )² + ( 241.320524941 )²

H = √ ( 21,025 + 58,235.595757

H = √79,260.595757

H = 281.53258 m

Now , the total perimeter of triangle is P = 281.53258 + 241.320524941 + 145

P = 667.85310877 m

Now , fence costs £1.26 per meter

A = 667.85310877 m / £1.26

So , the total cost is A = £ 530

Hence , the total cost is A = £ 530

Brandi needs to receive a score of 46 on the final to have an average score of 80.

Step-by-step explanation:

First, let's understand what is being told to us. We are being asked to find the score Brandi needs on the final, or x. Since the final is worth 2 tests, the final is equal to twice the score she receives, or 2x. Next, we need the average of all the tests, including the final, to be equal to 80. It's important to also note that we will be taking the average of 6 scores. Now, let's use all of our information to write an equation to solve:

( 79 + 80 + 74 + 63 + 92 + 2x ) / 6 = 80.   [Combine like terms]

( 388 + 2x ) / 6 = 80   [Multiply by 6]

388 + 2x = 480   [Subtract 388 from both sides]

2x = 92   [Divide both sides by 2]

x = 46

So, Brandi needs to receive a score of 46 on the final to have an average score of 80.

The mean and standard deviation of the sampling distribution of the sample mean (average) of the SAT math scores are:

(b) Mean = 515, SD = 114/√100

The mean of the sampling distribution of the sample mean is equal to the population mean (515), because the expected value of the sample mean is equal to the population mean. The standard deviation of the sampling distribution of the sample mean is called the standard error, and it is equal to the population standard deviation divided by the square root of the sample size (114/√100).

The result (b) is determined based on the central limit theorem, which states that as the sample size increases, the distribution of the sample mean approaches a normal distribution with mean equal to the population mean and standard deviation equal to the population standard deviation divided by the square root of the sample size.

In this case, the population mean is 515 and the population standard deviation is 114, so the standard deviation of the sampling distribution of the sample mean is equal to 114/√100. This result can be mathematically proven using the formula for the standard deviation of the sample mean:

SD of sample mean = σ/√n, where σ is the population standard deviation and n is the sample size.

For Given Fraction 5/3, The total number of votes is 7648.

What is a fraction?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.

For example, 5/10 is a fraction.

Here, 5 is a numerator and 10 is a denominator.

There are four different types of fractions. They are:

Unit Fraction – In a fraction, the numerator with 1 is called a unit fraction. For example, ½, ¼

Proper Fraction – If a numerator value is less than the denominator value, it is called a proper fraction. Example: 7/9, 8/10

Improper Fraction – If a numerator value is greater than the denominator value, then it is called an improper fraction. Example: 6/5, 11/10

Mixed Fraction – If a fraction consists of a whole number with a proper fraction, it is called a mixed fraction. Example 5 ¾, 10 ½

Now,

As given ratio is 5/3 for Yes votes to no votes

so total votes is 5x+38x

The height of the tower is 600 feet

What is angle of elevation and the angle of depression?

Angle of elevation: The angle of elevation is the angle produced by the line of sight with the horizontal when the item is above the horizontal level.

Angle of depression: The angle of depression is the angle produced by the line of sight with the horizontal when the item is below the horizontal level.

Let's call the height of the tower "h".

Using trigonometry, we can set up equations based on the angles of elevation and depression:

tan 38° = h / 300

tan 29° = (h - 300) / 300

Solving for h,

h = 300 * tan 38°

h = 300 * 0.8192

h = 245.76

Now,

300 * tan 29° = (h - 300) / 300

300 * 0.5672 = (h - 300) / 300

h - 300 = 300 * 0.5672 / 0.5672

h - 300 = 300

h = 600

The amount of taxes collected is proportional to the population, so if the population increased by 3 million - 2 million = 1 million, the amount of taxes collected should increase by the same factor.

So, in 2017, 4 billion * (3 million / 2 million) = 6 billion dollars in taxes were collected.

Answer:

Since the amount of taxes collected is proportional to the population of the city, we can write the relationship between the amount of taxes and the population as:

T = kP

where T is the amount of taxes, P is the population, and k is the constant of proportionality.

From the information given, we can find the value of k:

4 billion = k * 2 million

k = 4 billion / 2 million = 2

So, for the population of 3 million in 2017, the amount of taxes collected would be:

T = k * P = 2 * 3 million = 6 billion

So, in 2017 the city collected 6 billion dollars in taxes.
