Please explain your answer to the question in the picture with steps.

The cylindrical coordinates of the point (4, 3, -3) are (5, 36.87°, -3).

To convert the point (x, y, z) = (4, 3, -3) to cylindrical coordinates (r, θ, z), we need to determine the magnitude of the radial distance (r), the angle (θ), and the height (z).

Magnitude of the radial distance (r):

The radial distance (r) can be found using the formula: r = sqrt(x^2 + y^2).

Plugging in the values, we have:

r = [tex]\sqrt{(4^2 + 3^2)}[/tex]

= [tex]\sqrt{16 + 9}[/tex]

= [tex]\sqrt{25}[/tex]

= 5

Angle (θ):

The angle (θ) can be found using the formula: θ = arctan(y / x).

Plugging in the values, we have:

θ = arctan(3 / 4)

To find the value of θ, we can use a calculator or trigonometric tables. In decimal form, we have:

θ ≈ 36.87°

Height (z):

The height (z) remains the same in cylindrical coordinates.

Putting it all together, the point (x, y, z) = (4, 3, -3) in cylindrical coordinates is represented as (r, θ, z) = (5, 36.87°, -3).

Sophia will drive a distance of 300 miles.

To find out how far Sophia will drive, we need to calculate 3/5 of the total trip distance of 500 miles.

1: Calculate the distance driven by Sophia

To find the distance driven by Sophia, we need to multiply the total trip distance by the fraction representing the portion she will drive. Sophia will drive the first 3/5 of the trip.

Distance driven by Sophia = (3/5) * 500 miles

2: Simplify the fraction

To calculate the distance, we simplify the fraction 3/5.

Distance driven by Sophia = (3/5) * 500 miles

                       = (3 * 500) / 5 miles

                       = 1500 / 5 miles

Factors such as scene size, complexity, evidence type, available resources, and time constraints determine the appropriate crime scene search pattern.

Determining the appropriate crime scene search pattern requires careful consideration of various factors to ensure a systematic and thorough search. While I cannot provide a calculation for this question since it involves subjective decision-making, I can provide a detailed explanation of the factors that should be taken into account when selecting a search pattern.

1. Size and nature of the crime scene: Consider the overall size and layout of the crime scene. Is it a small confined space or a large outdoor area? The size will influence the choice of search pattern. For smaller scenes, a line or grid search may be more suitable, while larger scenes may require a quadrant or zone search.

2. Type of evidence and scene complexity: Evaluate the type of evidence that may be present and the complexity of the scene. Are there specific areas or items of interest that require a focused search? Does the scene have multiple levels or rooms? A spiral search may be effective for scenes with a well-defined center, while a quadrant search allows for targeted searches in specific areas.

3. Number of investigators available: Assess the number of investigators available for the search. Different search patterns require different levels of manpower. For example, a grid search may require more personnel compared to a line search. Consider the available resources and allocate personnel accordingly.

4. Time constraints and urgency: Consider the urgency of the search and any time constraints. If there is a need for a rapid search, a line or spiral search may be more efficient. However, if time permits, a more detailed and thorough search, such as a grid or quadrant search, can be implemented.

5. Expert opinion and experience: Seek input from experienced crime scene investigators or forensic experts who can provide valuable insights and recommendations based on their expertise and prior experiences.

Ultimately, the choice of search pattern should be based on a careful assessment of these factors, combined with the investigator's professional judgment and experience. The goal is to conduct a methodical and comprehensive search to ensure all relevant evidence is discovered and properly documented.

A shirt is priced at $16, and a sweater carries a price tag of $33.

To solve this problem, we can set up a system of equations based on the given information. Let's represent the cost of a shirt as 's' and the cost of a sweater as 'w'.

From the first statement, Andrea is able to buy 3 shirts and 2 sweaters for $114. We can express this as the equation:

3s + 2w = 114.

From the second statement, Andrea is able to buy 2 shirts and 4 sweaters for $164. We can express this as the equation:

2s + 4w = 164.

To solve this system of equations, we can use the method of substitution or elimination. Here, let's use the substitution method.

First, let's solve the first equation for 's':

3s + 2w = 114

3s = 114 - 2w

s = (114 - 2w)/3.

Now, substitute the expression for 's' in the second equation:

2((114 - 2w)/3) + 4w = 164

(228 - 4w)/3 + 4w = 164

228 - 4w + 12w = 492

8w = 492 - 228

8w = 264

w = 264/8

w = 33.

Now, substitute the value of 'w' into the first equation to find the value of 's':

3s + 2(33) = 114

3s + 66 = 114

3s = 114 - 66

3s = 48

s = 48/3

s = 16.

Therefore, a shirt costs $16, and a sweater costs $33.

In summary, based on the given information and the solution to the system of equations, the cost of a shirt is $16, and the cost of a sweater is $33.

Answer:

1) x = 43.33

2) x =  tan⁻¹(4/3)  = 53.13

Step-by-step explanation:

1) Formula: cos(A) = sin(90 - A)

sin(2x - 30) = cos(x - 10)

⇒ sin(2x - 30) = sin(90 - (x - 10))

⇒ sin(2x - 30) = sin(90 - x + 10)

⇒ sin(2x - 30) = sin(100 - x)

⇒ 2x - 30 = 100 - x

⇒ 3x = 130

⇒ x = 130/3

x = 43.33

2) 4sinx . cosx - 3sin²x = 0

⇒ 4sinx . cosx = 3sin²x

⇒ 4cosx = 3sinx

⇒ [tex]\frac{4}{3} =\frac{sinx}{cosx}[/tex]

⇒ [tex]tan x = \frac{4}{3}[/tex]

⇒ x =  tan⁻¹(4/3)

⇒ x = 53.13

Answer:

[tex]\textsf{1)} \quad x \approx 43.33^{\circ}[/tex]

[tex]\textsf{2)} \quad \boxed{\begin{aligned}x &= \pi n \;\text{radians}\\x&=0.93+\pi n\; \text{radians}\end{aligned}}\quad \boxed{\begin{aligned}x &= 180^{\circ}n\\x&=53.13^{\circ}+180^{\circ} n\; \end{aligned}}[/tex]

Step-by-step explanation:

Given trigonometric equation:

[tex]\sin(2x - 30^{\circ}) = \cos(x - 10^{\circ})[/tex]

To solve the given trigonometric equation, we can use the following trigonometric identity:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Trigonometric identity} \\\\$\cos (\theta)=\sin(90^{\circ}-\theta)$\\\end{minipage}}[/tex]

Apply the trigonometric identity to the right side of the equation:

[tex]\begin{aligned}\sin(2x - 30^{\circ}) &= \cos(x - 10^{\circ})\\\\&= \sin(90^{\circ}-(x - 10^{\circ}))\\\\&= \sin(90^{\circ}-x +10^{\circ})\\\\&= \sin(100^{\circ}-x)\end{aligned}[/tex]

Since the sine function is equal, we can equate the angles:

[tex]2x - 30^{\circ}=100^{\circ}-x[/tex]

Now simplify and solve for x:

[tex]\begin{aligned}2x - 30^{\circ}&=100^{\circ}-x\\\\2x - 30^{\circ}+x&=100^{\circ}-x+x\\\\3x - 30^{\circ}&=100^{\circ}\\\\3x - 30^{\circ}+30^{\circ}&=100^{\circ}+30^{\circ}\\\\3x&=130^{\circ}\\\\\dfrac{3x}{3}&=\dfrac{130^{\circ}}{3}\\\\x&=\left(\dfrac{130}{3}\right)^{\circ}\\\\x&\approx 43.3^{\circ}\; \sf (nearest\;tenth)\end{aligned}[/tex]

Therefore, the solution to the equation sin(2x - 30°) = cos(x - 10°) is approximately x = 43.33°.

Given trigonometric equation:

[tex]4 \sin x \cos x-3\sin^2x=0[/tex]

Factor out the common term sin(x):

[tex]\sin x(4 \cos x-3\sin x)=0[/tex]

According to the zero product property, one of the factors must be equal to zero for the equation to hold.

Set each factor equal to zero and solve for x.

Factor 1

[tex]\sin x=0[/tex]

According to the unit circle, sin(x) = 0 when x = 0 and x = π.

As the sine function is periodic with a period of 2π, the solutions to sin(x) = 0 are:

[tex]x=0+2\pi n, \;\;x=\pi + 2\pi n[/tex]

Therefore, x is any multiple of π, where n is an integer:

[tex]\boxed{x = \pi n}[/tex]

Factor 2

[tex]\begin{aligned}4\cos x - 3 \sin x & = 0\\\\4 \cos x & = 3 \sin x\\\\\dfrac{4}{3}&=\dfrac{\sin x}{\cos x}\\\\\dfrac{4}{3}&=\tan x\\\\\implies x&=\arctan\left(\dfrac{4}{3}\right)\\\\x&=0.92729...\end{aligned}[/tex]

As the tangent function is periodic with a period of π, the solutions are:

[tex]\boxed{x=0.92729...+\pi n}[/tex]

where n is an integer.

Therefore, the solutions to the equation 4sin(x)cos(x) - 3sin²(x) = 0 are:

[tex]\boxed{\begin{aligned}x &= \pi n \;\text{radians}\\x&=0.93+\pi n\; \text{radians}\end{aligned}}[/tex]    [tex]\boxed{\begin{aligned}x &= 180^{\circ}n\\x&=53.13^{\circ}+180^{\circ} n\; \end{aligned}}[/tex]

(where n is an integer)

The expansion of the function [tex](3x - 4)^4[/tex] simplifies to [tex]81x^4 - 432x^3 + 864x^2 - 768x + 256.[/tex]

To expand the function [tex]f(x) = (3x - 4)^4[/tex], we can use the binomial theorem. According to the binomial theorem, for any real numbers a and b and a positive integer n, the expansion of [tex](a + b)^n[/tex] can be written as:

[tex](a + b)^n = C(n, 0)a^n b^0 + C(n, 1)a^{(n-1)} b^1 + C(n, 2)a^{(n-2)} b^2 + ... + C(n, n-1)a^1 b^{(n-1)} + C(n, n)a^0 b^n[/tex]

where C(n, k) represents the binomial coefficient, which is given by C(n, k) = n! / (k!(n-k)!).

Applying this formula to our function [tex]f(x) = (3x - 4)^4[/tex], we have:

[tex]f(x) = C(4, 0)(3x)^4 (-4)^0 + C(4, 1)(3x)^3 (-4)^1 + C(4, 2)(3x)^2 (-4)^2 + C(4, 3)(3x)^1 (-4)^3 + C(4, 4)(3x)^0 (-4)^4[/tex]

Simplifying each term, we get:

[tex]f(x) = 81x^4 + (-432x^3) + 864x^2 + (-768x) + 256[/tex]

Therefore, the expanded form of the function [tex]f(x) = (3x - 4)^4[/tex] is [tex]81x^4 - 432x^3 + 864x^2 - 768x + 256[/tex].

Note that the coefficient of [tex]x^3[/tex] is -432, the coefficient of [tex]x^2[/tex] is 864, the coefficient of x is -768, and the constant term is 256.

A) The slope between the points (0, -4) and (2, -1) is 1.5.

b)  the slope between the points (0, -4) and (4, -1) is 0.75.

c) The slope of 0.75 indicates that for every 1 unit increase in x, there is a 0.75 unit increase in y.

Part A: To calculate the slope between two points, we use the formula:

slope = (change in y) / (change in x)

Let's choose the points (0, -4) and (2, -1).

Change in y = -1 - (-4) = 3

Change in x = 2 - 0 = 2

slope = 3 / 2 = 1.5

Therefore, the slope between the points (0, -4) and (2, -1) is 1.5.

Part B: Let's choose different points from the table, such as (0, -4) and (4, -1).

Change in y = -1 - (-4) = 3

Change in x = 4 - 0 = 4

slope = 3 / 4 = 0.75

Thus, the slope between the points (0, -4) and (4, -1) is 0.75.

Part C: The slopes from parts A and B provide information about the relationship between the points.

In part A, where the slope was calculated as 1.5, we can see that as the x-values increase by 2 units, the y-values increase by 3 units. This suggests a positive relationship between the points, meaning that as x increases, y also increases. The slope of 1.5 indicates that for every 1 unit increase in x, there is a 1.5 unit increase in y.

In part B, where the slope was calculated as 0.75, we observe a similar positive relationship between the points. As the x-values increase by 4 units, the y-values increase by 3 units. The slope of 0.75 indicates that for every 1 unit increase in x, there is a 0.75 unit increase in y.

Overall, the positive slopes in both parts A and B suggest that the points on the table exhibit a positive linear relationship. This means that as x increases, y also increases, and the rate of change is consistent based on the slope.

To determine which set of side measurements could be used to form a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's evaluate each set of side measurements:

a. 12, 23, 7

In this case, the sum of the lengths of the two shorter sides (12 and 7) is 19, which is less than the length of the longest side (23). Therefore, this set of side measurements cannot form a triangle.

b. 10, 7, 2

Here, the sum of the two shorter sides (10 and 2) is 12, which is greater than the length of the longest side (7). This set of side measurements also fails to satisfy the triangle inequality theorem and cannot form a triangle.

c. 8, 3, 11

The sum of the two shorter sides (8 and 3) is 11, which is greater than the length of the longest side (11). Therefore, this set of side measurements can form a triangle.

d. 5, 11, 8

In this case, the sum of the lengths of the two shorter sides (5 and 8) is 13, which is greater than the length of the longest side (11). Hence, this set of side measurements can also form a triangle.

To find the surface area of square OABC, we calculate the side length using the coordinates of point B, resulting in 25/16 units.

To find the surface area of square OABC, we need to determine the length of one side of the square. Since point B lies on the line with the equation y = -4x + 5, we can use this information to find the coordinates of point B and then calculate the distance between points O and B to determine the side length.

First, we need to find the x-coordinate of point B. Since we know the equation of the line y = -4x + 5, we can substitute y = 0 (since point B lies on the x-axis) and solve for x:

0 = -4x + 5

4x = 5

x = 5/4

Therefore, the x-coordinate of point B is 5/4.

Next, we substitute this x-coordinate back into the equation y = -4x + 5 to find the y-coordinate of point B:

y = -4(5/4) + 5

y = -5 + 5

y = 0

So, the coordinates of point B are (5/4, 0).

Now, we can calculate the distance between points O and B using the distance formula:

Distance = [tex]\sqrt{[(x2 - x1)^2 + (y2 - y1)^2]}[/tex]

        = [tex]\sqrt{[(0 - 0)^2 + (5/4 - 0)^2]}[/tex]

        = [tex]\sqrt{[(5/4)^2]}[/tex]

        =[tex]\sqrt{ [25/16]}[/tex]

        = 5/4

Since OABC is a square, all sides are equal in length. Therefore, the side length of square OABC is 5/4.

To find the surface area of the square, we use the formula:

Surface Area = [tex]Side Length^2[/tex]

            =[tex](5/4)^2[/tex]

            = 25/16

Therefore, the surface area of square OABC is 25/16 square units.

On the 3rd day, the attendance would be 1.1 × 1.1A = 1.21A

On the 4th day, the attendance would be 1.1 × 1.1 × 1.1A = 1.331A

And so on, until the 30th day of June.A = 2000

Therefore, on the 30th day of June, the attendance will be equal to:

Attendance on the 30th day = 2000 × 1.1^29 = 20,062.46 guests (rounded to the nearest whole number)

The attendance in August can be calculated in the same way, except that the rate of change will be negative (i.e., a decrease of 10% per day):

Attendance on the 2nd day = 0.9A

Attendance on the 3rd day = 0.9 × 0.9A = 0.81A

Attendance on the 4th day = 0.9 × 0.9 × 0.9A = 0.729A

And so on, until the 31st day of August.A = 2000

Therefore, on the 31st day of August, the attendance will be equal to: Attendance on the 31st day = 2000 × 0.9^30 = 49.28 guests (rounded to the nearest whole number)

Therefore, the park's attendance on the 30th day of June will be significantly higher than on the 31st day of August.

i) 4 more gallons of petrol will be needed to complete the journey.

ii) The cost of the petrol for the 420 km journey is GH¢55.00.

i) To determine the number of gallons of petrol needed to complete the journey, we can calculate the total distance that can be covered with the available petrol and then subtract it from the total distance of the journey.

Given that the car consumes 1 gallon of petrol for every 30 km, we can calculate the distance that can be covered with 10 gallons of petrol by multiplying 10 (gallons) by 30 (km/gallon):

Distance covered with 10 gallons = 10 * 30 = 300 km

To find the remaining distance that needs to be covered, we subtract the distance covered with the available petrol from the total distance of the journey:

Remaining distance = Total distance - Distance covered with available petrol

Remaining distance = 420 km - 300 km = 120 km

Since the car consumes 1 gallon of petrol for every 30 km, we can determine the additional gallons of petrol needed by dividing the remaining distance by 30:

Additional gallons needed = Remaining distance / 30 = 120 km / 30 km/gallon = 4 gallons

Therefore, the driver will need 4 more gallons of petrol to complete the journey.

ii) To calculate the cost of the petrol for the journey of 420 km, we need to multiply the total number of gallons used for the journey by the cost per gallon.

Given that a gallon of petrol costs GH¢5.50, and the total number of gallons used for the journey is 10 (given in the problem), we can calculate the cost using the formula:

Cost of petrol = Total gallons used * Cost per gallon

Cost of petrol = 10 gallons * GH¢5.50/gallon = GH¢55.00

Therefore, the cost of the petrol for the journey of 420 km is GH¢55.00.
