A fishing pole is leaning against a wall. The base of the pole is 0.5 meters away from the wall, forming a 78 degree angle of elevation. How long is the fishing pole? Equation: (Choose One) A. cos0.5 B. cos0.5 C. cos78 = D. cos78 = x 78 78 x x 0.5 0.5 x​

Answers

Answer 1

The length of the fishing pole is approximately 2.40 meters.

the equation is

x = 0.5 / cos (78)

How to find the angle of elevation

The equation that relates the length of the fishing pole, the distance from the base of the pole to the wall, and the angle of elevation is:

cos (angle of elevation) = adjacent / hypotenuse

In this case, the hypotenuse side is the length of the fishing pole, x, and the adjacent side is the distance from the base of the pole to the wall, 0.5 meters. The angle of elevation is 78 degrees. Therefore:

cos (78) = 0.5 / x

x = 0.5 / cos (78)

x ≈ 2.40 meters

Therefore, the length of the fishing pole is approximately 2.40 meters.

the mean and the median of the given data set are 16.75 and 9.5 respectively.

What is Mean?

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Given,  A data set 8, 9, 10, 40

From the general formula of mean:

mean =  (sum of observations) ÷ (total number of observations).

mean = (8 + 9 + 10+ 40)/4

mean = 67/4

mean = 16.75

Since the median is:

The median is the value that's exactly in the middle of a dataset when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values.

Thus,

the median of the given data set = (9 +10)/2

the median of the given data set =  9.5

Therefore, the mean and the median of the given data set are 16.75 and 9.5 respectively.

solve for v. 4v-18=6(v-6)

Answers

Answer:

v = 9

Step-by-step explanation:

4v - 18 = 6(v - 6)

1.) Distribute 6 into the parenthesis

4v-18 = 6v - 36

2.) Move 6v to the other side by subtracting from both sides

4v - 6v -18 = -36

3.) Move 18 to the other side by adding 18 on both sides

4v - 6v = 18 + -36

4.) Combine like terms

-2v = -18

5.) Divide -2 on both sides to get v by itself

v = 9

Answer:

the answer is 9

Step-by-step explanation:

4v-18=6(v-6)

4v-18=6v-36

4v-6v= -36+18

-2v= -18

divide both sides by -2

ting is making a circular garden with a radius of 6 feet.How far across is the garden at its widest point?What is the length of edging material to the nearest hundredth needed to enclose the garden?Use 3.14

Answers

The length of edging material needed to enclose the garden is approximately 37.68 feet to the nearest hundredth.

Describe Circumference of circle?

The circumference of a circle is the distance around its outer boundary, also known as its perimeter. It is one of the fundamental properties of a circle, along with its radius and diameter.

Since the garden is circular, its widest point is its diameter, which is twice the radius. Therefore, the widest point of the garden is 12 feet across.

To find the length of the edging material needed to enclose the garden, we need to find the circumference of the circle. The formula for the circumference of a circle is C = 2πr, where r is the radius and π (pi) is approximately 3.14. Substituting,  r = 6 into the formula, we get:

C = 2π(6)

C = 12π

To approximate this value using 3.14, we can substitute π = 3.14 and get:

C ≈ 12(3.14)

C ≈ 37.68

Therefore, the length of edging material needed to enclose the garden is approximately 37.68 feet to the nearest hundredth.

Answers

Answer:

To solve this problem, we need to calculate the cost of each travel and instruction option and then determine which options Treena can afford with her $1000 scholarship.

Option 1: Air travel and individual instruction

Travel cost: $335

Instruction cost: 7 x $60 = $420

Total cost: $335 + $420 = $755

Option 2: Air travel and group instruction

Travel cost: $335

Instruction cost: 7 x $40 = $280

Total cost: $335 + $280 = $615

Option 3: Train travel and individual instruction

Travel cost: $125

Instruction cost: 7 x $60 = $420

Total cost: $125 + $420 = $545

Option 4: Train travel and group instruction

Travel cost: $125

Instruction cost: 7 x $40 = $280

Total cost: $125 + $280 = $405

Now we need to determine which options Treena can afford with her $1000 scholarship. We'll start with the most expensive option and work our way down.

Option 1: $755

This option is too expensive for Treena's $1000 scholarship.

Option 2: $615

This option is also too expensive for Treena's $1000 scholarship.

Option 3: $545

This option is within Treena's budget, but she won't have any money left for food.

Option 4: $405

This option is also within Treena's budget, and she'll have $595 left for food.

Therefore, Treena's choices of travel and instruction plans that she could afford to make are:

- Train travel and group instruction with $595 left for food

- Train travel and individual instruction with no money left for food

how to find the missing dimension of. a cone when the when the highest s 4.2 and the volume is 3.6 cubed

Answers

To find the missing dimension of a cone when the height is 4.2 and the volume is 3.6 cubed is to equate the general formula with the given information.

What is a cone?

A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreasing to a certain point.

The volume of a cone is (1/3)πr²h.

The total surface area of a cone is πr(r + l).

The curved surface area is πrl.

To obtain the missing dimension of a cone we must equate the general formula for the volume of a cone to the given information.

Therefore, (1/3)πr²×4.2 = 3.6

(1/3)πr² = 0.86.

r² = 0.86/1.05.

r² = 0.82.

r = 0.9

In ΔNOP, p = 490 inches, m∠N=57° and m∠O=55°. Find the length of n, to the nearest inch.

Answers

The value of n is 443 inches when using the triangle rule and law of sine.

What is meant by Sine Rule?An oblique triangle's sides and angles are related according to the rule of sines (non-right triangle). The laws of sines and cosines are crucial trigonometrical formulas for "solving a triangle." The sine rule states that there is an equal relationship between a triangle's side lengths and the sine of each of its opposite angles.Triangles' side length to opposite angle ratios are governed by the law of sines. For all three sides and perpendicular angles, this ratio remains constant. So long as the necessary information is known, we may use the sine rule to determine the missing side or angle of any triangle.

The formula is given as

a / sin A = b / sin B = c / sin C

In this triangle NOP, we can find the value of angle P

∠N + ∠O + ∠P = 180

57 + 55 + ∠P = 180  : Sum of angles in a triangle is equal 180 degrees

∠P = 180 - 112

∠P = 68

Using law of sine

p/sin P = n/sin N

490/sin68 = n / sin57

n = [(490 × sin 57) / sin 68]

n = 443 inches

In the problem, the proportion of the sides are equal and this will maintain the size of the angle

let the size of the angle be x

How do you visualizationa Kruskal algorithm?

Answers

Visualizing Kruskal's algorithm involves representing the graph, its edges, and the minimum spanning tree in a visual format.

To visualize a Kruskal algorithm, you need to follow the steps below:

1. Sort all the edges in ascending order of weight.
2. Create a new graph G' with the same vertices as the original graph G, but no edges.
3. Start with the smallest edge and add it to G' if it doesn't create a cycle. Repeat this step until you have added all the edges or you have a minimum spanning tree.
4. If you have a minimum spanning tree, you can visualize it by drawing the graph with the edges included in G'.

Here is an example:

Original graph G:

A---2---B---3---C
|       |
4       1
|       |
D---5---E

Step 1: Sort the edges in ascending order of weight: 1, 2, 3, 4, 5

Step 2: Create a new graph G' with the same vertices as G, but no edges.

Step 3: Start with the smallest edge (1) and add it to G'. This doesn't create a cycle, so we can add it.

G':
A       B---1---C
|       |
4       1
|       |
D       E

Next, add the second smallest edge (2) to G'. This also doesn't create a cycle, so we can add it.

G':
A---2---B---1---C
|       |
4       1
|       |
D       E

Continue this process until you have added all the edges or you have a minimum spanning tree.

Step 4: Visualize the minimum spanning tree by drawing the graph with the edges included in G'.
