A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.

PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.

PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.

Answers

Answer:

A. 19.3ft     B. 5.2ft

Step-by-step explanation:

So the ladder leaning against the wall forms a triangle. The hypotenuse of

triangle is the ladder (20) and the angle given between ladder an ground is 75 degrees. Use trig to find the height of the wall which is the leg of the triangle.

Sine of Angle is opposite side/hypotenuse

Cosine of Angle is adjacent side/hypotenuse

so     Sine of 75 degrees  =  Wall height/20

Wall height = 20 times Sine of 75 degrees

Sine of 75 degrees = .9659

20 times (.9659) = 19.3ft

So now use Cosine to find the other leg of the triangle (the distance between the bottom of ladder to the wall)

Cosine of 75 degrees  = Distance wall to base of ladder / 20

Cosine of 75 degrees = .2588

20 times (.2588) = 5.2ft

Find the values of b such that the function has the given maximum value [tex]f(x) = -x^2+bx-65[/tex]. I already have it in vertex form as [tex]-(x+\frac{b}{2})^2-65+\frac{b^2}{4}[/tex] but I don't know what to do from here

Answers

Answer:

b = {20, -20}

Step-by-step explanation:

Given function:

f(x) = -x² + bx - 65 with maximum value of 35

To find

The value of b

Solution:

Maximum value is obtained at vertex as a < 0

Vertex coordinate of x is:

x = -b/2a = -b / -2 = 1/2b

Solving for b:

35 = - (1/2b)² + b(1/2b) - 65- 1/4b² + 1/2b² = 1001/4b² = 100b² = 400b = √400b = ± 20

can someone help me understand how to do this?

Answers

Answer:

1/3

Step-by-step explanation:

To get no solution, you want to get rid of x and leave an incorrect equation.

In this case, we will use 1/3x.

1/3x + 2 = 1/3x - 3

We subtract 1/3x on both sides. This will cause the 1/3x's to cancel out.

1/3x - 1/3x + 2 = 1/3x - 1/3x - 3

2 ≠ -3

As we know, 2 is not 3. Therefore, there is no solution if 1/3x is used.

F = k/d^2

Step-by-step explanation:

We can see from the question that the force of attraction F is proportional to the inverse of the square of the distance separating the bodies, d.

So we have;

F α 1/d^2

So,  introducing a constant of proportionality k,

F = k/d^2

Hence the formula connecting F and d is; F = k/d^2

Causes of World War IBackground InformationWorld War I did not start for one particular reason. People often say that it began with the assassination of Austria-Hungarys Archduke Franz Ferdinand by a Serbian nationalist group, which is true, but is not the only reason. This assassination caused Austria-Hungary to declare war on Serbia, beginning a war that would turn into WWI. This was not the only cause though, in fact, this event was just the catalyst (event that started things) the European countries needed to fight a war which was just waiting to happen.In Europe, the conditions were just right for a world war to begin; they just needed the right push. During the early 1900s European defense agreements were being made across the continent. These agreements said that if one country was attacked or had war declared on them, another country would come and help them. Below is a list of some of the main defense agreements:Serbia and RussiaAustria-Hungary and GermanyRussia and FranceFrance, Belgium, and BritainBritain and JapanAfter Austria-Hungary declared war on Serbia these defense pacts started to go into action. Russia joined, causing Germany to get involved, which brought France into the war, and so on. This turned a war between two countries over an assassination, into a war that involved multiple countries spread over multiple continents. Another cause of WWI had to do with the mentally of the countries in Europe. Many of the countries in Europe had a feeling of nationalism, which is a feeling that your country is the best, along with the desire to prove this to everyone else. When the war began, the defense agreements brought multiple countries into the war, but the feelings of nationalism helped keep everyone fighting and trying to prove they are the strongest. The idea of militarism is another cause of WWI. This is the belief that a country should build and keep a strong military (army, navy, etc.). As a result of militarism, when countries started declaring war on each other, most of these countries already had a strong military just waiting to be used. Not only was the military read to go, the governments and citizens of the country wanted to use it and show their power. A final thought process which led to WWI was that of imperialism. This idea of imperialism, which is a belief a country should extend their power and influence through diplomacy or force, already had countries looking for ways to increase their influence. Prior to WWI starting, countries in Europe were trying to expand their lands in Africa and Asia, due to their imperialist mindsets, which were causing tension in the region. WWI was just the event these countries needed to spread their influence, increase their power, and fulfill their imperialistic ideas.Fill-In-The-BlankUse the information provided about World War I to fill in the blank in each sentence.________________ _____________ Ferdinand was assassinated by a Serbian nationalist group, which essentially started World War I Defense agreements said that if one country was ___________________ or had war declared on them, the other country would come to help. _________________ is a feeling that your country is the best Militarism involves countries building and keeping a strong __________________, which made countries read to fight when WWI started.
