Answer 1

Answer:

[tex]x = 3.7[/tex]

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

[tex] {5}^{2} + {5}^{2} = {x}^{2} [/tex]

[tex]25 + 25 = {x}^{2} [/tex]

[tex]50 = {x}^{2} [/tex]

[tex]x = 5 \sqrt{2} [/tex]

Now we can apply pythagorean theorem on the other triangle

[tex](5 \sqrt{2} ) {}^{2} + {x}^{2} = {8}^{2} [/tex]

[tex]50 + {x}^{2} = 64[/tex]

[tex] {x}^{2} = 14[/tex]

[tex]x = \sqrt{14} [/tex]

[tex]x = 3.7[/tex]

Answer 2

Answer:

Step-by-step explanation:

use Pythagoras's theorem to find the hypontenuse of the isosceles triangle on the right side.

hyp = sqrt [ 5^2 + 5^2 ]

hyp = sqrt [ 50 ]

hyp = 7.0710678

now we know the adjacent side of the triangle on the left , since it's the same as the hypotenuse of the triangle on the right.

SOH CAH TOA ( to remember how the trig funct. fit on triangles)

CAH Cos(Ф) = adj / hyp

cos(Ф) = 7.0710678 / 8

Ф = arcCos( 7.0710678 / 8 )

Ф = 27.8855668°

TOA Tan(Ф) = x / 7.0710678

Tan( 27.8855668° ) = x / 7.0710678

7.0710678 * Tan( 27.8855668° ) = x

3.741657 = x

x = 3.7 ( to the nearest 10th )

Answers

Answer:

a=12

Step-by-step explanation:

We must use SOH, CAH, TOA

SOH= Sin0=opp/hyp

CAH=Cos0=adj/hyp

TOA= Tan0=opp/adj

Since we have opposite and hypotenuse we use Sin ratio, in this case,

sin30°= [tex]\frac{a}{24}[/tex]

[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply

[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself

a=12

Answer:

a = 12

Step-by-step explanation:

To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;

Sin(30) = [tex]\frac{a}{24}[/tex]

Sin(30) * 24 = a

12 = a

What is the value of x?

Answers

Answer:

x = 80 degrees

Step-by-step explanation:

First look at the upper triangle. There are two 65 degree angles there, along with two equal sides. The angles must sum up to 180 degrees. Therefore:

2(65) + x = 180; thus, the value of x is 50 degrees.

Next, recognize that the vertical angles in the middle of the diagram are equal and are 50 degrees each. Thus, the smaller triangle has two 50-degree angles. Again we sum up the angles, obtaining 50 + 50 + x = 180, or x = 80 degrees

So now we take off that 7 from the 13:

13 - 7 = 6

So now we find the area of that little area:

6 x 5 = 30

Now we do the other rectangle:

12 x 7 = 84

Now we add them together:

84 + 30 = 114

So the area of the shape is 114cm²

[tex] \sqrt{60i - 11} [/tex]

Answers

The equivalent of the complex number expression is [tex]\sqrt{60i - 11}[/tex] is 2 + 15i

How to rewrite the expression?

The complex number expression is given as:

[tex]\sqrt{60i - 11}[/tex]

Rewrite as:

[tex]a + bi = \sqrt{60i - 11}[/tex]

Take the square of both sides

[tex]a^2 + 2abi - b = 60i - 11[/tex]

By comparison, we have:

a^2 - b = -11

2ab = 60

Divide both sides by 2

ab = 30

Using a graphical tool, we have:

a = 2,b = 15

So, we have:

a + bi = 2 + 15i

Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.

Isolate h to find the maximum number of hours she can rent the boat:

2h + 8 ≤ 32

First, subtract 8 from both sides.

2h ≤ 16

Then divide both sides by 2.

h ≤ 8

h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.

Step-by-step explanation:

x^2 - 5x + 3 = -3

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0

x - 3 = 0 or x - 2 = 0

x = 3 or x = 2

We are given y = -3.

Step-by-step explanation:

One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,

[tex]f(x)=x^2-5x+3[/tex]

Set this equation up, and solve to find the value of (x) that satisfies this requirement:

[tex]f(x)=x^2-5x+3=-3[/tex]

Inverse operations,

[tex]x^2-5x+6=0[/tex]

Factor, rewrite the quadratic equation as the product of two linear equations,

(February 24, 1959)Fellow peasants:Many symbols expressed the extraordinary transformations that are taking place in our country, symbols that are as lights showing the way to our people.We have celebrated many times the anniversary of the 24 of February. But this is the first which really represents the end of our fight for independence. It was initiated by our grand-parents against Spain, and we have finally obtained it on the first of January, 1959.We are tonight in the Cuartel Moncada, the place where the fight against Tyranny was initiated. Tonight, it is the symbol of our Revolution Many have not noticed yet the many changes that have taken place in Cuba. I can read everywhere signs speaking about Agrarian Reform, about the Destruction of "latifundia" about technical assistance, about comfortable houses for the peasants. These are the deepest yearnings of a class that has always been a victim.But I ask myself, what have the peasants to ask from the government? They must not ask anything from us, the time for asking is over I was not born poor, I was born rich. I was not the son of a landless peasant, I was the son of a rich landowner. I never lived in a miserable house. I was near poorness but I never suffered from it. That is why I do not defend landowners but the people and the peasants Together we have lived through many dreams. We are so united in brotherhood, nothing can separate us. Of those peasants we had found when we landed we made rebel soldiers. That is why we can say that the Rebel Army is fundamentally a peasant army. We owe our victory to the peasants.The Prime Minister is a leader of the peasants and nobody can defend them better than he. That is why I am here tonight.Nothing makes me so enthusiastic as the Agrarian Reform. We are not men of promises, but men of facts. So, you can be sure that this deep yearning of the peasants shall be accomplished. We shall give the land to the peasants These things must be well known. The war was won by doing the things that had to be done. One mistake and we would have lost. That is why after the military victory, we must accomplish the revolutionary victory and we have to do the things that have to be done. One - mistake and the Revolution would be lost. I have come to tell the peasants how they can win this war and to ask them if they have confidence in us. We need one single direction and each man must be a disciplined soldier First came the Agrarian Law of the Rebel Army. We made it because we knew we would find many difficulties after the victory, and we promulgated laws in the territories we had liberated, to have that on our side.That was why we gave 70 acres to each peasant, and gave them facilities to buy them. It was so established in the Constitution and we were following the Constitution.These peasants were given the land and they shall keep it, nobody shall take them away from there. We have now to take care if the procedure, the Rebel Army did not have time to give legal form to this act. But this is easy to do, and the peasants shall stay in the land they own now.But now we have another problem: the peasants who have not been given any land. The Agrarian Reform shall take care of this All those who work on a piece of land must stay there. It shall be given to them. But thousands of families do not have any land at all. To cope with this situation we need time. If it could be done in three minutes it should be done so. But the Agrarian Reform takes time and a lot of studying.We have developed a national campaign to make everybody work for the Agrarian Reform. Even the industrials. I told them that the Agrarian Reform would increase the national income and that their - industries would also be increased. If a man has no money, how can he buy shoes? If we open a shoe factory we would have to close it in three weeks. The Agrarian Reform is the only way to fight unemployment.When people are hungry, you just cannot tell them to keep quiet. It is necessary first to eliminate hunger in the land, it will then be finished in the cities. The peasants will be able to buy what the new industries manufacture.Without the Agrarian Reform, the country's economy will crack down and Batista and his men would be back. Without Agrarian Reform everybody would be ruined. That is why it is so important to eliminate the "latifundia."We must be careful not to ruin what we have accomplished. We must be calm.
