Answer:

Step-by-step explanation:

You want the measures of supplementary angles x° and (x-58)°.

Consecutive interior angles where a transversal crosses parallel lines are supplementary.

  x° +(x -58)° = 180°

  2x = 238

  x = 119

  x -58 = 61

The two angles are ...

The pounds of trash that Janicka recycle is 3 3/5 pounds.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split.

In this situation, Janicka picked up 5 2/5 lb of trash and 2/3 of what she collected was able to be recycled.

The amount to be recycled will be:

= 2/3 × 5 2/5

= 2/3 × 27/5

= 54 / 15

= 3 9/15

= 3 3/5

Cassidy and Calvin have the same amount of money in 11 months.

The amount is $370.

Cassidy has $425 in her savings account, and she has to pay $5 each month to her parents for her cell phone. This will be:

= 425 - 5m

Calvin has $95 and he saves $25 each month from his job walking dogs for his neighbor. This will be:

= 95 + 25m

where m = number of months

The equation will be:

425 - 5m = 95 + 25m

Collect like terms

425 - 95 = 25m + 5m

330 = 30m

Divide

m= 330/30

m = 11

The number of months is 11.

The amount will be:

= 425 - 5m

= 425 - 5(11)

= 425 - 55.

= 370

Number multiplication is a basic and common operation. However, the product of multiplication can be stated differently at times, whether to reduce the equation or to explain the mathematics required. Many numbers can be expressed exponentially.

The concept of exponential form is a method of expressing a number that has been multiplied by itself several times. The fundamental formula is [tex]\mathbf{y=b^x}[/tex]

Exponential expressions are simply a shorthand way of writing powers. The exponent specifies how many times the base has been utilized as a factor.

Answer:

The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!

Step-by-step explanation:

In 1927, an astronomer named Georges Lemaître had a big idea. He said that a very long time ago, the universe started as just a single point. He said the universe stretched and expanded to get as big as it is now, and that it could keep on stretching The universe is a very big place, and it’s been around for a very long time. Thinking about how it all started is hard to imagine. Some More Information

Just two years later, an astronomer named Edwin Hubble noticed that other galaxies were moving away from us. And that’s not all. The farthest galaxies were moving faster than the ones close to us. This meant that the universe was still expanding, just like Lemaître thought. If things were moving apart, it meant that long ago, everything had been close together.

Everything we can see in our universe today—stars, planets, comets, asteroids—they weren't there at the beginning. Where did they come from?

A Tiny, Hot Beginning

When the universe began, it was just hot, tiny particles mixed with light and energy. It was nothing like what we see now. As everything expanded and took up more space, it cooled down.

The tiny particles grouped together. They formed atoms. Then those atoms grouped together. Over lots of time, atoms came together to form stars and galaxies.

The first stars created bigger atoms and groups of atoms. That led to more stars being born. At the same time, galaxies were crashing and grouping together. As new stars were being born and dying, then things like asteroids, comets, planets, and black holes formed!

When red is the first one , blue the second and green the third one (and as you can see, all of them share the vertex (-2, 3)).

The vertex of a quadratic equation:

a[tex]x^{2}[/tex]+bx + c = y

is located at :

x = -b/2a.

In this case, x = -2

Then,

-b/2a = -2

And we also have that:

a[tex](-2)^2[/tex] -2b + c = 3

Then we have two equations:

-b/2a = -2

a[tex](-2)^2[/tex] -2b + c = 3

We have only equations and 3 variables, So we can just give the variable c different values and we will find different quadratic equations that are not equivalent.

Let's begin with c = 0 ,Our equations are:

-b/2a = -2

a[tex](-2)^2[/tex] -2b + 0 = 3

In the first equation we can isolate b and get :

b = 4a

Now we can replace this in the other equation and solve this for a.

4a + 4a x -2 = 3

-4a = 3

a = -3/4

then:

b = 4a = 4 x -3/4 = -3

The first quadratic equation is:

(-3/4)[tex]x^{2}[/tex] - 3x = y

Now, To find the second let's use a different value of c.

c = 1

b = 4a

a[tex](-2)^2[/tex] -2b + 1 = 3

Let's solve in the same way as before:

4a + 4a x -2 + 1= 3

-4a = 2

a = 2/-4 = 1/-2

b = 4 x -1/2 = -2

Then our equation is :

(-1/2)[tex]x^{2}[/tex] -2x + 1 = y

For the last equation, let's use c = 2

then our equation are:

b = 4a

a(-2)^2 - 2b +2 = 3

Same as before, replace the first equation in the second

4a + 4a x-2 +2 = 3

-4a +2 = 3

-4a = 1

a = -1/4

Then:

b = 4 x (-1/4) = -1

Our third equation is :

(-1/4)x^2 - x + 2 = y

Now, Below you can see all of them graphed.

The statement that is true about the number of rooms that can be painted using inequality is; D.

The hotel can repaint 2 rooms, but this number is neither the maximum nor the minimum.

We are given;

Budget of hotel to repaint the lobby and some hotel rooms; $63750

Amount spent on painting the lobby = $26700

Cost to paint each room = $4250

Thus, the inequality to represent the given situation is;

26,700 + 4,250n ≤ $63,750

where;

n is number of rooms the hotel can repaint

Subtract 26700 from both sides of the inequality to get;

4250n ≤ 37050

n ≤ 37050/4250

n ≤ 8.717

Since we can't paint only a portion, we leave it as a maximum of 8 rooms

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

What is domain?

The domain of a function is the set of values that we are allowed to plug into our function.

What is range?

The collection of potential output values for a function is known as its range. For instance, the range is the non-negative real numbers for the function fn(x)=x2 on the domain of all real numbers (x ∈ R), which may be represented as fn(x)≥0 (or [0,∞] using interval notation).

Given:

Domain: {-5, -3, 0, 3, 11)

Range: {4, 0, 2}

If the input of function is a and output is b then it is defined by (a, b).

a always belong to domain and b from range of function.

The exact value of the sine of angle 78° sin(78°) is presented as follows;

[tex]sin(78^{\circ}) = \dfrac{\sqrt{5}-1+\sqrt{\sqrt{5}\cdot \left(6+6\cdot \sqrt{5} \right) } }{8}[/tex]

The sine of an angle is found by taking the ratio of the opposite side to the hypotenuse side of a right triangle that has the specified angle.

The sine of angle 78° is found from the sine of the sum of two angles (60° + 18°)  as follows;

sin(78°) = sin(60° + 18°)

sin(A + B) = sin(A)·cos(B) + cos(A)·sin(B)

Therefore, sin(78°) = sin(60° + 18°)  = sin(60)·cos(18°) + cos(60°)·sin(18°)

Where, 18° = A, we have;

5·A = 90°

2·A = 90° - 3·A

sin(2·A) = sin(90° - 3·A) = cos(3·A)

2·sin(A)·cos(A) = 4·cos³(A) - 3·cos(A)

2·sin(A)·cos(A) - (4·cos³(A) - 3·cos(A)) = 0

2·sin(A) - (4·cos²(A) - 3) = 0

2·sin(A) - (4·(1 - sin²(A)) - 3) = 0

4·sin²(A) - 2·sin(A) - 1 = 0

Which gives;

[tex]sin(A) = \dfrac{-1\pm \sqrt{5} }{4}[/tex]

cos²(18°) = 1 - sin²(18°)

cos(18°) = √(1 - sin²(18°))

[tex]cos(18^{\circ}) =\sqrt{1 - \left( \dfrac{\sqrt{5} -1 }{4}\right)^2} = \dfrac{1}{4} \cdot \sqrt{10+2\cdot \sqrt{5} }[/tex]

[tex]cos(18^{\circ}) = \dfrac{1}{4} \cdot \sqrt{10+2\cdot \sqrt{5} }[/tex]
