Answer:

[tex]cos\theta = -\frac{12}{37}[/tex]

Step-by-step explanation:

Given

[tex]tan\theta = \frac{35}{12}[/tex]

Quadrant: 3rd

Required

Determine [tex]cos\theta[/tex]

This question will be solved using the Pythagoras theorem

[tex]Hyp^2 = Adj^2 + Opp^2[/tex]

The tangent of an angle is calculated as thus;

[tex]tan\theta = \frac{Opp}{Adj}[/tex]

Comparing

[tex]tan\theta = \frac{35}{12}[/tex] to [tex]tan\theta = \frac{Opp}{Adj}[/tex]

We can conclude that

[tex]Opp = 35[/tex]    [tex]Adj = 12[/tex]

Substitute these values in the Pythagoras formula

[tex]Hyp^2 = 35^2 + 12^2[/tex]

[tex]Hyp^2 = 1225 + 144[/tex]

[tex]Hyp^2 = 1369[/tex]

Square root of both sides

[tex]Hyp = \sqrt{1369}[/tex]

[tex]Hyp = 37[/tex]

SInce [tex]\theta[/tex] is in the 3rd quadrant, then

[tex]cos\theta = -\frac{Adj}{Hyp}[/tex]

Where [tex]Adj = 12[/tex] and [tex]Hyp = 37[/tex]

[tex]cos\theta = -\frac{12}{37}[/tex]

Answer:

7560.

Step-by-step explanation:

There are 9 letters after the M consisting of  3 O's, 2 H's, 2 H's and 2 E's.

So the number of ways is   9! / (3!*2!*2!*2!)

= 362880 / (6*2*2*2)

= 362880 / 48

= 7560.

The number of ways the word MOSHOESHOE can be rearranged, if the letter M must always begin a word is 75,600 ways

Given:

MOSHOESHOE

n = total number of letters = 10

a = number of times O appears = 3

b = number of times S appears = 2

c = number of times E appears = 2

d = number of times H appears = 2

number of ways the word can be rearranged if M must always begin a word

= n! / (a! b! c! d!)

= 10! / (3!, 2!, 2!, 2!)

= (10 × 9 × 8 × 7 × 6 × 5 × 4× 3 × 2 × 1) / (3 × 2 × 1, 2 × 1, 2 × 1, 2 × 1)

= 3,628,800 / (6 × 2 × 2 × 2)

= 3,628,800 / 48

= 75,600 ways

Therefore, the number of ways the word can be rearranged if M must always begin a word is 75,600 ways

Answer:

Jeremy has 12 ways of painting his room.

He has 4 different wall colors and 3 different trim colors, so, if we want to know how many ways does he have to paint his room, we only need to multiply:

4 * 3 = 12

That's why he has 12 ways of painting his room. That's because for each of the 4 different wall colors, there are 3 trim colors he can use.

Answer: 12 different ways

Step-by-step explanation:

The question is asking for a combination of a wall color and a trim color because his room required one wall color and one trim color.

In this case, combination will be the number of first kind multiplies with the second kind. This is similar to sketching a tree diagram but instead, we will be using numerical method which will be quicker.

If you are still confused, I will provide some examples.

This also applies to your question. You have 4 different wall colors and 3 different trim colors.

4×3=12

You have 12 different ways to paint the room

The common ratio of the geometric sequence is -1/3

What is Geometric Progression?

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric sequence be represented by A

Now , the value of A is

A = 18 , -6 , 2 , -2/3

Let the first term of the geometric sequence be = a₁

The value of a₁ = 18

Let the second term of the geometric sequence be = a₂

The value of a₂ = -6

And , the common ratio r is given by the formula

Common ratio r = second term / first term

Substituting the values in the equation , we get

Common ratio r = -6/18

On simplifying the equation , we get

Common ratio r = -1/3

Therefore , the ratio is -1/3

Hence , The common ratio of the geometric sequence is -1/3

Ok, el elevador comienza en el piso 0, y llega hasta el piso 9 después de 5 movimientos.

De estos 5 movimientos, 3 suben (los podemos definir como positivos)

y 2 bajan (los escribimos como negativos).

Entonces, comienzo en 0.

0 + A + B + C - D - E = 9.

ahí dice que:

"desde el piso 0, tengo 3 subidas y dos bajadas de tal forma que el resultado final es el piso 9"

{-5, -4, 0, 1, 2}

Step-by-step explanation:

The domain is the inputs or the x values

{-5, -4, 0, 1, 2}

Answer:

See below.

Step-by-step explanation:

The domain of a relation is all of the x-coordinates.

So we have the relation:

{(-5,4), (-4,2), (0,2), (1,3), (2,4)}

This means that the domain will be the following values:

{(-5,4), (-4,2), (0,2), (1,3), (2,4)}

So, our domain is:

[tex]\{-5, -4, 0, 1, 2\}[/tex]

Answer:

-45

Step-by-step explanation:

The question is asking for the sum of the sequence. Therefore, there is no such thing as a "radians" answer.

When you evaluate the sum, you should get -45 as your answer. To find so, you simply plug in 1 as n and other numbers then add the result.

The sum telescopes. Consider the N-th partial sum of the series,

[tex]S_N=\displaystyle\sum_{n=1}^N\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)[/tex]

[tex]S_N=\bigg(\tan^{-1}\sqrt1-\tan^{-1}\sqrt2\bigg)+\bigg(\tan^{-1}\sqrt2-\tan^{-1}\sqrt3\bigg)+\bigg(\tan^{-1}\sqrt3-\tan^{-1}\sqrt4\bigg)+\cdots+\bigg(\tan^{-1}\sqrt N-\tan^{-1}\sqrt{N+1}\bigg)[/tex]

Notice how [tex]\tan^{-1}\sqrt2[/tex] is added, then immediately subtracted. The same goes for [tex]\tan^{-1}\sqrt3[/tex], then [tex]\tan^{-1}\sqrt4[/tex], and so on, up to [tex]\tan^{-1}\sqrt N[/tex]. This leaves us with

[tex]S_N=\tan^{-1}\sqrt1-\tan^{-1}\sqrt{N+1}[/tex]

The value of the given sum is obtained as [tex]N\to\infty[/tex]. We get

[tex]\displaystyle\sum_{n=1}^\infty\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)=\lim_{N\to\infty}S_N=\tan^{-1}1-\lim_{N\to\infty}\tan^{-1}\sqrt{N+1}[/tex]

To compute the limit, recall that [tex]\tan^{-1}x[/tex] has a range of [tex]\left(-\frac\pi2,\frac\pi2\right)[/tex]; in particular, [tex]\tan^{-1}x\to\frac\pi2[/tex] as [tex]x\to\infty[/tex]. So we have

[tex]\displaystyle\sum_{n=1}^\infty\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)=\frac\pi4-\frac\pi2=\boxed{-\frac\pi4}[/tex]

Answer:

The correct answer is rational.

Step-by-step explanation:

The diameter of the tree belongs to the subset of rational numbers.

Natural numbers are the numbers 1, 2, 3 4, etc. Since 18.5 has a fractional/decimal component, it is not considered a natural number.  Whole numbers include all of the natural numbers, as well as 0; therefore, 18.5 is not a whole number either.

Integers include all whole numbers as well as negative numbers, but the integer category still does not encompass numbers with a decimal component.  For this reason, 18.5 is not an integer either.

Therefore, the only subset of numbers that 18.5 can fall under is rational numbers.  A rational number is a number that can be represented as a fraction.  18.5 can be represented as 37/2 and is thus a rational number.

You can also refer to the infographic given in the question for further clarity on which subsets of numbers are more inclusive than others.

Step-by-step explanation:

I guess you mean 1cm:100000cm

Hence, for every 1 cm on the map 100000 cm is covered on the land.

Take the distance on the map for 20 km be x

Hence, 1:100000:: x: 2000000 cm

In order to solve this ratio, you must multiply the extremes and the moderates (nears).

Hence, 2000000×1=100000×x [1km=100000 cm]

Hence, 2000000= 100000x

Hence, x=2000000/100000 cm

Hence, x=20 cm

Hence, 20 cm on the map
