Answer:

[tex]\tan{90^{\circ}}[/tex]

Step-by-step explanation:

Because [tex]\cos{x}[/tex] and [tex]\sin{x}[/tex] are defined for all [tex]x[/tex](i.e. their domain is [tex](-\infty, \infty)[/tex]), so they can never be undefined. However, [tex]\tan{90}=\sin{90}/\cos{90}=\sin{90}/0[/tex], which is undefined, because you can't divide by [tex]0[/tex]. So, the answer is [tex]\boxed{\tan{90^{\circ}}}[/tex]

Answer:

-5, -9

Answer:o

Step-by-step explanation:o

Answer:

1) INF

2) NS

Because:

1 is INF because both sides of the equation are the same

x can be replaced with any number therefor, there are infinite solutions.

2 is NS because you are left with 12=2 so there would not be a solution.

Answer:

Step-by-step explanation:

[tex]1) Sin \ C = \dfrac{opposite side of C}{Hypotenuse}=\dfrac{21}{29}\\\\2)Sin \ C = \dfrac{30}{50}=\dfrac{3}{5}\\\\3) Cos \ C = \dfrac{adjacent \ side \ of \ C}{hypotenuse}=\dfrac{36}{39}=\dfrac{12}{13}\\\\4) Cos \ C =\dfrac{8}{17}[/tex]

We can make x the subject of the equation by moving all the other terms to the opposite side of the equal sign while x is on the next.

  x/y+z=w                       [multiply both sides by y+z]

        x = w (y + z)

Answer:

The answer is 3!!

Step-by-step explanation:

Step 1)

6x-2=x+13

6x − 2 + 2 = x + 13 +2

Step2)

6 = + 15

Step3)

6 − =+15−

Step 4)

5=15

Step5)

5x=15

Divide both sides

5x/5 = 15/5

Step 6)

X = 3!!

Answer:

distributive property of multiplication.

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

a + 54° = 180° [Angles on a straight line]

a = 180 - 54

a = 126°

a + b = 180 [Angles on a straight line add up to 180 degrees]

126 + b = 180

b = 180 - 126

b = 54°

c° = a° [Vertically opposite angles are equal]

c° = 126°

d = 54° [Corresponding angles are equal]

e = a [Corresponding angles are equal]

e = 126°

f = b [Corresponding angles are equal]

f = 54°

g = c [Corresponding angles]

g = 126°

Hello! Your answer should be: the summary lacks transitions that connect ideas.

Step-by-step explanation:

Sorry if it is wrong :(

The summary needs to be revised because The summary lacks transitions that connect ideas.

A summary is a brief statement or account of the main points of something. The summary is essentially a short version of a longer text. The size of a summary can vary based on the type of writing, but most often it is no longer than a page.

They are used to give an overview of what happens in the writing and review the main themes. This lesson will continue to explore what summary writing is, types of summaries, and examples of summaries.

Keeping the summary concise will give the reader the information they need the most, without any unnecessary information.

A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively. The most dangerous type of eruption is called a 'glowing avalanche' which occurs when freshly erupted magma flows down the sides of a volcano.

Volcanic eruption can come from side branches or from the top of the volcano. Some volcanic eruption  are terrible explosions that throw out huge amounts of rock and volcanic ash and can be disastrous for the people and animals that are living nearby to it .

Volcanic eruption are often named after famous volcanoes where that type of eruption has been seen. Some volcanoes may show only one type of eruption during a period of activity, while others may show a range of types in a series.

Hence, option C is the correct answer

For this sort of problem, you need to be familiar with prefixes.

So:

megabyte = [tex]1 *10^6[/tex] bytes

kilobyte = [tex]1*10^3[/tex] bytes

and a regular byte would just be [tex]1[/tex]

Now, you will need to do a conversion:

[tex]1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}[/tex]

I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are [tex]1*10^6[/tex] bytes!)

In the second fraction thought, remember one kilobyte is [tex]1*10^3[/tex] bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do [tex]\frac{1kilobyte}{1*10^3bytes}[/tex], but I think it is more correct to do write it out how I did).

*** They do equal the same thing though! Do whichever way is easier for you!

Now, your answer should be:

[tex]10^3[/tex] kilobytes (1000 kilobytes)

Answer:

14x - y = 62

Step-by-step explanation:

Hi there!

We are given the equation y=14x-62 and we want to put it into standard form.

Standard form is ax + by = c, where a, b, and c are free integer coefficients, but a and b cannot be equal to zero, and a cannot be negative

The equation is currently in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

Since standard form has the term with x in it on the left side, we can move 14x to the left side (subtract 14x from both sides)

y = 14x-62

-14x -14x

_________________

-14x + y = -62

Remember that a (coefficient of x) cannot be negative. So multiply everything by -1 to change the sign of all the terms

-1(-14x + y) = -1(-62)

14x - y = 62

Answer: False

Step-by-step explanation:

A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means

Add -2 (loses ⇒ means getting less)

Then the cup loses 2 ounces of water in the second minute. This mathematically means

Add -2 (loses ⇒ means getting less)

In total,  and means loses 4 ounces in two minutes.

Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false

Step-by-step explanation:

Answer:

The correct choice is option B. y + 5 = 2(x−4)

Step-by-step explanation:

slope = 2

y = mx + b

-5 = 2(4) + b

-5 = 8 + b

-8    -8

------------------

-13 = b

y = 2x - 13, in other words --> y + 5 = 2(x−4)

So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).

  6x -7 units

Step-by-step explanation:

Let c represent the length of the third side. The perimeter is the sum of the three side lengths.

  P = a + b + c

  (17x -5) = (3x +5) +(8x -3) +c

 17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms
