Yes they do because the sun evaporates the water and then it circles around and ends up in the sky

If you write all the whole numbers from 1 to 500 in a row, what will be the 500th digit?

Hitman42 [59]

Answer:

Option A.

Step-by-step explanation:

We need to find the 500th digit if we write all the whole numbers from 1 to 500 in a row.

Single digit numbers are : 1-9 = 9 number = 9 digits

Double digit numbers are : 10-99 = 90 number = 180 digits

Total digits form 1 to 99 = 9+180 = 189

Now,

$500-189=311$

It means we have write 311 more digits.

After 99 we have 3 digit number.

311 is not divisible by 3. The number immediate before 311 which is divisible by 3 is 309.

$\frac{309}{2}=103$

It means the required digit is 2nd digit of 104th number after 99.

104th number after 99 is 203 and second digit of 203 is 0.

Therefore, the correct option is A.

What is 3/-4 ÷ (-2 1/3)

attashe74 [19]

Answer:

9/28

Step-by-step explanation:

First transform -2 1/3 to -7/3. Then find the reciprocal of -7/3 which is -3/7. Multiply that to 3/-4 which becomes -9/-28 which equals 9/28.

I'm super confused on parts g and h because no formula is given, just the limit values. These are the values:

Mrrafil [7]

Answer:

See below.

Step-by-step explanation:

1)

So we have the limit:

$\lim_{x\to 4} (f\circ g)(x)$

This is equivalent to:

$\lim_{x\to 4} f(g(x))$

To solve, we can use the following property:

$\lim_{x \to c} f(g(x))=f( \lim_{x \to c} g(x))$

Therefore, our limit is the same as:

$\lim_{x\to 4} f(g(x))\\=f(\lim_{x\to 4} g(x))$

We are already given that the limit as x approaches 4 of g(x) is -2. Therefore:

$=f(-2)$

You simply need to evaluate this to solve the limit. I don't have enough information to solve this, so maybe you have something more.

Similarly, for the second one:

2)

We have:

$\lim_{x\to 4} (g\circ f)(x)\\=\lim_{x\to 4}g(f(x))$

Using the same property:

$=g(\lim_{x\to 4} f(x))$

And we are told that this is 16, so:

$=g(16)$

And we just need to evaluate this to find the limit.

I hope you find this helpful!

I need help!! please, you don’t even have to do it all just explain to me how to do the first one I’ll catch on

Hi there!

<u>What we need to know:</u>

The three main trigonometric ratios are sine, cosine and tangent:

$\displaystyle sin\theta=\frac{opposite}{hypotenuse}$ $\displaystyle cos\theta=\frac{adjacent}{hypotenuse}$ $\displaystyle tan\theta=\frac{opposite}{adjacent}$

"Opposite" refers to the side opposite the angle that is not the hypotenuse.

"Hypotenuse" refers to the side opposite the right angle of a right triangle.

"Adjacent" refers to the side next to the angle that is not the hypotenuse.

"θ" is read as "theta". It just represents the angle.

Keep in mind that these three ratios only apply to right triangles.

You can use the mnemonic "soh-cah-toa" to help you remember these ratios.

<u>First question</u>

For the first question, we're given the angle with a measure of 56 degrees and the length of the <em>hypotenuse</em>. We must calculate <em>a</em>, which represents the side <em>adjacent </em>to the given angle.

Given the hypotenuse and the adjacent side, we know that we must use the cosine ratio:

$\displaystyle cos\theta=\frac{adjacent}{hypotenuse}$

Plug in the given information:

$\displaystyle cos56=\frac{a}{13}$

Isolate <em>a</em> by multiplying both sides by 13:

$13\displaystyle cos56=a$

Solve using a calculator:

$a=7.3$

Therefore, <em>a</em> is equal to 7.3 when rounded to 1 decimal place.

<u>Other information you will need to know:</u>

In the above question, we needed to solve for a side. But what if we were given two sides and we needed to solve for an angle? For example:

$\displaystyle sin\theta=\frac{5}{8}$

In this case, we will use the inverse sine ratio:

$\displaystyle \theta=sin^-^1(\frac{5}{8})$

Solve using a calculator:

$\displaystyle \theta=39$

Therefore, the angle would equal approximately 39 degrees.

I hope this helps!
