#3 Which of the following is less than 527 m?
A. 0.000699 Mm = 0.000699 · 1,000,000 m = <u>699 m</u>
B. 914,879,710 nm = (914,879,710 : 1,000,000,000) m = <u>0.914879710 m</u>
C. 51,723 cm = (51,723 : 100) m = <u>517.23 m</u>
The best answer is C
#4 How many songs would you have if the average file size is 4,000 kb?
8 gb: 1,700 songs
16 gb: 6,000 songs
2 gb: 500 songs
160 gb: 30,000 songs
64 gb: 14,000 songs
1 Terabyte = 1024 gb: so im guessing 350,000 songs
This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).
F(x) = x - 2sinx
To find for what values of x graph has tangents we need to differentiate function f(x).
f'(x) = 1-2cosx
Now, if we want to have horizontal tangents we need to make function f'(x) equal to 0 because at minimum or maximum of function f(x) tangent is horizontal.
1-2cosx = 0
cosx = 1/2
x = pi/3 + 2*n*pi and
x = -pi/3 + 2*n*pi
Explanation: cosx = 1/2 for both 60° and -60°. If we make one circle cosx will be equal to 1/2 for 420 and 300 degrees. Writing degrees in radians (using pi) we can write formulas above where 2*pi represents one full circle and n is an integer which represents how many circles we made.

i do not know the answer to this question sorry about that
Answer:
The answers are 
and 
.
Step-by-step explanation:
Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.
First, let's begin with 2:
Then, let's do 5:
Note that we already have 
, so we do not need to include an additional one.
Now, let us do 8:
See how we already have 
, so we won't have to include that as well.
Finally, let's do 20:
Now see that we already have both 
and 
, so we won't have to include both of them, as they are both extras.
Hence, the answers are and .
