kotegsom [21]

Answer:

the answer is the option B

$18.84\ m$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have

$r=3\ m$

$\pi=3.14$

substitute the values

$C=2(3.14)(3)=18.84\ m$

Can someone help with this one???

Answers:

128 subsets

127 proper subsets

=======================================================

Explanation:

Set P is the set of letters from the word "PREPOSTEROUS"

So P = {P,R,E,P,O,S,T,E,R,O,U,S}

But we must toss out any duplicate items. After doing so we have

P = {P, R, E, O, S, T, U}

which in alphabetical order would be

P = {E, O, P, R, S, T, U}

There are n = 7 unique letters in this set.

So there are 2^n = 2^7 = 128 subsets and (2^n)-1 = (2^7)-1 = 128-1 = 127 proper subsets.

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

note: If B is a subset of A, then everything inside B is also inside A. But not necessarily the other way around. A proper subset is one where set B is smaller than set A (it has at least one fewer items).

Hi!

what you do is you move all the numbers on one side of the equal sign and the variable on the other side, when you move the numbers the switch signs

so it will look like

-2n=2-4

-2n=-2

drop the minus

2n = 2

n =1
