It is "asin"

Arcsine is the same as inverse sine.

$$\pi$$ is a constant that is equal to the circumference of any given circle divided by the diameter of said circle.

=3.39km

=3.3km

value of pie is 14.16

You are on the right track!

4a + 3b = 22    ...(1)

5a - 4b = 43     ...(2)

Multiply (1) by 4 and (2) by 3 (as you did):

16a + 12b = 88   ...(3)

15a - 12b = 129  ...(4)

Add (3) and (4)

31a = 217          ...(5)

Divide both sides of (5) by 31

a = 7                 ...(6)

Substitute (6) into (1)

4*7 + 3b = 22

Subtract 28  (=4*7) from both sides

3b = -6

Divide both sides by 3

b = -2

By taking out a common factor they mean getting rid of a common factor, 4, 12 and 8 can all be divided by 4:

$$4x^2-12x+8=4(x^2-3x+2)$$

$$4(x^2-3x+2)=4(x-2)(x-1)$$

Hope this helps.

Thanks Honga,

Do you understand Rosala?

30/6 = 5        100%/5 = 20% 

Its gonna be 20%

$$\\
\sqrt{0.09}*0.9*x=0.9*0.09*\sqrt{y}\\\\
\sqrt{0.09}*x=0.09*\sqrt{y}\\\\
\frac{x}{\sqrt{y}}=\frac{0.09}{\sqrt{0.09}}\\\\
\frac{x}{\sqrt{y}}=\sqrt{0.09}\\\\
\frac{x}{y}=\frac{\sqrt{0.09}}{\sqrt{y}}$$

The original function isn't a linear equation, hence it is impossible to get $$\frac{x}{y}$$ on one side without having some form of x or y on the other.

so we'd solve this like 

6+(-4)= (-4)+6  (now to solve this , lets break it into two parts L.H.S ( Left Hand Side) and RHS (Right Hand Side) ]

LHS = 6+ (-4)          (and now out here we will change the plus and minus sign to just minus sign and then subtract them both simply)

= 6 - 4 

=2   ANSWER

and now we will solve RHS

RHS= (-4)+6           (here we just have to mopen the brckets of -4 and subtract)

= -4+6

= 2    ANSWER

so.......LHS is equal to RHS so the final answer would be

2=2 ANSWER 

i hope u've understood by now but if not then pls be free to ask!

hope this helps!

You can enter D + M/60 + S/3600 as there are 60 minutes in a degree and 3600 seconds in a degree.  The result will be in degrees.

ln(8 - 4x) - ln(x²) = ln(4)

Using the property of logarithms that ln(a) - ln(b) = ln(a/b) we have

ln((8-4x)/x²) = ln(4)

This means we must have

(8 - 4x)/x² = 4

Multiply both sides by x²

8 - 4x = 4x²

Divide through by 4 and rearrange

x² + x - 2 = 0

This factorizes nicely as

(x - 1)*(x + 2) = 0

So the solutions are x = 1 and x = -2

thats very helpful Aziz!i should better thank you for that!thanks!and a point for u aswell!

Thank for that way Aziz but i dont have that problem anymore!and if i'd have i'd check out for your way!thanks again!

your Welcome Aziz!im glad you like my laughs!and yeah i had found some funy movie pics so just wanted to add them aswell!And my favorite one is the first one of Ron, besides being really young and cute he's funny aswell insome ways!lol!

Your Welcome Aziz!And yes teachers deserve the best!They r really hardworking!first , teaching us everything , second , preparing test papers for us n third correcting n giving us marks in the exams or tests!

there r some teachers in the school whom i really like , theres one teacher who taught me to be confident and made me strong n not just give up on something easily and not be weak!and theres one very sweet very kind n polite teacher in my school who i call the best one , she's always kind and after talking to her i feel really nice and even by seeing her pass just makes my day!

It doesn't exist.

$$\lim_{x\rightarrow \infty}(e^{-x}+2\cos{3x})=\lim_{x\rightarrow \infty}(e^{-x})+\lim_{x\rightarrow \infty}(2\cos{3x})=0+\lim_{x\rightarrow \infty}(2\cos{3x})$$

The limit of cos(3x) as x goes to infinity is undefined as cos(3x) continues to oscillate between maximum and minimum values of 1 and -1 forever.

Thank you so much for the help and clarification. (:

Thanks, Alan! The partition theory sure is detailed! 

Yep, DS, well at least we learn something new each time. 

(a) Set up a proportion:

$70/35 people = x/10,000 people

Now, cross multiply:

35x = 700,000

x = 700,000/35 = $20,000.

Note: It is easier to see that they gain revenue that is 2 times more than the number of people so 10,000 people should give the company $20,000.

(b) If 10,000 people --> $20,000

30,000 people --> 3*($20,000) = $60,000.

THANK YOU!(:

12 / (-4/9) - 27

First, we perform 12 / (-4/9):

Remember: skip, change, & flip

12 * (-9/4)

We can simplify the 12 and 4 to 3 and 1 by dividing by 4:

3 * -9/1 = -27.

Now, we have to subtract 27:

-27 - 27 = -54.

-54 is the final answer.

Me too. I will give you half the money if it's correct...

Hook might be correct but not sure. I was thinking door since you have to pass a door each time you go from one room to another unless you have no doors but just an entirely open home.

Yep, Google Chrome is the best! Works great with minimal issues! It could be that you need to completely clear the cache, update to the latest version, or see if your settings may be messing with it!
