I would have assummed they meant (cos(40))^2   read as cos squared 40 or cos 40 all squared

\(tan 40-9.8*20^2/(92*16^2*(cos(40))^2)\)

That would give 0.555471

But it is a guess at what the cos^2*40 meant

I love his music!!!!!!!

Depends if taxes are before or after.

1098.5*.75 = 823.88

199.99 *.65 = 129.99

129.9935+823.88 = 953.87

953.8735*1.195 = 1139.88

$1139.88

Yip B

This year is a decrease of 12% (-12/100 = -0.12)

 meaning it is now 88% (88/100 = 0.88)

With p being the previous year

B) p - 0.12p = 0.88p

Cos of what?

I'm gonna assume it is 40 with the tan

\(tan{40}-9.8(\frac{20^2}{92*16^2*cos^2{40}*40})\)

tan(40)-9.8(20^2/92*16^2*cos(40)*cos(40) *40) = -194075.942

-194075.942

B is the correct equation

how to do the cos-1 in the calculator ?? help me please!

((400*x)/400)/x+4)=100x

x/(x+4)=100x

1+x/4=100x

4+x=400x

399x=4

4/399 = 0.0100250626566416

x=0.0100250626566416

Hallo Guests!

r-8 1/3=4 2/5

r - (8 + 1/3) = (4 +2/5)

r = (4 + 2/5) + (8 + 1/3)

r = 4 + 8 + 2/5 + 1/3

r = 12 + (3*2 + 5*1) / 15

r = 12 + 11/15

Gruß asinus :- )

!

r=12 11/15

Avicii? I mean... he's pretty good.

You are a knight of the Radian Table. You must give your opinion or abstain.

I'm staying out of this one, Spawn.....LOL!!!!

Nay jk yay!!!

Definitely NOT linear.....!!!

Exponential  with a growth factor of  40.95 / 31.50   = 1.3

A is correct

≈

Do you mean that?

If so, that means approximately equal to.

For example, \(\pi\approx 3.14\).

Hope that helped!

V_pyramid =  [area of the base] * [height] / 3  =  [ 23m^2] * [12m] / 3  =  23 * 4  = 92 m^3

Well, this is all about adding the number that is before that number with your answer. 
FOR EXAMPLE:

1+1=2

2+1=3

3+2=5

5+3=8

and so on.

The nth Fibonacci number is given by :

F(n)  = [ Phi^n  - [-phi]^n ]  / √ 5 

Where  Phi  =  [  1 + √5] / 2

And phi  =  2 / [ 1 + √5 ]

4^4+1 = 257

You are correct, rarinstraw!

I have to check your work since you got the Pythagorean Theroems wrong.

Pi (π), the 16th letter of the Greek alphabet, is used to represent the most widely known mathematical constant. By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference is equal to pi times the diameter (c = πd). No matter how large or small a circle is, pi will always work out to be the same number.

Pi is an irrational number, which means that it is a real number with nonrepeating decimal expansion. It cannot be represented by an integer ratio and goes on forever, otherwise known as an infinite decimal. There is no exact value, seeing as the number does not end. Many mathematicians and math fans are interested in calculating pi to as many digits as possible. The Guinness World Record for reciting the most digits of pi belongs to Lu Chao of China, who has recited pi to more than 67,000 decimal places. The Pi-Search Page website has calculated it (with the help of a computer program) to 200 million digits.
