Since sin x can't be bigger than 1, assuming this is the question

cos (2x + 2) = sin x

*edit* That was a bad thing to assume! 

This is probably not the answer you want.. see CPhill's answer vvvv

But if you did happen to mean that:

This is to make it easier to see that

x + (2x + 2) = 90

x + 2x + 2 = 90

3x = 88

x = 88/3

i asked why is bread bread, not a wikipedia definition of bread

I think you're missing something, here......there's nothing to prove....

If  y'  =   4y   .....  then.......

dy / dx   =  4y       this is a separable equation

dy / y  =  4 dx      integrate both sides

∫ 1/y    dy     =   ∫ 4 dx

ln y    =   4x  + C          exponentiate both sides

e^(ln y)  =  e^(4x + C)  

y   =   e^C * e^(4x)  = Ce^(4x)

And we have that  y(0)  = 1 .....so.....

1  =  Ce^(4 * 0)

1  = C

And  when y  =4

  4 =  e^(4*x)       take the Ln  of both sides

Ln 4   =  Ln e^(4x)

Ln 4  = (4x) Ln e

Ln 4  =  4x     divide both sides by 4

Ln 4 / 4   =  x   ≈  .34657

5 cheerios + 2 cheerios = 7 cheerios

5 tenths + 2 tenths = 7 tenths

5/10 + 2/10 = 7/10

Is this the question:   \(\frac{\sin x}{\cos x} (2\cos x -1 )\)

Or

Is this the question:   \(\frac{\sin x}{\cos x (2\cos x -1)}\)

[10C10 + 10C9 + 10C8 + 10C7 + 10C6 + 10C5] =[1+10+45+120+210+252]=638/2^10=0.623046875=62.30%

sin (2x)  = 1

Let   2x  = θ

sin (θ)  = 1      at     θ  =  pi/2  + 2pi*n

So

2x  =   pi/2  + 2pi*n         divide by 2

x  =   pi/4  + pi* n             where n is an integer

sin (pi + x)   -  sin (pi - x)

[ sin pi *  cos x  + sin x * cos pi ]  - [ sin pi * cos x  -  sin x  * cos pi ]  =

2sin x * cos pi   =

2sinx * -1

-2sin x

What did you come to this website for if not for calculating 24/4

h=-16t^2+25 find the height and time for the projectile motion equation

h=-16t^2+25 

h'=-32t

h''=-32

Assuming that this is on earth, I can see that you question is in feet and seconds :)

maximum height is where h'=0 which is when t=0

The projection starts at a height of 25 feet.

so something is being dropped or thrown downwards.

I assume it will hit the ground when h=0

h=0 when 

-16t^2+25 =0

16t^2=25 

t^2=25/16 

t=5/4

It will hit the ground in 1.25 seconds  

This is what I got:

\(3\frac14*3\frac14*3\frac14=\frac{13}{4}*\frac{13}{4}*\frac{13}{4}=\frac{2197}{64}\)

tan^2 θ  * csc θ   +  (1 / sin θ)

[sin^2 θ / cos^2 θ] * (1/ sin θ) + (1 /sin θ)     factor out  1 / sin θ

1 / sin θ  [  sin ^2 θ / cos^2θ   +  1 ]  =

1/sin θ [  (sin^2θ + cos^2θ] / cos^2θ  =

1/sin θ  [ 1 / cos^2 θ ]  =

cscθ * sec^2 θ  =

sec^2 θ csc θ

\(4\frac45=4.8 \\~\\ 4.8 * 100 = 480\)

4 and 4/5 = 480 %

0.15 * 2.0 million = 0.3 million = 300,000

the answer is 19

the answer is 507/64 (the slash is a fraction bar)

\(6\frac23\times1\frac14\)

Convert the mixed numbers into improper fractions.

\(\frac{20}{3}\times\frac{5}{4}\)

Multply straight across.

\(\frac{20\times5}{3\times4} \\~\\ \frac{100}{12}\)

Reduce.

\(\frac{25}{3}\)

If you need it as a mixed number that is = \(8\frac13\)

P(three straight)   =  .72^3  ≈  .373 =  37.3%

thanks guys

the answer is 6

24 ÷ 4 = 6
