In a root power that is made if the index is even?

Green Bay?

Well there are 5 squares total. so uh... um... brainfart....

Oh yeah:

You have 3/5 squares being purple so...

3/5 = 3:5

given tan x=-15/8 and sin x,xfind sin x

Sin x = (-15/8) / sqrt(1 + (-15/8)^2))

Sin x =(-15/8) / sqrt (1 + 3.515625)

Sin x = (-15/8) / 2.125

Sin x =- 1.875 / 2.125

Sin x = -0.882353....

3.687925 / 67 = 0.0550436567164179

67 / 3.687925 = 18.167397655863392

This was a toughy LOL

What is your team?

So if we know the answer is -5...

What divided by 3 is -5? -15. So lets continue.

-15 / 4 = -3.75. So now we must add 11.

11 + (-3.75) = 7.25

Is this correct?

Good question. Report it to the developer of the site.

We will use the distributive property for this:

-4(5x+3) = -4(5x) + -4(3) = -20x + -12

So your final Answer is -20x + -12, because there is no more to go!

Maybe someone can take it from here...

Notice that the series on the numerator is 1/2(e^x -e^(-x)  )    and on the denominator it's

1/2( e^x  + e^(-x)  )

At 100 or so terms, the function e^(-x) becomes so small that we can discount it and the function tends to

f(x) =cos(1/2 e^x   + sin(x) )    / sin( 1/2e^x    + cos (x) )

We are obviously not expected to differentiate it two thousand times.

The other thing I noticed is that ,under the Quotient rule,  (u/v)'   the denominator, v^2   will start appearing like this

f (1)   - first derivative   v^2 = sin^2(1/2 e^x + cos (x) )

f(2)   - second  " "          v^2= sin^4 (1/2 e^x + cos (x) )

f(3)                                         = sin^8 (  "  "     "                   )

f(4)                                          = sin^16(   " " "                 )

f(n)                                          = sin^ (2^n)  ( " " "             ) ie will numerically tend to zero

After a couple of thousand derivatives,the numerator will be such a long chain of sine and cosine products that it will numerically tend to zero and I agree with Alan that the integral is zero. (probably!)

I KNOW/believe the answer is Zero.

The function f is an even function.

The functions fⁿ alternate as odd and even.

f²⁰¹⁷ is an odd function since 2017 is odd.

The definite integral of an odd function over a symmetrical interval about zero is precisely Zero.

Unlike some people I take the time to type in the comma's.

What is Khan Academy?

Khan Academy is the one type of video sharing website. They give you knowledge from basic to advance in various subjects like Maths, Computer Science. It was founded by Salman Khan - A MIT Graduate from US. Even Google has given them lots of technical support as well as financial support.

Okay. I just like to always try to put the work and easiest way of equations into it.(Sorry about bad english.)

Actually no. She has always helped me and was the first to reply. But you're answer was good as well :)

Was my way to sophisticated? XDD

Thanks Isabelle!

1.

A: 3 x 4 x 5 = 3 x 4(12) x 5

So 12 x 5 = 60. (3 x 4 x 5 = 60)

2.

A: First, add 138 and 102 to get 240. Then divide 240 by 2 to get your answer! (138 + 102 = 240 / 2 = 120!)

1. 60 

2. Since the student chose a number let (x) be the number he chose:

2 * x - 138=102

2x=240

X=120 is the answer

Or:

Example: [(8, 6)(4, 7)]

[(8, 6)(4, 7)]

slope  =   [ subtract the y coordinates in some order ] /  [  subtract the x coordinates in the same order  ]

....so we have.....

slope  =   [7 - 6 ] / [ 4 - 8 ]  =    1 / - 4    =    -1 / 4
