Answer:

Step-by-step explanation:

So, the point of this is to make x the only thing on one side, so we can see what x is!

Okay so first subtract 8 on both sides...

5x= 25

Now we need to divide on both sides!

That equals...

x=5

So now we know that x=5!

Hope this helped!! :D

Find the 30th derivative of y=cos(2x)
Sladkaya [172]

I got this answer from someone else so I’m not sure this is correct but I really hope it helps...

Step-by-step explanation:

Look for patterns in the derivatives.

y=cos2x

y'=-2sin2x

y''=-4cos2x

y'''=8sin2x

y''''=16cos2x

Notice that sin and cos alternate every derivative. Also, they alternate positive and negative every 2 derivatives.

The constant is just 2^(derivative#).

Every odd derivative has sin and every even derivative has cos, so you know that the 30th derivative will be cos.

If you follow the pattern of negatives and positives, you find that the 30th derivative will be negative.

y^(30)= -2^30cos2x

y^(30)= -1073741824cos2x

6/54 times because there are 9 marbles and the orange marble is 1 out of those 9 marbles. If you multiply 6*9= 54 then you notice there is a 6/54 chance of picking any 1 marble out of the 54 times that you decide to pick marbles.

Volume of cylinder=πr²h                 volume of another cylinder=πr²h       
=22/7×1.5×1.5×8                          =22/7×2.5×2.5×12    
=396/7                                         =1560/7   
=56.57                                         =235.71

=235.71-56.57
=179.14 amount of water is able to hold by the larger cylinder
