Just multiply out the terms on the right hand side to get a 4th order polynomial, each term of which is simple to integrate.

omg thank u so much

what is 2y^2-2y

=2y (y-1), its values are y=0   and   y=1

So, why don't you use it?

Let the first digit be x

Let the second digit be y, then we have:

(10x + y) / 2 X 9=(10y + x), there is only one solution for a two-digit number:

It turns out that x=1 and y=8, so the number is:18 because,

18/2 X 9=81, which when reversed you get the original number of 18

So 90825000 in scientific notation would be 9.0825 x 10⁷. You move the decimal and multiply by 10 to whatever power u move the decimal. in this case you move it 10 places so it is 10^7

Volume of cylinder: V=Pi.r^2.h                                        

V=3.141592653 X (16.5/2)^2 X 1.26=269.419mm^3 volume of $5 coin,

269.419/1000=.269419cm^3

Density=3.393/.269419=12.594gm/cm^3 density of $5 coin.

V=3.141592653 X (32.70/2)^2 X 2.87=2,410.279mm^3 volume of $50 coin,

2,410.279/1000=2.410279cm^3

Density=33.931/2.410279=14.078gm/cm^3 density of $50 coin

The $50 coin is denser by about 1.5gm/cm^3. So, the difference in density is significant despite the uncertainty given in the table. There is no overlapping uncertainty.

You = dead

'Evaluate the function' for t= 1   means what is the value of this function when t = 1   (or t= 2 or t= 4   etc)..... so yes,   put '1' in for 't' and see what value results....that is it!   You did it!

You pretty much know the answer....if you need km/hr just divide it out....you have km and you have hours......right?

km/hr  in this problem    is   ????

12 km  /  2 hr  =======??

6  km/hr

3 times

2/3  = 2 divided by 3.....just use your calculator for the answer.

100.000 + 200.000

= 300.000

x is a variable.

x can be anything, such as 1, or 2, or even 50.

Saying x2 simply means you are taking x and multiplying it by 2.

So if x was 3, x2 would be 6.

Or if x was 7, x2 would be 14.

It's preferred to write it as 2x, though, with the algebraic variable written after the coefficient (ordinary number).

Yeah that's correct.

• -1^3-1 = 0
• 0^3-1 = -1
• 1^3-1 = 0
• 2^3-1 = 7
• 3^3-1 = 26

Generally means either 2x or 2 times bigger that something else.

NOT AS DUMB AS YOU ARE! ASK YOUR FRIENDS.

Just get Zips on your Math tests!!!.

what is 25*1,35^x=502,67 ? How do i find the x ?

25 X 1.35^x=502.67 divide both sides by 25

1.35x=20.1068 take the log of both sides

x = Log (20.1068) / Log(1.35)

x=10 very nearly.

Give us an example of what you want to do.

You should attempt to type your questions instead of givings us copies of hand-written scribbles that we cannot copy and paste. And we have to decipher your hand writing and re-type it again!. Type it and don't be lazy. How many people on this site do what you do? If you don't get any responses to your questions, that is the reason why.

Any one?  

what is 0.95m=__3.12______ft

x is invested in CD's @ 7%, then we have:

(190,000 - x) is invested in AA bonds. But, we have:

.07x + .10(190,000-x)=17,200

.07x + 19,000 - .1x=17,200

-.03x=-1,800

x=$60,000 is to be invested in CD's @ 7%, and $ $190,000-$60,000

=$130,000 is to be invested in AA bonds @ 10%
