Duh!! Twenty minutes too.

I understand that much, but I still cannot derive the curvation equation.. a.Let x prime and x double prime be the first derivative and second derivatives of x with respect to t, and similarly for y. Show the following in true. dƒ³/ds = ( xŒ yŒŒ - xŒŒ yŒ ) / (vector V)^3

Wow that did not work... Prove (dphi/ds) = ( xprime*ydouble prime - xdoubleprime*yprime ) / (vector V)^3

I am trying to prove the formula..

1.049 and .9982 respectively.

its a triangle on a table with an unknown angle. the two masses are connected by a string.

Can you check if I have right now?

for no 1) I'm confused the data is: 86 96 88 91 which = 361 with a test score of 99 added in its; 86 96 88 91 and 99 = 460 /5 = 92% and i don't understand how you get 3 meters i got -3 meters -2-1= -2 + -1 = -3

OK SO 1ST ONE IS 99 I Still don't understand how its +3 difference? can you explain?

Would PV=nRT apply to this? if so, how do I find "n"?

What is the molarity of a sodium chloride solution if 31.0 grams of sodium chloride is added to enough water to make 1.84 liters of solution?

Chemical bond formation

i'd go with D.

A) F = 0.0016YA, F= 1600N B) Delta L = FL/AY, Delta L = 0.0064 m or 6.4 mm C) F = 0.0065YA, F = 6500N ----------------------------------------- Just did this problem and it's correct, I got'chu.

please help fast guys.

It is D

Vf^2=Vi^2+2ad Vf^2=0^2+2(9.8)(1.25) 4.94974

Is there anything else I could included?

I would use the first way and then subtract ur like terms and simplify, if u want u can give it a try and I can check your work

You should graph your points first and then use your translations. When you reflect on the y axis, u Multiply your x values by -1 (check to make sure) and then once you have competed that simply move your points left 3 units and down 6 units and then you will have your new points

Ok thanks :)

Thank u very much, I was also confused cause I didn't understand why we needed complex numbers :)

incorect it should be 1/3 because it has "greater than 3"

The answer was "Informal and Simple"!! Ahhh that sucks :/

If you mean that they have 138 pie cylinders and need 6 per kit, how many kits will they be able to make? Then you would just need to divide 138 by 6, which will come up to 23. They can make 23 kits that include 6 of the pie cylinders.

Since you are adding a positive fraction to a negative fraction, the equation changes to subtraction. 9/13 - 2/15. Do the math and you come out with 109/195 (0.558974)

Thank you Ms. Sue! I agree with you on number 2, I reread the story and it made more sense. Have you ever read "The Censors"?

I dont think either A or B are correct. If anything I'm guessing it is C, because often children rebel against time-outs.

Do you have the rest of the answers?

303 kJ

B = 3J - 450g J = 225g 225 x 3 = 675g 675g - 450g = 225g (Jessies weight) Therefore Buzz must weigh 675g

It’s 67 feet option B

So if it's 7.5946 would we round it up to 8 or would it just be 7?

I'm so confused
