He got 15/16 because you have to take the (-1/4*V1i)^2. You square the (-1/4) to get (1/16) and when you move it over to the other side, you will get m1v1i^2 - (1/16)m1v1i^2 = m2v2f

Depending on the amount the mass is increased by, we can say that the force of the object is increase by x amount of mass. Example. If m2 = 3m1, a2 = a1 than F2=?F1 F2=m2a2 -> F2=3(m1)(a1) you see that (m1)(a1) is F1. In conclusion, F2 = 3F1.

Thank you. I was taking the inverse of (x+3)^3 + 2 and then I got stuck after that.

Got this one. Its 1/24 correct?

Are you possibly Steve Hawkins? Your getting this one after another.

That would be 1/(dy/dx) of x^2-4x+4 which would be 1/2x-4 correct?

well lets see. Since f^-1(x) = 9-x^2 then the derivative of 9-x^2 is -2x correct?

Wait f^-1(x) is 2sqrt(x) so then the derivative of that is 1/sqrt(x)

Yes, your answer is A as mentioned by Steve

Wrong. Its B The office building is designed with n floors and each floor is 3.9m right so you have right now: 3.9n On top of entire office building is a antenna which is 15.85m tall so its 3.9n + 15.85 = h

Inverse of sin(pi*cosx) = cos^(-1)((sin^(-1)(x))/pi) Derivative of cos^(-1)((sin^(-1)(x))/pi) is -1/(sqrt(1-x^2) sqrt(pi^2-sin^(-1)(x)^2))

derivative: sin(pi*cosx) = -pi sin(x) cos(pi cos(x))

You obvously didn't read it. The very first sentence in that post the Ms. Sue posted is "The universe was born with the Big Bang as an unimaginably hot, dense point." ... how did you miss that??

2 - 3 paragraphs down it says... "For the first 380,000 years or so, the universe was essentially too hot for light to shine, according to France's National Center of Space Research " Miss that too?

Thank you Ms. Sue
