O yea, I forgot about that. Duh. Thank you so much

Those formulas in problem 2 are some of the answer choices of that multiple choice question

1. Find y' if xey + 1 = xy The attempt at a solution I separated the y: y= ey + 1/x After deriviation: y' = e2(dy/dx) -1/(x2) Is this correct? If so, how do solve after since this question is m/c which one of choices is (y-ey)/ (xey-1), though it could be none of above. 2. Find...

Homework Statement I need to intergrate the following (4x2+2x-1)/ (x3+x2) How to set up problem using linear factors? The Attempt at a Solution Factoring the denominator I get: x2(x+1) By linear/quadratic factoring I get: A/x + Bx+C/ x2 + d/(x+1) Is this right?

1. If the INternational space station has an orbital velocity of 9,000 m/s. find the time (in minutes) it takes to make one complete orbit. Relevant equations F = mv2/ R = m4[pi]2R / T2 The attempt at a solution Is this the way to solve for T? Do I use Earth mass and Earth R b/c that...

1. A 1.0 kg mass moving with a velocity v m/s strikes a stationary mass (assume no frictional losses). a. Is it possible for both masses to move in the same direction and at the same speed after the collision? If so, find the value of the stationary mass. b. Is it possible for both masses to...

I have two problems that I got confused with and I am not sure if I am doing right Homework Statement 1) The starship ENTERPRISE 1200m long when at rest. How long would it seem to be to someone watching the ship pass by them at 0.75c? Homework Equations length contraction \Delta...
