Algebra
Ok well bobpursley first of all your a genius ;) second of all im a newbie at this logorithm stuff. thank you for helping me!

Algebra
Expand the expression of log5x^(1/3)y^6 5 is the base of the log. this is pretty tricky stuff and im not sure how to attempt it..

Algebra
Solve the equation and check for extraneous solutions. 10^((x^2)+1)=100,000 How do i handle this when the exponents have exponents?

Algebra
Find a power function of the form y=ax^b whose graph passes throught the points (2, 5) and (8, 12). How do i solve this??

I got that vi=10.29 then when I sub in I get that v=11.23 but this is the wrong answer. Am I doing something wrong?

Please Help!!! A 920 kg sports car collides into the rear end of a 2300 kg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.5 m before stopping. The police officer, knowing that the coefficient of kinetic friction between tir...

Physics
Suppose the roller coaster in Fig. 6-41 (h1 = 30 m, h2 = 11 m, h3 = 20) passes point 1 with a speed of 2.10 m/s. If the average force of friction is equal to one fifth of its weight, with what speed will it reach point 2? The distance traveled is 50.0 m.

Physics
A child in a boat throws a 5.40 kg package out horizontally with a speed of 10.0 m/s, Fig. 7-31. Calculate the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 25.0 kg and that of the boat is 40.0 kg.
