random math queastion
√x^2+2 Is this possible as is?

Physics
An 52.0 N box of clothes is pulled 7.3 m up a 30.0° ramp by a force of 103 N that points along the ramp. If the coefficient of kinetic friction between the box and the ramp is 0.22, calculate the change in the box's kinetic energy.

Nevermind!! I got it! Thank you so much

I got 571, but it says it's wrong!!

Calculus
when I plug in the ordered pair (.25, 2)I get a zero in the denominator, was I doing that wrong?

arcsinxy = 2/3 arctan4x find dy/dx at the point (1/4, 2)

name a possible set of scores for 15 students that would result in an average of 66%

y=-2|x| actually I'm sorry I left some of the details out. It says to let x=-3,-2,-1,0,1,2 and 3. Not sure what to make of this..

colleGe math
y=-2|-3| was the intended equation
