Homework Statement Two curves are perpendicular f(x)= x-4/x and h(x)= x+2/x^2-4x intersect at (2,-1). How would i find if they are perpendicular i first found the derivative of the equations by using the quotient rule but i do not know what to do next.

Homework Statement I am given 3 planes 1) (3-a)x-2y-4z=0 2)-2x-(2+a)y+6z=0 3) 4x+6y-(1+a)z=0 The Attempt at a Solution So what i did was i expanded the equation 1) 3x-xa-2y-4z=0 2)-2x-27-ya+6z=0 3)4x+6y-z+az=0 and i used the elimination method using 3x-xa-2y-4z=0...

Homework Statement I did a lab where there was a glass tube with a rubber ball attached and a string hanging from the glass tube with metal washers attached at the bottom. My question is if the ball were to hang too low why would the centripetal force be less accurate is it because there...
