Question

Evaluate the following expression it using the values given find 2x-3y-x if x=-3,y=2, and z=-2

Answer 1

= 2(-3) - 3(2) - (-3)
= -6 - 6 + 3
= -12 + 3
= -9

Answer 2

an RC circuit has an emf of 10 sin t volts, a resistance of 100 ohms, a capacitance of 0.005 farad, and no initial charge on the capacitor.
Find (a) the charge on the capacitor at any time t and (b) the steady-state current.
