dI(t) The voltage VL(t) across the inductor, where VL(t) = L · dt %3D The total voltage V(t) across the circuit.

y=√x Find dy/dt, given x = 4 and dx/dt = 3 Find dx/dt, given x = 49 and dy/dt = 8

A 100-W (watt) light bulb has resistance R = 143 2 (ohms) when attached to household current, where voltage varies as V = Vo sin(27ft), where Vo = 110 V, f = 60 Hz. The power supplied to the bulb is P = J/s (joules per second) and the R total energy expended over a time period [0, T] (in seconds) is T U = P(t) dt Compute U if the bulb remains on for 7 hours. (Use decimal notation. Give your answer to one decimal place.) U = J

Let C(t) be the daily cost in dollars per day to cool a house when the average outside temperature is t degrees Fahrenheit. What are the units of C'(95)?
