The wattage for three different types of lightbulbs is given in the table.

In the course of a month, each lightbulb is on for 730.5 hours. The electric company charges $0.15/kWh. Calculate the cost to run each lightbulb for a month. Round to the nearest cent.

Incandescent bulb: $_

CFL bulb: $_

LED bulb: $_

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
