The cost of the electricity if 42000 kWh of electricity is used is ; $1680
<h3>Determine the cost of electricity </h3>
<u>Given that ;</u>
value of electricity used = 42000 kWh
cost rate of electricity = $0.04/kWh
Final step : Determine the total cost of electricty used
unit cost = $0.04/kWh
Totals cost = unit cost * value of electricity used
= 0.04 * 42000 = $1680
Hence we can conclude that The cost of the electricity if 42000 kWh of electricity is used is ; $1680.

Answer:
C
Explanation:
When examining the trends in coastal position over a time frame, you perform shoreline change analysis. In most cases, coastal changes are very non-linear.A normal regression of the shoreline happens when there is supply of sediments where the base level is rising at the shoreline.Here the rate of sediment deposition is more than that at which the base level is rising at the shoreline.
The movement ofa shoreline seawards due to sedimentation at the coast is called regression.If this movement is due to sea-level fall like in our case in the question it is force regression.In option C, the sea level is falling.
