Study Notes

Checkpoint C is located directly east of Checkpoint A.
The bearing from Checkpoint A to Checkpoint B is N22°E.
The bearing from Checkpoint B to Checkpoint C is S68°E.
Distance between Checkpoint A and Checkpoint B is 42 km.
Determine values of h and x to the nearest centimeter.

Runner's Travel Time

Runner's speed is 12.6 km/h.
Calculate travel time between Checkpoint A and Checkpoint B in hours and minutes.

Electricity Providers Comparison

Provider A charges 25 cents per kilowatt hour (kWh) plus a $40 fixed monthly fee.
Provider B charges 35 cents per kWh with no fixed monthly fee.
A table is needed to calculate monthly charges for Provider A at different levels of usage.
A graph should be created to depict charges from Provider B based on usage.
Compare the two graphs to identify the point where both providers charge the same amount for kWh usage.
For a usage of 800 kWh per month, analyze which provider offers a more economical option and calculate the cost difference.

Description
