55. A cell tower is a site where antennas, transmitters, andreceivers are placed to create a cellular network.Suppose that a cell tower is located at a point A(4, 6)on a map and its range is 1.5 mi. Write an equationthat represents the boundary of the area that canreceive a signal from the tower. Assume that alldistances are in miles.

Given: Point A is (4,6). The range of the tower is 1.5 mi.

Answered: 55. A cell tower is a site where…

a) A typical small passenger electric vehicle has a range of 200 km on an electric charge of 33 kWh. Convert this number into J/km (Joules per kilometer traveled). b) A comparably sized gasoline powered vehicle to (a) is rated as 25 miles per gallon. Convert this number into J/km (Joules per kilometer traveled). c) If gasoline costs $10.00 per gallon, and electricity $0.30 per kWh what is the difference in the cost of fuel per kilometer travelled between the electric vehicle in (a) and the gasoline powered vehicle in (b)? d) Surveys of EV owners show that they charge at home 70% of the time. Let us assume that for the remaining 30% they charge at a 60 kW rated "fast-charge” station. If patterns of travel remain the same, but we swap all our gasoline vehicles for electric vehicles, what is the ratio between installation of fast charging stations to gasoline pumps retired. e) The Chicago Transit Authority has about 2700 buses that travel a total of 240,000 miles daily.
