Name 2 characteristics of the Polar Coordinate System.

A pole is the point in a polar coordinate system used as a reference. The polar axis is a fixed ray with origin at the pole, usually horizontal, from which an angle can be established. A polar coordinate is an ordered pair of numbers (r, θ) which represents a point in the polar coordinate system, where if r is the distance from the point to the pole and θ is the angle formed between the polar axis and a ray extending from the pole through the point.

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
