Find the unit rate round to the nearest hundredth calculator $170 for 14ft2

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
