Does the rate of change equal for each.
take the output difference and divide by the input distance
1st -5/10 = -1/2
2nd -1/2
3rd -5/10.= -1/2
X=((log(225000/200000)/log(1.03))
X=log(225,000÷200,000)÷log(1.03)
X=3.98 years
Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
1/6 = 0.1666, the last number repeating to infinity, or a repeating decimal.
