Question

The surface area of an oil spill gets 105% larger every day, represented by the function s(x) = (1.05)x − 1. On the first day, it covered an area of 31 square meters. Which function would be used to find the area of the oil spill on the 15th day?

Answer 1

f(d) = 31 × 1.05^(t-1)

31(1.05^(15-1))

61.3778795826
