Question

The surface area of an oil spill gets 131% larger every day, represented by the function s(x) = (1.31)x − 1. On the first day, it covered an area of 21 square meters. Which function would be used to find the area of the oil spill on the 47th day?

A. s(x) = (1.31)21 − 1
B. s(x) = 21(1.31)x − 1
C. s(x) = (1.31)x − 21
D. s(x) = 1.31(21)x − 1

Answer 1

I KNOW YOU

Answer 2

do you?

Answer 3

S(x) = 21(1.31) ^(x -1)

Day 1

s(1) = 21 (1.31)^(0) = 21

Day 47

s(47) = 21(1.31)^46

Answer: 21(1.31)^4
