Question

The surface area of an oil spill gets 115% larger every day, represented by the function s(x) = (1.15)x − 1. On the first day, it covered an area of 43 square meters. Which function would be used to find the area of the oil spill on the 23rd day?

Answer 1

s(x) = 43(1.15)^(x − 1)

Explanation:

Answer 2

This is the concept of algebra; We are required to find the function that will represent the given information;
Given that the function representing the surface area is s(x)=(1.15)x-1
the initial area of oil is 43 m^2.
since we have to put the initial area into our function, our new expression will be:
s(x)=43(1.15)x-1

the answer is s(x)=43(1.15)x-1
