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?

I believe s(x) = (1.05)x - 15

anonymous · Answer

that's not one of the options :/


 s(x) = (1.05)31 − 1 

 s(x) = 31(1.05)x − 1 

 s(x) = 1.05(31)x − 1 

 s(x) = (1.05)x − 31

i think its d

does anyone know for sure? I think its d too but idk

anonymous · Answer

I would say B, but I'm still trying to formulate a reason for it.

Is it $s(x)=1.05^x-1$ or $s(x)=1.05x-1$?

ok just let me know when someone knows for sure because I want to get a good grade on this but theres another pn 

 Every day, there are 4 times more likes on an internet video of a horse which is modeled by the function c(n) = (4)n − 1, where n is the number of days since the video posted. On the first day, there were 100 likes. What is the function that shows the number of likes each day?
