An object which is dropped from 100 feet above ground falls according to the formula s = 16t^2 + 100, where s is the distance from ground level at time t.
Which equation is equivalent to this formula?
S100 = t^2

16
S100 = t^2

16
s  100 = t^2

16 or
S100+16= t^2
I choose the last selection but I'm not sure I'm correct

MathMate
a. (s100)/(16)=t²
b. (s100)/(16)=t²
c. s/16 100 = t²
d. s100+16=t²
The last choice is definitely incorrect, here's why:
Given
s = 16t^2 + 100
we need to express t² in terms of s.
subtract 100 from each side to get:
(s100) = 16t²
Divide by 16 on both sides to isolate t²:
(s100)÷16 = t²
Now make your pick!

Sorry that there was a typo, but it would have been easier to post a followup if the answer did not work out.
"(s100)÷(16) = t²
Now make your pick!"
