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?
S-100 = t^2
-------
-16

S-100 = t^2
------
16

s - 100 = t^2
---
-16 or

S-100+16= t^2

I choose the last selection but I'm not sure I'm correct

3 answers

a. (s-100)/(-16)=t²
b. (s-100)/(16)=t²
c. s/16 -100 = t²
d. s-100+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:
(s-100) = -16t²
Divide by -16 on both sides to isolate t²:
(s-100)÷16 = t²

Now make your pick!
Sorry that there was a typo, but it would have been easier to post a follow-up if the answer did not work out.

"(s-100)÷(-16) = t²
Now make your pick!"
what is exemple of Binomial?
