Answer:
x = -8 & x = 3
Step-by-step explanation:
Vertical asymptote occur when denominator is 0.
So to find the x-values, we need to middle term factor the denominator. Shown below:

Thus, at x = 3 and at x = -8 -- there is vertical asymptote.
5 i think because 50 is 25 and 25 is 5
I would think that thwe equation used to solve it would be 0.2 - r = s.
For part A just plug the numbers 2 through 5 for t for both function and see what numbers r the same and for part b it means that the two baseballs r gonna have the same height after t seconds
