Best ResponseYou've already chosen the best response.0Using the same H(t) formula from the last one H(t) = 16t² + vt + s, what's v and what's s?

Best ResponseYou've already chosen the best response.0yep, so we have H(t) = 16t² + 42t so now we just need to find the vertex. For a quadratic function in the form \[y=ax^2+bx+c\] the vertex is \[\left( \frac{ b }{ 2a },f \left( \frac{ b }{ 2a } \right) \right)\] We have a = 16, b = 42, and c = 0 So for the time, find \[t=\frac{ 42 }{ 2*16 }\] Then plug it into our function to get the max height

Best ResponseYou've already chosen the best response.0ok so it would be h(t)=16t^2 + 42t and substitute 1.31 for t?
