Best ResponseYou've already chosen the best response.0like @Jack1 did, or you could firstly work out the gradient, and substitute the values into a point gradient formula.

Best ResponseYou've already chosen the best response.2hmmm... k k well idk how else to do it, sorry so: \(\Large y = 16x^2 +15 +110x\) \(\Large y = 16x^{\color{red}{2}} +110x^{\color{blue}{1}} +15x^\color{green}{0}\) \(\Large y' = \color{red}{2} \times16x^{\color{red}{2}1} + \color{blue}{1} \times 110x^{\color{blue}{1}1} +\color{green}{0} \times 15x^{\color{green}{0}1} \) \(\Large y' = \color{red}{32x^1} + \color{blue}{110x^0} + \color{green}{0}\) \(\Large y' = \color{red}{32x^1} + \color{blue}{110} \) this is the gradient

Best ResponseYou've already chosen the best response.2\(\large y′=−32x+110\) gradient = 0 at the turning point (highest point) \(\large 0=−32x+110\) \(\large 110=−32x\) \(\large 110/32=x\) so the time it takes to get to the highest point = 110/32 = 3.44 seconds (ish)

Best ResponseYou've already chosen the best response.2nah, chill, all good, i'm makin snacks now too, freakin starving sweet, so if it reaches the peak ht at 3.44 seconds... how long from when its fired to when it hits the ground?

Best ResponseYou've already chosen the best response.2yep, a to prove: just plug x =3.44 into first equation y=−16x2+15+110x y = height = 204.06

Best ResponseYou've already chosen the best response.2b) ??? maybe, will try.... so the difference each time is 3 7... 3 = 4... 3 = 1... 3 = 2... etc... but it's supposed to be recursive... so doesnt that mean it eventually comes back to 7?

Best ResponseYou've already chosen the best response.0Recursion is the process of choosing a starting term and repeatedly applying the same process to each term to arrive at the following term. Recursion requires that you know the value of the term immediately before the term you are trying to find.
