Question 1147199
.
<pre>

The formula for the height is


    h(t) = -16t^2 + 112t + 8.


The time to get the maximum height  is  t = {{{-b/(2a)}}} = {{{-112/(2*(-16))}}} = {{{112/32}}} = 3.5 seconds.


    I refer to the formula  x = {{{-b/(2a)}}}  for the general form quadratic function y = ax^2 + bx + c.



The maximum height you can get  by substituting this value of time t= 3.5 seconds into the formula (1)


    h(3.5) = -16*3.5^2 + 112*3.5 + 8.


Use your calculator.
