Question 1129339: When a softball player swings a bat, the amount of energy E(t), in joules, that is transferred to the bat can be approximated by the function
E(t) = −279.67t2 + 82.86t
where 0 ≤ t ≤ 0.3 and t is measured in seconds. According to this model, what is the maximum energy of the bat? Round to the nearest tenth of a joule.____joule

is just a parabola. I'm sure you know how to find the vertex, where is a maximum.
where 0 ≤ t ≤ 0.3
......complete square to get vertex form
max ate vertex: (, )=(, )
so, , round to the nearest tenth of a joule:
joule
