Answer:
i think its a trapazoid
Step-by-step explanation:
I don't Really know much about this stuff but I'm guessing its adjacent...
This is a quadratic equation whose graph is a parabola that opens down.
When does the rocket reach its highest point? Note that at that point it will stop ascending, momentarily stop, and then begin descending. Note also that that point is the vertex of the parabola.
The easiest way to find that time value is to use the formula t = -b/(2a).
Here, t at max height is t = -(144) / (2*[-16]) = 4.5 sec (answer.
What's the rocket's height there? To answer this, sub 4.5 sec for t in the given equation, <span>h(t) = -16t^2 + 144t.
Note: Please use " ^ " to indicate exponentiation:
</span> -16t^2 + 144t (not -16t2 + 144t)
