Answer:
![946.4\ m](https://tex.z-dn.net/?f=946.4%5C%20m)
Step-by-step explanation:
Let
h(t) ---> the height of an object in meters
t ----> the time in seconds
we have
![h(t)=-2.6t^2+40t+800](https://tex.z-dn.net/?f=h%28t%29%3D-2.6t%5E2%2B40t%2B800)
For t=6 sec
substitute in the quadratic equation the value of t and solve for h
![h(6)=-2.6(6)^2+40(6)+800](https://tex.z-dn.net/?f=h%286%29%3D-2.6%286%29%5E2%2B40%286%29%2B800)
![h(6)=946.4\ m](https://tex.z-dn.net/?f=h%286%29%3D946.4%5C%20m)
