Answer:
[tex]946.4\ m[/tex]
Step-by-step explanation:
Let
h(t) ---> the height of an object in meters
t ----> the time in seconds
we have
[tex]h(t)=-2.6t^2+40t+800[/tex]
For t=6 sec
substitute in the quadratic equation the value of t and solve for h
[tex]h(6)=-2.6(6)^2+40(6)+800[/tex]
[tex]h(6)=946.4\ m[/tex]
