What is the height of an object thrown when time is 6 seconds? Also explain how u got your answer

nevsk [136]

Answer:

$946.4\ m$

Step-by-step explanation:

Let

h(t) ---> the height of an object in meters

t ----> the time in seconds

we have

$h(t)=-2.6t^2+40t+800$

For t=6 sec

substitute in the quadratic equation the value of t and solve for h

$h(6)=-2.6(6)^2+40(6)+800$

$h(6)=946.4\ m$
