If an object is projected upward into the air from ground level, then the height h(t) of the object in feet at time t in seconds is given by:
h(t) = -16t^2+ 344t
How long does it take for the object to hit the ground? SHOW ALL WORK clearly and neatly - do not skip
steps. The show all work part cannot be stressed enough.

21.5secs

Step-by-step explanation:

Given the function that models the height of an object as

h(t) = -16t^2+ 344t

The object hit the ground at h(t) = 0

Substitute

0 =  -16t^2+ 344t

16t^2 = 344t

16t = 344

t = 344/16

t =  21.5

Hence it takes 21.5secs for the object to hit the ground

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
