A professional football team uses computers to describe the projectile motion of a football when punted. After compiling data from several games,
the computer models the height of an average punt with the equation
h(t) = ((-16)/3)(t - 2.2)^2 + 26.9
where t is the time in seconds and h(t) is the height in yards. The punter’s
foot makes contact with the ball when t = 0.
1. Find h(3) and explain the meaning of this value.
2. When does the punt reach its highest point? How high does the
football go?
3. For how long is the football in the air before it hits the ground? Use an
algebraic approach.
4. How high is the football when the punter kicks it? Show your work.
5. For how long is the football in the air at a height of at least 20 yards?
Use an algebraic approach and justify your answer.

answer:

some responsibilities that come with having a checking account -

1. we have to maintain check register with exactness to avoid checks being returned for insufficient funds which is called bouncing a check.

2. we need to update our check register each time we make a transaction using a convenience card. updating check register will   save   us from   overdrawing of checking account.
