Part (a)
t = time in seconds
h(t) = height of the rocket
The general projectile equation is
h(t) = -16t^2 + vt + k
where v is the starting or initial velocity (in this case v = 64) and k is the starting height (k = 0 in this case)
Therefore, the equation is h(t) = -16t^2 + 64t
==================================================
Part (b)
See graph below. I recommend using your graphing calculator or some online free tool to get the job done. Doing this by hand would be a pain and it could lead to inaccuracies. I used GeoGebra to make the graph.
To get it done by hand, you basically plug in various t values to find corresponding h(t) values. This leads to generating points in which you draw a parabolic curve through them all.
==================================================
Part (c)
The graph from part (b) shows that the highest point is at (2,64), which is where point B is located.
This means that after t = 2 seconds, the largest height is reached at h(t) = 64 feet.
The rocket then takes another 2 seconds to go from the highest point back down to the ground.
The total time the rocket is in the air is 4 seconds. We could double the value t = 2, or note the distance between A and C on the x axis.

<h3>Answers:</h3>- max height = 64 feet
- time it takes to reach max height = 2 seconds
- total time rocket is in the air = 4 seconds
A primary health care provider diagnoses the client's condition as otitis media. Redness of the eardrum observed during examination by an otoscope supports that diagnosis.
An ear infection which is also known as acute otitis media is an infection of the middle ear, the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. Children are more susceptible to ear infections rather than the adults.
Symptoms of otitis media include ear pain, irritability, poor sleep, drainage from the ear, trouble in hearing, loss of appetite and fever. A healthy eardrum will be pinkish gray in color and translucent or clear. However, if the infection is present, the eardrum may be inflamed, swollen or red.
