Answer:After 2 seconds the object reach its maximum height of 80 feet.
Step-by-step explanation:
Consider the provided function.
The function is a downward parabola.
The object will reach its max height at the vertex of the parabola.
The vertex of the parabola is given by ,
Where the standard form is .
By comparing the provided function with the standard form.
a=-16, b=64 and c=16
Thus, the vertex are:
Now substitute the value of t in the provided function.
Hence, after 2 seconds the object reach its maximum height of 80 feet.

Answer:The horizontal area enclosed by the waterline of the ship is 12,797.88m2
Explanation: Mass of the ship=29000kg
Total mass of 50 ships= 50×29000
Total Mass=1450000kg
Volume of water with mass= mass/ density
Assuming density of ocean water =1030kgm3
Volume=1450000/1030
Volume=1407.77m3
Area enclosed by the ship =A=V/h
h=11cm=0.11m
Area= 1407.77/0.11
Area=12,797.88m2
