Answer:
Density = 10,490 g/m³
Step-by-step explanation:
Density = mass ÷ volume
here mass = 73,430 g
volume = 7 m³
density = 73,430 ÷ 7
= 10490 g/m³
Density = 10,490 g/m³
Use the Pythagorean theorem:

Answer:
a) The debris was 256 feet into the air after 2 seconds of the explosion.
b)

Step-by-step explanation:
We are given the following in the question:
Initial Velocity = 160 feet per second

The above function gives the height in feet and t is seconds after the explosion.
a) Height of the debris 2 second(s) after the explosion.
We put t = 2 in the above function

Thus, the debris was 256 feet into the air after 2 seconds of the explosion.
b) Factor the polynomial
