Answer:
Step-by-step explanation:
**Note: The polynomial in question is -16t² + 160t, as clarified in the discussion under the question.**
Since there is a polynomial to find the height given a certain time, the height is a function of time.
This function would be h(t) = -16t² + 160t, so plugging in 4 for t would give the height.
<em>[Squaring 4]</em>
<em /> <em>[Multiplying]</em>
<em /> <em>[Combining both terms]</em>
Hence, the <u>height</u> of the firework after 4 seconds is 384 feet.

Answer:
0.220 L
Step-by-step explanation:
One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:
2.220 L - 2 L = 0.220 L

The nice thing about metric units is that conversion factors are often powers of 10, so only movement of the decimal point is required. It can be worthwhile to become familiar with the SI prefixes.
