We use the given data above to calculate the volume of gasoline that is being burned per minute by commercial airplanes.
Amount burned of 1 commercial airplane = <span>3.9 × 10³ ml of gasoline per second
Number of airplanes = </span><span>5.1 × 10³ airplanes
We calculate as follows:
</span> 3.9 × 10³ ml of gasoline per second / 1 airplane (5.1 × 10³ airplanes)(60 second / 1 min ) = <span>1.2 x 10^9 mL / min</span>
3.1 miles per minute
Explanation/how to do it:
You first need to know how many minutes are in an hour. Which is 60 once you get that you multiply it by 3 because there’s 3 hours with 60 minutes and you want everything converted into minutes. You should get 180 then and then you divide it 558 and you should get 3.1 and that would be your answer
Part A is accomplished by first factoring out the b^2 to get

. Factor that completely using the quadratic formula to get

. Part B is done entirely with the quadratic formula (only cuz that's the easiest way to factor a second degree polynomial!) to get (x-9)(x-9) or (x-9) multiplicity 2. Part C is done by taking roots. Keep in mind that since this is a second degree polynomial you will have 2 solutions.

, therefore,

and

which is +11 and -11. And you're done! Factoring is very important...make sure you learn it and learn it well!!!
