Answer:
There are 5280.10 feets in 1 mile.
Step-by-step explanation:
Initial altitude of an airplane = 20,000 feet
Final altitude of an airplane = 10,000 feet
Drop in an altitude of an airplane = 20,000 feet - 10,000 feet = 10,000 feet
Drop in an altitude of an airplane read by radar traffic control is 1.8939 miles
1 mile = 5280.10 feets

Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:
Recall that the vertex is given by the formulas:
In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:
To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:
In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
