Solve the Problem $$F ( t ) = \frac { 5 ( t - 10 ) ^ { 2 } - 19 } { 20 ( t - 10 ) ^ { 2 } - 10 ( t - 10 ) + 16 }$$

Multiple Choice

Solve the problem.
-A plane suddenly experiences turbulence while in flight. At this point the change in its altitude, in feet, is represt the following function of time:
$$F ( t ) = \frac { 5 ( t - 10 ) ^ { 2 } - 19 } { 20 ( t - 10 ) ^ { 2 } - 10 ( t - 10 ) + 16 }$$
Assuming that the turbulence first hits at time $t = 0$ , what is the maximum relative drop the plane will experienc due to turbulence? (Round the result to the nearest hundredth.)

A) $0.25 \mathrm { ft }$ .
B) $28.19 \mathrm { ft }$ .
C) $1.27 \mathrm { ft }$ .
D) $10.21 \mathrm { ft }$ .
