Hayden is playing with a toy airplane. The height of the airplane, in metres, is given by the relation h=-3t^2+48, where t is the number of seconds since the plane was
launched.
a) For how long will the airplane be in the air?
b) Determine the time when it reaches its maximum height? What is the maximum
height?
c) At what time(s), rounded to the nearest tenth of a second, will the airplane reach a
height of 30 m?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: $1794
