Red aerial mini-flares are used by some boaters in an emergency. The flight of one brand of flares, when fired the function is modeled by h(t)= -16t^2+84t+3. How many seconds does it take for the flare to reach it's maximum height? What is the height reached by the flare after 4 seconds?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

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: need a picture

they aren't great and cause destruction, idk man
