Question

Mikalee, a fighter pilot, ejects from her burning plane. Once she is safely on the ground, she launches a flare to attract the attention of a rescue plane. The initial velocity of the flare is 1600 ft/sec. The path of the flare is represented by the function h(t) = - 16t^2 + 1600t where t is the time in seconds and h(t) is the height of the flare.

What is the maximum height of the flare?


400 ft


4000 ft


40,000 ft


50 ft

Answer 1

Vertex.

Answer 2

maximums are on vertices.

Answer 3

That doesn't make any sense

Answer 4

Not now, it doesn't. How about a nice formula? It's called the vertex formula. :)

Answer 5

.. huh..

Answer 6

Okay... the equation of the position of the flare is quadratic, right? :)

Answer 7

i already got the answer
