Helpppppp me pleaseeeeeee!!!!!!!!
Nimfa-mama [501]

Answer:

Step-by-step explanation:

think of the flight of a small rocket..  what does it seem like the parabola would look like?  down means it looks like a cup or glass , upside down , up mean a cup or glass right side up.

when t = 0  the rocket is at 25, so that's the initial height

it's velocity is initially 200 m/s

put equation from std. form to vertex form

y = ax^{2} + bx +c       =>       y = a(x - h ) ^2 + k

h = -4.9t^{2} + 200t + 25  =>h = -4.9(t - 20.41)^2 + 2,065.82

(h,k) =  (20.41 , 2065.82)

x = ± 2i\sqrt{3}

Step-by-step explanation:

note that \sqrt{-1} = i

x² = - 12 ( take square root of both sides )

x = ± \sqrt{-12} = ± \sqrt{4(3)(-1)} = ± 2i\sqrt{3}
