Question

Algebra Help
Sean and Mason run out of gas while fishing. They set of an emergency flare with an initial velocity of 30 meters per second. The height of the flare in meters can be modeled by h(t)=-5t^2+30t, where t represents the number of seconds after launch.
1) Simplify the function so you can complete the square.
2) Sean wants to know how high the flare will reach above the waters surface.
A) write the function in vertex form, factoring so coefficient of t^2 is 1
B)Complete the square using the vertex form.
C) How high will the flare reach?
