Question 1159584: Please help me solve this equation.
The height h of a missile after t seconds, when fired straight up with an initial height of 2 feet, can be modeled by the function h(t)=-16t^2+150t+2
A.) When will the missile be 250 feet?
B.) When will the missile be at it's maximum height?
C.) What is the maximum height of the missile?
D.)Will the missile ever reach a height of 400ft? Answer by MathLover1(20849) (Show Source):
The height of a missile after seconds, when fired straight up with an initial height of feet, can be modeled by the function
A.) When will the missile be feet?
-> ......use quadratic formula
solutions:
-> ->
fired straight up the missile will be feet high in seconds, and on way back again in seconds
B.) When will the missile be at it's maximum height?
if is negative, the parabola opens down and maximum is at vertex
so, write your equation in vertex form:
.....complete square
......
-> and
vertex: (,)
the missile will be at it's maximum height in seconds
C.) What is the maximum height of the missile?
D.)Will the missile ever reach a height of ?
.......check discriminant
If the equation has real number solutions, but it does have complex solutions
-> true
so, the missile will never reach a height of
