Two missiles, A and B, are shot from two different launch pads. The path of missile A can be represented by the quadratic function A(t) = −(t − 23)^2 + 905, where height, A(t), is in meters, and time, t, is in seconds. The path of missile B is shown below.
Part A: Which missile reaches the highest altitude (in meters)? Explain your answer.

Part B: How much higher does it travel (rounded to the nearest tenth)? Show all work necessary.

You need to find the vertex for missile A

kiki99 · Answer

can you just give me the answer please im running out of time :(

phi · Answer

A(t) = −(t − 23)^2 + 905
is a parabola in vertex form.  What is the vertex ?
to find it you match it with
y =  a(x-h)^2 + k
and the vertex is (h,k)

phi · Answer

The answer is the missile with the biggest "y" value in the vertex. i.e. the k in (h, k)
You can read the k value for missile B from the graph... they labeled the vertex

for A, yo have to pick out the h number using the equation.
