Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.

Is this the actual question
Answer:
∠XBA=43°
Step-by-step explanation:
we know that
If ray BA bisect angle ∠XBY
then
∠XBA=∠XBY/2
we have
∠XBY=86°
substitute
∠XBA=86°/2=43°
