Answer:
Velocity of jet in still air is 800mph hour and velocity of wind is 180mph
Step-by-step explanation:
Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.
#Jet's velocity against jet-stream is:
#Jet's velocity with jet-stream:
#The velocity against jet-stream is x-y and with jet-stream is x+y:
Hence,velocity of jet in still air is 800 mph hour and velocity of wind is 180 mph.

Answer:
(2, 3)
Step-by-step explanation:
Compare the given equation ...
y = (x -2)^2 +3
to the vertex form ...
y = (x -h)^2 +k
You can see that h=2 and k=3.
The vertex of the parabola is (h, k) = (2, 3).
