Answer: The square root is: 4.243
Step-by-step explanation:
Here are table and graph on the same page.
_____
The parent absolute value function is expanded vertically by a factor of 2, then translated right 4 units and up 3 units.
Let p and w represent the speed of the plane and the speed of the wind, respectively.
.. speed = distance/time
.. p +w = 720/3 = 240
.. p -w = 720/4 = 180
Add the two equations to eliminate w.
.. 2p = 420
.. p = 210
.. w = p -180 = 30
The speed of the wind is 30 mph.
The speed of the plane in still air is 210 mph.
Answer:
48÷8 = 6
Therefore the answer is 6/1 or just 6
