Answer:
Step-by-step explanation:
The last (fourth) graph is that of the parent function y = √x. The negative sign in front of √x leads to reflection of this parent function graph in the x-axis. Thus, the correct graph of f(x) = -√x is the first one.
A number (we will call X) times 8 Is 8x
The coordinates are (-5,1).
In 1 second it beats about 53 times
In 5 seconds it will beat about (53/1*5) times
= 265 times
Convert miles/hour to meters/second:
42mi/hr(0.447) = 18.77m/sec
