Answer:
8.0023x 10^4
Step-by-step explanation:
80023
to get to the first place number you have to move the decimal 4 times and if it looked like this .80023 it would be 10^-1 going down moving places back wards
Answer:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_


Step-by-step explanation:
In this problem the amplitude of the sinusoidal function is given by the length of the blades.

The mill is 40 feet above the ground, therefore the function must be displaced 40 units up on the y axis. So:

We know that the blades have an angular velocity w = 3 rotations per minute.
One rotation = 
1 minute = 60 sec.
So:


Finally:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_


So a mile has 5280 feet.
21,129/5280= 4 mph
multiply
4 x 2 = 8 miles in 2 hours
