Answer: odd
Step-by-step explanation:
Given
The graph of a function increases as x increases and decreases as x decreases.
This shows that the degree of the polynomial is odd
for example
Here, the leading coefficient is positive, and the value of function increases as x increases and vice-versa.
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_
