Answer:
a=10 and b= -12
Step-by-step explanation:
Answer:
7x+80
Step-by-step explanation:
7 times everything in the () and get
56+7x+24
combine like terms
7x+80
8.04 * 100= 804
You move the decimal point two times to the right
8.04*101=812.04
The table that shows a ratio of y to x as 8:1 is C.
This comes from the fact every value of y is 8 times the value of x given.
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_
