Answer:
a) -7 & b) -6
Step-by-step explanation:
Here,
a) x = 0
Solution ↦

b) x = -1
Solution ↦

Substitute p and q with the given numbers (6 and 5) then use pemdas
18+42/6-5= 20
Like 8÷48 or 6÷48? like that
Exterior angle = 360/25 = 14.4 degrees
internal angle = 180-14.4 = 165.6 degrees
sum of all the angles = 165.6*25 = 4140 degrees answer
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_
