Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,

Hence, this is the required solution.
Answer:
A. a is where performance is minimal
Step-by-step explanation:
b is representing peak performance.
.95 in decimal form and 95/100 as a fraction or 19/20
M 7=280. you just multiply 7 by 40 to get your answer. i am pretty sure.
