Me and the other people in the room
Explanation:
Silicon is a chemical element with the symbol Si and atomic number 14.
Answer:
1) The angle would be 150 degrees
a) coordinates would be (
,
)
b) Trigonometric ratios:
sin: 
cos:
tan: 
csc: 2,
sec:
cot: 
Explanation:
simplifys to
which has a reference angle of
. We can take the coordinates of
and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
The answer would be: Intake, Compression, Power, and Exhaust.
<span>Intake: also known as induction or suction.
Compression: starts at the end of the suction stroke, and ends at T.D.C.
<span>Power: also known as combustion. This is the start of the second revolution of the four stroke cycle.
</span><span>Exhaust: also known as outlet. In here, the piston once again returns from B.D.C. to T.D.C. while the exhaust valve is open. This action eliminates the spent air-fuel mixture through the exhaust valve.</span></span>
