Explanation:
We need to prove that : [tex]\cos^2\theta+\cos^2\theta {\cdot} \cot^2\theta=\cot^2\theta[/tex]
Taking LHS : [tex]\cos^2\theta+\cos^2\theta {\cdot} \cot^2\theta[/tex]
Taking [tex]\cos^2\theta[/tex] common as follows :
[tex]\cos^2\theta(1+ \cot^2\theta)[/tex] ...(1)
We know that :
[tex]cosec^2\theta-\cot^2\theta=1\\\\cosec^2\theta=1+\cos^2\theta[/tex] ....(2)
Use equation (2) in equation (1) as follows :
[tex]\cos^2\theta{\cdot} cosec^2\theta[/tex]
We know that : [tex]cosec\theta=\dfrac{1}{\sin\theta}[/tex]
So,
[tex]\cos^2\theta{\cdot} \dfrac{1}{\sin^2\theta}\\\\=\cot^2\theta[/tex]
=RHS
Hence, LHS = RHS

Answer:
got em blake the red head
Explanation:
Wire will always be stranded when it is larger than 6 AWG. Check more about American Wire Gauge below.
What is AWG rule about?The American Wire Gauge (AWG) is known to be a kind of standardized wire gauge system that are known to be widely used in all parts of the United States. It centers around the diameter of electrical wire.
Conclusively, AWG general rules of thumb states that for every 6 gauge one has to lower the wire diameter and as such, Wire will always be stranded when it is larger than 6 AWG.

Henry is given a task to divide a segment into six equal parts, using a triangle and a compass. How many arcs would he need to complete this task?
A. three
B. four
C. five
D. six
Answer:
The correct option is;
D. Six
Explanation:
In order to divide a segment into six equal parts using a triangle and a compass, we have
1) With one (hypotenuse) side of the triangle placed on the segment to be divided, draw a slant line along at an angle to the segment to be divided into six equal parts
2) With the compass set to a fixed width, draw six arcs on the line drawn above from the start point of the given segment
3) With a side of the triangle drawl a line from last arc drawn on the slant line to the end of the segment to be divided into six equal parts
4) With the triangle, draw lines from the other arc marks on the slant line to the segment to be bisected parallel to the line drawn from the last arc to the end of the segment to be divided into six equal parts
5) The parallel lines joining the slant line to the segment will divide the given segment into six equal parts.

Which sentence best describes a refrigerator?
A.
It extracts heat from a high-temperature system and loses the heat to a low-temperature system.
B.
It extracts heat from a high-temperature system, loses some of the heat to a low-temperature system, and does work at its output.
C.
It extracts heat from a low-temperature system using work at its input, and rejects heat to a high-temperature system.
D.
It extracts heat from a low-temperature system and retains all the heat.
Answer: it's not b but i'm pretty sure it's c
Explanation:
just took the test
The statement 'it extracts heat from a low-temperature system using work at its input, and rejects heat to a high-temperature system' BEST describes a refrigerator (Option C).
A refrigerator is a commercial device that transfers heat to the environment so its internal compartment is cooled, thereby keeping foods and drinks cool.This device (refrigerator) maintains things cool by pushing a refrigerant (i.e., a liquid) through a sealed thermally insulated system.In consequence, a refrigerator can also be considered as a storage system that maintains foods to a suitable temperature.In conclusion, the statement 'it extracts heat from a low-temperature system using work at its input, and rejects heat to a high-temperature system' BEST describes a refrigerator (Option C).

Your study space does not need to be quiet as long as you can ignore any noise coming from the space true or false?
Answer:
False
Explanation:
When you're studying, you need to make sure that you can focus properly. This means that you shouldn't be hungry or too full and that you should be well-rested, in a quiet room with good lighting and no distractions. Noise is never good when you need to memorize something. Some people can partially ignore it as long as it isn't too loud, but it will begin to bother them eventually. That's why it's better to study in a quiet room.

Which of the following has special properties that allow forces and pressure to be distributed evenly?
fluids, wells, aqueducts, energy
Answer:
Fluids
Explanation:
Fluids has special properties that allow forces and pressure to be distributed evenly within them.
Fluids are gases and liquids whose intermolecular forces of attraction are generally weak or non-existence.Therefore, when pressure is applied to them, it permeates evenly on all parts. Their ability to tend to randomness makes liquids and gases very viable for distributing pressure.Answer:
fluids
