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

Answers

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.

Match the military operation to the category of satellite that would perform it.

location of enemy ground troops
routine reconnaissance of an unfamiliar climate
analyze waterways in an unfamiliar location
provide warning of an attack

Earth observing weather navigation communication

Answers

Answer:

1. Location of enemy ground troops  - EARTH OBSERVING.

Using earth observing satellite imagery, the military can observe vast expanses of land and in so doing, find the location of enemy ground troops.

2. Routine reconnaissance of an unfamiliar climate  - WEATHER

In other to find out more about the climate of an area, a weather satellite can be used to observe the areas and its changing weather patterns.

3. Analyze waterways in an unfamiliar location  - NAVIGATION

Using navigation satellites, navigation conduits such as roads and waterways can be observed.

4. Provide warning of an attack - COMMUNICATION.

Communications satellites enable people to communicate over great distances and so can be used by the military to warn of an impending attack.

cos square there + cos square theta multiply cot square theta = cot square theta​

Answers

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

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.

Answers

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).
