Answer:

C. [tex]1.90\leq x \leq 2.10[/tex]

Explanation:

The question states that x has is value in between and including 1.9 and 2.1. So the number is greater than or equal to 1.9 but less than or equal to 2.1.

In option A [tex]x\geq 2.1[/tex] this means that the value of x is greater than or equal to 2.1 which does not satisfy the condition mentioned in the question

In option D [tex]x[/tex] is greater than or equal to 2.1 but less than or equal to 1.9 which does not satisfy the condition mentioned in the question.

In option C [tex]x[/tex] is greater than or equal to 1.9 and less than or equal to 2.1 which does satisfy the condition mentioned in the question.

So, option C is correct.

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.

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

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.

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.
