Answer: Carbon
Step-by-step explanation:
Carbon is considered to be the building block of all living things as it is very important in the formation of compounds that are needed by living things to survive such as Carbohydrates and Protein and many more.
This is down to its ability to form stable compounds with other elements such as Hydrogen and oxygen both of which are present in Carbohydrates and Proteins.
Carbon exists in the Earth's crust as Carbonates in water, rocks, petroleum and living things as well especially plants and trees which release a significant amount if they are cut down.
If you are asking what x to the power of 2 minus x is as a mathematical expression, then your answer is:
= x^2 - x
If you are asking what another equivalent expression for x^2 - x is or if you want it in factorised form, then your answer is:
= x ( x - 1 )

Answer:
53°, 127°, 127°
Step-by-step explanation:
<u>Two intersecting lines form two pairs of angles:</u>
- Pair of vertical angles. They are opposite to each other and are equal
- Pair of adjacent angles which are supplementary angles and their sum is 180°
<u>So if one of the angles is measured 53°, then the other angles are:</u>
- 53°- vertical angle with the first one
- 180° - 53° = 127°
- 180° - 53° = 127°
So here are the rules of horizontal asymptotes:
- Degree of Numerator > Degree of Denominator: No horizontal asymptote
- Degree of Numerator = Degree of Denominator:
- Degree of Numerator < Degree of Denominator: y = 0
Looking at the rational function, since the degree of the numerator is 2 and the degree of the denominator is 1 (and 2 > 1), this means that <u>this function has no horizontal asymptote.</u>
An arc of length 30 m : l = 30 m.
r = 15 m, ∠ A = ?
Formula for the length of an arc is:
l = r π A / 180° ( where A is the central angle )
A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 °
This is very close to your result.
