The phrase gives you an interval where the extremes are included.
The intervals may be indicated in several ways.
7.2 ≤ x ≤ 7.6
Step-by-step explanation:
Using pythagoras theorem
9^2 - 6^2 = x^2
Therefore X^2 = 81 - 36
= 45
Thus X = √45
X = 6.71
1,009.479 just add themmmm
If you are doing any scientific notation to the negative power the answer will be a decimal. In this case you will move the decimal point four places to the left.
The answer will be 0.0002077
