Answer:
<h3>C. Scientific Notation</h3>
Step-by-step explanation:
Since the number in question is greater than or equal to 1 but less than
10, we can choose any number between 1 and 10, lets take 3 for example.
If we take the product of 3 and an integer power of 10 number without regard to its sign, this can be expressed mathematically as shown;
where the power of 10 is -5. Note that any real number can be used as the power since we are not regarding the sign (Here we used -5). The expression formed according to the expression in question is a SCIENTIFIC NOTATION i.e gives us a scientific notation.
<em>Scientific notation is a means by which we represent very large or small numbers that are difficult to represent using a decimal notation</em>
<span>3x - 5 < 4.
Add 5 to both sides,
3x < 9
Divide 3 from both sides,
x < 3

Divide 315,530,612 by 3,539,225 to get 89 people per square mile (rounded)
Given:
The equation of ellipse is
To find:
The length of the minor axis.
Solution:
The standard form of an ellipse is
...(i)
where, (h,k) is center, if a>b, then 2a is length of major axis and 2b is length of minor axis.
We have,
...(ii)
On comparing (i) and (ii), we get
Taking square root on both sides.
Consider only positive value of b because length cannot be negative.
Now,
Length of minor axis = 
= 
= 
So, the length of minor axis is 8 units.
Therefore, the correct option is B.
Answer:
120 is the y intercept in the formula y=mx+b
