Answer:

Step-by-step explanation:
From the graph, the x-intercepts are;



These are root of the polynomial function represented by the given graph.
By the remainder theorem;

According to the factor theorem, if
is a factor of
, then 
This implies that;
are factors of the required function.
Hence; 
We expand using difference of two squares to obtain;

We expand using the distributive property to get;

Rewrite in standard form to obtain;

In order to solve the formula

in terms of d, you simply have to divide both sides by pi:

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

So, the total height is

The correlation coefficient between two variables, r, is always going to be between -1 and 1.
- If the correlation coefficient is 0, means that there is no strong correlation relationship in one direction or the other direction.
- If the correlation coefficient is -1, means that these two variables move in opposite directions.
- If the correlation coefficient is 1, means that these two variables move in the same direction.
Simply 8. 8 fits into 2 4 times.
