Answer:
3 is the root of the equation.
Step-by-step explanation:
We have to find the root of the polynomial equation x(x-2)(x+3)=18.
We can find the same by using a graphing utility and the system of equations.
We can make two equations which are given by
Now, we plot the graph of these equations and the x-coordinate of the intersection point will be the root of the equation.
the graph has been shown in the attached file.
The intersection point is (3, 18) and the x-coordinate is 3.
Therefore, 3 is the root of the equation.
The correlation coefficient is defined as the degree of <u>linearity</u> between two <u>quantitative</u><u> </u> variables.
<h3>What is Correlation Coefficient</h3>
Th association between two quantitative variables is measured by the correlation coefficient.
Thus, correlation coefficient, r, which ranges from 1 to -1, it shows the strength of linear association between two random variables that are normally distributed.
In summary, the correlation coefficient is defined as the degree of <u>linearity</u> between two <u>quantitative</u><u> </u> variables.

Answer:
5.1 inches
Step-by-step explanation:
Five triangles make up the pentagon.
The area of each is aside
The area of the pentagon is 5
Substitute values and calculate
Hi friend,
((5+a)/a)/((a^2 -25) /5a)
=(a+5)/((a^2 - 25)/5)
=(a+5)(5)/(a+5)(a-5)
=5/(a-5)
Therefore your answer is B)
Hope this helps you!
