Answer:
(You only need to give one solution)
Step-by-step explanation:
We have the following equation
First, we need to foil out the parenthesis
Now we can combine the like terms
Now, we need to factor this equation.
To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.
The pair of numbers that would do this would be 1 and -4.
This means that our factored form would be
As the first binomial is a difference of squares, it can be factored futher into
Now, we can get our solutions.
The first binomial will produce two complex (Not real) solutions.
So our solutions to this equation are
Percentage is the way to represent the part of a whole in a fraction of 100.The greatest percent of the increase in the number of jobs from 2006 to 2016 is orthodontist which is 10.94 percent.
<h3>Given-</h3>In the given table we have to find out the percent of the increase in the number of each job to find out the greatest one.
<h3>Percentage</h3>Percentage is the way to represent the part of a whole in a fraction of 100.
1-Orthodontist-
In 2006 the total number of orthodontists was 9206.
In 2016 the total number of orthodontists was 10214
Percent of increase in this job is,
Hence, percent of the increase in this job is 10.94 present.
2-Sound engineer technician-
In 2006 the total number of Sound engineer technicians was 16125
In 2016 the total number of Sound engineer technicians was 17864
Percent of increase in this job is,
Hence, percent of the increase in this job is 10.78 percent.
3-Police officer-
In 2006 the total number of Police officers was 648982
In 2016 the total number of Police officers was 719041
Percent of increase in this job is,
p_{3} =10.79%
Hence, percent of the increase in this job is 10.79 percent.
4- Editor-
In 2006 the total number of Editors was 122273
In 2016 the total number of Editors was 124135
Percent of increase in this job is,
Hence, percent of the increase in this job is 1.52 percent.
Hence, the greatest percent of the increase in the number of jobs from 2006 to 2016 is orthodontist which is 10.94 percent.
