Answer:
The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
Step-by-step explanation:
Due to the assumption of a yearly average rate, a linear function model shall be used. The expected amount of jobs (
) after a certain amount of years (t) is given by the following formula:
Where:
- Initial amount of jobs in pipe fitting industry, measured in thousands.
- Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)
If 
, 
and 
, then:
The percent change in jobs from pipe fitting industry is calculated as follows:
The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
It is decreasing percentage at 40%
The equation you’re using here would be:
1300(1.04)^x.
After 3 years, you’d plug in 3 for the value of x.
The amount of money in the bank after 3 years would be $1,462.32.
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
The equation of the line that passes through the point (4,-4) and has a slope of -3 is y = -3x + 8.
<h3>How to find the equation of a line?</h3>
The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
Therefore, the equation of the line that passes through the point (4,-4) and has a slope of -3 can be found as follows;
m = -3
Hence,
y = -3x + b
using (4, -4) let's find the y-intercept.
-4 = -3(4) + b
-4 = - 12 + b
b = -4 + 12
b = 8
Therefore, the equation is y = -3x + 8
