I’m sure the missing term is 90
Answer:
• (a)1320.5 thousand per year
,
• (b)f(x)=1320.5x+10602
,
• (c)f(7)=19846 thousand
Explanation:
Sales in the year 2009 = 10,602 thousand
Sales in the year 2013 = 15,884 thousand.
(a)Average rate of change (slope) from 2009 to 2013.
![\begin{gathered} =\frac{15,884-10,602}{2013-2009} \\ =\frac{5282}{4} \\ =1320.5\text{ thousand per year} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D%5Cfrac%7B15%2C884-10%2C602%7D%7B2013-2009%7D%20%5C%5C%20%3D%5Cfrac%7B5282%7D%7B4%7D%20%5C%5C%20%3D1320.5%5Ctext%7B%20thousand%20per%20year%7D%20%5Cend%7Bgathered%7D)
(b)If x is the number of years since 2009 and f(x) is the number of vehicles sold
When x=0, f(x)=10,602 thousand
The slope-intercept form of the equation of a line is: y=mx+b
![\begin{gathered} 10602=1320.5(0)+b \\ b=10602 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2010602%3D1320.5%280%29%2Bb%20%5C%5C%20b%3D10602%20%5Cend%7Bgathered%7D)
The equation of the line through these two points is:
![f(x)=1320.5x+10602](https://tex.z-dn.net/?f=f%28x%29%3D1320.5x%2B10602)
(c)Number of vehicles sold in 2016.
2016-2009=7
Therefore, when x=7
The number of vehicles sold, f(x) will be:
