The population of Detroit, Michigan, decreased from 1,027,974 in 1990 to 688,701 in 2013 (Source: U.S. Census Bureau). Find the
AleksandrR [38]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of any straight line, we simply need two points off of it, so let's use the ones provided in that

\begin{array}{|cc|ll} \cline{1-2} \stackrel{years}{x}&\stackrel{population}{y}\\ \cline{1-2} 1990&1027974\\ 2013&688701\\ \cline{1-2} \end{array}\hspace{5em} (\stackrel{x_1}{1990}~,~\stackrel{y_1}{1027974})\qquad (\stackrel{x_2}{2013}~,~\stackrel{y_2}{688701}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{688701}-\stackrel{y1}{1027974}}}{\underset{run} {\underset{x_2}{2013}-\underset{x_1}{1990}}} \implies \cfrac{-339273}{23}\implies -14751\qquad \stackrel{rate~of}{change}

let's notice, is negative since the population decreased.

Answer:

2 : 1

Explanation:

\sf area \ of \ sector: \dfrac{\theta}{360} \pi r^2

<u>1st sector</u>:

\sf \rightarrow area: \dfrac{80}{360} \pi (8)^2  = 44.68 \ cm^2

<u>2nd sector</u>:

\sf \rightarrow area: \dfrac{160}{360} \pi (4)^2  = 22.34 \ cm^2

Ratio of 1st sector to 2nd sector:

44.68 : 22.34

2 : 1
