What is the average rate of change for the function f(x)=3^x-9 9 less than or equal to x less than or equal to 11
sattari [20]

The average rate of change of a function f(x) in the interval [a,b] is defined as

A(a,b,f) = \dfrac{f(b)-f(a)}{b-a}

So, in your case, we have

A(9,11,3^x-9) = \dfrac{(3^{11}-9)-(3^9-9)}{11-9} = \dfrac{3^{11}-3^9-9+9}{2} = \dfrac{157464}{2}=78732

The table shows conversions of common units of length.
fgiga [73]

Answer:

0.50 miles


Step-by-step explanation:

<em>We can use two unit converters to solve this problem.</em>

  • 1 mile = 1.61 kilometers, and
  • 1000 meters = 1 kilometers

<em>Thus, we can setup the ratio below and solve:</em>

800 Meter*\frac{1Kilometer}{1000Meter}*\frac{1Mile}{1.61Kilometer}\\=\frac{800*1*1}{1000*1.61}Mile\\=\frac{800}{1610}Mile\\=0.497Mile

Rounding to 2 decimal places, 800 meters = 0.50 miles.
