The given problem can be exemplified in the following diagram:

The perimeter of a figure is the sum of all of its sides, therefore, the perimeter of the figure is:

$P=18ft+18ft+9ft+9ft$

Adding the terms:

$P=54ft$

therefore, the perimeter is 54 feet.

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −10 to x = 10.

igor_vitrenko [27]

The average rate of change formula is
f(b) - f(a)
arc = ----------------
b-a

Here, a= -10 and b = 10

(10)^2 + 9(10) + 18 - [ (-10)^2 + 9(-10) + 18]
Here arc = --------------------------------------------------------------
10 - (-10)

10^2 and -(-10)^2 cancel. 18 - 18 cancel.

90 - (-90) 180
This leaves us with arc = ----------------- = ------------- = 9 (answer)
