Answer:
3
Step-by-step explanation:
The average rate of change is
f(x2) - f(x1)
-----------------
x2-x1
We want to find the change from 1 to 3
f(3) = 8
f(1) = 2
f(3) - f(1) 8-2 6
----------------- = ------------ = ---- = 3
3-1 2 2

Answer:
m∠LOM=48°
Step-by-step explanation:
∠LON=180° AND ∠LON=∠LOM+∠MON
⇒ 7x-92+6x+12=180
⇒13x=180+92-12
⇒x=20
m∠LOM=7x-92°=140°-92°=48°
Every foot is composed of 12 inches. Below is the way to solve the number of inches (n) in 12 ft.
n = (12 ft) x (12 inches / 1 ft) = 144 inches
To determine the number of 2-inch segments, divide 144 inches by 2. The division gives an answer of 72. Thus, there are 72 2-inch segment in 12 ft.
