Answer:
x = 16
Step-by-step explanation:
= 2 [multiply both side by 8]
x = 16
Evaluate the function at 2. That is f(2).
Evaluate the function at 0. That is f(0).
the average rate of change from 0 to 2 is (f(2) - f(0))/(2 - 0)
f(x) = 120(0.1)^x
f(2) = 120(0.1)^2 = 120 * 0.01 = 1.2
f(0) = 120(0.1)^0 = 120 * 1 = 120
average rate of change = (1.2 - 120)/(2 - 0) = -118.8/2 = -59.4
Answer: 15 boxes
Step-by-step explanation:
From the question, we are informed that Denise wants to cover a 21.75 square foot wall with weathered wood and that each box of weathered wood contains 1.5 square feet of wood.
The number of boxes of weathered wood that she need will be calculated by dividing 21.75 square feet by 1.5 square feet. This will be:
= 21.75/1.5
= 14.5
= 15 boxes approximately
