What is the average rate of change of the function f(x) = 5x ^ 2 + 20x between x = 0 and x = 0.5
1 answer:
9514 1404 393
Answer:
22.5
Step-by-step explanation:
The average rate of change on the interval [a, b] is the ratio ...
(f(b) -f(x))/(b -a)
For your function and interval, it is ...
(f(0.5) -f(0))/(0.5 -0)
Since f(0) = 0, this reduces to ...
average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)
average rate of change = 22.5

Answer:
20
Step-by-step explanation:
Let be equal to the number that 24 is 120% of.
Divide both sides by 1.2 to isolate
Therefore, 24 is 120% of 20.
