Answer:
b
Step-by-step explanation:
20 + 30 + 25 + 15 + 25 = 115
115 / 5 = 23
20 - 23 = |-3|
30 - 23 = 7
25 - 23 = 2
15 - 23 = |-8|
25 - 23 = 2
3 + 7 + 2 + 8 + 2 = 22
22/5 = 4.4
(1/2) * x^3 + 3.4y when X = 2 and Y = 5.
= (1/2) * (2^3) * 3.4(5)
= (1/2) * 8 * 17
= (1/2) * 136
= 136/2
= 68.
Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change =
=
= 12
