Answer:
Average rate of change = 0.4
Step-by-step explanation:
Average rate of change of a function in the interval [a, b] is defined by the formula,
Rate of change =
From the table attached,
Rate of change of the function in the interval 20 ≤ x ≤ 40 will be
=
=
=
=
= 0.4
Therefore, average rate change of the function in the given interval 20 ≤ x ≤ 40 is = 0.4

Answer: 9(3 + 2r)
<u>Step-by-step explanation:</u>
27 18r
∧ ∧
<u>3</u> 9 <u>2</u> 9r
∧ ∧
<u>3</u> <u>3</u> <u>3</u> <u>3r</u>
27: 3 * 3 * 3
18r: 2 * 3 * 3 * r
Common Factors are 3 * 3 = 9
27: 9 * <u>3</u>
18: 9 * <u>2r</u>
27 + 18r = 9(3 + 2r)
