Answer:
Both Hannah and Gus are correct.
Step-by-step explanation:
We are given the following information in the question:
Hannah says that 2.11 is a rational number. Gus says that 2.11 is a repeating decimal.
Hannah is correct in the claim as 2.11 can be written in the form of a fraction, where,
Hence, 2.11 is rational number.
2.11 is also a repeating decimal as it can be written as 2.110000...
- A repeating or recurring decimal is decimal a number whose digits after point are periodic and repeats.
- It can be shown that a number is rational if and only if its decimal expansion is repeating or terminating.
Hence, both Hannah and Gus are correct.

Answer:
D. 5
Step-by-step explanation:
From the information given:
The derivatives of functions and functions have a different average rate. The average rate expanded over an interval of two distinct point (a f(a)) and (b f(b)) is represented by the equation:
where; the two points are:
(-1 , f( -1) ) & ( 1, f(1) )
For f(1); we have:
f(1) = 1 +3(1)³ - 5(1)² + 2(1) - 2
f(1) = 1 + 3 - 5 + 2 -2
f(1) = - 1
For f( -1); we have:
(-1)⁴ + 3(-1)³ - 5(-1)²+2(-1)-2
= 1 - 3 - 5 -2 - 2
= -11
∴
= 5
