Answer:

Step-by-step explanation:

The answer is A: <em>c<11</em>

This is because the required amount of chaperones is 11 because the total number of students (121) divided by the required number of students per chaperone (12) is results in 10 remainder 1, and 11 required chaperones.

If the school does not have have enough chaperones that means they must have less than 11 chaperones, so the answer is c (the number of chaperones) is less than 11.

What is the average rate of change for the function f(x)=3x^2 -5 on the interval −3 ≤ x ≤ −1 ?
Anestetic [448]

Answer:

-12

Step-by-step explanation:

Let b = -1 and a = -3

The average rate of change = \frac{f(b) - f(a)}{b - a}

f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2

f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22

f(b) - f(a) = -2 - 22 = -24

b - a = -1 + 3 = 2

\frac{f(b) - f(a)}{b - a} = -24/2 = -12
