Answer:

C

Step-by-step explanation:

f"(x) < 0, which means the function is concave down at all values of x.

For any such function, within the domain of a ≤ x ≤ b, the secant line S(x) is below the curve of f(x), and the tangent line T(x) is above the curve of f(x).

Here's an example:

Sara works for 40 hours a week. She attends meetings for 0.28 of the time she is working. How much time does Sara spend at meeti
Roman55 [17]

Answer:

11.2 hours or 11 hours 12 minutes

Step-by-step explanation:

In this question, we are to calculate the amount of time spent by Sara in attending meetings weekly.

In the question, we are made to understand that she attends a meeting at a rate of 0.28 multiplied by the total amount of time she works.

To get the time she attends the meeting, we only need to multiply the decimal by the number of hours she works

Mathematically that would be 0.28 * 40 = 11.2 hours per week

We might take it further to get the time in the format of hours and minutes. That would be 0.2 * 60 yo convert the hours to minutes. This gives 12 minutes .

She attends meeting 11 hours 12 minutes per week
