Given fx) = 17- x2, what is the average rate of change in f(x) over the interval [1, 5]?
Andrei [34K]

Let [a, b] = the interval

The average rate of change can be found by using [f(b) - f(a)]/(b - a).

Let a = 1 and b = 5.

Let R = rate of change

17- x^2

R = [17 - 5^2] - [17 - 1^2]/(5 - 1)

R = [17 - 25] -[17 - 1]/4

R = [(-8) - (16)]/4

R = (-24)/4

R = -6

Done.

Last question please help me
gladu [14]

Make a 4x4 table where rows are Alice, Bart, Pamela, and Robert, and where columns are the professions: Dentist, Laywer, Teacher and Writer.

Start crossing out possible pairing person-profession using the facts given. When a job is clearly assigned, you can cross it off for the rest of the people, for example, Pamela is a dentist so none of the rest are a dentist (because we are told they have all different jobs).

Eventually your table becomes filled.

Alice is a Lawyer

Bart is a Writer    <<< so this is choice (B) for your answer

Pamela is  a Dentist

Robert is a Teacher

Let me know if you have questions
