Answer:

3

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 0, 2 ] and from the graph

f(b) = f(2) = 0

f(a) = f(0) = - 6, hence

average rate of change = \frac{0-(-6)}{2-0} = \frac{6}{2} = 3

A 20 foot rope is cut so that one piece is 5 feet longer than the other. Find the length of each piece
hammer [34]

Let one piece of the rope be x

Let the other piece of rope be x + 5

These two pieces put together will make 20 feet.

So we say:

x + (x +5) = 20

What is x? We expand the equation.

x + x + 5 = 20

x + x = 20 - 5

2x = 15

x = 7.5

The shorter piece is  therefore 7.5 feet.

The longer piece is 7.5 + 5 = 12.5 feet.
