Answer:

- 2

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

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

here [ a, b ] = [ - 1, 1 ]

f(b) = f(1) = 1 - 2 = - 1

f(a) = f(- 1) = 1 + 2 = 3

Hence

average rate of change = \frac{-1-3}{1-(-1)} = \frac{-4}{2} = - 2

The answer is 2. The rate of change between -1 and 0 is 3 and between 0 and -1 is 1. The average between 3 and 1 is 2.

The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.
Sindrei [870]

Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.
