The graph below shows the height through which an elevator travels, y, in x seconds: A graph is shown with x axis title as Time
Blababa [14]

Answer:

C. 10

Step-by-step explanation:

We are given a graph representing the height of the elevator with respect to time.

Since, we know that,

X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.

As, the coordinate points on the graph are given by,

(1,10), (2,20), (3,30) and (4,40).

So, the rate of change can be found out by solving, \frac{20-10}{2-1}=10.

Hence, the rate of change of the relationship is 10.

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.
yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.

Step-by-step explanation:

The average rate of change of the cost of a pack (r), in monetary units per year, is equal to the change in the average cost of a pack (\Delta c), in monetary units, divided by the change in time (\Delta t), in years. Then, the average rate of change is:

r = \frac{\$\,5.31-\$\,0.88}{2000-1980}

r = \$\,0.22\,\frac{1}{yr}

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.
