*SOMEONE WHO CAN SIMPLY ORDER INTERVALS!*

The table represents the height of a rock thrown off the side of a bridge that is 96.44 feet above ground level for the first 0.60 seconds. Find the average rate of change for each interval and order the intervals from least to greatest rate of change.

Time (seconds) (left) / Height (feet)(right)

0.00 / 96.44

0.10 / 97.60

0.30 / 98.57

0.60 / 98.30

Answer:

Step-by-step explanation:

The time intervals are [0.00, 0.10], [0.10, 0.30], and [0.30, 0.60].

The rate of change in each interval is the slope of the line between the endpoints:

m = [f(b) − f(a)] / (b − a)

Filling out the table:

[tex]\left[\begin{array}{ccc}Time (s)&Height (ft)&Rate\ of\ change(ft/s)\\0.00&96.44\\&&\frac{97.60-96.44}{0.10-0.00}=11.6 \\0.10&97.60\\&&\frac{98.57-97.60}{0.30-0.10}=4.85\\0.30&98.57\\&&\frac{98.30-98.57}{0.60-0.30}=-0.90\\0.60&98.30\end{array}\right][/tex]

The intervals are already in order from greatest to least.  Simply reverse the order to get least to greatest:

[0.30, 0.60]

[0.10, 0.30]

[0.00, 0.10]

Based on the information given, it should be noted that the average rate of change will be 11.6, 4.85, and -0.90.

Rate of change.

From the information given, it should be noted that the time intervals have already been provided.

Therefore, the rate of changes will be:

= (97.60 - 96.44)/(0.10 - 0.00) = 11.6.

= (98.57 - 97.60)/(0.30 - 0.10) = 4.85

= (98.30 - 98.57)/(0.60 - 0.30) = -0.90

Therefore, the average rate of change will be 11.6, 4.85, and -0.90.
