The answer is:

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.


Here's how:

The rate of change of the function is defined and calculated as (refer to the statement beloew):

r = [change in height] / {change in time]


For the Table:

refer to the attached picture.

The table shows the calculations for the rate of change (r) for each interval given.


And for the Conclusion,

Refer to the table and notice that in the third ans fifth columns show that:

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.

BaLLatris [955]

Answer:

An event with a probability of 0 is impossible.  

An event with a probability of 1 is certain.

Step-by-step explanation:

Probability is typically expressed in terms of a fraction between 0 and 1 where the denominator is the total number of outcomes and the numerator is the number of desired outcomes.  Since probability is expressed as a fraction, if the probability is 0, that means it is impossible, or there is no chance that the event can happen.  However, if the probability is 1, that means that the event is certain to happen and the odds are completely in your favor that the event will happen.
